Mailmeteor

Mailmeteor is an email outreach and mail merge platform that works directly inside Gmail, Google Sheets, Google Docs, Excel and Outlook. It lets you write one message and send personalized copies to hundreds or thousands of contacts from your own mailbox, with open, click and reply tracking in real time. More than six million people use it, and it holds a 4.9 rating from over 11,000 Google Workspace Marketplace reviews.

Its AI email assistant helps draft replies and subject lines in your tone, while follow-up automation, scheduling, reply detection and sheet automations keep campaigns moving. Deliverability is a focus: BounceShield flags invalid addresses, Autopilot throttles sending, email warm-up and verification protect sender reputation, and a Deliverability Hub monitors sender health. Gmail accounts send up to 500 emails a day and Google Workspace accounts up to 2,000.

Founded in Paris in 2018 with a privacy-first, GDPR-compliant approach, Mailmeteor is aimed at sales teams, marketers, recruiters, founders, support teams and freelancers who want affordable personalized outreach without a heavy email marketing suite.
