What your customer sees

How it works

Live in an afternoon

01
Choose the audience
Use a saved segment or ask AI to build one: past buyers of a category, high-value customers, people who browsed but never bought.
02
Write the message
Images, video, buttons and catalog cards. Brand AI drafts the copy; you approve it and submit the template to Meta.
03
Schedule and send
Send now, schedule for the sale start, or let AI send at each customer's best time.
04
Measure revenue
Delivered, read, clicked and revenue per campaign, next to your email and SMS results.

Segments, not blasts

Every marketing message costs money and attention. Sending to the customers most likely to buy keeps costs down and keeps people from blocking your number.

AI-built segments from purchase and browsing data
Exclude recent buyers automatically
Frequency caps across channels
One-tap opt-out handling

Direct Cloud API, no markup

Contlo is a direct WhatsApp Cloud API provider. You pay Meta's per-message rate for each delivered message and nothing on top.

Example: India, festive season

A Diwali launch to 40,000 customers

Instead of messaging the whole list, a brand on Contlo can split the launch:

01Early access to past festive-season buyers the evening before
02Launch-day broadcast to everyone who bought or browsed in the last six months
03A last-day reminder only to people who clicked but didn't buy
