My email sign-in link has not arrived. What can I check?

Check the spelling of the email address, then check spam or junk and any filtered inbox tabs. Give the message a little time to arrive instead of requesting many links quickly. Use the newest link you requested; sign-in links expire and can only be confirmed once. If a link is expired or already used, request a fresh one and complete Confirm sign-in. If delivery still fails, contact CookieSensei privately with the email address and approximate request time. Never publish the sign-in link or token in a Community screenshot.
