What is GMass?
GMass is a mail merge and cold email tool that runs as a Chrome extension inside Gmail, letting users send personalized bulk campaigns straight from their existing inbox using Google Sheets for merge data. It adds automatic follow up sequences that stop when a recipient replies, real time open, click, reply, and bounce tracking, and a Spam Solver tool for testing deliverability before a send.
Individual plans range from Standard through Premium, which adds inbox rotation across multiple Gmail accounts, up to Professional with the highest priority support. Team plans scale by seat count for organizations sending from several accounts. GMass offers a 7 day free trial capped at 50 emails per day, with no separate free plan after that.
