Owners Not Receiving Invite Emails

If your owners are not receiving their invite emails:

You may have misspelled their email address in the invite.
Double-check with the owners that haven't received their invite the spelling of their email address, and that you entered it correctly in FanDraft.
The emails may be landing in their email JUNK/SPAM folder.
Inform the owners that haven't received their invite to check their email Spam/Junk folder, and/or search for emails from "draft@fandraftonline.com"

If neither of the above options work, owners can also login or register into their FanDraftOnline account. Once logged-in they will see a link to join your league (provided that you sent it to the same email address that they register with).
