I don't think mercury minds have an autorespoder. You can find a complex one at MagneticOne with a looooot of features. If you want something simpler and much cheaper, take a look at our Message Machine (
http://www.cartonsteroids.com/Message-Machine/).
We have implemented until now on:
- a flower shop: send reminder to clients in 364 day from complete order
- a herbalife seller: send instruction to clients in days 3, 7, 12, 18, 24 and 40.
- a DVD shop: asking clients to make a movie review 6 days from shipping
