I am not receiving the sign-up confirmation email

Try in this order:

1. Check Spam / Junk and, on Gmail, also the Promotions and Updates tabs.
2. Search by sender: noreply@endu.info.
3. Make sure you typed your email address correctly when signing up: a typo is the most common cause.
4. Add noreply@endu.info to your safe senders and use Resend code on the confirmation page.
5. If you use a work email address, your provider’s spam filter may block the message: try a personal address.

Did you misspell your email? Sign up again with the correct address: the attempt with the wrong address expires on its own within 24 hours and causes no problems. The same applies if you switch from a work address to a personal one: the first one becomes available again after 24 hours.

Until the email is confirmed the account is not active: login does not work and neither does “Forgot password”. You can find all the details in I tried to sign up and it says “Registration failed”.
