Creating a G2 account using your business email requires that you submit that email and create a password before a verification email is sent to your inbox.
If you received the verification email but the link is expired, you may have already verified your account. Try going to your G2 profile to see if your account lets you log in. If it does, you’re all set, otherwise keep reading!
Sometimes our verification emails are caught by spam filters, so you may not have seen yours. Check the spam folder for an email from noreply@g2.com with a verification link. Otherwise, you can try to create an account using your LinkedIn login, since that does not require a verification email.
