Cost to serve: phone versus automated engagement in protection
The question is not whether to keep people talking to customers. It is how to make sure their time is spent on the conversations that need them.
The hidden cost of a call
An outbound call looks cheap until you count everything: dialling attempts, voicemails, call-backs, the minutes spent on calls that go nowhere, after-call work, management and the fully loaded cost of the person making it. For a post-sale check or review invitation, many attempts produce no conversation at all, because customers increasingly ignore unexpected calls from numbers they do not recognise.
What automated engagement changes
A branded digital journey can reach every customer in a cohort at once, at a marginal cost close to zero per message. Customers respond when it suits them. Responses arrive structured and recorded. Only the customers who need a conversation are passed to a person, and that person starts with the full picture.
Comparing like with like
The fair comparison is cost per outcome rather than cost per contact: cost per completed check, per issue surfaced, per review requested or per policy saved. Phone campaigns typically have high cost per outcome because so many attempts produce nothing. Automated journeys have low cost per outcome because the effort is front-loaded into design and the platform.
What we see
Across Adviser.ai clients, delivering engagement through automated journeys has been up to 14 times cheaper than doing the same work by phone, with examples above 10 times in live deployments. The range depends on the product, the firm's existing process and how it was costed. The direction is consistent: the more repetitive the task, the larger the saving.
Where people still matter most
Automated engagement does not replace advisers or service teams. It removes the repetitive work of finding the customers who need help, so people can spend their time helping them. Advice, complaints, affordability conversations and vulnerable customers all still need a person, and they get better service when that person is not tied up dialling.
Building the case
Start with one process, such as post-sale checks. Calculate the current fully loaded cost and the outcomes it produces. Estimate the same outcomes through an automated journey, including the time needed to handle routed responses. Then add the value of the extra outcomes: more issues found, more policies kept, lower clawback. The saving on cost is usually the smaller part of the return.
Costing a phone process properly
To compare fairly, include every element: the fully loaded hourly cost of the person making calls, the average number of attempts per completed conversation, average call and after-call time, supervision and quality assurance, telephony, and the cost of call-backs. Many firms find the cost per completed outcome is several times higher than they assumed.
Costing automated engagement properly
Include the platform cost, any set-up and design time, the time needed to handle routed responses, and ongoing management. Because the routed responses are the ones that genuinely need a person, the handling time is spent on productive conversations rather than finding the customer.
Using the freed capacity
The most valuable effect is often not the saving itself but what the team can do instead. Time no longer spent dialling can go to resolving issues faster, supporting vulnerable customers, handling reviews customers have requested or giving advice. That improves outcomes without increasing headcount.
Beyond cost
Automated journeys also improve consistency. Every customer receives the same approved wording, every response is recorded and every flag is routed in the same way. That makes the process easier to evidence under the Consumer Duty and easier to improve, because changes can be tested and measured across the whole book rather than relying on individual call handlers.
A worked example
Suppose a team makes post-sale calls to 1,000 new customers a month, needing an average of three attempts to complete each one, with around a third of customers never reached. Counting attempts, conversations, after-call work and supervision, the cost per completed check can be substantial. An automated journey sent to the same 1,000 customers reaches all of them, completes at a higher rate and passes only the customers with issues to the team. The total cost falls, and the number of issues found rises.
