I mean it is very unlikely and it does not seem worth spending hundreds of dollars a month to avoid.

If you are going to get hit it is not going to be because someone got your ip in an email or at least the odds are against it.

A "hacker" could simply create a valid looking account and receive the activation email. Then it's a matter of looking at the headers of the email and there you go, you got the server IP.

It indeed is very unlikely that someone will use this method to get your server IP, but it happens.
It doesn't cost hundreds of dollars though, I can last a long time with 100k emails for $50.
