Trengo vs Formlyy: omnichannel inbox or commercial WhatsApp agent?
Jun 17, 2026 · 10 min read · By Arthur Goudard
When customer messages come from everywhere, companies often want one thing first: a clean inbox.
WhatsApp, email, Instagram, Facebook Messenger, live chat, calls, SMS. Each channel has its own urgency and history. When everything is scattered, the team loses time before even replying.
Trengo solves that problem: centralize customer conversations in an omnichannel inbox with automation, AI and team collaboration.
Formlyy solves a more specific problem: leads generated by campaigns or forms must be contacted on WhatsApp, qualified, followed up and turned into qualified appointments.
The choice is not “which tool manages messages?”. It is: do you have a conversation organization problem, or an inbound lead conversion problem?
The short answer
Choose Trengo if you want to centralize WhatsApp, email, chat, social channels and other customer conversations for several teams.
Choose Formlyy if you want to convert inbound leads into appointments: WhatsApp contact, qualification, follow-ups, booking, CRM and sales context.
| Need | Trengo | Formlyy |
|---|---|---|
| Omnichannel inbox | ✓ | × |
| Multichannel support and customer service | ✓ | × |
| Team collaboration on conversations | ✓ | × |
| Post-form ad lead follow-up | × | ✓ |
| Structured sales qualification | × | ✓ |
| Follow-ups until appointment | × | ✓ |
| Handoff to the right salesperson | × | ✓ |
| Qualification data for Ads | × | ✓ |
Trengo organizes conversations. Formlyy turns inbound requests into opportunities.
Two different jobs
Omnichannel inbox
- 1
Customers and prospects write across channels
- 2
Conversations arrive in a shared inbox
- 3
Team replies, assigns, automates and collaborates
- 4
Requests are better organized
- 5
Success is measured by handling efficiency
Outcome: infrastructure to maintain
Commercial WhatsApp agent
- 1
Lead arrives from Ads, landing page or form
- 2
Agent contacts the lead on WhatsApp
- 3
It qualifies based on sales criteria
- 4
It follows up and proposes a slot if relevant
- 5
Sales receives a qualified appointment with context
Outcome: qualified appointments
If your issue is post-form conversion, WhatsApp lead qualification is closer to the problem than an inbox guide.
Where Trengo is stronger
Trengo is stronger when the pain comes from scattered conversations.
Examples:
- teams reply on WhatsApp, email, chat and social channels;
- several agents need to collaborate in one inbox;
- you want to avoid lost messages;
- you manage support, customer service or operations;
- not every conversation is commercial;
- you need an omnichannel view of customer relationships.
In this context, Trengo makes sense. The topic is conversation organization.
Where Trengo can be insufficient for acquisition
A centralized inbox is not always enough to convert ad leads.
You still need to define:
- the first WhatsApp message;
- contact delay;
- qualification questions;
- follow-ups;
- disqualification rules;
- appointment proposal;
- sales summary;
- data sent back to CRM and Ads.
That is the difference between an inbox and the full chain of ad forms, CRM and calendar.
Where Formlyy is stronger
Formlyy is more relevant when leads come from campaigns or forms and need to become opportunities quickly.
The agent contacts each lead on WhatsApp, qualifies the need, filters weak profiles, follows up, proposes an appointment and sends context to sales.
Comparison by priority
| Priority | Trengo | Formlyy |
|---|---|---|
| Centralize all customer channels | ✓ | × |
| Improve support collaboration | ✓ | × |
| Reduce lost conversations | ✓ | × |
| Automatically recontact inbound leads | × | ✓ |
| Qualify before appointment | × | ✓ |
| Follow up silent prospects | × | ✓ |
| Send context to sales | × | ✓ |
| Improve ad targeting with qualification | × | ✓ |
The choice depends on the main problem: message organization or commercial progression.
A concrete example
A brand receiving many customer requests through email, WhatsApp, chat and Instagram can choose Trengo to centralize and reply more efficiently.
A company generating 150 form leads per month through Ads has another problem: prospects must be contacted while intent is warm, qualified, followed up and booked with the right salespeople.
Here, speed-to-lead and the qualified appointment matter more than omnichannel breadth.
Final recommendation
Trengo is relevant if you need an omnichannel inbox for customer conversations.
Formlyy is more relevant if your issue is acquisition: turn every inbound lead into a qualified conversation, then into a useful appointment.
The practical question is: do you want to organize messages better, or convert requests better?
