So, what ESP do you use? What's your favorite?
I've used ExactTarget for about 5 years, and Eloqua for 1. (I've also dabbled in Strongmail and Mailchimp, but I'd like to forget both of those experiences.)
I guess I'm just curious about what everyone uses/loves/hates. It's been a while since I've used anything besides ET, so I'm curious if it's still the best in the business.
