Is Gmail AI Email Assistant - Mailmeteor safe?

Clean risk

Mailmeteor sends Gmail campaign content and email drafts to its own servers to power bulk sending, tracking, and AI writing features.

The extension injects into Gmail and transmits campaign data — including email templates, recipient lists, and scheduling options — to Mailmeteor's Firebase Cloud Functions. When users send campaigns with tracking enabled, recipient opens and clicks are reported back via pixels hosted on appspot.com. The AI email writer feature reads compose-window content and sends it to a dedicated Cloud Function to generate or refine email text.
