Do You Commit These Seven Deadly Newsletter Sins? Part I

The Unsubscribe Trap

Every email marketer knows that a newsletter’s success depends on its ability to keep the right people on the list. When you send a message that people don’t want to see, you risk a spike in complaints, a drop in deliverability, and damage to your brand. That’s why the unsubscribe process should be seamless, transparent, and fully functional.

In practice, a functional unsubscribe link means a single click that lands you on a confirmation page, followed by an automatic removal from the mailing list. There should be no requirement for the reader to search for an email address, call a support line, or navigate a complex form. If the link fails or takes the reader to a page that does not reflect the requested action, you are effectively ignoring their request. In the worst case, a broken link forces readers to write an email or call, which is an extra friction point that can ruin your reputation.

In my own inbox, I once received a link that read http://www.companyname.com/unsubscribe.php?paul@domain.com.

It’s a small coding error with a big impact on user trust.

Even when the link works technically, you still need to consider the experience. If the confirmation page is cluttered with advertisements or offers that pressure the reader into staying, you are violating the basic principle of “unsubscribe for good.” The page should simply say “You have been unsubscribed.” If you want to offer a survey or alternative subscription options, place those as optional links, not a mandatory part of the flow.

Beyond the mechanical side, you should provide an accessible point of contact for subscribers who run into issues. A dedicated support email, such as
