Since HL wants to cover the complete funnel (from the lead gen to the close), having the possibility to display Call Scripts during calls would be a giant step forward.
If you or your client are calling leads from HL or you're set up with a Call Center, imagine the impact of having scripts in HL. Those scripts could even be filled with the contact's custom fields. This would create personalized scripts to boost your sales team by 10x.
Sharing a snapshot? Share your scripts as well! A tab could be created under "Phone Calls" for this feature.
In an ideal world, there would be a trigger to assign a script to a user. If a user purchases X, responds to x, opts in from x form, assign x script for the next call.
