The best feature of chekelaos tool was that it gives us good insight about our customers as well their buying behavior in real time which helped me understand my client's needs better than any other marketing tools we have used before! It also helps you track all your prospect data very easily once integrated with Salesforce, so no issues at this point :) We are using checkealo for tracking leads generated through different campaigns like email or social media etc where I can see how many times they visited website/social profiles / clicked links from emails - All those actions help build trust & relationship between sales team member''s profile page (checkeloo).
