You’ll always have some people pledge who never follow through.
There seem to be three categories of this kind of giver:
1) The person who pledges and never gives.
2) The person who pledges, gives a few times and then isn’t heard from again.
3) The person who pledges and gives seldom and randomly thereafter.
Of these, the first two are most common in my experience. Dealing with non-giving pledgers is tricky business. You don’t want to seem too eager to get their gifts by sending a slew of reminders, but some communication is prudent. Do take into account the personality and circumstances of the giver when deciding how to approach them. Some people have good and sincere intentions but simply forget, every month. Some people may be out of a job or lose a job after committing to a regular donation. If said donor is generally jovial, I’m more likely to approach them more often and more bluntly.
Two things I’ve leaned on are thank-yous and Christmas gifts. We’ve made a practice of sending donors small notes of thanks in the middle of the year, as well as inexpensive gifts around Christmastime. I use these as a reminder to people that they are a part of the team, although after a certain “point of no return” — that is, if a person hasn’t given for, say, 18 months or more — I’ll drop them from the thank you list.
In truth I don’t think this tactic has actually revived any of the non-giving pledgers. Even the two, that I can think of, “jovial” donors that I’ve given face-to-face or phone reminders to haven’t begun giving regularly, or at all.
Thus it seems to be a fact of living on support: You’ll always have some people pledge who never follow through. Plan on it when creating your budget and fundraising strategy!
