Here are five common fundraising mistakes. If you are making any of these, correct them today! 1. Thinking your major donors want to hear less from you. 2. Not calling foundations to find if there's a match before submitting your proposal or letter of intent. 3. Putting off your e-newsletter because no one is making you get it out every month. 4. Not starting your spring appeal in February because, hey, you have two months, right? 5. Being afraid to ask questions.
