Members of the Zephyr Community,
Since the transition to Groups.io for mail lists, we have received a few questions regarding receipt of duplicate emails when you are sending into the list(s).
Please see below for instructions on how to turn off duplicate emails.
I Am On Gmail And I Don't Like Getting Copies Of My Messages
To turn off duplicate emails, log into your account. Then look for the dropdown in the top right corner of the page, which will be either your name or email address. Click that and then click Account. From your Account page, click the Preferences sidebar tab. Look for the 'I always want copies of my own messages' checkbox and uncheck that. Then click the Update Preferences button.
