Unsubscribe and Opt-out Management for Every Channel

Why opt-outs deserve proper attention

Every campaign reaches some people who are not interested. That is normal. What matters is what happens when they say so. If someone replies "STOP" on WhatsApp and gets another message the following week, they are likely to block or report your number. If a parent asks not to be called and the next voice campaign rings them again, your institute's name is the one they remember, for the wrong reason.

Respecting opt-outs is good manners, it supports compliance with platform rules, and it is also good business. It keeps your sender reputation healthy and stops you spending money on people who have already said no.

How Smart Growth AI handles opt-outs

WhatsApp

Templates can include a simple opt-out option, such as a "Stop promotions" button or an instruction to reply STOP. When someone uses it, the number is marked as opted out for promotional messages.

RCS

RCS messages can carry a similar opt-out action. Requests are recorded against the number in the same way.

SMS

Promotional SMS follows India's DLT framework and DND preferences. Opt-out requests received for your campaigns are stored so those numbers are left out next time.

Voice calls

Requests not to be called again, whether through the call itself or passed on by your team after a conversation, are added to the same opt-out list.

What happens before every new campaign

• You upload or select a contact list.
• The platform checks it against your opt-out records.
• Opted-out numbers are removed from promotional sends on the channels concerned.
• The same filtered list is used to build Meta retargeting audiences, so opted-out people are not shown your follow-up ads either.

This happens without anyone needing to remember to clean the list by hand.

Promotional versus important messages

Someone who says "no more offers" may still need a fee receipt, an appointment confirmation or an exam date. We help you separate promotional campaigns from genuine service messages, so stopping one does not cut off the other. Service messages should still be relevant and expected, not promotions in disguise.

Opt-outs and the Smart Growth AI Campaign

The Smart Growth AI Campaign is built on the idea of stopping waste: people who listen for under 10 seconds get no paid follow-up at all. Opt-out management takes the same thinking one step further. Anyone who has actively asked not to be contacted is removed before the campaign even begins. The result is a list of people who have not said no, which is a better starting point for every channel.

An example from a coaching centre

Say a JEE coaching centre runs a voice campaign in March and a WhatsApp broadcast in April to a similar list. During the March campaign, a few hundred parents ask not to be contacted again, some by replying on WhatsApp, some by telling a counsellor on the phone. When the April list is uploaded, those numbers are already flagged and left out of the promotional send. Nobody on the team had to cross-check two spreadsheets, and none of those parents hear from the centre again unless they reach out themselves.

The centre also saves the cost of messages that would only have annoyed people, and its WhatsApp number avoids a wave of blocks.

Good habits we recommend

• Make the opt-out easy to find, not hidden at the bottom
• Collect clear opt-in on forms and at the front desk; see our guide on WhatsApp and RCS opt-in best practices
• Do not re-upload old lists that include people who opted out
• Check your WhatsApp quality rating after big sends
