Customer reactivation · WhatsApp + calls
Next month's bookings
are already in your customer list.
Your system already knows when each customer is due again. Sono reaches them, WhatsApp first and then a call, and books them back in.
Your own customers, with marketing permission. Never cold lists.

Customer reactivation is outreach to a company's existing customers when a recurring service falls due again. Sono runs it end to end: a WhatsApp message, a call to anyone who doesn't reply, the booking, and the outcome written back.
The problem
The due date passes.
Nobody makes the contact.
Your booking system already knows when each customer is due. Working that list means thousands of small contacts, each worth one appointment and none of them anyone's job. So it sits unused.
The reminder goes to whoever is easy to reach, in whichever month someone remembers. The rest book elsewhere, or don't book at all.
One month of your customer base
Who's due — and who actually hears from you
The pale dots are the problem: a month of customers whose next service is ready to book, waiting on a contact nobody has time to make.
Your numbers, not ours
What's the due-date list worth?
Set your three numbers and see what a month of worked due dates is worth.
Customers reaching their next service date in a typical month.
Your assumption for how many contacted customers rebook.
What one rebooked appointment is worth on average.
Arithmetic on your own figures, not a Sono claim. What Sono changes is coverage: every due customer gets contacted, not just the ones somebody got to.

How it works
From a due date to a booked slot
One contact, on whichever channel the customer actually answers.
Step 01
Sono gets the due list
A CSV of customers, due dates and permissions, or a direct connection to your booking system.
Step 02
WhatsApp goes first
What's due, when, and an easy way to say yes. People answer messages long before they answer phones.
Step 03
Sono calls the rest
Everyone who doesn't reply gets a real conversation: questions answered, "not right now" handled, a time agreed.
Step 04
The outcome goes back
Booked, declined, call me in autumn, opted out — every result comes back as a file, or straight into your system.
What actually happens, day by day
One example cadence. Each step fires only if the one before it went unanswered — and the customer drops out the moment they book, decline or opt out.
Eleven months after the last service, thirty days before a contract ends — whatever the rule is in your business. Sono watches for it.
The reminder in writing, with a time already on offer. Reschedules, questions and "who is this?" are handled in the same thread.
Sono rings twice at different times of day, so one bad moment isn't the end of it. A real conversation: what's due, questions answered, a slot agreed.
A final WhatsApp with the offer to book, in case the calls came at a bad week. After that Sono stops and the contact is closed.
None of this is fixed. The trigger, the gaps between steps, how many times Sono calls and every word it says are set with you at kickoff — and changed in minutes, not sprints. Run a different cadence on part of the list and compare what comes back.
The primary channel
WhatsApp that
answers back.
A reminder is only worth sending if the customer can reply. Most tools send a template and stop, so "can you do the week after?" never becomes a booking.
Two-way, not a broadcast
Reschedules, "how long does it take?", "who is this?" — all answered in the thread, in the customer's own language.
It closes, not just reminds
Sono offers real slots, confirms the one they pick and writes the booking back. No call to your reception needed.
Read where people actually read
The message sits with their family and their plumber, and waits until they're free. A missed call just stays missed.
Opt-out in one word
"STOP" ends the sequence everywhere, messages and calls alike, and comes back to your records.
Where it works
If the service repeats,
there's a list to work.
Always the same pattern: a customer you have, a service that repeats, a date you know. Only the wording changes.
Dental & healthcare
Six-month check-ups, hygienist visits, vaccination rounds, annual reviews.
The ask · book the next appointment before it goes stale.
Opticians & audiology
Annual eye tests, lens subscriptions, hearing checks and device servicing.
The ask · book the test, and mention what's new in store.
Vehicle inspection & car sales
Inspections coming due, service intervals, leases ending, test-drive invitations.
The ask · book the slot before they drive to the next garage.
Home & building services
Heat-pump and HVAC servicing, chimney sweeping, alarm contract renewals.
The ask · get the annual visit booked without a phone-round.
Fitness & wellness
Memberships up for renewal, PT packages running out, class packs expiring.
The ask · renew before the lapse, not three months after it.
Insurance & financial reviews
Policy renewal windows, annual portfolio check-ins, pension reviews falling due.
The ask · book the review while the window is still open.
Permission first
A reminder only works
if it's welcome.
The contact has to feel useful, not intrusive. That's not a compliance box; it's what keeps the response rate up.
Your customers only
People who already buy from you, about a service they already use. No cold lists, no bought data.
Marketing permission required
You tell us who has given permission. Nobody else is contacted, in any channel.
Opt-out honoured instantly
"Don't contact me again" ends it on the spot, in every channel, and comes back so your records match.
Sono says what it is
It identifies itself as an AI assistant calling on your behalf, respects time-of-day rules, and records every message and call.
What you get
Customer reactivation
in practice
Not the ones someone had time for — all of them, every month, on the day they come due.
A message reaches the people who never pick up; a call reaches the people who never read it. Running both turns a reminder into a booking.
They chose you once and the service is genuinely due. The shortest distance from contact to invoice you have, at no acquisition cost.
While the customer is already talking, Sono can raise a relevant new product. A mention, not a pitch.
Booked, declined, "call me in October", opted out — with reason, transcript and timestamp. A file at first, written into your system once integrated.
FAQ
Frequently asked
questions
Outreach to your own customers when a recurring service falls due — a check-up, an inspection, an annual service. Sono contacts them by WhatsApp and phone, then books the appointment or hands over a ready-to-book lead.
No. Only your existing customers, and only those with marketing permission. No strangers, no bought lists — the relationship and the due date already exist.
WhatsApp first, because people reply to a message faster than they answer a phone. Anyone who doesn't reply gets a call — twice the same day — and then one final message. The cadence is agreed with you and easy to change.
Not to start. Most begin by sending a list of due dates and getting outcomes back — live in days. Later Sono connects to your DMS, booking system or patient record and handles both ends itself.
You tell us who has marketing permission; nobody else is contacted. Sono identifies itself as an AI assistant, honours opt-outs immediately, respects time-of-day rules, and records every message and call.
Any business with a long consumer list and a service that repeats: dental and healthcare, opticians, vets, vehicle inspection, HVAC and heat-pump servicing, chimney sweeping, gyms, insurance renewals.
Yes. The reminder is the reason for the contact, but Sono can raise a relevant new product in the same conversation. A mention, not a pitch.
