I’m not talking about Heroku’s region. I’m talking about that reading Mailgun docs it seems that when you add domain to Mailgun you need to select is that domain for US or EU.

Hey all,
@phcurado @wanton7 @derek-zhou @sfusato first, thank you all for trying to help. I’m a lone developer trying to get my side project running and it’s extremely useful to have someone to talk to about the problems that I run into along the way.
I reached out to Mailgun’s support team and I’ve finally fixed the problem. It turns out that I whitelisted my own IP which meant that it was rejecting all other IPs. After removing my IP from the white-list it finally works!
Thank you all again!
