There is currently not any support for credit card payments that have an extra factor of authentication (specifically VISA 3D Secure Authentication, in this case).
Stripe provides documentation on how to add this support within their integration: https://stripe.com/docs/payments/3d-secure

I'm sending mails through mailgun.com via STMP and I add "List-Unsubscribe" headers to my emails prviding unsubscribe-email and -url (where appropriate).

As these headers (email and url List-Unsubscribe) are not included in the DKIM or DomainKey signatures, they are ignored by some mail services ...e.g. Gmail. :-(

Please include the provided List-Unsubscribe (and possibly other already existing) headers in the DKIM- and DomainKey signatues or provide an option to define which headers should be included. => X-Mailgun-Include-In-Signature header

Thanx!

I have some software nearing completion and it will be distributed to customers on a subscription basis. A few customers would also like the host the software themselves. Maintaining multiple API Keys that link to the one account allows us to control our customer's usage should the subscription expire and prevent us from giving them our API key.

Add Idempotency-Key to request ala Stripe's API. https://stripe.com/docs/api?lang=curl#idempotent_requests

You should start sending an email alert or notification when a domain is disabled by your outbound spam filter

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.

t is important to us as a customer to be able to edit our SMTP credentials. Our system is limited to a password character max of 8 characters. I respect you security effort in generating a very long password but, this will not work for us. Please pass this on to those who need to know. Thank you so much for your consideration is this matter.

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

If no text portion of an email is submitted, automatically make one from the html portion. This should help with deliverability. The parse incoming seems to do this now according to the documentation so you may already have routines to do this.

It'd be oh-so-useful to use MailGun like http://mailcatcher.me/, http://papercut.codeplex.com/ or http://mailtrap.io/ when developing software - you've got most of the infrastructure in-place already!

Every time I login, it requires a 2-factor auth code.
Can we set it so it doesn't ask us the code each and every time we login? I login daily and it drives me insane!
Instead, it could ask us for it once every 30 days or only when signing in on a new browser?

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.

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.

Hi there.

When designing HTML emails, having to use inline styles (style="xxxx") instead of CSS classes is a right old pain.

There are tools and libraries that can take a HTML document, and automatically 'inline' the CSS styles. E.g. http://beaker.mailchimp.com/inline-css

It would be AWESOME if there was an option to apply this transformation to a HTML email before it gets sent....

Allow logic to be included in templates to make decisions based on template variable data.

Example:
{% if %recipient.name% %}
Hi, %recipient.name%!
{% else %}
Hi!
{% endif %}

I would love the ability to hook up my Mailgun account to a service like Papertrail (https://papertrailapp.com) so I can get access to emails more than 30 days old. We've had half a dozen cases in the last few weeks where we've needed to see if a receipt email was received, but since it was more than 30 days ago, we're out of luck.

At this time Mailgun does not provide support for sending user specific attachments in batch mailing. Please add the support for that. In case of sending thousands of emails, we have to call the mailgun APIs thousands of times which does not look a valid approach. And we can't send URL of the attachments in the emails because the attachments files are stored temporarily on the server and it's confidential.

Adding this feature will be very helpful.

Thanks a lot.
