Good SMS automation is event-driven, permission-aware and easy to interrupt.
Automate predictable timing and routing. Keep judgment-heavy conversations human.
Useful trigger types
Lead event
A form or inquiry creates a contact and, where appropriate, starts a timely response.
Appointment event
A booking, confirmation, reschedule or approaching appointment triggers a relevant reminder.
CRM event
A pipeline stage or task status changes which follow-up is needed.
Time event
A sequence waits until a sensible interval instead of sending multiple messages at once.
Every workflow needs stop conditions
- Stop when the person opts out.
- Stop or branch when the person replies.
- Stop when the appointment is booked or status changes.
- Stop duplicate flows triggered by the same customer event.
- Stop promotional steps when the permission basis does not cover them.
- Escalate unusual replies to a person.
Automate state, not persuasion
Automation is excellent at checking whether a lead has replied, whether an appointment exists or whether a task is complete. It is weaker at interpreting emotional context, complex objections or unusual circumstances. Design the sequence around known states and clear handoffs.
