At Reddit, we use your email address to verify your account and (you guessed it) send you emails.
Verifying your account with an email address gives us a way to help you reset your password in case you forget it. If you don’t have an email address and you forget your password, you’ll be locked out of your account when you log out. (And that’s sad for all of us.) If you think you’ll forget your password, we highly recommend you verify your account.
What emails we send
Emails we send include newsletters about top and trending posts; notifications about direct messages, comments and replies, mentions, and other activity related to your account; and administrative emails about your account. If you don’t want to receive emails from us, you can always unsubscribe from the email itself or update your notification settings.
Verifying with a trusted domain
A trusted domain refers to a commonplace email domain that is from a well-established and trusted source. This includes gmail, apple, hotmail, outlook, or yahoo. When you create an account on Reddit and verify an email address with a trusted domain, it's one way to let us know that you're likely to use Reddit in good faith. If you'd prefer to use your own personal domain or another email domain, that’s okay too. Reddit has other ways to identify people using the platform in good faith, using a trusted domain is only one of them.
