I got iContact a couple months ago and for mixed use, both BH and WH they've been great. Saw it mentioned in the thread but not in much detail.

Here's why I like it...No double optins necessary for new subscribers, you can import your own email lists without them having to opt in (HUGE BENEFIT), deliverability's been great, it's incredibly easy to use, etc.

Though it can get a little expensive as your list grows, you should be making some nice bank to fund the extra costs. Just the fact that I don't have to deal with double optin at all if I don't want to makes it a winner for me.

It's perfect for Greyhat marketing...
