A service advisor calls a customer about an extra job found during a service. No answer. They try again after lunch. Still no answer. By the time the customer calls back, the technician has moved on to the next car and the job has to wait for a second visit. Multiply that across a service department’s daily workload and a meaningful part of the day goes to repeated call attempts rather than the work itself.
Why phone calls struggle as a default channel
Phone calls have three structural problems for this kind of communication: they require both people to be free at the same moment, they leave no record either party can refer back to, and they can’t show anything. Describing a worn brake disc over the phone is a worse experience for everyone than sending a 20-second video of it, and it’s also slower, since the advisor has to describe what the video would have shown in a single glance.
Where each channel actually wins
Situation | Better channel | Why |
|---|---|---|
Routine service reminder | No real-time coordination needed; async confirmation is enough | |
Extra work found mid-service | Video and a specific figure replace a verbal description and a guess at cost | |
Significant unexpected repair cost | Phone, then WhatsApp to follow up | Tone and reassurance matter more than documentation in the moment |
First-time customer, no existing trust | Phone | A voice conversation builds trust faster than a first message from an unfamiliar number |
Post-service feedback | Documented, asynchronous, higher completion than email |
What changes in practice
WhatsApp solves the async and documentation problems directly. Messages sent through Cue see open rates above 90%, compared with roughly 40% for calls, because the customer can read and respond whenever they’re free rather than needing to answer at the exact moment the advisor calls. The conversation is also documented: what was said, what was approved, and when, sits in the thread rather than in someone’s memory of a call.
This isn’t a case for eliminating phone calls entirely, and the table above is the honest version of that: complex or sensitive conversations, a significant unexpected repair cost, a first-time customer who hasn’t yet built trust with the dealership, often still benefit from a real-time conversation where tone matters more than documentation. The practical shift most dealerships make isn’t replacing calls with WhatsApp everywhere. It’s moving the routine, repetitive communication onto WhatsApp and keeping calls for the moments that genuinely need them.
What this looks like in practice
Dealerships using Cue for aftersales communication have seen up to a 50% reduction in inbound calls to the service desk, freeing advisors to spend more time with customers in front of them rather than working through a call list.

A note on where this is heading
AI-answered phone calls are becoming a real category in automotive customer communication, not a future concept; at least one direct competitor already ships this today. Cue’s own roadmap includes voice capability, though it is not live at the time of writing, and this article doesn’t describe it as available. If you’re specifically evaluating AI voice handling as part of a platform decision, see Fuzey vs Cue for a direct look at where that stands today.
