From The Daily Egg blog, here are 12 Strategies to Boost Email Marketing Click Through Rates. These are aimed at commercial marketing, so make sure to bend these to your own donors and your offer:
- Numbered Lists
- Ask Questions (like "Can I get your opinion?")
- Focus on [Donor] Interests
- Say It With Symbols (Unicode symbols can show up in subject lines)
- Be Clever (but not too clever!)
- Timing (pay attention to the days of the week and times of day that work best for you)
- Pretend You're on Twitter (tightly crafted short messages can work well)
- Provide a Call to Action
- Take Advantage of Preview Text (many recipients can see part of your message before they open it; put the interesting stuff at the top where those folks can see it)
- Use Trigger Words
- Be Specific
- Give Incentives
