While not always legally mandated for purely transactional emails, including unsubscribe links is generally considered a best practice, particularly in the context of recent email authentication changes and evolving user expectations shaped by Yahoo and Google updates. The main reasons are improving deliverability, reducing spam complaints, and demonstrating respect for recipient preferences. If an email contains both transactional and commercial content, unsubscribe mechanisms are legally required. Additionally, the definition of "transactional" must be carefully considered, as many emails labeled as such do not strictly qualify and require unsubscribe links.
8 marketer opinions
While not always legally required for purely transactional emails, the consensus is that including unsubscribe links is a best practice, especially with the recent Yahoo and Google updates. Even for emails primarily conveying essential information, offering an easy opt-out reduces spam complaints, maintains a healthy sender reputation, respects recipient preferences, and improves overall deliverability. High complaint rates may necessitate unsubscribe links, even if not otherwise required. If emails contain any commercial content alongside transactional information, unsubscribe mechanisms are legally mandated.

Experts generally agree that while unsubscribe links may not be strictly necessary for *purely* transactional emails, including them is often a good practice, especially in light of recent email authentication changes and evolving user expectations. Unsolicited transactional emails, like password resets, can be mistaken for phishing attempts. Regulations vary by region, such as Canada requiring unsubscribe links in transactional emails. Accurately classifying emails as transactional is crucial, as many emails labeled as such may not qualify. Easy unsubscribe options are beneficial for reducing spam complaints and maintaining a positive sender reputation, and may be legally required if the email has any commercial component.
