Isn't that pretty much the definition of "confirming your email address" transactional emails? Wouldn't really call this "sneaky".
- dpwm 5y agoI read it as anyone – including spammers – who puts link in will get a head request to it from the email provider, thus providing information – even if just that the address is real. However, the absence of a bounce probably also does that, albeit less reliably.
- gmueckl 5y agoSome email providers don't bounce/reject specifically to not leak that information as far as I know.
