Just wanted to bump this topic up since I’ve been playing around with the Zapier + Mailgun integration in order to send Welcome Emails and have something that works pretty well. (as long as you are comfortable dipping into HTML a bit)
I’ve written a blog post that describes how to do it step-by-step:
How to Send a Welcome Email with Ghost and Mailgun
If anyone has any issues, happy to help, just drop a reply here.
Cheers!
