Don't leave potential donations on the table! As you get your campaign on a roll, think about ways you'll be able to fill your fundraising gaps.
One idea is to dig into your database for donors who haven't yet given this year but gave in the past. To get a list of lapsed donors, use the "Pattern" tab in a data mining operation.
After obtaining the list, you can review the accounts for ways to communicate with them. Maybe you have a home contact you can get in touch with, a related person whom you can call, a staff member who knows them, or someone may remember them from an event they volunteered at or attended. You might even be able to find more info by searching for them on Google!
