Sometimes email falls through the cracks and doesn't make it to your inbox. Once the email is sent from our servers, we don't know what happens to it. We've passed on the email and trust that your mail server will deliver it to you.
Emails from CollaborNation
All emails from CollaborNation will have a From header from firstname.lastname@example.org. You might consider adding this domain to your address book and/or asking your network administrator to whitelist them.
If you're using a public email tool (such as Hotmail, Gmail, Outlook.com, etc.) and are having trouble receiving your confirmation email, try adding email@example.com to your contacts list.
Check Spam Locally and on the Network
Emails can get caught in spam filters. Check the spam folder in your email inbox to see if it's there. If it's not in your local spam folder, ask your network administrator if the message might be blocked at the network level.
