There is a ton to unpack in here. Some thoughts
- See my slides on lifecycle setup from 2015 Summit.
- SDR follow up - often done with Tasks in SFDC or you can train them to change a field like Lead Status from MQL > SAL. That should trigger other things and be reportable. Nurture really has nothing to do with this.
- SFDC Campaigns - parent-child. Yes. depends what you want.
- Reporting - what do you want to report on?
Do you know if there's a way to report on Lead activity from SFDC? For example, my reps will log activity (calls, emails) to Leads as well as Contacts, and I need to build a report of Leads that have either NO outbound activity, or the last activity was longer than 5 months ago. Is this possible?
