  1. RFC 2821 Compliance

    MAIL-FROM addresses should be RFC 2821 compliant, where the local-part of the address is a maximum of 64 characters. Presently this is not the case, and MAIL-FROM addresses can be very long depending on the original local-part, due to the bounce+id being added.

    Example: bounce+fe4961.7d6c90-thisisareallylonglocalpartaddressintheoriginalemail=hostname.com@mg.senderdomain.com

    The local-part of this address is 85 characters long, and is not RFC compliant, which causes mail to be rejected from MTA's which enforce this 64 character limit.

  2. Add a Date Range Filter on the Analytics Page

    Currently, we are only able to filter information on the "Analytics" page by day. It would be very beneficial to be able to filter by a date range for our data under the analytics page in a similar fashion to how the "Reporting" filter works (30, 60, 90, or custom day range).

  3. Billing: provide proper invoices

    Currently, mailgun only provides an overview on purchased items and its price. However, this does not meet requirements for financial authorities, for instance in Austria. A proper invoice must contain:
    - name and address of mailgun
    - VAT of mailgun
    - name and address of customer
    - VAT of customer (if total exceeds a limit)
    - explicitly account tax, or hint for reverse charge
    - sequential number of invoice

    Hi all,

    Thanks for your patience here! Since moving to a new billing system at the beginning of this year, I think we’re well on our way to meet the majority of the listed requirements. Our invoices now include:

    • Full name and address of the supplier and customer (as long as customer address is specified in your account under account details – Billing Address)
    VAT number of the customer (as long as this is specified in your account under account details – VAT number)
    • A unique, sequential number

    I’ll need to work with the team on getting the Mailgun VAT number and tax/VAT info, as well as zero VAT support.

  4. Allow to purchase more recipients in sandbox domain.

    I would like to use Mailgun from our test environment where I would send all mails to Mailgun (SMTP/API) but configure in the domain (sandbox has add recipient) the mail adresses that should realy be sent. The 5 recepients limit in Sandbox is not enough for our needs. A way to purchase more recipients and to enforce authorized recipients only from a sandbox domain.

  5. Allow CNAME chaining for tracking opens, clicks.

    Currently my app (email.mydomain.com) CNAME is pointed to mailgun.org, but when I have my users' domains point to email.mydomain.com, it does not accept this as a chain CNAME.

    It would be nice to validate this so it can be whitelabel.

  6. fully support non-ascii characters when attaching filenames

    Currently mailgun API does not officially support non-ascii characters in filename attachments. There are workarounds but it would be nice if it was supported natively.

  7. Apply substitutions to BCC of Bulk Email

    When doing Bulk Email with recipient variable substitutions, those substitutions are not applied to what is sent to the BCC address(es), so instead of getting a copy of what was actually sent to each of the normal recipients, the BCC is just the template.

    I can imagine a variety of reasons why this might happen, but cannot come up with a reason why anyone would want it to work this way.

  8. U2F 2 Factor Auth (Yubikey)

    Implement U2F/Yubikey support for 2 factor auth.

    This will enable people who can't use their phones in the office, but can use hardware tokens, to take advantage of the 2 factor auth you just implemented.

  9. Add # of Pages to API Events

    The "paging" array in the events API should show the total number of results and the number of pages so you can iterate through multiple pages easily, knowing exactly where you are in the pagination. The current version of the API shows no count so you have to paginate through the results blindly. Not ideal and impossible to mitigate performance issues when handling many pages of results.

  10. Add event id to Webhook events

    Hi guys. We would like to support our clients without added CNAME same as the clients who have added.
    It's okay, we are getting the domain's CNAME info to check if the client's domain verified.

    But, our main issue is we can't be 100% if an event has been added to our database or hasn't.

    We have to make a unique index with the timestamp, event, messageid columns, this seems to be a bit dumb solution...

    I can understand that the webhook events are coming to us before they would arrive at your storage, but you should solve this and…

  11. Provide a way for users to resubscribe

    The %unsubscribe_url% tag can be used to create a link to the Mailgun unsubscribe page, but once a user has unsubscribed they can't resubscribe themselves later. They might have unsubscribed in error, or changed their mind, but there's no way for them to opt back in themselves.

    Ideally you'd have a "Manage my subscription" page that could be linked to via a tag like the %unsubscribe_url% tag, where a user can either unsubscribe or resubscribe themselves.

  13. The (subscribed) sender of a mailing list should also receive his own sent mail

    The (subscribed) sender of a email (to a mailgun mailing list) will not receive his own email, when he writes to a list. This is a very confusing behaviour for most of the users and it will result in countless misuses: The users will try to send their email over and over again, because they think that their email didn't get through the mail system.
    I have never seen and never used a mailing list service that behaved in this way. Googlegroups, Yahoogroups, Domeus, whatever... you always get back your own email. Furthermore, this behaviour is not mentioned in the…

  14. Order suppressions in reverse chronological order

    Currently suppression come up in random date order which is of no use and makes no useful sense.

    Suppressions in reverse chronological order would be most helpful to see the most recent items added to the suppression list so ones that are added can easily be removed. Sendgrid does this and it makes removing items from the list much easier.

  15. Limit monthly email quantities per SMTP Credential, per domain

    I would like you to add a limit on the amount of messages that can be processed per month, for individual "SMTP Credential", for a given domain.

    E.g. a domain "mydomain.com" has 3 SMTP Credentials: admin@mydomain.com, secretary@mydomain.com, and guest@mydomain.com

    I would like to be able to specify how many monthly emails a specific SMTP Credential can send: admin@mydomain.com = unlimited, secretary@mydomain.com = 10,000, guest@mydomain.com = 1,000 emails per month.

    Please add this feature.
    Thanks

  16. Enhance DMARC By Adding the Authenticated Received Chain (ARC) Protocol

    Mailgun should enhance their mail engine MTA to use the Authenticated Received Chain (ARC) protocol with all inbound and forwarded messages that go through Mailgun.

    There are 2 situations where this will help. When evaluating inbound emails and the DMARC policy of the sending domain is checked and fails or when Mailgun receives an email sent to a mailing list that, in turn, sends the message to all mailing list members.

    For both these scenarios, if a DMARC check is done and the original sending party has a policy of quarantine or reject, it is possible for these valid emails…

  17. Disable click tracking on specific links

    It would be great to add the ability to disable click tracking only for some specific links in an email.

    In know that you can disable click tracking for all links in an email, but I couldn't find anything about doing it only for a specific link.

  18. Document list of error codes, reasons, and event types that may be generated by Events

    Currently, there is no documentation detailing the set of error codes and reasons that could appear in an Event. For event types, this appears to be the only available link https://documentation.mailgun.com/en/latest/api-events.html#event-types but has some inconsistencies.

  20. role-based multi-user access restricted by domain

    We were excited to discover the multi-user capability and are even more excited for the possibility of restricting access based on role and domain.
