Mailmeteor Review

Mailmeteor is a mail merge tool: you write one email with merge fields, point it at a list of contacts, and it sends a personalized copy to each person from your own Gmail, Google Workspace or Microsoft Outlook account, so the messages appear in your Sent folder and replies come back to your normal inbox. You can launch campaigns from the web Dashboard, a Gmail extension, a Google Sheets add-on, a Google Docs add-on or an Excel add-in, and import contacts from Google Sheets, a CSV file or by pasting addresses.

On top of the basic merge, Mailmeteor adds open, click and reply tracking, scheduling, Autopilot (drip-sending a campaign through the day to a daily cap you choose), automatic follow-ups, email verification, warm-up and a deliverability hub on higher plans. Its newer AI Email Assistant for Gmail labels incoming mail, prepares draft replies written in your voice using conversation history, and offers a toolbar to fix grammar, shorten text or change tone. Mailmeteor says its Google API usage was audited by TAC Security against CASA Tier 3 requirements in November 2025.

What Mailmeteor's own pages list:

Mailmeteor suits people who want to send personal-looking emails to a list from their own inbox: teachers and school staff, recruiters, small business owners, founders doing outreach and event organisers working from a Google Sheet. The free plan is enough to try it on small sends, and Starter is cheap if you need a few thousand emails a month. Because emails go out through your own account, it is not built for newsletters to tens of thousands of subscribers.

If you need a classic newsletter with signup forms and designed templates, Mailchimp is the more natural choice. For Gmail power users who want more sending options inside Gmail, compare GMass. For multi-inbox cold outreach at scale, look at Instantly or lemlist.

Mailmeteor's Google Workspace Marketplace listing shows a 4.9-star average from about 11,600 ratings and 7M+ installs. On Trustpilot, where the profile is claimed by the company, it has a TrustScore of 4.3 from 113 reviews: 67% five-star and 13% one-star. Reviewers there praise how quickly a campaign can be set up, working inside Gmail and Sheets, tracking and a usable free tier. Complaints include emails stuck in a "retrying" status, provider daily limits that are tight for high-volume sends, Gmail-to-Yahoo messages landing in spam, and one reviewer reporting unexpected repeat charges. Mailmeteor's own pages cite a 4.9/5 rating from 11,741+ reviews across stores.
