Invite emails can take at least 30 min

@MathisBullinger I don't know if you can check when the email invites were sent but they can take a long time to arrive in my inbox. I used gmail plus notation (https://gizmodo.com/how-to-use-the-infinite-number-of-email-addresses-gmail-1609458192) but I don't think that should affect the time they take to arrive.
