What is Gmass?
GMass is a Gmail extension built for cold outreach and email marketing campaigns. It connects with Google Sheets to personalize messages at scale. Teams use it to bypass standard Gmail sending limits while tracking results.
GMass converts a standard Gmail account into a platform capable of sending high-volume email campaigns. Users build recipient lists directly from Google Sheets, then compose and send personalized messages from the familiar Gmail interface. The tool handles automated follow-up sequences based on whether recipients opened or replied to earlier messages. Built-in list verification helps reduce bounce rates and avoid spam filters.
