The mailo._domainkey is too long to write as a txt record on AWS Route 53. Bad experience in setting up.

DKIM register need v parameter for version record. Some server register this needed like a fail in DKIM verification. For us, v=DKIM1; works!

I love using my Yubikey, as it is a simple easy way to use 2FA. Please implement it in mailgun too!

Will be really helpfull.
I am thinking to switch to sendgrid because.
Mautic go on spam folder with your SMTP credential

We are using Mailgun for our WooCommerce webshops. When a customer orders with a non-existing mailadres we would normally receive a bounce messaging in our inbox (postmaster: delivery failed). With Mailgun we do not receive this message and therefore we are not aware that the customer filled in an invalid mail address.

Feature request:
A checkbox/setting to add a logline to the WooCommerce order log when a delivery gives a failed error (through webhooks? https://www.mailgun.com/blog/a-guide-to-using-mailguns-webhooks)

Add the ability to create/edit/delete Routes in Mailgun via Zapier.

I would like Zapier to create a client friendly email route of ClientX@mycompany.com in Mailgun and forward any inbound emails to 123xyz@basecamp.com, a randomly generated and long email address that's unique for each Basecamp project.

This will save a lot of time when setting up new client accounts, rather than configuring the Route manually. I'm sure that there are hundreds of other uses for making Routes accessible via Zapier as well.

Would love to get a Mailgun integration with Segment.io so we can easily pass data and reporting analytics back and forth.

It would be neat if Mailgun could go and READ an existing domain's SPF record (like cloudflare does) and returns a COMPLETE, accurate new SPF record.

No big deal, but helpful for us less brainy clients!

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.

Allow Mailgun account email to send emails to mailing lists from Outlook without having to change the outgoing servers. This would be a step between needing to be authenticated (Read Only) and Allowing people in the mailing lists to post things.

This way the owner of the mailgun account can send emails from Outlook to their mailing lists, but no one else would be able to do this.

It would be nice if mailgun had an official slack app , so that we can automatically post delivery or perhaps analytics based details to certain channels for I.T and Ops teams to review , that do not have access to the Dashboards or the mailgun admin website.

The current webhook service area does not work with slack's interpretation of what a webhook should post (in terms of tokens) and is not useful as a result.

I would like to be able to add Google Analytics tags to links in my emails so i can combine my email campaign data with my campaign from other mediums

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.

The current URLs used for tracking link clicks are quite long. Offering a way to shorten them via Bit.ly or perhaps an custom shortened URL would be helpful.

I'd love to see a WordPress plugin that would allow control of settings and show reporting while allowing the site to use Mailgun to send emails from it's domain.

Allowing a "Reply to" address that is different from the "From" would GREATLY expand the power of the Zapier integration by allowing users of an application to follow the Truthful Routing clause of the CAN-SPAM while being able to receive replies.

Please add the possibility to forward feedback loop emails so that we can use other tools to analyse them in more detail then Mailgun provides...

Universal links in iOS 9 make it possible for our links to open directly in our app. Unfortunately redirects break this behavior, so Mailgun's click tracking breaks our universal links.

A simple workaround would be to allow us to set an arbitrary CNAME. I could then point that CNAME at a CloudFront distribution. That way we could serve an apple-app-site-association file and redirect all other requests to mailgun.

We could then intercept the click tracking links in the app, and fetch the click tracking link to record the click and get the redirect target.
