Value Proposition: Clearly communicate the benefits of opting in (e.g., "Get exclusive deals," "Receive instant order updates," "Access priority support").
Pop-ups/Banners: Use non-intrusive website pop-ups or banners that lead to your WhatsApp opt-in form or directly to a "Click-to-WhatsApp" chat.
During Online Purchases/Checkout:
Integrate an opt-in checkbox during the e-commerce checkout process. This is ideal for transactional messages (order confirmations, shipping updates).
Example: "Receive order updates via WhatsApp." (checkbox)
Interactive QR Codes (Physical & Digital):
Physical Locations: Place QR codes in whatsapp number list your physical store, on product packaging, receipts, flyers, or business cards.
Digital Locations: Embed QR codes in emails, social media posts, or on your website.
Action: When scanned, the QR code should initiate a WhatsApp chat with a pre-filled message (e.g., "Hi, I want to subscribe to updates from [Your Business Name]"). The first message from the user constitutes an opt-in for that specific conversation. You can then use the chat to obtain more explicit consent for specific message types.
