Setting up a simple email alias to forward to 15 people

Tags: email mailgun

Short question:

Is there a way to reliably deliver emails using mailgun routes without getting this error message:

Failed: [email protected][email protected] 'Re: Sample Subject Line' Server response: 550 550 5.7.1 Unauthenticated email from is not accepted due to domain's 5.7.1 DMARC policy. Please contact administrator of domain if 5.7.1 this was a legitimate mail. Please visit 5.7.1 to learn about DMARC 5.7.1 initiative. pw18si13572314vdb.85 - gsmtp

I like using mailgun routes because it meets my needs perfectly... but it seems that I can't reliably deliver mail to multiple recipients this way.

Long Story

I'm trying to find a service that will allow me to

  1. create an email alias, [email protected]
  2. Send emails to [email protected] and have that single email delivered to 10-20 people with me as the sender and [email protected] in the to field (so "reply" goes to the sender and "reply-all" goes to everyone)

Mailgun routes fit this perfectly

I read their API docs and implemented a solution to read from our group database and make web calls to update my routes. Everything is great.

Everything worked great until I started getting the DMARC messages. Is there a way to avoid this? We're a small group (but dynamic) group and we'd like to make sending emails easy.



Mailgun is now providing mailing list support, so you only need to create a new mailing list [email protected], add members to it, and then each members can discuss by sending an email to [email protected].
