The issue is that, from the charity's standpoint, your most likely donors are those who have already donated. It would be nice if you could volunteer a higher donation in exchange for a promise not to be mailed / emailed for a year or two (or ever). I donate to a public radio station on a monthly basis, and some months I feel like they're putting that entire donation into efforts to market to me.
