What is WhatsApp Business API?

The WhatsApp Business API allows businesses to send automated messages, set up chatbots, and manage customer conversations at scale — unlike the basic WhatsApp Business app.

Can I send bulk messages on WhatsApp?

Yes — via the Business API with Meta-approved message templates. Unapproved bulk messaging violates WhatsApp's policies and risks account ban.

Which markets work best for WhatsApp marketing?

India, UAE, UK, Brazil, and Southeast Asia have extremely high WhatsApp adoption rates. It is particularly effective for B2C and local services in these regions.

How is WhatsApp marketing different from email?

WhatsApp has 90%+ open rates vs email's 20–30%. Messages are read within minutes on average. It is better for time-sensitive updates but requires explicit opt-in.

Do clients need to opt in to receive WhatsApp messages?

Yes — explicit opt-in is required. We implement opt-in collection at form submission, checkout, and in email sequences.
