Using pabbly to create automated cold outreach sequence


I wanna use pabbly for cold outreach. I wanna connect it to my account and collect leads and then
1. connect it to whatsapp and create some sort of a sequence which has automatic follow ups which pauses only for the leads which reply me back and continue for the others
2. I wanna do the same sequence with SMS using twilio.

Can you please tell me the entire sequence on how to make this process because I'm in urgent need and will buy your plan ASAP.
