I ran Earth Class Mail as CEO for a couple years and loved my time there. I am still a customer for our MovingCompanyReviews.com business and finally got around to writing a review for it, including a bunch of screenshots, pricing, and a breakdown of the features (including their check deposit). Check it out here – Earth Class Mail Review.
Quick aside about their check deposit service – I used to love it, but for the two checks we get per month, $10 per check was just enough to dissuade me not to use it. Instead I just print out a Chase deposit slip and mail it in.
