My emails are not working, help!
In the vast majority of cases this is simply due to a bad DNS configuration. Please check out our DNS settings page. You might also find one of the following domain provider guides helpful:
To test your setup, have a look at "How do I know if my DNS is set correctly?" below.
If you're still in trouble, know that we offer to do the DNS configuration ourselves for our premium users. This requires for you to provide us with your registrar (i.e. domain provider) credentials though, so we can access your domain DNS editor.
The emails I send end up in the SPAM folders of my recipients!
If your (non SPAM) emails delivered but end up in your recipients' SPAM folders, this is most likely due to a misconfiguration (or lack thereof) of your DNS SPF record or your DNS DKIM record, or both.
To fix this, please see "How do I know if my DNS is set correctly?".
Another possibility is that your domain has a bad reputation, which often occurs when your domain email addresses send unsollicited emails. In this case, there is not much you can do, except to simply stop sending such emails to recover a good reputation. Any spammy email will also likely be detected and classified as SPAM regardless of the domain reputation.
How do I know if my DNS is set correctly?
If you've haven't verified your MX record yet, please visit https://www.postale.io/fr/configure/yourdomain.com to verify your MX record first (replace yourdomain.com with your actual domain name).
Once your MX record is verified, login to the admin interface with an administrator address and click on the DNS diagnostic button in your domain page. This will show you everything you need to know about your domain DNS settings and what you need to fix.
What's a DNS, and why do I need to configure it?
The Domain Name System is a service acting as a directory for websites and other internet services.
When you enter the name of a website in your web browser, say "google.com", your browser first asks to a DNS server where it can find that site (i.e. what's the IP address of the web server serving that particular site).
The same thing goes for emails. When you send an email to someone, say to "firstname.lastname@example.org", your mail client (Gmail, Outlook, ...) first asks a DNS server where to actually send the email (i.e. what's the mail server handling emails for "poupoupidou.com").
Thus, any domain with email addresses needs a DNS configuration. That configuration takes the form of textual records on DNS servers hosted by your domain provider.
If you're using postale.io for your domain emails, you need to set your domain DNS records so that mail clients everywhere in the world know that emails sent to your domain are handled by postale.io mail servers. Usually, only people knowing the domain provider (a.k.a registrar) credentials used to purchase a domain name have the ability to edit the DNS records of that domain.
The main DNS record for emails is called an "MX" (Mail eXchange) record. For websites, it's called an "A" record. There are many more records for different purposes.
What's an MX record?
It's the DNS record for mail servers. It tells what mail server(s) handle emails for a given domain name. That record is absolutely required to have working domain email addresses.
To know the right MX record you need in order to use postale.io, please have a look at the DNS configuration guide. More information about MX records can also be found in our blog post "The MX Record Explained".
What's an SPF record?
This is another DNS record used for emails. Quoting Wikipedia: "Sender Policy Framework is an email authentication method designed to detect forging sender addresses during the delivery of the email.". An SPF record basically tells which servers/services should be allowed to send emails on behalf of a domain name.
If your domain has an SPF record and an unauthorized server tries to send an email from an email address using your domain name, that email will get a bad score from the recipient service anti-spam and will likely be either rejected or classified as SPAM. On the other hand if an email is sent from an authorized server, it gets a good score and a lesser chance of being seen as SPAM.
What's a DKIM record?
A DKIM record allows the recipient mail service to verify the email did originate from where it claims it did and wasn't tampered with. DKIM does so by applying an encrypted digital signature to the email which can be verified by the recipient mail service. Similarly to the SPF record, it gives the emails you send a better score and a lesser chance of being seen as SPAM, and protects you further from impersonators.
To know the right DKIM record you need to use for postale.io, please have a look at the DNS configuration guide. And if you'd like to better understand DKIM, have a look at our blog post "The DKIM Record Explained".
What's a DMARC record?
SPF and DKIM provide information to the recipient mail service on the legitimacy of an email, but you have no control on what the service does to emails failing at these tests.
DMARC solves this by allowing you to really instruct the recipient mail service what to do with suspicious emails. Not only that, but DMARC also makes SPF and DKIM stricter, preventing spoofing of what's called the "From" header field. Finally, DMARC provides daily reports of sending attempts made with your domain email addresses, and their outcome.
We recommend the use of DMARC along with SPF and DKIM. The combination of those three mechanisms ensures the best possible protection against abusers, thus preserving your brand and improving your domain emails deliverability.
Are SPF, DKIM, and DMARC records required?
Technically, they're not. Only the MX record is required. But SPF, DKIM, and DMARC are strongly recommended, as without them the emails you send have a much higher chance of being considered as SPAM. If you set those records, it's very unlikely than any (legitimate) email you send land in the SPAM folders of your recipients. To know the correct records you need to use our services, please have a look at our DNS configuration guide.
My Sendgrid/Shopify/(any other third party service) emails don't get delivered!
If you're using a third party email service like Sendgrid, Shopify, another service or your own server to send emails from @yourdomain.com email addresses, you'll need to include that into your SPF record.
Simply add "include:some.third.party.server.com" right before "~all" in your SPF record. Like so:
"v=spf1 mx include:some.third.party.server.com include:some.other.server.net ~all"
The SPF record above includes the SPF records of some.third.party.server.com and some.other.server.net, which themselves allow some servers to send emails on behalf of your domain name (i.e. from @yourdomain.com email addresses, where yourdomain.com is your domain name). The "mx" part says the server specified in your MX record (which in your case is "mail.postale.io", our service) is also allowed.
If you're using Sendgrid, your SPF record should look like this:
"v=spf1 mx include:sendgrid.net ~all". Or see Sendgrid's documentation.
If you're using Shopify, your SPF record should look like this:
"v=spf1 mx include:shops.shopify.com ~all". Or see Shopify's documentation.
You should also avoid using "reply-to" email addresses having a different domain name than the "from" email address. This tends to raise anti-spams red flags, especially if your SPF doesn't allow the sending server to send emails from your domain name. This could mean someone is not only trying to impersonate you/your company but is also trying to get replies (i.e. it looks like a phishing attempt).
I can't get my emails to work on my Gmail/Outlook/Thunderbird/Something mail client!
Open your mail client, and find the menu/button to add an account. The interface will ask for your username (that's your full domain email address) and your password. Enter them.
From there, most commonly used mail clients should be able to autoconfigure everything for you, thanks to our built-in autoconfiguration feature. If they don't autoconfigure, they'll ask you to provide some settings instead. Namely: SMTP server and port, POP or IMAP server and port, and SSL/TLS settings. All the settings you need to do that are provided on our mail client configuration guide.
Can I use my domain email address with Gmail?
Sure! Open Gmail and click on Settings > Accounts and Import > Check mail from other accounts > Add a mail account. Enter your domain email address and follow the steps.
When asked to enter your username, enter your full domain email address again (that's including the @yourdomainname.com part). Other settings you'll need are listed here. Please note that Gmail only supports POP.
You'll find a detailed guide on our blog post "How to Use Your Domain Email Address on Free Gmail", and some information from Google here.
Can I have a profile picture with my domain email address?
Yes, absolutely. However, please note that profile pictures actually depend on the email client used by your recipients.
With Gmail for instance, only people using Gmail to open your emails will see your Google account profile picture (or people using another mail client also showing up the Google profile picture). If you'd like that to happen with your domain email address as well, you have two options:
- Add your domain email address as an alternate email in your Google account (then your usual Google account profile picture will show up to Gmail users when you send from your domain email address).
- Create a new Google account with your domain email address (select the "Use my current email address instead" option) and add a profile picture to it (then that profile picture will show up to Gmail users when you send from your domain email address).
How to add a signature to my domain email address?
You can create a signature on the mail client you're using to send emails from your domain email address.
If you send from another mail client, you'll need to create a signature there instead.
How to enable push notifications on my phone/tablet?
We support push notifications/device synchronization via Exchange ActiveSync, a protocol initially developed by Microsoft but nowadays open to everyone.
How to set a custom from/sender/display name for my domain email address?
You may want to have some from/sender/display name for your domain email address, so that your recipients see that name when they get your emails. This can be set in your mail client, usually via an account setting called "name" or "display name".
In the webmail for instance you can do that from Settings > Identities > your domain email > Display Name. Please note this will only apply to emails sent from the webmail. Similarly if you set a display name in a mail client (say Gmail or Apple Mail for instance), that name will only be used when you send emails from that client.
There's just one exception to that rule. If you're using your domain email as an Exchange account (to enable push notifications), some apps don't offer a display name option. That's the case for the iOS Mail app for instance. As a fallback solution, and in that case only (an Exchange account without a custom display name), the webmail display name will be used instead, if you've set one.
How to enable autoconfiguration for mail clients (Outlook, Thunderbird, ...)?
Most mail clients can autoconfigure themselves from only your domain email address and password. To benefit from this feature your domain DNS must have two CNAME records respectively named "autoconfig" and "autodiscover", both pointing to "mail.postale.io". See the DNS guide or the DNS diagnostic tool for details.
Autoconfiguration doesn't work?
First you should know that not all mail clients support autoconfiguration. Some of the clients known to support it include: Thunderbird, Gmail, Spark, Outlook (though that one is not always reliable). If your mail client is supposed to support it, you need to configure your domain DNS to enable the feature.
If it still doesn't work, please make sure there are no other DNS records interfering. Some domain providers prefill mail related records and that can break autoconfiguration. In particular:
- delete any other "autoconfig" or "autodiscover" CNAME records,
- delete any "imap", "smtp", "pop", or "pop3" CNAME records,
- delete any TXT records having their values start with "mailconf=",
- delete any _imaps._tcp SRV records,
- delete any _pop3s._tcp SRV records,
- delete any _submission._tcp SRV records,
- delete any _autodiscover._tcp SRV records,
- delete any _ldap._tcp SRV records.
Or, if you're familiar with the records listed above, you can alternatively configure them to use our service. If not, better to remove them, as they are not required.
If you're still having issues making it work with Outlook, that may be due to "AutoDetect". It's a service introduced in recent years supposed to help autoconfiguration, but currently it's not reliable and has known issues that only Microsoft can solve on their end.
How to register an account?
Simply fill the two fields form at the top of our homepage. That will create a free trial account and your first domain address in one shot.
You'll be asked to configure your domain MX record. Once that's done you'll be given access to the admin interface where you can easily manage addresses and/or upgrade your plan.
For a full guide, have a look at our blog post "How to Create a Business Email Address for Free in 3 Easy Steps".
How to change the contact email associated with my account?
At registration you provided us with an existing email address we can use to contact you if needed. For instance:
- When you registered to confirm the account creation and provide guidance for the next steps.
- When you request a password reset.
- When we detect an issue with your DNS setup.
- When your domain addresses don't work and we're helping you sorting out the issue.
Since we need a way to reach you even when your domain email addresses don't work (e.g. bad DNS setup), the contact email should be a working external address (i.e. not one created on postale.io with your account).
You can change that contact email address at any time from the Account page on the admin interface. (visible to administrators only).
How/when can I upgrade/downgrade my plan?
You can downgrade or upgrade your plan at any time, from the plan page in the admin interface. We'll automatically charge you prorated amounts for the time spent on each plan.
I just upgraded to a multi-domain plan. Can I group domains/addresses from other postale.io accounts to the upgraded one?
This will attach the domain with all of its mailboxes and aliases to the upgraded account, just as if you had created them from that account directly. You'll then be able to manage that domain and create more mailboxes and aliases for it with your upgraded capabilities.
How can I completely remove my account?
You can fully remove your postale.io account (all domains, addresses, paid subscription, ...) from the Account page on the admin interface. That page is accessible by administrators only.
Beware! This action is not reversible. Once your account is deleted, all of its data (including emails) is forever lost.
How to use white labeling (branding)?
Branding, or white labeling, allows you to customize the look of our service to show some brand other than postale.io. Branding applies per domain, giving you the ability to set up different brandings for different organizations on a single account.
This feature is often useful for companies, organizations, and resellers (web agencies, freelancers...), who are interested in using postale.io as the email provider for their employees, members, or customers.
Login to the admin interface and go to Domains > yourdomain.com > Edit branding. There you'll find instructions on how to set up access to our service from a custom domain name (like webmail.yourdomain.com), and options to set things like brand logos, brand name, support URL, and so on.
Once you're done, simply provide the custom domain URL to your users (https://webmail.yourdomain.com). The brand items you've set will show up instead of postale.io's items.
What happened to the free plan?
It got turned into the $1 base plan (with a 30 days free trial), for new registrations only.
Why? Well our free plan got very popular and it started to grow a little too fast for us to keep offering it while maintaining quality of service. Nothing is set in stone though and depending on how our capabilities evolve we may or may not offer another free plan in the future.
If you registered to a free plan when it was offered, no worries, it stays free and nothing changes for you!
Where can I create/edit/delete email addresses for my domain?
On your admin interface. Only if you are an administrator will you be able to act on other email addresses.
How to set a catch-all address for my domain?
Connect to your admin interface with an administrator address. Click on your domain then on 'Edit settings', check 'Catch-all' and choose a target address.
How to add more domains to my account?
Where can I change email settings such as automatic replies and redirections?
Can I make custom rules/filters on emails I receive (to filter SPAM for instance)?
Sure! You can easily make rules from the webmail, in Settings > Filters.
For instance you could make a rule to automatically remove all emails containing a particular text, or having a particular subject, or sent from a particular email address. Or automatically move them in say the Trash folder.
That filtering interface in the webmail is very intuitive to use and requires no knowledge. When you make a filter with it, behind the scene it writes in the Sieve script of your email address.
If you need more advanced rules, you can also direclty write in the Sieve script yourself. That's done from the admin interface, in the email address settings page, click on the 'Custom filter' button within the 'Filters' section. Since both the webmail and the admin interface write in the same Sieve script, you can interchangeably use both ways to make rules.
How long do emails stay in the Trash and Junk folders?
30 days! All emails in the Junk and Trash folders older than 30 days are automatically deleted. This is a common practice, helping you to keep your storage usage under control.
Do you support automatic aliases such as email@example.com (a.k.a sub-addressing)?
Yes! We support sub-addressing with the "+" (plus) character.
For instance if you created an email address firstname.lastname@example.org, any email sent to an address of the form email@example.com will be received by firstname.lastname@example.org as well, with tag being any word you like. You can even use multiple tags, like email@example.com.
How to export or import emails?
You can easily import or export emails from the webmail. To export emails, select the emails and click on More > Download. Emails can be exported in the Eml, Maildir, or Mbox format.
To instead import emails, click on More > Import. Supported formats for imports are Eml, Mime, and Mbox. Multiple files can be compressed into zip archives. Each file you upload must be under 100 MB, but you can upload multiple files at once (you can split a large archive into smaller ones).
This is with our webmail, but most mail clients offer similar import/export features and can be used as well.
How to migrate emails from another service?
One manual way to migrate a mailbox is to use emails exports/imports. You can use a mail client like Thunderbird to export emails from the source service into an archive. Many mail services also offer built in export features in their web interfaces.
You can then re-import the archive into your mailbox on postale.io.
Automated migration with imapsync
Another, more automated way, is to use a migration tool. We recommend imapsync. It's free, open-source, widely used, and pretty straightforward. For instance, to migrate an address firstname.lastname@example.org with password mYpAsSwOrD from Zoho to postale.io, first recreate the mailbox on our service, and then run:
imapsync --host1 imap.zoho.com --user1 email@example.com --password1 mYpAsSwOrD --host2 mail.postale.io --user2 firstname.lastname@example.org --password2 mYpAsSwOrD
If you're not familiar with the command line or don't feel like installing the software, imapsync also provides an online interface. It's very easy to use and free for migrations under 3 GB. If you use that online version, we recommend you change the mailbox password afterward, for extra safety.
By default imapsync will attempt to fully replicate all folders and emails. If you need finer control, the command line tool has many options, like copy only some folders or emails based on various criteria (size, age, ...).
After impasync has finished, you may need to close and reopen your mail client or refresh your webmail page in order to see all the changes, especially if new folders were created on the destination mailbox.
Check out our blog post "3 Easy Ways to Migrate Business Email Addresses Between Services" for more information.
What are the credentials to connect to the admin interface?
Your username is always your domain email address. For your password:
- If you are the first user registered on postale.io for your domain, you received your password by email at the contact email address you've given us during registration. If you didn't receive the email, or if you've mistyped your contact email address, please contact us.
- If you are not the first user registered on postale.io for your domain, your password has been set by the administrator who created your address. Please contact him/her to get your password.
Note that you can always change your password from your admin interface.
What are the credentials to connect to the webmail?
Help, I forgot my password!
If you're a regular (i.e. non admin) user please contact your administrator, as he/she can reset your password from his admin interface. By default the first user registered on postale.io for a given domain is an administrator. However other admins can be added later by any administrator.
I know my password but it's not working anyway!
If you're absolutely certain you're using the right credentials to login but it's not working anyway, it means an administrator has changed your password. Please contact an administrator.
Where can I change my password?
On your admin interface, in the 'My address' page if you're an admin, or in the 'Password' page otherwise. Credentials are the same as for the webmail.
How come a non administrator can access the admin interface?
If you're not an administrator, you're admin interface will only allow you to modify settings related to your own address: change your password, set an out of office automatic reply, etc.
A non administrator does not have access to any action on other addresses of the domain or on the domain settings. Only administrators have such options.
How to enable two-factor authentication (2FA)?
Want to enable 2FA on an address? Easy! Login to the admin interface, open the address page, and click on the 'Edit 2FA' button.
There you can choose between Google Authenticator or email as the second authentication method. Enter the verification code, and "voilà", 2FA is enabled on the address. You can change the method or disable 2FA at any time by going back to that 2FA settings page.
What are the supported payment methods?
At this time the only payment method we support is credit or debit cards. We'd like to add support for SEPA and ACH transfers at some point.
Do you support PayPal?
No. Adding support for PayPal would require major work and would be somewhat redundant with our current implementation based on Stripe. There are no such plans at the moment.
Are payments safe?
Yes. Safely handling payments is a whole field we don't master and don't want to tackle. Instead, we're delegating that part to Stripe, one of the major and most trusted payments processing platforms out there.
Being widely used by small and large companies accross the world, Stripe maintains high levels of safety measures, both legal and technical.
On the legal side, some notable feats are Stripe having a PCI Service Provider Level 1 Certification (the highest level of certification in the payments industry), Money Transmitter licenses, and being FDIC insured. On the technical side, Stripe forces HTTPS on all communications via HSTS, and encrypts sensitive data at rest with an AES-256 algorithm, amongst many other security measures.
Find out more from Stripe's security documentation.
Do you store credit cards information?
No. This may come as a surprise if you have subscribed to a paid plan, as you are billed automatically every month, and you may have seen your credit card being preset in the billing tab of your plan page.
We delegate payments processing to Stripe, a third party service dedicated to that purpose. When you enter your credit card information, you actually give it to Stripe, not to us. They are the ones processing payments on your card on our behalf.
We never have access to your credit card data ourselves, and never will. Stripe simply provides us with an arbitrary ID identifying your credit card on their platform, along with the last four digits of the card so that you can easily recognize it.
Stripe has to store your credit card information so that your card can be automatically charged for your subscription renewals. As a payment platform, Stripes takes security of your payment data very seriously, with for instance AES-256 encryption at rest. Find out more about Stripe's safety here.
When you delete your postale.io account, your Stripe data is also deleted, including credit card(s) data.
How to change the credit card used to pay my plan?
Go to the billing tab of your plan page, and click on the Edit credit card button. The new card will be used for all future invoices.
How to change the billing information shown on my invoices?
After upgrading to a paid plan, you have the option to set some billing information that appears on your invoices:
- Email (invoices are sent to that address).
- Name (e.g. first and last names, company name, ...).
- Tax ID (e.g. VAT number, EIN number, ...).
To set these, go to the billing tab of your plan page, and click on the Edit button under the Billing information section.
Changes apply to all past and future invoices, with the exception of the tax ID which only applies to future invoices. By default, only the billing email address is set (to the one from which you first upgraded).
When am I billed?
When you subscribe for the first time, you are instantly billed for the first month. You are then billed every month on the same day for the subscription renewal. For instance if you subscribe on February 15, you'll be billed on the 15th every month.
If you downgrade back to the free trial before the end of a billing period, you are not refunded for the remaining part of the month. However a subsequent re-upgrade to the same plan won't trigger any additional charge, as you have already paid for the month. A re-upgrade to another plan will also take into account the amount already paid.
How to stop being billed?
Either downgrade back to the free trial, or delete your postale.io account.
How am I billed after a plan downgrade or upgrade?
Your next renewal invoice will be updated to the prorata of the time spent on each plan.
For instance, let's say you subscribed to Premium at $5/month on March 1st, and you upgrade to Premium Plus Small at $10/month on March 15. On March 1st you were billed $5. Your next invoice (on April 1st) will look something like this:
- 50% of paid but unused time spent on Premium in March (-$2.5).
- 50% of unpaid but used time spent on Premium Plus Small in March (+$5).
- +$10 for the coming month of April under Premium Plus Small.
- Totaling in a charge of $12.5.
Similarly, when you downgrade to a lower cost plan any overpaid amount is considered as credit and will be deduced from your next invoice(s).
What happens if a renewal payment fails or if I stop paying?
Every month your credit card is automatically charged for your plan renewal. At some point a payment may fail for any reason (insufficient funds, card is expired, ...).
If that happens you'll be notified of the failure via email. The payment will be retried automatically a few times over several weeks, during which your plan stays active as usual, giving you time to take corrective action, like changing the credit card.After all retries have failed, your plan will be deactivated. This means you won't be able to send or receive emails with your domain addresses anymore. However you can still access your mailboxes and the emails already in it.
You can easily reactivate a deactivated plan at any time (or upgrade/downgrade to another plan) from the plan page. That will resume your subscription, and instantly bring your email capabilities back. Please note that the period of time during which your plan was past due but active is still due, and it will be charged when you subscribe again.
Where to find my invoices?
You can find your invoices in the billing tab of your plan page.
How to set the email address invoices are sent to?
While your invoices are always available on your plan page, they are also sent to your billing email address.
That's the email address in your billing information, which you can change however you like. By default, it is set to the email address from which you first upgraded.
How to manually pay an invoice?
Only invoices with status "open" or "uncollectible" can be paid. On your invoices list, simply click on the invoice you wish to pay. It will open a page where you can provide payment details to pay the invoice.
Manually paying an invoice is useful if a renewal payment failed and you want to make sure the invoice is paid before your plan gets deactivated.
