To verify your email address, go to My Profile and select "Phone Verification" from the completeness bar. This can be found on the right-hand side of the page (desktop) or by scrolling to the bottom of your profile (mobile).
From there you will be redirected to a page that looks like this:
Log in to your email account and look for the email in your inbox. If you do not see the confirmation email in your inbox, please check your junk/spam folder to make sure it didn't get filtered out by your email provider.
The verification email would look something like this:
Once you've found the email, click on the "Confirm Email Address" link. You will be automatically redirected to the site and your email will be confirmed.
If you still do not see the confirmation email in your inbox or junk/spam folder, go back to the email verification page and click "Resend Confirmation Email." A new email will be automatically generated and sent. You should receive it within a few minutes.
