"Worth the investment. Winmo provides excellent cross referencing between client/agency relationships, providing contact info for client side and agency teams."
"If your prospects are in the advertising and marketing arenas, Winmo is the best option out there. We searched hard and trialed several others, and all fell short on quantity/quality of emails and phone numbers, not to mention accurate contacts. So far, our 'delivered' and 'open' rates are much higher since using Winmo."
