Who receives it — audience, consent & frequency limits

Every WhatsApp campaign builds its recipient list through the same set of rules: consent, the suppression list, frequency limits, and de-duplication. This is why the number sent is often lower than your segment size — and that's by design, to protect your number's health.

Consent (opt-in)

A contact must have opted in to WhatsApp before you can send them a marketing template. A contact opts in when they:

• message your number first (inbound messages auto-opt-in);
• are imported with a WhatsApp opt-in column set to yes;
• are marked opted-in in bulk on /admin/clients, or via the one-click attestation in the campaign wizard.

An explicit opt-out always wins — an inbound message won't re-opt-in someone who previously sent STOP.

STOP and START

If a recipient replies STOP (or similar), HexaFloww immediately opts them out and adds them to the WhatsApp suppression list. START opts them back in. These are checked before auto-replies and AI, so an opt-out is always honoured.

Suppression list

The suppression list (/admin/suppression) is a global do-not-send registry, per channel. Any number on the WhatsApp suppression list is excluded from every send, no exceptions. See Consent, opt-in & the suppression list.

Frequency limits

To avoid fatiguing your audience, HexaFloww enforces self-imposed limits on marketing messages (utility and authentication are exempt). Set them at /admin/whatsapp/settings/compliance:

• Minimum gap between marketing messages to the same contact — default 24 hours.
• Maximum per week — default 3.

Contacts over either limit appear as Frequency-capped by you in the wizard's skip breakdown. For a deliberate extra send, the wizard has an include anyway checkbox that overrides your own caps (it still reports how many were overridden).

De-duplication

If the same phone number appears more than once in your audience (for example two contact records), only one message is sent and the rest show as Duplicate numbers.
