The primary manifest — the file an agent reads to learn what this artifact does.
Use the mailbridge MCP read-receipt tools to track whether sent emails have been opened.
Mailbridge uses read-receipt headers (RFC 8098 / MDN), not tracking pixels. When you send with a receipt requested, the recipient's email app may prompt them to confirm they read it. If they agree, their app emails back a machine-readable confirmation, which Mailbridge detects by scanning the inbox.
Always set expectations clearly — never imply this is reliable like a messaging "read" tick:
When the user wants to track an email, pass request_receipt: true to send_email or reply_to_email (see the send-email skill). Confirm with the honesty caveat above.
When the user asks whether an email was opened:
check_email_opens (optional folder, default INBOX). It scans for new confirmations, updates the local record, and returns a summary. ✅ Opened: "Subject" — by [email protected] at [time]
… Awaiting: "Subject" — sent to [email protected] on [date]To show current status without re-scanning the inbox, call list_tracked_emails.
If any tool returns "No email account connected", offer to call open_setup.
