Why should I use the List-Unsubscribe header?

It gives inbox providers a safe and standard way to handle unsubscribes, which reduces spam complaints and protects your domain reputation.

Is a mailto link enough for List-Unsubscribe?

A mailto link is better than nothing, but a one click HTTPS link plus mailto fallback gives the best user experience.

Do I still need an unsubscribe link in the body?

Yes. The header complements, not replaces, a visible unsubscribe link in the body of your email.

Provider-specific notes for Wix

Wix manages DNS for domains registered through them. You can add TXT records directly in the Wix Dashboard under Settings → Domains → DNS Records.
If your domain uses external DNS, Wix cannot auto-publish DKIM. You must copy the records Wix provides and add them in your registrar's DNS panel.

What is List-Unsubscribe?

List-Unsubscribe is a message header that gives inboxes a safe, machine readable way to unsubscribe. Gmail and Outlook often show a clear unsubscribe link when it is present and valid, which reduces spam complaints and protects your sender reputation.

How to enable it in practice

In your sending platform, enable the List-Unsubscribe header or macro in templates.
Use a one click HTTPS link as the main method, with a mailto address as fallback.
Test by sending to a Gmail address and checking “Show original”.

Example headers

List-Unsubscribe: <https://yourdomain.com/u/abcd1234>, <mailto:[email protected]?subject=unsubscribe>
List-Unsubscribe-Post: List-Unsubscribe=One-Click

Common mistakes

Using a broken or redirected unsubscribe link that fails when clicked.
Only providing a mailto address without a one click URL.
Failing to apply the unsubscribe globally across lists and tools.

Pro tip: Turn on InboxGreen Monitoring to check these records daily and get alerts if something breaks.
