Re-Engagement & Multi-Threading Strategies

Hi Everyone, 

I'm curious if any of you have any playbooks or can point to any solid resources on what Jake from Skaled recently mentioned on the GGR Podcast. 

Specifically - the challenges to overcome are 

1. how best to get customers back into conversations when they've gone quiet?
2. how to extend deeper across a customer organization so that you have more than a single-point-of-contact?

We are running much of the standard playbooks related to Topic 1 such as cold-email, Linkedin Outreach, touching base with other stakeholders within the organization, leveraging a QBR to entice re-engagement, offering to share custom reports in a call if they have time etc. 

Curious if you all have anything defined around these areas and would love to hear. 

Thanks!
