Some marketers go for quantity over quality in terms of their email lists, but that’s not a sound practice. If you have a high number of subscribers but low engagement, your email list isn’t working for you as well as it could.
A prominently displayed link to unsubscribe in the header shows confidence in the quality of your messaging. It also provides a way to reduce the amount of subscribers that don’t actively engage with your content.
Important to note: Since February 2024, Gmail and Yahoo! sender requirements ask that all email marketers use list-unsubscribe headers if they send mail to Gmail or Yahoo! users. Luckily, Brevo does this already so if you're a Brevo client there's no need to worry.
How does a list-unsubscribe header work?

There are two methods for implementing a list-unsubscribe header: Mailto and http (or URL). To make it easier to remember, mailto is the email-based method, and http is web-based.
Mailto
This is the most frequently used method for generating a list-unsubscribe header. Mailto sends an email with an unsubscribe request on behalf of the unsubscribing party.

Bear in mind that you must monitor the inbox dedicated to unsubscribes and manually remove email addresses from your mailing list when emails arrive.
Http
The http (or URL) method sends users to a landing page where they’re asked to confirm their unsubscribe request. To use this method, you have to set up a dedicated landing page and link it to your ESP, asking it to embed it into the email header.
Both https:// and https:// URLs can be used in the http method. When building your landing page, ensure that users don’t need to enter any credentials or select checkboxes in order to complete their unsubscription. The goal is to make the process as simple and painless as possible for the end users.
