  1. Revert recent change regarding 400 Bad Request on non-working email addresses

    Mailgun provides an excellent service. However, a recent change was made to the API: 400 Bad Request is returned if the address is not valid.

    The validation is a deep check that is not commonly performed (in my experience), including checking the domain for a MX record and effective TLD names (using https://publicsuffix.org/list/effective_tld_names.dat).

    The issue with this is

    1) There are no clear distinction between an invalid API request and invalid content. E.g. you get a 400 bad request if a required parameter is missing and if the email address is invalid

    - Currently the documentation states: "Bad Request…

  2. Setup a Mailgun install without composer required.

    Being forced to install composer seems a bit unnecessary. I would love not needing the overhead of composer.

  3. Retrieve Rendered Message via API

    The new capability to show a rendering of the message on the dashboard is fantastic, but would be nice if we could request this via the API for display on our side.

  4. Enable MailGun Api to send email with multiple BCC email addresses only.

    It's a common scenario when you want to send an email and have a list of recipients which for business purpose needs to be in BCC.

    Currently the error which comes from the MailGun Api is "'Bad Request - 'to' parameter is missing' error."

    Here are some StackOverflow threads about this

  5. Accept attachments encoded as Base64 strings in the "/messages" API endpoint

    It might be helpful for some users if the "/messages" API endpoint would accept attachments as Base64-encoded strings, with a name and content-type described somehow.

  6. API : Add an API method to download attachment for inbound emails.

    Right now mailgun SDK provides no method to download attachment given we have the URL. Only method is to download the attachment via language specific libraries like open-uri for ruby and we have to pass parameters for authorization. It would be great if there is a pre-built method to download attachments easily

  7. API: List all stored messages

    It would be nice to have the option to list all the stored messages (excluding the deleted ones).

    Today the only way to get the list of stored messages is to get it by the events API, so there's no way to get only the non-deleted messages, or to get all the stored messages in a single request.

  8. implement a test api key

    In Mailgun you should be able to use a test api key to experiment with Mailgun's API. No mail should be sent, but webhooks should trigger normally and you should be able to generate synthetic bounces and complaints without impacting your reputation.

    This also lets the developer to setup a development environment that is similar to the production environment without the risk of sending any mails by misstake.

  9. Prevent duplicate emails to same recipient

    We had a bug on our end that sent the same message to the same recipient thousands of times—resulting in thousands of spam reports while we were oblivious until months later.

    While there are things we could do on our end to improve quality control and ops, etc., it would be amazing if Mailgun could provide a duplicate detection feature. I'm imagining saving a hash of content for sent messages, and catching any time we repeat the content to any recipient. A repeat could be prevent, or an alert sent, or both.

  10. allow cancelling an email via API

    I'd like to be able to cancel a pending email via the API. eg If we don't get a 'delivered' or 'bounced' webhook within 10 minutes, it probably means that the email was delayed in some way (throttled by receipient or some other soft bounce) and at that point we'd like to cancel the sending of that email so that we can resend through other methods without the recipient later getting a duplicate message once the message finally goes through with you.
    I'd suggest the MessageId as the key for use for cancelling since it is returned from the sending…

  13. Add an md5 hash to the attachment object in the API

    I would like to save myself from having download an attachment if I already have a matching file stored locally.

    Our organisation sends out alot of product brochure that are mostly all identical.

    Rather than download this attachment in our application, I would use the copy I have on hand. Saving alot of bandwidth/server load
