VERDICT

Should I use GMass?

Easiest way to send an email campaign — mail merge and mass email inside Gmail - gmass.co

Depends. Buy it if your team lives in Gmail and sends modest mail-merge or cold-outreach campaigns from Google Sheets. Skip it if you need high-volume sending, full marketing automation, or a free tier — the free plan has been discontinued.

Confidence
