Honestly I'd rather them not send an apology email... because then I'd have two useless emails. And in the grand scheme of things, it's literally just one more email I receive during the day.
Because that would be a much bigger problem than sending an email by accident.
If I get a moment I might GDPR the info out of them but honestly loads of spammers have my email it's nbd.
e: Going by past emails someone decided to change their account's email to mine (which HBO was fine with, no confirmation required, hope the user can still use their account).. Don't you just love end users.
