Or the user typos their address and it goes to the void or to someone else. Even a valid address can’t be assumed correct. I get a ton of emails to my old gmail that aren’t meant for me because some people are too dumb to get their email addresses correctly (even for someone’s covid vaccination appointment confirmation and details recently...) or just make a mistake.
