Been using this cadence builder for awhile. Was posted by the VP of Sales for the company that build it. It's totally free to use whether your company partners with them or not. For clarity, my company uses one of their competitors, but I follow the VP from this company because he posts a lot of great advice.
The tool itself is great if you are struggling to build out a cadence. Helps you craft emails and steps of the cadence. Hope it helps!
P.S. Sorry about the vagueness... i don't know the rules about promotion on someone else's behalf.
