This honestly doesn't seem like a big deal to me. Maybe I'm naive, but email addresses aren't really private these days, it was limited to only fellow members of your workspace, and they were up front about the seemingly honest mistake. I've personally made worse mistakes.

If it was a workspace for your company, no it is not a big deal but there are plenty of Slack communities around topics where some ppl are anonymous.

In 2022 if you enter your email into any service you should basically expect it to be public information at some point. It’s just a matter of time until something happens and it gets leaked.

The big issue with a breach like this isn't the email itself, but the association of the email with the service.

For example, the Ashley Madison breach.
