Highly targeted opt-in email values?

[Matt 26z]

How much more valuable are highly targeted opt-in addy's?

Like instead of just "these people are interested in porn" addresses, they are borken down into asian, black, hardcore, teen, etc...

I'd just like to know if it would be worth the extra effort of going this route. I would certainly think it would be.....

I'm sure you'll get a load of people shouting Spam at you in a minute, but just ignore em. Genuine opt-in lists are a great marketing tool - and, as with all marketing, the more targeted you can get, the better.

Just be sure you use genuine opt-in lists. Spamming is not only uncool, it's unproductive! The best way to be sure, and to get highly-targeted addresses, is to build your own list.
