I’m trying to figure out if there’s a way to configure the reply-to header for a Mailgun mailing list. The problem I’m facing is that people keep hitting reply instead of sending messages to the intended recipient address. This creates a flood of unnecessary responses like “Thanks!” or “Count me in!” that everyone on the list receives. The whole list gets spammed with these short replies when only one person actually needs to see them. I’ve tried telling people to send responses to a specific email address but many ignore this instruction. Is there a setting in Mailgun that lets you control where replies go instead of back to the entire list?
had the same problem! I set up a dedicated email just for replies and used it as the reply-to. most clients pick it up and direct responses there, which really helps with the clutter of “me too” responses.
Here’s another approach - set up proper list hygiene using Mailgun’s unsubscribe management. When you send messages through their API, you can include custom headers for both List-Unsubscribe and Reply-To addresses at the same time. I figured this out after dealing with a community newsletter where people kept replying with vacation notices. First, configure your sending domain properly. Then use the messages API with the h:Reply-To parameter pointing to your designated address. This worked way better for me than just using dashboard settings since you get more control over each campaign.
Mailgun doesn’t allow for changing reply-to headers for mailing lists via their dashboard, but there’s a workaround. You can use the API to set custom headers. By adding a ‘Reply-To’ header that directs responses to a specific address, you can prevent replies from flooding the mailing list. I faced a similar issue with a newsletter, where replies cluttered the list. I resolved it by including a ‘Reply-To’ header in the API calls. Just be aware that this approach requires coding, as the user-friendly interface won’t suffice.
