If you’ve been using GMass for your mail merge campaigns in Gmail, you can now easily add email addresses to your account’s Unsubscribe List.
As a reminder, any email addresses on your Unsubscribe List will be suppressed from your GMass campaigns — that means they will be eliminated from any campaign you send with the GMass button. Additionally, if you’re a G Suite user and you’ve enabled Global Unsubscribes, you can also use this feature to suppress email addresses across all other GMass accounts of the same domain.
To add email addresses to your Unsubscribe List:
1. Launch a regular Gmail Compose Window.
2. Set the To field to email@example.com.
3. Type anything you like in the Subject Line, so long as it’s not blank.
4. Paste in a list of email addresses to unsubscribe as the body of the message, with each email address on one line.
5. Click the GMass main button.
Important: Be sure to hit the red GMass button, and not the regular Gmail Send button. Hitting the regular Send button won’t accomplish anything.
You can use this method to unsubscribe thousands of email addresses at once. For example, if you’re switching from a traditional email service provider like MailChimp over to GMass, you may want to take all of your unsubscribe addresses from MailChimp and import them into GMass.
To remove email addresses from your Unsubscribe List:
If you’ve accidentally unsubscribed yourself, or if you a particular email address has unsubscribed but now wants back on your email list, you can remove an address from your Unsubscribe List. Follow the same procedure as above, but set the To field to firstname.lastname@example.org.
Need to unsubscribe an entire domain?
You can also unsubscribe an entire domain. Follow the same instructions as above, but place domains on each line rather than email addresses. You can also have a combination of email addresses and domains that you unsubscribe all in one shot. More information on unsubscribing domains.
