The verdict in three sentences
For a customer service team of 4 agents handling 1,200 emails a week, an AI agent for classification and reply drafting costs 10,000 to 25,000 EUR excl. VAT and about 80 to 300 EUR a month in API usage. The realistic gain is 35 to 50 % of handling time, the equivalent of 1.5 to 2 roles absorbed without hiring as volume grows. The success condition is simple: a human approves every outgoing reply, and data stays hosted in the European Union.
What the AI agent actually does
The agent reads each incoming email in the shared mailbox (Outlook, Gmail or a ticketing tool such as Zendesk or Freshdesk) and performs four tasks: it identifies intent (order tracking, quote, complaint, invoice, return), extracts useful data (order number, product reference, customer), queries the ERP or back office for status, and prepares a draft reply in the company's tone. The agent reviews, edits if needed and sends. Sensitive cases (disputes, cancellation threats, key accounts) are routed to a team lead first.
Project budget and running costs
| Item (2026 order of magnitude) | Essential version | Advanced version |
|---|---|---|
| Scoping and analysis of 2,000 historical emails | 1,500 EUR | 3,000 EUR |
| Classification and data extraction | 3,000 EUR | 5,500 EUR |
| ERP or back-office connection (order status, invoices) | 2,500 EUR | 7,000 EUR |
| Reply drafts with knowledge base | 2,000 EUR | 5,500 EUR |
| Approval interface in the existing tool | 1,000 EUR | 2,500 EUR |
| Quality dashboard and training | 0 to 500 EUR | 1,500 EUR |
| Total excl. VAT | 10,000 EUR | 25,000 EUR |
| EU-hosted language model API | 80 to 150 EUR a month | 150 to 300 EUR a month |
| Maintenance and continuous improvement | 150 EUR a month | 400 EUR a month |
API cost depends on volume: 5,000 emails a month with reading, classification and drafting amount to a few million tokens, usually under 0.05 EUR per email processed.
Measured gains and limits to know
| Indicator | Before AI agent | After 3 months (target) |
|---|---|---|
| Average time per email | 6 to 8 minutes | 3.5 to 4.5 minutes |
| Misrouted emails | 10 to 15 % | 2 to 4 % |
| First response time | 24 to 48 h | 4 to 8 h |
| Classification accuracy | Not measured | 90 to 95 % |
| Drafts sent unedited | 0 % | 40 to 60 % |
| Handling hours per week | 140 h | 75 to 90 h |
Three limits to keep in mind. The agent gets ambiguous emails wrong, hence mandatory human approval, which also meets the human oversight requirement of the EU AI Act. Customer personal data requires EU hosting and a GDPR-compliant processing agreement, with no reuse for model training, a point the Irish Data Protection Commission scrutinizes closely. Finally, draft quality depends on the knowledge base: up-to-date terms and return procedures are a prerequisite.
Mini case study
Ciara, customer service manager at a B2B technical supplies distributor in Dublin, runs 4 agents and 1,200 emails a week at 7 minutes on average, i.e. 140 hours weekly. With the AI agent, average time drops to 4 minutes: 60 hours saved per week, about 2,600 hours a year. At a loaded hourly cost of 35 EUR, that is worth 91,000 EUR a year. The advanced project costs 22,000 EUR excl. VAT plus 6,000 EUR a year for API and maintenance. Payback in about 3 months, and the autumn peak is absorbed without temporary staff.

FAQ
How much does an AI email triage agent cost for an SME?
Between 10,000 and 25,000 EUR excl. VAT in 2026, plus 80 to 300 EUR a month in API and 150 to 400 EUR in maintenance. Price depends mainly on ERP connections.
What time saving can we expect?
35 to 50 % of handling time after 2 to 3 months of tuning. On 1,200 emails a week, that frees 50 to 70 hours.
Can the AI reply to customers on its own?
Technically yes, but we advise against it for B2B service. Human approval keeps accuracy above 99 % on replies sent.
Does the data stay in Europe?
Yes, the project relies on models hosted in the European Union under a GDPR agreement that excludes training on your data. Logs are kept 30 to 90 days according to your policy.
How long does it take to set up?
Expect 6 to 8 weeks: 2 weeks analyzing historical emails, 3 to 4 weeks of development and a 2-week pilot with one agent.
