For existing Gmail users looking to automate and blast mass email campaigns without ruining their platform or their bank account, G Mass is an upgrade solution. It will never replace one’s own CRMs or marketing automation platforms, perhaps, but as a niche outreach and relationship-building tool, it gets the job done—fully and effectively.

Should You Use GMass?

G Mass is an excellent and inexpensive email marketing tool for Gmail senders who must send cold emails, newsletters, or auto-follow-up emails directly from Gmail itself. For the limitation of a few (such as Gmail sending limitations), simplicity, automation, and tracking features, it is an excellent go-to application for marketers and salespersons.
