Non-Profit Donation Strategies

Hey all,

I work with a non-profit who have been trying for a year or so to raise funds for a kids park to be built. They've been struggling to keep a steady flow of donations and have been mostly recruiting new donors through events and then trying to keep them engaged through email campaigns.

Does anyone have experience or recommendations on what digital tools or products or strategies would be beneficial for them to adopt in order to drastically increase their donations?
