Here are a whole bunch of fundraising copy tips from Karen Zapp's Nonprofit Blog: Keep it Simple. Keep it Friendly.
Here are most of them:
- Speak (I mean out loud) what you want to write. Then write what you said; how you said it.
- Write the P.S. first – your offer
- Don’t be a nit-pick grammarian.
- It’s NOT about your nonprofit
- Hero of your mission is the donor or member. Make this clear in your copy.
- Use a larger font, and one that’s easy to read
- Black (not gray) colored font on white background is the easiest to read; body of your copy ought to be black on white
- Short sentences. Short paragraphs.
- Letters should not look like a business letter. Indent paragraphs. Do not justify margins.
- Highlight key passages (bold; italics; or underlining)
- Tell a great story – master this art
- Clear call-to-action
- Use emotion, passion, and opinions
- Write for skimmers
- Employ direct response principles
- Show how donors make a difference
