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.

Beyond simple tracking, you can schedule meetings instantly with one-click calendar inserts and set up automated follow-ups that stop once a prospect replies. It is built primarily for sales, account management, and recruiting teams who live in their inboxes and need to scale their outreach while maintaining a personal touch. By syncing all activity directly to your CRM, you ensure your data stays accurate without manual entry.
