Unsubscribe compliance covers the legal and provider requirements for letting recipients opt out: a visible link, one-click List-Unsubscribe headers (RFC 8058), and processing within a defined window.
What is one-click unsubscribe?
An RFC 8058 header pair that lets the mailbox provider send a POST to your endpoint when a user clicks Unsubscribe in the client, with no landing page.
Why does email unsubscribe compliance matter for deliverability?
Gmail and Yahoo require one-click unsubscribe for bulk senders, and every anti-spam law requires a working opt-out. Easy opt-out also lowers complaints.
What is the first step to get started with email unsubscribe compliance?
Include a visible unsubscribe link in every marketing message.
What is the most common email unsubscribe compliance mistake?
Unsubscribe pages that ask 'are you sure' with a hidden confirm button.
