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.

The platform features a built-in B2B database with over 140 million contacts, allowing you to find and engage new leads directly within the tool. You can also use the AI sales assistant to draft personalized emails and respond to prospect inquiries automatically. It is built for sales teams, agencies, and recruiters who need to scale their outbound efforts while maintaining high deliverability and engagement rates.
