10 Best Mail Merge for Gmail Tools in 2026

Sending the same email to 200 people by hand burns an afternoon. The right tool for mail merge for Gmail does it in minutes and still greets everyone by name.

Here are ten options to compare in 2026.

What to look for in mail merge for Gmail

Check the data source (Google Sheet, contacts, CSV or CRM), per-recipient tracking, follow-ups, daily limits and price per user. Gmail caps sending at 500 emails per day, or 2,000 on Google Workspace. Google lists a separate 1,500 per day cap for mail merge. Any tool for mail merge for Gmail that sends through your account follows these limits.
