Sellizer

Tracks what happens to every sales proposal after you send it

Websubscriptionglobal

Sellizer tracks what happens to a sales proposal after it is sent, showing who opened it, how long they spent on each page, and which sections they returned to, with instant alerts and session replay. It is aimed at B2B sales teams who want visibility into buyer engagement instead of guessing why a deal went quiet.
