Sendvio: Email Marketing & SMS

This app is easy to use, provides the capability to send THREE different e-mails, scheduled at different times (which is supposedly a "best practice" and yet many other abandoned cart apps do not do this), and seems to be effective. I'm like 3 days into my free trial for an $8 app and the program has already recovered $30 of sales for me. Definitely seems worth it!

Update: Now that I'm really in the full swing of thigns with this app, I love it even more. In the last 30 days, this app has helped me recover more than $1,000 in lost sales. Depending on your volume that might or might not be a big deal, but man, for $8 a month, that's a pretty mighty ROI.
