Mailmeteor is a Gmail mail merge and email marketing platform serving Google Workspace users with in-Gmail mail merge, tracking, and campaign automation without leaving the Gmail interface. The unsubscribe mechanism uses the {{unsubscribe}} merge tag placed in Gmail campaign templates, and Mailmeteor emits RFC 8058 headers automatically for authenticated sending domains. Suppression is tracked at the contact level per Google Workspace account. This guide covers the tag, the Gmail-native model, and how to verify the setup end to end.

{{unsubscribe}}For custom HTML templates, wrap the tag in an anchor to render a proper hyperlink in the delivered email:

Yes, automatic for authenticated sending domains The recipient's mailbox provider (Gmail, Yahoo) uses the List-Unsubscribe-Post header to expose the native one-click button on the message. Requires domain authentication with DKIM and DMARC.
Mailmeteor Gmail-native design means sends flow through the users own Gmail account subject to Google Workspace sending limits (2000 emails per day for Workspace, 500 for personal Gmail). Sender reputation ties to the Gmail account not a shared ESP pool, so authentication (SPF, DKIM, DMARC) on the sending domain matters for RFC 8058 compliance. Google February 2024 bulk sender requirements apply directly to Gmail sends.
