WhatsApp opt-in and Indian compliance

WhatsApp requires opt-in before you send anyone a business message, and India's Digital Personal Data Protection Act adds its own consent and erasure obligations on top. In practice the two point the same way: collect consent explicitly, record when and how you got it, make opting out easy, and honour it immediately.

What counts as valid opt-in

The person must have taken a clear, affirmative action knowing they would receive WhatsApp messages from your business by name. A pre-ticked box is not consent. Neither is a phone number collected for delivery being reused for marketing.

  • A checkbox at checkout or on a form, unticked by default, naming WhatsApp and your business
  • The customer messaging you first
  • Scanning your WhatsApp QR code or tapping your wa.me link
  • An explicit in-person or written agreement you can evidence

What the DPDP Act adds

Broadly, four obligations relevant to messaging.

  • Consent must be free, specific, informed and unambiguous
  • People can withdraw consent as easily as they gave it
  • People can request erasure of their personal data
  • You should hold only what you actually need, and not indefinitely

How ConneXus handles it

The mechanics are built in rather than left to your discipline.

  • STOP and UNSUBSCRIBE flagged automatically and honoured across WhatsApp, SMS and email
  • Per-channel opt-out, so someone can leave marketing without losing order updates
  • Contact erasure that anonymises the record while retaining what tax law requires
  • Audit logs with personal data scrubbed before storage
  • Tenant credentials and secrets encrypted at rest

Frequently asked questions

Do I need opt-in for order updates?

Transactional messages about a purchase the customer made are generally expected by the customer, but WhatsApp still requires opt-in for business messaging. Collect it at checkout — it costs nothing and removes the ambiguity.

Is a purchased contact list ever acceptable?

No. It breaches WhatsApp's terms, fails DPDP consent requirements, and reliably gets numbers restricted.

What happens when someone replies STOP?

They are flagged immediately and excluded from future marketing across WhatsApp, SMS and email, without anyone having to action it manually.
