Approvals

You see the plan and its price before anything runs. Sends and posts go out within the limits you set; one approval rule on a class such as send makes every action in it wait for you, and going over a limit always asks.

It asks youWhenAnswered by
A save offer outside the PolicyThe offer is not on the cancel Policy’s listYou

Each class and its default amount: the hub’s approvals page.

Works with

  • Referral ask (agent task): Each week, your five happiest customers asked for one introduction each, by a note naming the outcome they got from you.
  • Upgrade note at the limit (agent task): A customer at 80% of a plan limit in, one note out with their numbers and the next plan’s price, at most once a month.
  • Save and win back (agent task): A customer at risk in, and within 24 hours one note out with the offer your Policy allows that fits their usage.

It trades hand-offs with AE, Onboarding, Head of customers, Billing and Partnerships.

Example

Northgate Rentals has not logged in for 9 days, twice its usual 4. The agent sends one check-in that names the unreconciled ledger, and Rosa Alvarez replies the same morning.
