It's something you can use to attract clients from scraped or purchased lists.
I'm not a fan of random email blasts, but I just tried one for the heck of it.
Wasn't really trying to sell, it was more of a test for a future campaign.
The subject line is used was:
"[name], other [insert profession] in [insert city] don't want you to see this..."
so for example
"Jake, other dentists in Houston don't want you to see this..."
You can expect quite a good open rate with this.
Of course, the sample list I had came with first names.
You may wanna try this out. Let me know how it goes!
