- Confirm the backer’s username or email directly on Kickstarter.

- It is not uncommon for backer to forget the email used on Kickstarter or to have a typo in their email address. It’s possible that the backer is in Crowd Control, but needs updating.

- Confirm the backer has paid.

-If payment was not collected from a backer via Kickstarter then they will not be in Crowd Control. Direct dropped backers to your website to capture payment for their pledges.
