The verdict in three sentences
With 400 emails a day, an Amsterdam SME spends roughly 1.5 full-time equivalents just reading, sorting and routing messages before anyone even answers them. Triage by a language model costs 0.002 to 0.02 EUR per email, or 20 to 180 EUR per month in processing, and cuts first response time by 2 to 3 times. The real budget lies in integration with your ticketing tool and in GDPR and AI Act compliance, not in the API.
What AI triage actually does, and what it must not do
Automatic triage reads each incoming email, extracts the intent (complaint, order tracking, quote request, billing, cancellation), the urgency level and useful data (order number, customer reference), then sends it to the right queue. A suggested reply is offered to the agent, who approves or edits it. Nothing goes out on sensitive topics without human approval.
| Task | Before (manual) | After (AI + approval) | 2026 order of magnitude |
|---|---|---|---|
| Reading and categorising an email | 45 to 90 seconds | 2 to 5 seconds | 92 to 96% correct categories |
| Routing to the right team | 10 to 20% misrouted | 3 to 6% | Fewer internal transfers |
| Extracting the order number | Manual copy and paste | Automatic | 95% of fields recognised |
| Drafting a standard reply | 4 to 6 minutes | 1 to 2 minutes with suggestion | Human approval kept |
| Detecting urgent cases (dispute, churn threat) | As they come | Flagged immediately | Real-time prioritisation |
| First response time | 18 to 30 hours | 6 to 10 hours | Divided by 2 to 3 |
What it must not do: reply on its own to a complaint with financial stakes, decide on a refund, or process health data without a legal basis. The EU AI Act classifies this use as limited risk, with a transparency obligation if the customer interacts directly with an automated system. GDPR requires a record of processing, a review of processors and, ideally, data hosting within the European Union.
Full cost: API, integration and operations
The amounts below are 2026 orders of magnitude for 400 emails per working day, about 8,800 emails per month.
| Item | Light option | Robust option | Comment |
|---|---|---|---|
| API cost per email | 0.002 EUR (small model) | 0.02 EUR (large model, long context) | Depends on length and attachments |
| Monthly API cost | 18 EUR | 176 EUR | Negligible compared with salaries |
| Native AI feature in the ticketing tool | 30 to 60 EUR per agent per month | Included in top-tier plans | Limited customisation |
| Custom integration (Amsterdam market) | 8,000 EUR excl. VAT | 20,000 EUR excl. VAT | Ticketing, CRM, ERP, business rules |
| Kolonell custom application (medium tier) | 6,100 EUR (4 M FCFA) | 10,670 EUR (7 M FCFA) | Connectors, approval interface, dashboard |
| Hosting and monitoring | 50 EUR per month | 200 EUR per month | Logging, alerts, EU hosting |
| Kolonell maintenance | 50 EUR per month (35,000 FCFA) | 180 EUR per month (120,000 FCFA) | Category tuning, model updates |
The item most often forgotten is the labelling phase: you need 500 to 1,500 historical emails categorised by hand to calibrate and measure accuracy. Allow 3 to 5 days of work by an experienced agent. Without that baseline, you cannot tell whether the tool sorts at 80% or 95%.
Native feature or custom integration: the decision grid
| Customer service situation | Recommendation | Indicative starting budget |
|---|---|---|
| Fewer than 100 emails a day, one tool | Native AI feature in the ticketing tool | 0 to 2,000 EUR |
| 100 to 300 emails, standard categories | Native + additional rules | 2,000 to 6,000 EUR |
| 300 to 1,000 emails, CRM and ERP lookups | Custom integration | 6,100 to 20,000 EUR |
| Several languages, several brands | Custom with multilingual routing | 10,000 to 20,000 EUR |
| Sensitive data (health, finance) | Custom, EU hosting, audit log | To be scoped, DPIA required |

Mini case study
Femke, customer service manager of a 45-person e-commerce SME in Amsterdam (illustrative persona), runs a team of 6 agents handling 400 emails a day in Dutch and English. Manual triage takes an average of 1 minute per email, or 400 minutes a day, about 6.7 hours. After integrating AI triage for 9,000 EUR excl. VAT, this drops to under an hour of checking. Gain: around 5.7 hours a day, or 125 hours a month. At a fully loaded cost of 30 EUR per hour, that is 3,750 EUR per month, against roughly 200 EUR in API, hosting and maintenance costs. Payback: just under 3 months, before counting the effect of halved response times on customer reviews.
FAQ
What accuracy should we expect at launch?
On well-defined categories, 88 to 92% correct classification from the first week, then 94 to 97% after two or three tuning cycles. Ambiguous emails stay in a "to sort" queue handled by a human.
Are customer emails used to train the model?
With a properly configured business API, no: major providers contractually commit not to train their models on your data. Check the clause, the retention period (often 0 to 30 days) and server location.
Do customers need to be told AI is involved?
If a human approves every reply, the AI Act transparency obligation is lighter, but a mention in your privacy policy is still required under GDPR. For an autonomous chat agent, informing the customer is mandatory.
How long does the project take?
Allow 6 to 10 weeks: 2 weeks of scoping and labelling, 3 to 5 weeks of development and connection, and 2 weeks of parallel testing before switching over.
