Playbooks
These playbooks turn a sending or list-management problem into an ordered workflow. The dormant-list revival playbook is the starting point: establish eligibility, scan address risk, define a fixed cohort, stream gradually and measure what happens without hiding paused or excluded traffic. The platform playbooks add the account-state and billing context needed to apply that method in a particular tool. Read their dated checks alongside the official documentation for the account and plan you actually use.
A playbook is useful when the team can identify the next action, the evidence needed to continue and the condition that should stop the work. These resources keep permission, technical validity, current engagement and billable status separate. They also distinguish a calculator scenario from a measured recovery result. Begin with the pillar below, choose the platform-specific guide that matches your system, and use the linked checklists and examples to make the operating plan concrete. The listing includes only reviewed, indexable resources.
Start with the collection pillar.
