- Sending your year-end solicitation within a month of when the donor made his/her most recent donation.
- Losing track of the donor's preferred title of address. Don't send me a letter that starts with "Dear Mr. Hirsch."
- Claiming, even humorously, that you're the charity most worthy of receiving donations. This could be funny in boom times. In a year when employment in Alameda County is close to 12%, the economy is in the tank, and there's a lot of suffering, not funny and not persuasive from a small arts organization.
