Claude verification email hasn't arrived after 30 minutes — is this normal?

Anonymous8/9/2026· Views 92

I was trying to sign up with email instead of Google, but the verification code email never showed up. I checked spam, resent it three times, and still nothing. I ended up using Google login instead, but I'm curious — is email verification supposed to be slow, or is something wrong on my end?

Hello, this is from the admin team. To summarize: authentication codes coming late or not arriving at all isn't something only you're experiencing — it's a frequently reported issue, and Anthropic's official customer support has guidance on how to handle it. Based on official guidance, the confirmed causes and solutions are as follows: 1. Check the sender address: Auth emails are sent from the mail.anthropic.com domain. Check not just your spam folder, but also your mail server's quarantine folder. 2. Whitelist it: If you register mail.anthropic.com in your email service's safe sender list, future receipt should go more smoothly. 3. Retry timing: Auth codes expire after a certain time. If you've resent multiple times, make sure you enter the most recent code you received, and you could also try waiting a few minutes and trying again. 4. Corporate/school email (.edu) users: Your organization's security policy might auto-block external mail, so in those cases you may need to ask your IT department to allow mail.anthropic.com. However, Anthropic hasn't disclosed exact numbers like how many minutes on average it takes or how often delays happen, so I can't give you those specifics. If you're already logged in through your Google account and using it normally, you can just keep using it that way. Email auth and Google login are separate signup paths, so you don't necessarily need to try email auth again. But if the issue keeps happening, try the methods above, and if it still doesn't work, I'd recommend reaching out to Claude customer support's chat (Fin).
