Gmass

GMass is lightweight and unobtrusive. After you install GMass, you will notice four extra buttons within your Gmail interface. Three of these buttons are small square buttons to the right of the search field: the 'Build Email List' button, the 'Google Sheets Connect' button and the 'Follow-up Campaigns' button. When composing an email, you'll notice the main GMass button along with a settings box, next to the regular Gmail Send button. Lastly, you'll see some new Gmail Labels on the left where we store reports, like open and click reports.

Most mass email campaigns are sent as new messages, and therefore new conversations, with each recipient. The ability to send a mass email and have each individual email sent as a reply to the last conversation with each recipient creates a more familiar experience for the recipient than a new message would, because the email campaign is threaded within the conversation. If there is a recipient in your list with whom you have not had a prior conversation, then a new message will be sent.

This option is useful if you want to test GMass’s functionality but don’t want to actually send anyone emails. For example, if you want to ensure personalization is working, this option comes in handy. You can also use the 'Send Test Email' button to test personalization.

Auto follow-ups are the best thing to happen to email marketers since well...email marketing. Auto follow-ups allow you to send follow-up emails automatically to recipients of your email campaign that have not replied. The auto follow-up sends as part of the same conversation as the original message, making it appear like you're manually hitting Reply on the original sent email to ping the person you're targeting, but in reality, this is all happening automatically. If someone doesn't respond to your first email, an auto follow-up is the best way to get them to reply.

Maybe. It's up to you. Some users use GMass alongside their primary email marketing system, using GMass for lower-volume campaigns and their main system for bigger campaigns. GMass can handle campaigns of up to a few hundred thousand recipients using the SMTP connection feature. GMass is not designed to send a campaign to millions of addresses. One way GMass supplements your actual email marketing system is by making it easy to follow up with everyone that replied to a campaign sent through a traditional ESP. Assuming the replies go to your Gmail account, use GMass to search for the replies, then use the Build Email List feature.

Click Compose in Gmail. Enter a few email addresses in the To field. Put in a Subject and Message, and hit the GMass button (instead of the normal Gmail Send button).

Yes. You compose your email just as you would any other email message in Gmail. Any feature of an email that Gmail supports you can assume that GMass also supports.
