Is Email Tracker, Email Tracking w/ AI - Mailtag safe?
Mailtag records sent Gmail message metadata and plaintext email body to app.mailtag.io after sending.
When tracking is enabled in Gmail, Mailtag registers a send handler that posts the sent message subject, body text, recipients, tracked links, Gmail message ID, thread ID, and optional ping sequence ID to app.mailtag.io/api/v1/emails. This happens after a message is sent from Gmail and uses the extension's configured Mailtag API endpoint.
