The renewal letter lands on a Tuesday. Your customer opens it, sees a different number to last year, and rings to complain on Wednesday morning. Nobody called first to explain why.
That gap between the price landing and the phone ringing is where your support team spends its week. An AI voice agent for customer retention closes it from the other direction. It calls your customer before the letter arrives, explains the number in plain terms, and offers the fix on the spot.
Decagon, a US customer service AI vendor, launched a proactive outbound product called Proactive Agents in March 2026. Hertz is a named customer, using it to reach people before a problem turns into a complaint.
Waboom AI does not run on Decagon's technology and has no partnership with it. The two names simply prove the category is real. Outbound voice that calls first, not a sales dialler chasing a lead.
This piece walks through what that call looks like at an insurer's renewal, an energy bill spike, a telco rollover and a council outage. It also runs the cost math against Waboom AI's own economics, at roughly $0.80 NZD a minute.
What is a proactive outbound voice agent?
A proactive outbound voice agent calls your customer before your customer calls you. Not a cold sales call to a stranger who has never bought anything. A call to someone already on your books.
That distinction matters. Waboom AI's own outbound platform runs both models. The AI sales agent dials people who have not bought yet, working a lead list toward a first purchase.
A retention agent dials your existing customers instead. It works the account toward a renewal, a resolved bill, or a complaint that never gets raised.
Same dialler. Same voice engine. Completely different job.
You can run either mode, or both, from the same outbound platform for New Zealand and Australia. You just load a different list and run a different script.
Why do complaints and churn spike at renewal, a bill shock, or an outage?
Four moments cause most of your support team's complaints each month.
A renewal price higher than last year. A bill that spikes after a usage change. A plan rollover the customer did not choose. An outage with no warning.
None of those moments are avoidable. Prices rise. Usage changes. Networks fail.
What is avoidable is the silence around them. Your customer, opening that renewal letter cold, reads it as an ambush.
Call the same customer two days earlier and explain the number, and they read the identical price as expected news. Same price. Different reaction.
That is the whole mechanism behind proactive outbound. It does not remove the bad news. It just moves the moment your customer first hears it, from a cold letter to a warm call.
How does an AI voice agent for customer retention actually make the call?
An AI voice agent for customer retention runs off a trigger, not a schedule. Your system flags a renewal date, a bill above a threshold, a plan change, or an outage ticket.
The agent picks up that account. It dials before the letter, the invoice, or the outage notice reaches your customer.
On the call, it names itself and who it is calling for. It states the number changing and the reason in a sentence or two. No jargon.
Then it offers the fix. A payment plan, a rate held for another year, a cheaper plan, or a plain answer to why the number moved.
Every call gets logged against the account. Accepted the offer, asked a question, or wanted a person instead?
That outcome goes on the record, not into a call log nobody reads.
Decagon built this same mechanism into its Proactive Agents product. Vikram Rajagopalan, Hertz's VP of Customer Experience, described it this way: "Decagon gave us a way to shift from reactive support to proactive outreach, while empowering our team to focus on the customer interactions where the human touch matters most."
That quote is market proof the category is real, not a claim Waboom AI makes about itself.
The same voice platform running this outbound work is the one that can answer your phone. See the AI receptionist for New Zealand businesses for the inbound half of the same system.
What does this look like for an insurer at renewal in NZ or Australia?
Say you insure homes or cars, holding a renewal date for every policyholder. Premiums move most years, usually up, and the letter explaining why lands with the new number.
A proactive call ahead of that letter states the new premium and the headline reason: a claims year, a reinsurance cost, a change in cover. Then it asks whether the customer wants a review, or just confirms and rolls over.
Most calls end there, confirmed and logged. The rest get flagged to a human adviser, with the policy, the change and the question already captured.
Nobody re-explains the renewal from scratch on that human call. This is one slice of a wider job. Our AI voice agent for insurance brokers covers the rest: after hours calls and claim triage.
What does this look like for an energy retailer managing a bill spike?
A bill that jumps against last month's is a common trigger for a complaint call. Usage went up. A rate changed. A fixed term rolled to a variable rate.
Your customer does not know which. By the time the bill lands, the shock has already set in.
Run proactive outbound and any account with a bill spike over your normal threshold gets a call before that bill falls due. The call names the reason plainly. Then it offers what is on the table: a payment plan, a smoothed instalment, or a cheaper plan.
That call does not replace the bill or any notice you already have to send. It sits in front of that notice. The first thing your customer hears is a voice explaining it, not a bare number.
What does this look like for a telco plan rollover or a council outage notice?
A telco raising an old plan's price, or rolling a customer off an expired promotion, produces the same pattern as an insurance renewal. The reason lives on a page nobody reads. The complaint call follows within days.
A proactive call ahead of that change states the new price and the alternative plans on offer. It logs the decision: downgrade, stay, or ask for a person. All three get handled without one inbound call from your customer's side.
A council or utility outage works differently, but the logic holds. The moment an outage is confirmed, the same outbound system can call every affected address with what is happening and a rough restoration window.
That one proactive call absorbs most of the "is my street included" calls. Otherwise they flood your inbound line during the outage itself.
Swipe the table sideways to see what each proactive call does.
| Trigger moment | What normally happens | What the proactive call does instead |
|---|---|---|
| Insurer renewal | Renewal letter lands, price is different, customer calls to ask why | Explains the new premium and the reason before the letter arrives |
| Energy bill spike | Bill lands higher than usual with no context, customer calls to dispute it | Flags the spike, names the cause, offers a payment plan or a cheaper plan |
| Telco plan rollover | Promotional pricing ends, customer rolls to standard rate with no warning | States the new price and the alternative plans on offer |
| Council or utility outage | Service drops, every affected household calls at once to ask what is happening | Calls affected addresses with the cause and a rough restoration window |
Is it legal to call your own existing customers proactively in NZ and Australia?
Yes, with rules attached, and the rules differ by country.
In Australia, the Do Not Call Register Act 2006 targets unsolicited sales and marketing calls. A call about your customer's own account sits differently to a sales pitch.
It still has to name who it is calling for. It still has to honour an opt out in real time. The calling windows and public holiday blackouts sit under the ACMA business rules. Our Australian telemarketing law guide covers the rest.
New Zealand has no equivalent register. Your outbound calling here runs against the Privacy Act 2020 and the Marketing Association's voluntary do not contact list.
There is no single national switch to check before you dial. The suppression list is yours to build and yours to respect.
Either way, a retention call is not a sales pitch and should never sound like one. It names the caller, states the reason, and gets off the phone the moment your customer wants to end it.
Our guide to running inbound and outbound on one platform covers the basics. Read it before your first dial.
What does a proactive outbound retention campaign actually cost?
Waboom AI's own outbound numbers
- $0.80 NZD a minute is Waboom AI's own outbound calling rate.
- About 30 seconds is the average call length across Waboom AI campaigns.
- 47 to 65% connect rate on a typical Waboom AI outbound list.
- 20 to 25% success tag rate once a call connects.
Run the maths on a mid sized campaign. Say you have 5,000 accounts due for a renewal, a bill spike or a plan change this month. Each call runs about 30 seconds: introduce, state the number, offer the fix, log the outcome.
At $0.80 NZD a minute, 5,000 calls at 30 seconds each is about 2,500 minutes. That is roughly $2,000 NZD for the whole run. The figure is illustrative, built from Waboom AI's own per minute pricing, not a published case study number. Your AU numbers run on Waboom AI's AUD rate instead of this NZD one.
Not every dial connects. Waboom AI's campaigns run a connect rate of 47 to 65%. On a 5,000 call list, that is 2,350 to 3,250 calls reaching a person.
Of the calls that connect, a 20 to 25% success tag rate is typical across Waboom AI outbound work. Roughly one in four to one in five calls closes cleanly, no follow up needed.
Set that $2,000 NZD figure against your support team's cost of fielding those same complaint calls. Calling first stops being optional once those two numbers sit side by side.
Running outbound for new business instead of retention uses the same platform and cost model. Only the list changes. Full detail sits on our voice agent pricing page.
Our writeup on 800 calls out of a 44,000 record CRM shows the same dialling mechanics, applied to leads instead.
Frequently Asked Questions
What is proactive customer service, and how is it different from reactive support?
Reactive support waits for your customer to reach out. Proactive customer service starts the contact from your side, because something on the account is about to change: a renewal, a bill, an outage. The AI voice agent version calls before the letter or invoice lands, instead of waiting for the complaint.
How do AI voice agents reduce customer churn?
By moving the moment your customer first hears bad news, from a cold letter to a call that explains it and offers a fix. Decagon's Proactive Agents, live since March 2026, is one named example. Hertz is a named customer, using it to resolve issues before they escalate. Waboom AI runs its own platform for this, not Decagon's.
Can an AI voice agent call a customer before they complain?
Yes. That is the entire point. It triggers off an account event: a renewal date, a bill threshold, a plan change, an outage ticket. Then it dials before your customer finds out from a letter or an invoice.
How much does an outbound retention call cost?
At Waboom AI's rate of roughly $0.80 NZD a minute, a single 30 second retention call costs a small fraction of a dollar. Run 5,000 of those calls and you are looking at about 2,500 minutes. That is roughly $2,000 NZD for the whole campaign, an illustrative figure, not a published case study number.
What is the difference between an outbound sales call and an outbound retention call?
A sales call dials someone who has not bought yet, working a lead toward a first purchase. A retention call dials someone who already has an account with you: a renewal, a bill, an outage. Same outbound platform, opposite direction.
