Opt-ins and staying on Meta's good side
Quality rating drops when people block or report you. Consent and a working opt-out are the practical defence.
Meta scores the number. A low quality rating cuts the number of people you can message. The usual cause is sending to people who did not ask.
Collect a specific yes
"Message me on WhatsApp about my order" is specific. A pre-ticked box is not. Store when and how they agreed, in a custom field if you need the audit.
Honour stop immediately
Zyptos skips opted-out contacts in every broadcast. Agents can also mark a chat as opted out from the inbox. Do not import a purchased list. There is no path back from that.
We do not promise a green tick. Meta decides display-name and official-business approval.
