You might want to reconsider that plan.
NPR did a great piece on political direct mail. It's definitely worth listening to, but here are two take-a-ways:
It's going to be noisy in the mail box
There is going to be a lot more mail in people's mailboxes. According to NPR, if you thought the political ads on TV were bad, you haven't seen anything yet. Political junk mail is about to hit.
So you may want to add another mailing or two to ensure your fundraising message is received.
Opt for earlier deadlines
If you use a mailhouse, move up your entire mail schedule by 2 weeks. Political mail slows down all mailings, at least for the smaller nonprofits--which are most of us. So build in some buffer time. It's far better that the letter your donor normally receives on December 15 gets to them on December 1 rather than January 2.
So build some margin into your schedule.
I'd encourage you to listen to the interview over at NPR. One of the direct mail experts has a great observation about plain mail vs. colorful graphics.
