The easy, powerful way to reach and engage your supporters

Send personalized mass emails and automated follow-ups from right inside Gmail, no complex software required

Email is a crucial element of any modern political campaign — from raising money to communicating with supporters about events to getting people out to vote.

But… many of the email options out there for political campaigns are costly and require learning complex software.

Whether you’re using Mailchimp, Campaign Monitor, or another solution… want to send an email just to a certain segment of supporters and automatically follow up if they don’t respond? Settle in for a long night of figuring that out.

That’s why we created GMass. We set out to make a simple, affordable option for sending political emails.

With GMass, you can send a personalized, individual message to every supporter on your list from right inside your Gmail (or Google Workspace) account.

If you know how to send an email, you’ll know how to send a mass email.
