After creating your CoolWorks account, you will need to confirm your email address for security purposes in order to log in. You will receive an email from "firstname.lastname@example.org" with the subject “Confirmation Instructions.” This email will ask you to activate your account by clicking on the “Confirm my account” link.
You will initially have access to your account. However, if you do not confirm the email address within 48 hours, you will be locked out and a new confirmation e-mail will need to be sent.
If you cannot find the original confirmation email, you can go to the login page and choose the “Resend Confirmation Email” link. If that still doesn't find its way to your inbox, be sure to check your Spam / Junk Mail folders. Additionally, you can try searching All Mail folders for "email@example.com" to search all folders (Spam, Junk, Trash, etc.).
