Overview
GMass
GMass turns your regular Gmail or Google Workspace account into a full-featured email marketing platform. You can send mass emails, create complex mail merges using Google Sheets data, and schedule automated follow-up sequences that stop once a recipient replies. It lives entirely inside your Gmail interface, so you don't have to learn a new dashboard or export your contacts to external software.
You can use it to bypass Gmail's sending limits by connecting to external SMTP services or stay within standard limits for smaller outreach. It solves the problem of low engagement by making every mass email look like a personal, one-on-one message. Whether you are a recruiter, salesperson, or non-profit organizer, you can manage your entire outreach strategy without ever leaving your inbox.

You can recover lost revenue with abandoned cart sequences, welcome new subscribers, and reward your best customers with automated loyalty workflows. The platform is designed for growing online stores that need sophisticated automation without the complexity of enterprise-level tools. You get access to pre-built automation templates and a drag-and-drop editor that makes creating professional campaigns fast and intuitive.
