I apologize if this is old news to some of you, but I thought I'd share a famous type of email that can help revive dead or unresponsive email lists. And it's only 9 words. I can verify that this kind of thing can work. Especially if you have nothing left to lose and want to see who's still out there in your email list.
This is not mine. It's from the I Love Marketing Podcast with Dean Jackson and Joe Polish. It's a transcript of the audio. ALL of it is gold, but the first 20 pages or so are concerned with the "9 word email." Let me know what you think.
