Features
Recursos projetados para transformar o atendimento no segmento de sdr.
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 sends for times of highest engagement 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.

Segments
Prospecting operations that benefit the most from targeted bulk sending.
SMEs with 50+ interactions/day
Low connection rates with decision-makers lead to lost productivity and below-expectation results.
Teams of 5-30 employees
Manual prospecting and qualification processes do not scale as the business grows.
Companies with off-hours support
Clients 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.
Starting from 3 users
They need to inform about timelines, instability, or changes before the client finds out on their own and opens a ticket.
Starting from 3 users
They concentrate billing on a few dates and need to activate the entire base in a short window.
Starting from 3 users
They need to reach out to the entire overdue portfolio, not just the contracts that the team can call.

Where the conversation flows to

What's changing
Every operation with a few years has a base of people who talked but didn't close. Calling everyone is impossible; ignoring them is throwing away the investment already made to bring them in.
In practice
Reactivation is a low-rate, high-volume campaign. It only works when the audience has already spoken with you and when there is someone to attend to those who respond.
Own base, with registered consent. Purchased lists do not count — and shouldn't.
Mentioning the previous conversation is what separates warming up from a cold approach.
The sending is distributed throughout the day to protect the quality of the number and the team's queue.
The response goes to the SDR queue with the previous history attached, not as a new lead.
