Live-chat boxes get abandoned the moment a visitor leaves your site — WhatsApp conversations don't. Once someone messages you, you can follow up, answer later and even re-engage them with broadcasts. Businesses typically see far higher response rates from WhatsApp chats than from contact forms.
How to install
- Any website: paste the snippet just before the closing
</body>tag. - WordPress: use a "custom HTML" footer widget or a header/footer-code plugin.
