Last updated: February 2026

About GMass

GMass is a cold email tool that works entirely inside Gmail. It turns your Gmail account into a cold email platform with mail merge, automated follow-ups, scheduling, and campaign analytics.

The tool installs as a Chrome extension and adds campaign controls directly to the Gmail compose window. This makes it extremely easy to start sending — there is no separate platform to learn.

GMass is ideal for individuals and small teams who want to send cold emails directly from their Gmail account without the complexity of a standalone platform.
