auto launch chat bot from email signature link

Has anyone embedded a link within an email block signature that will open up a chat bot?

I have someone who wants to place a link inside their email signature 'chat with us here' and he wants this to launch the bot.

Apart from building a separate landing page for the bot to reside in and launch within, is there a URL that will launch the bot on his site? I reckon the easiest thing is to populate the url with his website and auto-launch the bot within it.

You can’t create a “Voiceflow-only” URL that runs the chat on its own – the widget always lives inside a page you host – but you can load that page and programmatically pop the widget open as soon as it finishes loading.

Embed the normal web-chat snippet on the page you’ll link to:```html<script>(function(d,t){var v=d.createElement(t),s=d.getElementsByTagName(t)[0];v.onload=function(){ window.voiceflow.chat.load({ verify: { projectID: 'YOUR_PROJECT_ID' }, url: 'https://general-runtime.voiceflow.com', versionID: 'production' }).then(() => { // open the widget immediately window.voiceflow.chat.open(); });};v.src='https://cdn.voiceflow.com/widget/bundle.mjs';v.type='text/javascript';s.parentNode.insertBefore(v,s);})(document,'script');</script>```
Point the email-signature link to that page. Example: `https://your-site.com/chat`.
(Optional) Only auto-open when the visitor comes from the email by adding a query flag:• Email link → `https://your-site.com/?openchat=true` • JS check:```jsconst params = new URLSearchParams(window.location.search);if (params.get('openchat') === 'true') {window.voiceflow.chat.open();}```

The key call is window.voiceflow.chat.open()window.voiceflow.chat.open() (part of the Custom Triggers API), which programmatically opens the widget once chat.load()chat.load() resolves.
