Questions

## Common questions, straight answers.

What does one-click unsubscribe mean in practice?

PostFrame adds List-Unsubscribe and List-Unsubscribe-Post headers, so Gmail and other clients show an Unsubscribe button beside the sender. Clicking it POSTs to PostFrame and the address is suppressed without opening a page.

Can someone unsubscribe another person?

No. Each unsubscribe link carries a signed token bound to the email it was sent in; an invalid or altered token is rejected.

Can a customer opt out of marketing but keep transactional email?

Yes. Unsubscribe groups scope an opt-out to a kind of send, so leaving the newsletter group does not stop receipts or invoices.

Do unsubscribes fire a webhook?

Yes. email.unsubscribed carries the method — one-click or link — and the source, alongside the email's ID, subject and tags.
