Donors probably understand that giving monthly will help your organization do more good, but their day-to-day life will largely go unchanged if they switch from a one-time donation to a monthly gift. Nonprofits need to go the extra mile to try to encourage donors to switch their one-time gift to a monthly basis.
Create a custom campaign for those donors that will come back to donate every once in a while and use the ‘After Donation is Submitted’ Monthly Reinforcer. Explain to them why you need recurring gifts and what impact they have. Donors want reassurance that their monthly gift is going to make a difference, so it is important to explain exactly what that donation will accomplish.
