How does this work when you sign up to a new service and they send an email confirmation to verify your email? Surely it’s a similar situation?
Many services require email confirmation, that is right. But this is not required immediately. I can do this hours later. Some services even allow it to do days later.

Yeah fair enough. I’ve never used Greylisting before, is there not some folder you can go to to view the emails which have been deleted due to first contact? Like the spam folder or something?
That isn't how grey listing generally works, no
Even in the case of a long delay - this is a one-off event, as opposed to login which could be a daily occurrence.

My understanding of Greylisting is that there’s only a delay the first time someone contacts you so this shouldn’t be a problem
That's not the only reason emails may be delayed.
First: email is not a reliable way of communication. Emails can be delayed. That means, a service using this method has lost me before I even had a chance to look into the details of the service.
Second: my email is deliberately delayed for services who contact me first. It is called Greylisting and still to theses days it works great as a spam protection without consulting and relying on some (dubious) blacklist providers. That comes back to the first point. A service using this kind of on-boarding has lost me before I even had a chance to look at it.
