Included Templates

Website Widget

Add an opt-in widget to your website — a floating button or slide-in form that asks visitors: 'Get updates on WhatsApp?' with a phone number input and opt-in checkbox. Conversion rate: 3-5% of website visitors.

Checkout Flow

Add a WhatsApp opt-in checkbox during checkout: 'Send me order updates on WhatsApp'. Pre-check the box (with clear disclosure) for maximum opt-in. Conversion rate: 40-60% of orders.

Email CTA

Add a WhatsApp opt-in CTA in your email footer or dedicated email campaign: 'Get faster support on WhatsApp'. Link to a click-to-chat URL. Conversion rate: 2-4% of email recipients.

Social Media Bio Link

Add a WhatsApp click-to-chat link in your Instagram, Facebook, and Twitter bios. Use a URL like wa.me/yourNumber?text=Hi to start conversations. Conversion rate: Varies by followers.

QR Code

Print WhatsApp QR codes on packaging, receipts, business cards, and in-store signage. Scanning the QR code opens WhatsApp with a pre-filled opt-in message. Conversion rate: 5-10% of scans.

SMS Keyword

Ask customers to text a keyword (e.g., 'JOIN') to a short code to opt in for WhatsApp updates. The SMS triggers a WhatsApp opt-in confirmation message. Conversion rate: 15-20% of SMS recipients.

IVR Opt-In

During phone calls, offer WhatsApp as an option: 'Press 1 to receive updates on WhatsApp.' The IVR captures the caller's number and sends a WhatsApp opt-in confirmation. Conversion rate: 20-30% of callers.

In-App Prompt

Show an in-app prompt or notification asking users to enable WhatsApp notifications: 'Get real-time updates on WhatsApp?' with a one-tap opt-in button. Conversion rate: 10-15% of active users.

Tips for Best Results

  • Always include clear disclosure — state what types of messages the customer will receive
  • Send a welcome message within 5 minutes of opt-in to confirm and set expectations
  • Make unsubscribing easy — 'Reply STOP to unsubscribe' must work at all times
  • Checkout flow opt-in has the highest conversion rate — prioritise this method
  • A/B test opt-in copy — 'Get order updates on WhatsApp' converts better than 'Subscribe to WhatsApp'
  • Track opt-in source to understand which methods drive the most engaged subscribers

Frequently Asked Questions

Is opt-in mandatory for WhatsApp Business API?
Yes. Meta requires businesses to collect explicit opt-in before sending template messages (marketing, utility, or authentication). Violations can result in account restrictions.
Can I pre-check the opt-in checkbox?
Pre-checking is allowed if you provide clear disclosure about the types of messages the customer will receive. However, an unchecked box with clear context often yields higher-quality opt-ins.
How do I handle opt-outs?
Lodgestory automatically processes STOP messages and removes the contact from your WhatsApp audience. You can also configure custom opt-out keywords.
What does the opt-in disclosure need to include?
Disclosure must state: your business name, the types of messages (order updates, promotions, support), how to opt out (Reply STOP), and a link to your privacy policy.
Can I re-engage users who opted out?
You should not send WhatsApp messages to users who opted out. You can use other channels (Email, SMS) to invite them to re-subscribe with a clear opt-in link.
