Make unsubscribing easy
The process of unsubscribing from an email list should be as straightforward as the process of subscribing, if not easier. Introducing unnecessary steps is a form of the roach motel dark pattern, where entry is simple, but exit is needlessly complicated.[1]
It's important to refrain from requiring users to log in or complete lengthy surveys as a prerequisite for unsubscribing. Instead, allow them to leave without hurdles. This not only respects their wishes but also creates a more positive experience. Should they ever wish to return, this approach leaves the door open for them.
