Here's a good reality check from Pro Copy Tips: Is your direct mail copy headed for the trash?
There are dozens of reasons the people you write to trash your message. But the main one is that you don't quite get around to telling them what they need to know.
The reason you do that is you're too wrapped up in the beauty of your copy or your brand. So never forget ...
... copywriting isn't art. It's selling. So don't waste your time rewording the seventh paragraph on the back panel of your brochure.... Focus on the offer. When people glance at your mailing, they're looking for what you're selling and the deal you're making to sell it. So make it good. Make it fast. And make it clear. Doubt fills trashcans.
Having a great offer -- and making it crystal clear -- that's what fundraising is about.
