Integration of online and direct mail fundraising has been a staple topic of development conferences for at least five years now. So it’s time to separate the results from the hype.
Yes, of course you should seek to integrate your mail and online programs, and the larger the programs, the more upside for integration. Of course, you want to enable your supporters to donate by whatever channel they choose for a given gift—the BRE, the donation page on your site, or plain unmarked bills delivered to your door.
While online giving has grown significantly over the last five years, most donors still give by mail. Just 9% of donors came in online in the most recent evaluation of 12 national organizations, but they account for 21% of new-donor revenue because of much higher gift levels. The online donors are younger and have higher household income (because they’re working, not retired).
Over the last three years, the donorCentrics ™ Internet Benchmarking program that my firm, Donordigital, has worked on with Target Analytics has shown that up to 25% of online-acquired donors make at least one gift online, but that few mail-acquired donors give online. When mail donors do migrate to online giving, their gifts are larger. And when online donors give in the mail, they give smaller gifts.
Some of the giving difference is certainly age—most online donors are over 60, many over 70, and these folks are less likely to give on. Habit also seems to be a factor: The longer a mail-acquired donor is on your file, the less likely she will make an online gift. However, these numbers are averages, and your file may differ, especially if you have a younger mail file (such as a group like Human Rights Campaign) or if earthquakes, hurricanes, or other high-profile emergencies motivate your mail donors to go online to give.
As you probably know by now, online donors have higher lifetime value than mail donors, mainly because their average gifts are so much higher. Multi-channel donors are even more valuable. But even mail donors with email addressees on file who have not given online are more valuable, either because the email messages they receive motivate them to give more in the mail or because the donors who offer you their email addresses care more about you. (What about donors whose e-mail addresses you have appended? We don’t have the data, but it could be they’re more affluent and/or younger than those for whom you can’t find an email address.)
So what should you do?
Add your online activists and subscribers to your direct mail acquisition program. They’ll often perform as well as or better than any non-house list—and they’re free.
Ask direct mail donors for their email addresses, and send your 0-24 month direct mail donorfile to an appending house such as FreshAddress or Tower Data for appending. That will cost 15 to 35 cents per matched name, depending on quantities.
Send email newsletters and/or advocacy action bulletins to your mail donors to give them additional touch points.
Send email appeals to your direct mail donors, either to repeat the message they’re getting in the mail or to fundraise during late-breaking opportunities when there’s no time to mail. Sending email to arrive just after the postal mail seems to increase response the most, but test it if your file is big enough.
Integrate your membership renewal efforts to make sure that supporters get the renewal message in the mail, in email, on the Web site, on your Facebook page, even in your tweets.
Don’t expect fundraising miracles from integration. The two donor groups are still separate, though there’s increasing convergence.
Ask your donors what they want—in surveys, focus groups, on the phone, and when you meet with them.
