About

What is Mailmeteor

Mailmeteor sits inside Gmail and Outlook as a mail merge layer, pulling rows from Google Sheets to send individually addressed emails at scale — up to 2,000 per day on paid plans. It's built for founders and SDRs who want to run outreach campaigns without leaving their inbox or learning a separate platform. The standout capability is its built-in spam checker, which flags trigger words before you hit send — a practical guard against deliverability issues that most tools in this category skip. It also connects natively to Salesforce and HubSpot, and supports AI-assisted copy generation per recipient. Where it falls short: there's no API, so you can't wire it into automated workflows or agent pipelines — every campaign requires manual setup through the UI.

Our verdict

Vanderbuild take

Mailmeteor is a no-frills email sender for founders and SDRs who want to run personalized outreach directly from Gmail without adopting a full sales engagement platform. On the agentic readiness front, there's no API and no MCP server — this is UI-only, meaning you can't drive it from an agent or plug it into an automated orchestration layer without scraping. Free or near-free, low risk to test — the free tier covers 50 emails a day and paid plans start around $5/month. The ceiling is real though: if your outreach volume grows, Gmail's own sending limits will constrain you before Mailmeteor's features do, and there's no multichannel capability beyond email.
