What do you like best?
Like a lot of these background processing systems you're really only going to hear about it when things go wrong. Vero provides us with a lot of support for triggering and maintaining email campaigns for our application.
It's simple to use and to date we haven't experienced any outages (knock on wood). That, combined with a clean and easy-to-use interface make this an ideal solution to our needs.
What do you dislike?
The only thing that comes to mind is the number of clicks required to see an actual email as it was sent to a customer. You have to find the customer, dig into the triggers, find the event, click a drop down, and finally click to see the email content. It'd be nice to have an easier way to get to the meat of the email.

Unlike most products, it's a bit harder to 'give it a try'...
That being said, go by the reviews (we did) and we were happy with our decision.
