What are the best practices for sending emails to your app users?

Is it better to send emails async or sync and why?

Typically async is best in order to return the response promptly, but make sure the async job never sends the email more times than it is supposed to!

Whoa! That was fast. Thank you. I hope you don't mind that I ask again. Is it better to store user verification code in the user table to in a different table?

Not sure what the verification code here refers to.

However, I always try to keep the main user table as lean as possible. The verification code can be in a join table, and then a sort of isVerified property on the user table.
