Intercom outbound message with a Sume avatar clip: email or in-app

Can an Intercom message carry a video?

Intercom's create-message page lists three message types: in_app, email and whatsapp. The body supports HTML and plain text, and email has a subject. The page documents no video or attachment field, so the practical route is a link, or an image that links to the clip, in the body.

What do I put in the body?

A thumbnail image and a text link to the clip's video_url. Render the avatar clip first, then compose the message with the stored URL. Sume media URLs are public HTTPS, so any email client or browser can open them. Avoid sending the job's status URL; that needs your API key.

For a 20 second reply to a trial user, a plus-tier clip with no product image costs 20 x $0.245 = $4.90, so reserve it for moments that matter, like a welcome or a win-back.

How do I keep the send step simple?

Do the Sume work in a step before the send. Submit with mode: "webhook", and when job.completed arrives, call Intercom with the URL. The send step then never waits on a render. The webhook signature has to be verified first; see the webhook docs.

If you wait inline instead, sync mode waits at most 30 seconds, and a longer job returns an envelope you must keep polling.
