Features
Recursos projetados para transformar o atendimento no segmento de vendas.
Create segmented lists and send personalized messages to thousands of contacts simultaneously.
Library of pre-approved messages by Meta to ensure delivery without the risk of banning.
Schedule messages for peak engagement times with a visual campaign calendar.
Track delivery, read, and response rates for each campaign in real-time.
Send messages to thousands of contacts simultaneously with segmentation by tags, location, or behavior.
Create dynamic segments based on recent activity, stage in the funnel, or previous interactions with chatbots.
The campaign is sent from the verified company number, with an approved template. Sending from a cloned device is the quickest way to lose the number — and with it, the entire conversation history.
The person who bought in the last ninety days, who opened the last campaign, who is at a certain stage of the funnel. The audience is built by rule, not by a copied spreadsheet.
Those who request not to receive exit all subsequent sends automatically. It's not a box someone needs to remember to check: it's the platform's default behavior.
Name, purchased product, expiration date, and amount are included in the text. The same campaign reaches each person differently, and the response rate reflects that difference.
The text goes through Meta's approval and the platform tracks the status. You find out that the model was rejected before the campaign, not in the middle of it.
The campaign goes out on the day and time frame you set, respecting the contact's time zone. A commercial message at eleven at night is the fastest way to become a complaint.
The delivery is spread out over time instead of being sent all at once. This protects the quality of the number and prevents the team from receiving a thousand responses in the same minute.
Send to a small group, see the response rate and the content of the responses, and only then release the rest. A bad campaign for a hundred contacts is a lesson; for ten thousand, it's a crisis.
How many arrived, how many were read, and how many generated conversation. It's the third number that indicates if the campaign worked — the first two only show that it went out.

Disorganized pipeline and cold leads lead to loss of productivity and below-expected results.
Teams of 5-30 employees
Manual conversion and closing processes do not scale as the business grows.
Companies with out-of-hours support
Customers expect immediate responses, but the team only works during business hours.
Starting from 3 users
You have a large base of old clients that no one has contacted for months because calling them one by one is unfeasible.
Starting from 3 users
Lose revenue due to absence and need to confirm dozens of appointments per day without occupying the reception.

What's changing
No segmentation, the choice is between sending nothing and sending to everyone. The first wastes the database; the second burns the number. The middle ground is the audience built by rule.
In practice
Four steps, and the third is what most tools ignore: test before sending to the entire database.
Funnel stage, date of last purchase, and consent determine who enters — no copied spreadsheet.
The text goes through Meta's approval, and the platform notifies the status before the launch.
One hundred contacts, reading the results, and only then the rest. A bad campaign becomes a lesson, not a crisis.
Those who respond go into the team's queue with the campaign marked, not into a box that no one opens.
