Q: Did Not Receive Verification Email?

A: First check the spelling of the address and try requesting another verification email to be sent. If that doesn't work, check out some suggestions below.

1.Typo - Check to make sure the email address is spelled correctly. If not, verify the address with the correct spelling.

2.Web Browser Needs a Refresh - Occasionally you'll need to manually refresh your browser to check for new emails.

3.Spam or Junk Folder - Verification emails may be filtered directly into your email program's spam or junk mail folder. Your ISP or corporate domain may be configured to deliver commercial mail to this folder by default. If you do not find the email in this folder, try adding "@vip.163.com" to your safe sender list, then request another verification email to be sent.

4.Blocked or Bounced Address - If you tried to verify a specific email address but did not receive the verification email, your ISP or corporate domain may have blocked the email. Although Constant Contact averages a very low block rate of around 3%, it's possible that your email address may be part of that 3%. If you haven't received any Constant Contact emails, try verifying an alternative email address.

5.Role, Group, or Alias Address - Because multiple people may have access to a role email address, it's best to use a personal email address for your contact and billing address. Some role addresses can be verified, but many can't.
