How List-Unsubscribe Enhances Email Deliverability

Overview

In this guide, we'll explore the concept of the list-unsubscribe header, its benefits for email deliverability, and address common questions about its functionality.

What is the List-Unsubscribe Header?

The list-unsubscribe header is an additional 'unsubscribe' link provided by popular email services like Gmail and Outlook. This feature allows recipients to easily remove themselves from your mailing list without needing to find the unsubscribe link within the email body.

Benefits for Email Deliverability

Utilizing the list-unsubscribe header is considered a best practice for maintaining high email deliverability. It offers subscribers a straightforward way to opt-out, reducing the likelihood of them marking your emails as spam. This proactive approach helps in preserving your sending reputation by minimizing complaints.

Can the List-Unsubscribe Header be Disabled?

No, the list-unsubscribe header cannot be disabled. It is a standard requirement across the industry, ensuring consistent functionality across email platforms.

Why Might the Unsubscribe Option Not Appear?

The unsubscribe option in the email header is typically available for senders with a high reputation. This feature is not universally available yet, as it is dependent on the sender's trustworthiness. Stack is committed to encouraging more senders to adopt this auto-unsubscribe feature to enhance user experience.

The option will not appear in emails from suspected spammers, as there is no guarantee they will honor unsubscribe requests. Over time, we aim to expand this functionality to include more trusted senders, allowing users to manage their subscriptions more effectively.
