Listen to Our Clients:"I wanted to take time to thank you for the exceptional email services you folks at LuxSci provide. I've been on the email scene since 1997, and since that time I've used countless free email accounts from companies such as Yahoo and Hotmail. Those free accounts worked in the beginning, but these days every SPAMMER and their brothers are targeting their users. Frankly I'm tired of having to weed through garbage when I check my email. Since I signed up with Luxsci back in the spring I haven't had a single piece of junk mail come through my mailbox. Between the SPAM filtering, white listing, black listing, and other tools that came with my account, nothing has gotten through that I didn't want. In addition to great email services, the support has been terrific as well. The few times I've needed assistance, I was very pleased with the response time. Thanks for providing such a great service!" Jeff Groendyke, Covington, KY |
