SenderScore.org should not be in business. It overcharges, under delivers, and does not honor its contractual services. The development of their work was slow and tedius with very little assistance on their part. It took forever to get someone to assist me. Then, when it was time for renewal, SenderScore automatically charged my credit card without my authorization. When I protested this charge, they posted some now negative and false accusations on the internet. When I called Sender Score to resolve this matter, I was told there is nothing they could do for me. I asked to speak with their CEO and was told they could not transfer my call. They said I would need to send him an e-mail.
