Click "You" on the top right corner of your page on GiveGab and from the drop down menu, select "Admin Dashboard" for the organization you'd like to access.
Step 2: Navigate to Your Donations Table
From the Admin Dashboard, expand the "Fundraising Tab" and click on "Donations" from the drop down.
Step 3: Resend Donor Receipt
From the donations table, find the donor you'd like to resend the receipt to, and click on the receipt icon in the "Actions" column in the same row as that donor.
Once your receipt has been re-sent you should see a confirmation at the top of the page. That receipt will be sent to whatever email address is currently associated with the donor's account.
