What is GMass?
GMass installs as a Gmail extension, enabling merges from Sheets, automated follow-ups, and reporting familiar to operators allergic to leaving Google tabs. It competes with Instantly-class vendors indirectly - ideal volumes skew smaller or founder-led. Agencies managing dozens of mailboxes often graduate to Smartlead, but GMass remains sticky for consultants running thoughtful outreach from one inbox. Deliverability discipline still applies: isolate domains, verify lists, and respect ramp schedules.
