Before You Use This Email
Why This Approach Works
Platform Setup Steps
Trigger
A recurring retainer charge fails on an active agreement with no cancellation, dispute, or human billing case.
Segment
Primary Client Contact For Active Retainer With Failed Charge records that pass consent, current-state, ownership, exclusion, and source-system checks.
Delay
Within four hours after the current retainer, agreement, and processor records reconcile.
Reply owner: Agency Account Manager responsible for the current record, recipient reply, exceptions, and workflow stop conditions.
- Reconcile the source record, eligibility, consent, exclusions, owner, and required variables.
- Send the template with one action and record the exact version, event, and delivery state.
- Stop conflicting automation, route replies to the owner, and update the downstream stage after resolution.
Stop conditions
- Stop on reply, opt-out, human handling, complaint, dispute, or safety escalation.
- Stop when the action completes, the source record changes, or the recipient becomes ineligible.
- Stop on a higher-priority workflow, cancellation, account closure, or expired timing window.
Mistakes To Avoid
- Sending from a stale or incomplete source record
The recipient may receive an unavailable offer, wrong status, or unsupported consequence.
Use instead: Reconcile required fields and fail closed when any material value is missing.
- Letting automation continue after the recipient responds

Use instead: Make replies, resolution, disputes, and human handling immediate global stops.
Sequence Placement
Use as a standalone billing recovery message only after the verified trigger and eligibility checks pass; stop immediately on resolution, reply, record change, or human handling.
