Regarding the product we are promoting, it is still the erectile dysfunction encapsulated, we send the leads from facebook to whatsapp because on whatsapp we can present the offer in an extremely aggressive way!
I have good commissioned salespeople attending 1x1 on whatsapp, we try to extract the maximum from each lead, after all you invest money on his way to your whatsapp, we have some scripts, and many bonus goals, it's working...are you using some kind of tool to automate your conversions?
