One-Click Unsubscribe adds a mandatory, standardised unsubscribe option to the header of your mass emails, separate from any custom unsubscribe link you have in the email body.
Why this exists
Google and Yahoo now require bulk senders to provide a one-click unsubscribe mechanism using the List-Unsubscribe and List-Unsubscribe-Post email headers, rather than relying solely on a link buried in the email body. This is part of their wider bulk sender requirements introduced to improve deliverability and reduce spam, and Zoho Campaigns implements this at the header level to keep your sends compliant.
The unsubscribe journey
When a contact clicks Unsubscribe, either the header-level option or a link in your content, they're shown a confirmation screen where they can confirm unsubscribing from that specific list, manage their subscriptions across lists, or unsubscribe from every list in your organisation entirely.
A known trade-off: Because the one-click header option is now often more prominent and immediate than a custom unsubscribe link buried at the bottom of an email, some senders have found their custom unsubscribe flow, such as a form asking for an unsubscribe reason, gets used far less often than before, since recipients tend to use whichever option is quickest. If capturing unsubscribe reasons matters to your business, it's worth reviewing whether your insight into why people unsubscribe has dropped since this header requirement became mandatory, and considering a follow-up survey or win-back campaign instead of relying solely on the unsubscribe flow itself.
