Mailmeteor Review — Honest Pros, Cons & Pricing (2026)

Category: Gmail mail merge for personalized bulk email

Also known as: mailmeteor.

Overview

Mailmeteor is a Google Sheets-based mail merge tool — you build your prospect list in a spreadsheet, write your template in Gmail, and Mailmeteor merges them for personalized sends. It is the simplest possible cold email setup: no separate platform, no learning curve, just Gmail and Google Sheets. The free tier allows 50 emails/day, which is enough for founders testing cold email before investing in dedicated tools. The limitation is Gmail itself — sending limits, no warmup, no inbox rotation, no sequence automation beyond basic follow-ups.

Pricing

Free: 50 emails/day. Premium: $9.99/month (up to 1,500 emails/day). Pro: $24.99/month. Business: $49.99/month.
