If you're like me and use postal mailings as part of your fundraising campaign, then you probably keep a pretty exhaustive address book. But people move, and occasionally that book needs to be updated. Fortunately, the holiday season is a great time both to keep in touch and to update your addresses.

As you send holiday cards this month, consider this opportunity to check in on past and potential supporters. There is plenty of overlap between friends, family, and donors, but for those who fall solely in the "donor" camp, they may appreciate a brief note to thank them for their support in 2009 and to remind them that you'll soon be fundraising for the MS Challenge Walk 2010.

This additional holiday task needn't be stressful! An online service like Click2Mail lets you design a postcard online, and they'll print and ship it for you for as little as 43 cents each, which includes all production and postage costs. First Class mail will return the postcard to you if it proves undeliverable, often with a forwarding address you'll be able to use when you send out your next round of fundraising solicitation letters.

Your donors will appreciate hearing from you, and you'll be getting the information and encouragement you need for another year of fundraising. You can do all this for just a few dollars, right from the comfort of your own computer. Your thoughtfulness will truly be in the spirit of the season!

Ken joined the MS Challenge Walk in 2005, more than a decade after his mother was diagnosed. After walking for three years and 150 miles, he switched to the support crew and now rides his bicycle along the trail, providing whatever encouragement (and snacks!) he can to the 600 walkers. He is also an alumnus of the event's steering committee and is this site's webmaster.
