Zelesta × ArminCX

Zelesta got rid of making the bed. You know the drill: duvet out, cover on, stuff it back in, sweat, swear. Zelesta solves it with a duvet that combines cover and filling in one. Toss it in the washing machine, done. What started five years ago in the Netherlands now sells in eight countries. Over a million orders. Around 40 employees. New team members every week.

That exact growth was the problem. Zelesta noticed: more orders meant more tickets. And more tickets meant only one thing so far: hire more people. The automation rate sat at 0%. AI drafting ran through a separate plugin, the helpdesk through Trengo. Two tools, double the effort, no real progress. Something had to change.

The choice was ArminCX. One system for everything: incoming tickets, AI handling, workflows, analytics. Since the migration, wrapped up in around six weeks, Zelesta's support runs on a different level.

"It almost feels like 24/7 support, even though people obviously sleep. I've never experienced support like this from any other software company."

What changed

From two separate tools and 0% automation to one central inbox that resolves over 45% of tickets fully automatically.

Two tools, double the work

AI drafts ran through an external plugin, the helpdesk through Trengo. Anyone who wanted to change something had to work in two systems. If one of the tools decided to stop playing nice with the other, the team faced chaos.

Growth without automation

Every single request was handled manually. No workflows, no AI, no relief. The only lever to keep up with growth: hire more people.

No consistent round-the-clock support

Evenings, weekends, right after a launch: customers got answers when an agent was available. Or they didn't. A consistent tone of voice across eight countries and every shift was basically impossible.

Scaling only through headcount

More orders, more tickets, more agents. A growth model that gets proportionally more expensive the more successful the company becomes. Not built to last at triple-digit annual growth.

"At some point we realized we just kept having to hire more people to maintain a certain level of customer experience. That's exactly what we wanted to change."

How did Zelesta set up ArminCX?

Before the migration, a lot ran in parallel at Zelesta: Trengo as the helpdesk, an external AI plugin for draft messages, and a growing team holding both together. The plan was clear: one system that does it all. The migration itself was done in around six weeks. Two years of ticket history came along. No data loss.

Step 1: Connect channels and systems

WhatsApp and email were added as central channels in ArminCX. Alongside that: Shopify integration for real-time order data, a connection to the 3PL Monta for shipping information, Returnista as return software, Klaviyo for marketing sync, plus Amazon Seller and Trengo. From that moment, every agent sees at a glance what a customer ordered, how much they spent, and where their order currently stands.

Step 2: Train the AI

The AI Agent was trained on the Zelesta knowledge base and the Shopify product data. For WhatsApp, the rule is: the AI is the first line. It tries to solve every request either through a workflow or the knowledge base. With the Shopify sync, the AI Agent has access to product information no human agent can match. Product availability, order status, return requests: fully automatic.

Step 3: Set up workflows

The most important live flows: WISMO (where is my order, this one flow alone has run over 100,000 times), return requests routed straight to Returnista, product questions with a Shopify lookup, and smart escalation for edge cases. For email, a mixed mode runs: 35% go out fully automatic, for the remaining 65% the AI creates a draft that the agent adjusts with a few keywords and sends.

The strategy behind it

Draft reply for sensitive topics

Draft reply for sensitive topics

Not every request belongs in auto-send. For complex cases, or when a customer needs more attention, ArminCX creates a ready-made suggestion. The agent adjusts it with a few keywords and sends. Same tone of voice, no waiting time, no loss in quality. For Zelesta, this applies to a large share of email tickets, with AI involvement over 90%.

Smart escalation on WhatsApp

Smart escalation on WhatsApp

The AI Agent on WhatsApp decides for itself: solve it alone, or escalate. This logic makes sure agents only see the cases where a human is actually needed. Routing runs automatically, categorization happens in the background.

Multilanguage across eight markets

Multilanguage across eight markets

Zelesta sells in eight countries. All markets run under one setup in ArminCX, from WhatsApp to email to the Meta integrations. Customers write in their language, the AI replies in their language. The team keeps an overview of every market in one inbox, with no separate accounts or tool instances.

Continuous AI training

Continuous AI training

Zelesta actively pushes the automation rate higher. Whatever the AI Agent gets wrong, or wherever it escalates, gets flagged and corrected by the agents. The AI learns with every ticket. The result: an automation rate that grows instead of stalling.

"Thanks to the Shopify syncs, our AI Agent has access to information no human agent can match. Those tickets get solved pretty easily."

The results are simply crazy.

The results

30,000+

Tickets per month

Zelesta doubled the volume compared to before the migration, from 15,000 to over 30,000 tickets per month. Across WhatsApp and email combined, in eight countries, in one inbox. Without proportionally more headcount.

97%

Resolution Rate

Nearly every request gets closed successfully, because the structure is right: the right integrations, smart escalation, AI for the routine.

>45%

Automation Rate

0% before, over 45% fully automated now. Total AI involvement sits at 99% on WhatsApp and over 90% on email. Practically every reply that goes out was written or prepared by the AI.

Your support. On autopilot.

ArminCX takes over the routine so your team can focus on what really matters.

Relieve the team, don't replace it

The AI handles the routine. Order status, tracking, returns, invoices, fully automated. Your team is freed up for the cases where judgment and empathy matter.

Respond instantly. Around the clock.

Customers get an answer in seconds, not hours. At night, on weekends, after a launch. The AI never sleeps, so your team can again.

Continuous AI training

The AI gets better with every round of agent feedback. What it gets wrong gets corrected, what it gets right gets reinforced. The automation rate climbs over time, not the other way around.

"It shouldn't matter whether you send a message on a Wednesday at 8 PM or a Sunday at 1 PM. You should always be able to expect the same level of consistency, tone of voice, and helpfulness. That's exactly where the platform helps us get better every day."

From zero to live in a few weeks

From zero to live in six weeks. Zelesta approached the migration in a structured way: first migrate Trengo, then connect channels, train the AI, and go live. The automation rate grew from 0% to over 45% in a few months.

Week 3–4

Train the AI & finish integrations

Knowledge base built, product data from Shopify added, Monta and Returnista connected. First workflows tested.

Week 5–6

Go-live & first optimization round

All channels live, smart escalation active, first monitoring. The automation rate starts and grows from here on.

4

From month 2

Automation rate climbs

Agent feedback improves the AI. New workflows come on board. Zelesta drives the rate from 0% to over 45% in a few months.

Ongoing

Optimize & scale

New flows, continuous AI training. Growth through automation, not new hires.

Frequently asked questions

Everything you want to know about how ArminCX works at Zelesta.

Zelesta handles over 30,000 tickets per month across WhatsApp and email combined, in eight countries, in one inbox. That's double the volume compared to before the migration.

Over 45% of all WhatsApp requests are resolved fully automatically with no human involvement. On email it's 35% fully automatic, plus over 90% AI involvement on drafts. Total AI involvement sits at 99% on WhatsApp. Before the migration, the automation rate was 0%.

Zelesta uses six integrations directly in ArminCX: Shopify for real-time order data and automatic WISMO responses, Monta (3PL) for shipping and fulfillment data, Returnista for automated return requests, Amazon Seller for marketplace communication, Klaviyo for syncing support data into marketing flows, and Trengo as a sync layer for remaining processes.

The migration was done in around six weeks. The first two weeks covered data migration from Trengo (including two years of ticket history) and channel setup. Weeks three and four were used for AI training and integrations. In weeks five and six, all channels went live. The automation rate then climbed continuously to over 45%.

The 97% resolution rate is the result of the right combination: Shopify integration for real-time order data, smart escalation so complex cases go straight to the right agent, and AI for all routine requests. Practically every request gets closed, because no ticket gets lost in the wrong channel.
