GMass

GMass is a Gmail-based email campaign tool designed to help individuals and teams send newsletters, announcements, cold email campaigns, and transactional emails from within Gmail. It is positioned to serve solopreneurs up to large organizations that rely on Gmail or Google Workspace for outreach and communication.

GMass operates by staying inside Gmail and enabling campaign creation, scheduling, and tracking without requiring users to leave their inbox. Users connect data sources such as Google Sheets to Gmail, build mail merges, and then send campaigns with features like open and click tracking, auto follow-ups, and unsubscribe handling. The process emphasizes building campaigns directly in the familiar Gmail environment for a streamlined workflow.

GMass highlights capabilities around mail merges, automation, tracking, and deliverability adjustments. It supports features like dynamic lists, multiple SMTP options, and real-time campaign controls. The platform also discusses tools to monitor sending speed, handle Gmail limits, and reroute through SMTP services to extend daily quotas. These elements collectively describe a tool aimed at scalable email outreach while remaining compliant with Google terms of service.

GMass lists plans and platform considerations, including integrations with Google Sheets, Gmail, and external SMTP providers. It also notes settings related to unsubscribes, global unsubscribes, and list management, indicating platform and integration boundaries without detailing specific pricing.
