I do hyper-personalized outbound for executives from large companies. After doing deep research on a specfic prospect that a client wants to meet with, it is of upmost importance that I have the right email and right phone number, otherwise, all of the time spent on the research and personalization goes to waste. I've been using BetterContact and it has made it so I never need to worry about an email bouncing ever again. When it's time to make a call, I know that if BetterContact can't find the number, it's unlikely I'll find it anywhere else. I highly recommned this tool.
