Guest post by Peter B. Wylie and John Sammis
No, this is not the last time I’ll write about Phonathon, but after today I promise to give it a rest and talk about something else. I just wanted to round out my post on the waste I see happening in donor acquisition via phone programs with some recent findings of mine. Your mileage may vary, or “YMMV” as they say on the listservs, so as usual don’t just accept what I say. I suggest questions that you might ask of your own data — nothing more.
I’ve been doing a thorough analysis of our acquisition efforts this past year. (The technical term for this is a WTHH analysis … as in “What The Heck Happened??”) I found that getting high phone contact rates seemed to be linked with making a sufficient number of call attempts per prospect. For us, any fewer than three attempts per prospect is too few to acquire new donors in any great number. In general, contact rates improve with call attempt numbers above three, and after that, the more the better.
“Whoa!”, I hear you protest. “Didn’t you just say in your first post that it makes no sense to have a set number of call attempts for all prospects?”
You’re right — I did. It doesn’t make sense to have a limit. But it might make sense to have a minimum.
To get anything from an acquisition segment, more calling is better. However, by “call more” I don’t mean call more people. I mean make more calls per prospect. The RIGHT prospects. Call the right people, and eventually many or most of them will pick up the phone. Call the wrong people, and you can ring them up 20, 30, 50 times and you won’t make a dent. That’s why I think there’s no reason to set a maximum number of call attempts. If you’re calling the right people, then just keep calling.
What’s new here is that three attempts looks like a solid minimum. This is higher than what I see some people reporting on the listservs, and well beyond the capacity of many programs as they are currently run — the ones that call every single person with a phone number in the database. To attain the required amount of per-prospect effort, those schools would have to increase phone capacity (more students, more nights), or load fewer prospects. The latter option is the only one that makes sense.
Reducing the number of people we’re trying to reach to acquire as new donors means using a predictive model or at least some basic data mining and scoring to figure out who is most likely to pick up the phone. I’ve built models that do that for two years now, and after evaluating their performance I can say that they work okay. Not super fantastic, but okay. I can live with okay … in the past five years our program has made close to one million call attempts. Even a marginal improvement in focus at that scale of activity makes a significant difference.
You don’t need to hack your acquisition segment in half today. I’m not saying that. To get new donors you still need lots and lots of prospects. Maybe someday you’ll be calling only a fraction of the people you once did, but there’s no reason you can’t take a gradual approach to getting more focused in the meantime. Trim things down a bit in the first year, evaluate the results, and fold what you learned into trimming a bit more the next year.
I recently read a question on a listserv that prompted me to respond. A university in the US was planning to solicit about 25,000 of its current non-donor alumni. The question was: How best to filter a non-donor base of 140,000 in order to arrive at the 25,000 names of those most likely to become donors? This university had only ever solicited donors in the past, so this was new territory for them. (How those alumni became donors in the first place was not explained.)
One responder to the question suggested narrowing down the pool by recent class years, reunion class years, or something similar, and also use any ratings, if they were available, and then do an Nth-record select on the remaining records to get to 25,000. Selecting every Nth record is one way to pick an approximately random sample. If you aren’t able to make this selection, the responder suggested, then your mail house vendor should be able to.
This answer was fine, up until the “Nth selection” part. I also had reservations about putting the vendor in control of prospect selection. So here are some thoughts on the topic of acquisition mailings.
Doing a random selection assumes that all non-donor alumni are alike, or at least that we aren’t able to make distinctions. Neither assumption would be true. Although they haven’t given yet, some alumni feel closer affinity to your school than others, and you should have some of these affinity-related cues stored in your database. This suggests that a more selective approach will perform better than a random sample.
Not long ago, I isolated all our alumni who converted from never-donor to donor at any time in the past two years. (Two years instead of just one, in order to boost the numbers a bit.) Then I compared this group with the universe of all the never-donors who had failed to convert, based on a number of attributes that might indicate affinity. Some of my findings included:
Using these and other factors, I created a score which was used to select which non-donor alumni would be included in our acquisition mailing. I’ve been monitoring the results, and although new donors do tend to be the alumni with higher scores, frankly we’ve had poor results via mail solicitation, so evaluation is difficult. This in itself is not unusual: New-donor acquisition is very much a Phonathon phenomenon for us — in our phone results, the effectiveness of the score is much more evident.
Poor results or not, it’s still better than random, and whenever you can improve on random, you can reduce the size of a mailing. Acquisition mailings in general are way too big, simply because they’re often just random — they have to cast a wide net. Unfortunately your mail house is unlikely to encourage you to get more focused and save money.
Universities contract with vendors for their expertise and efficiency in dealing with large mailings, including cleaning the address data and handling the logistics that many small Annual Fund offices just aren’t equipped to deal with. A good mail house is a valuable ally and source of direct-marketing expertise. But acquisition presents a conflict for vendors, who make their money on volume. Annual Fund offices should be open to advice from their vendor, but they would do well to develop their own expertise in prospect selection, and make drastic cuts to the bloat in their mailings.
Donors may need to be acquired at a loss, no question. It’s about lifetime value, after all. But if the cumulative cost of that annual appeal exceeds the lifetime value of your newly-acquired donor, then the price is too high.

Most alumni have never given a cent to their alma maters. “Whoa!” you may be saying, “What’s your evidence, fellows? That’s hard to swallow.”
We would agree. It’s not a pretty picture, but it’s an accurate one. For some documentation you can read “Benchmarking Lifetime Giving in Higher Education”. Sadly, the bottom line is this: In North America the lifetime hard credit alumni participation of at least half of our higher education institutions is less than 50%. If you look at only private institutions, the view is better. Public institutions? Better to not even peek out the window.
We do have a bit of optimism to offer in this paper, but we’ll start off by laying some cards on the table:
So … what’s the optimism we can offer? First, we’ve had some success with building predictive models for donor acquisition. They’re not great models, but, as John likes to say, “They’re a heck of a lot better than throwing darts.” In the not too distant future we plan to write something up on how we do that.
But for now we’d like to show you some very limited data from three schools — data that may shed just a little light on who among your non-giving alums are going to be a bit easier than others to attract into the giving fold. Again, nothing we show you here is cause for jumping up and down and dancing on the table. Far from it. But we do think it’s intriguing, and we hope it encourages folks like you to share these ideas with your colleagues and supervisors.
Here’s what we’ll be talking about:
One of the schools is a northeastern private institution; the other two are southeastern public institutions, one medium size, the other quite small.
The data we collected from the schools
The most important aspect of the data we got from each school is lifetime giving (for the exact same group of alums) collected at two points in time. With one school (A), the time interval we looked at stretched out over five years. For the other two (B and C), the interval was just a year. However, with all three schools we were able to clearly identify alums who had converted from non-donor to donor status over the time interval.
We collected a lot of other information from each school, but the data we’ll focus on in this piece include:
The result that we paid most attention to in this study is that a greater percentage of new donors came from the ranks of recent grads than from “older” grads. To arrive at this result we:
Notice in Chart 1 that, as the graduation years of the alums in School A becomes more recent, their likelihood of becoming a new donor goes up. In the oldest quartile (1976 and earlier), the conversion rate is 1.2%, 1.5% for those graduating between 1977 and 1990, 3% for those graduating between 1991and 1997, and 7.5% for alums graduating in 1998 or later. You’ll see a similar (but less pronounced) pattern in Charts 2 and 3 for Schools B and C.
At this point you may be saying, “Hold on a second. There are more non-donors in the more recent class year quartiles than in the older class year quartiles, right?”
“So maybe those conversion rates are misleading. Maybe if you just looked at the conversion rates of previous non-donors by class year quartiles, those percentages would flatten out?”
Good question. Take a look at Charts 1a, 2a, and 3a below.
Clearly the pool of non-donors diminishes the longer alums have been out of school. So let’s recompute the conversion rates for each of the three schools based solely on previous non-donors. Does that make a difference? Take a look at Charts 1b, 2b, and 3b.
It does make some difference. But, without getting anymore carried away with the arithmetic here, the message is clear. Many more new donors are coming from the more recent alums than they are from the ones who graduated a good while back.
Now let’s look at the three other variables we chose for this study:
Specifically, we wanted to know if previous non-donors with a home phone listed were more likely to convert than previous non-donors without a home phone listed. And we wanted to know the same thing for business phone listed and for email address listed.
The overall answer is “yes;” the detailed answers are contained in Charts 4-6. For the sake of clarity, let’s go through Chart 4 together. It shows that:
Looking at Charts 5 and 6 you can see a similar pattern of differences for whether or not a business phone or an email address was listed.
What comes across from all these charts is that the variables we’ve chosen to look at in this study (year of graduation, home phone, email, and business phone) don’t show big differences between previous non-donors who converted and previous non-donors who did not convert. They show small differences. There’s no getting around that.
What’s encouraging (at least we think so) is that these differences are consistent across the three schools. And since the schools are quite different from one another, we expect that the same kind of differences are likely to hold true at many other schools.
Let’s assume you’re willing to give us the benefit of the doubt on that. Let’s further assume you’d like to check out our proposition at your own school.
A Makeshift Score That You Might Test at Your Own School
Here’s what we did for the data we’ve shown you for each of the three schools:
We created four 0/1 variables for all alums who were non-donors at the first point in time:
For each alum who was a non-donor at the first point in time, we created a very simple score by adding each of the above variables together. Here’s the formula we used:
SCORE = Youngest Class Year Quartile (0/1) + Home Phone Listed (0/1) + Business Phone Listed (0/1) + Email Listed (0/1)
An alum with a Score of 0 was not in the Youngest Class Year Quartile, did not have a home phone listed, did not have a business phone listed and did not have an email address listed. An alum with a Score of 1met only one of these criteria, but not the other three, and so on up to an alum with a score of 4 who met all the criteria.
Charts 7-9 show the relationship of the Score to new donor conversion. We’d like you browse through them. After you do that we have a few concluding comments.
Some final thoughts:
