Loving the RSD software!

Like my first chemistry class, sometimes it takes awhile for the proverbial light to go on. RSD is bad ass stuff. Thanks for your guidance. I have some learning to do but love the way it works.

I just want to say that this software (RED) is amazing! It has been such a game changer for me. I have been pulling my hair our trying to find a free/affordable way of designing emails for company. Nothing else compares to what you guys offer.
