Has anyone here managed to set up the email for their Ghost blog, that you hosted using Pikapods? We’re using Mailgun, but cannot get it all to work.

I’ve been trying for ages - no luck. First we’re trying to just get it to be able to send the email invite for a new staff member. won’t do that. Haven’t even got to the bulk emails yet (though I have inputted the Mailgun API key to Ghost).
