I've been trying to find a provider like yours for months. Something I can afford and get support during the evening and night time hours when I do most of my web work. Benchmark is too expensive and they go home at 3:00pm my time with no support available.
We were so happy with the results and service, we doubled our mailing schedule!
I can't tell you how wonderful you are. I was a COBOL programmer and to find this kind of responsiveness in tech support is amazing.
