Gmail, how to forward email to group using a filter

Not directly, no.

You need to set up a mailing list, such as on Google Groups. (Really it could be any of a number of services. The key is that there is a single email address to use that will send all messages sent to it on to member email addresses.)

However, there’s a bit of setup involved and your syndicate members will need to do a little work as well.

This is how I’d do it:

  1. Create a Google Group. It will have an email address like
  2. In Gmail Settings, under “Forwarding and POP/IMAP”, use the “Add a forwarding address” and add the email address for your Google Group
  3. A confirmation email will be sent to that address and you need to follow the directions therein so that you can auto-forward to that address. Since you’re the admin of the Google Group you should be able to see it in the web interface. (It’ll probably be emailed to you anyway.)
  4. Follow the instructions to confirm that you own the address. Now you can use the address in a Gmail filter
  5. Create a Gmail filter that acts on the messages you want to auto-forward. As its action, forward the messages to the address you just confirmed
  6. Once you confirm that the messages are acted on appropriately, use Google Groups to invite the people you want to join. (If memory serves, you can’t add them directly. You have to invite them. It’s a spam prevention measure.)

That should be it. You don’t need to use Google Groups, obviously. There are other mailing lists/forwaring services out there. (Personally, I’d probably use an autoforward mailbox provided by my ISP. No need for invites there; I can add the addresses that I want.) The key is that you need to be able to prove to Google that the mailbox to which you want to forward messages is under your control.

1You may need to add to the group so that the confirmation code gets sent to the group. After confirmation, you can remove it. (h/t to Emil.)
