To create a group email in Gmail, start by creating a label and selecting contacts for the group, then add those contacts to the label. To send a group email, compose a new email and start typing the name of your email group in the To field, which will automatically populate every recipient's email address. You can also use groups/labels to create Google email lists, perform contact-based actions en masse, and automate repetitive tasks with Zapier's Gmail automation. This feature saves time, cuts out menial recurring tasks, encourages teamwork, and helps ensure you never exclude anyone from an email.
