WhatsApp Links vs Verified WhatsApp Contacts

Why it matters: Inspect the destination host and the phone parameter or path. Normalize only a valid international number, preserve the original source and reject malformed values. Do not assume every phone number in a company record is WhatsApp-enabled. A generic messaging button can also point to a shared business account rather than the named decision-maker.

• Keep published WhatsApp evidence separate from ordinary phones.
• Do not guess missing country codes.
• Review redirect and shortened links cautiously.

Why it matters: A link may have been published for customer support. That does not automatically authorize a campaign unrelated to that purpose. A successful account check only establishes a limited technical observation at a point in time. Confirm the intended relationship and follow applicable platform and legal requirements before sending, especially when importing third-party datasets.

• Do not label extracted numbers as opted in.
• Keep ownership evidence with the contact.
• Respect opt-outs and blocking signals.

Why it matters: A connected sending session is not a guarantee that each recipient can receive a message. Verify readiness before enqueueing and preserve recipient-level failures. If the sending session disconnects, stop new attempts and show a recoverable state rather than slowly failing an entire list. Reconnection should not replay recipients whose messages already succeeded.

• Check genuine session readiness.
• Record actual recipient outcomes.
• Do not use sender rotation to bypass restrictions.
