I use Notion.so to create blog posts in markdown, and we're incredibly productive with this workflow! I'd like to be able to create email messages and templates using markdown, and have mailgun translate those to html. Ideally, this should be supported in the API and in the UI.

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.

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....

Please consider providing the timestamp, token and signature as http headers. Some frameworks such has JAX-RS provide the ability to validate an incoming request via interceptors. This is difficult to do with form data as it is processed later in the request.

Ideally this would be done similar to Twilio https://www.twilio.com/docs/security

Maybe an

X-Mailgun-Timestamp
X-Mailgun-Token
X-Mailgun-Signature

Based on this we could verify the request before actually decoding the form data.
