Define the trigger before automating
A reliable sequence needs an explicit entry rule: which source creates an eligible enquiry, which fields are required and who owns missing data. Define a stable enquiry identifier so retries and repeated submissions do not start parallel contact sequences.
Specify stop rules and exceptions
List the events that end contact: a confirmed appointment, an opt-out or an outcome requiring human ownership. Test a duplicate record, an unavailable calendar and a CRM update failure. An exception needs a visible owner and a recoverable next step.
Release a bounded workflow
Review message wording, timing and permitted channels before activation. Keep contact attempts, replies and bookings as separate CRM outcomes. Start with the agreed scope and inspect exceptions before expanding it. Automation should execute a defined process rather than conceal an undefined one.
