So far I can think of 2 (viable) types of safeguards against this:

#### 1) Send follow-up email

@tobiaseigen’s solution of sending a follow-up email. In addition to what he already described, the follow-up email should only be send if the unsubscription happened when a user was not logged in. I hope there’s a way to differentiate between the two.

I think we’re talking about an edge case scenario here, so I strongly prefer the above solution. I’ll provide an optional one for good measure though.

#### 2) Unsubscribe by email

If you’re not logged in when trying to unsubscribe, you will land on a Discourse page that says something like:

`"You're not logged in. If you want to unsubscribe from {topic} / {category}, either [log in]() to change your notifications or <a href="mailto:unsubscribe@{forumdomain}?Subject=Unsubscribe me from {topic} / {category}" target="_top">click here to unsubscribe by e-mail</a>`

Many mailing lists let users unsubscribe this way, although usually it’s as simple as unsubscribing from the entire mailing list and that’s that, as opposed to the more granular topics & categories.
