Send post-event session digest emails with WayinVideo, OpenAI and Gmail

Fill in a simple form with your event name, session recording URLs, and attendee emails — the workflow handles everything else. It sends each session video to [WayinVideo](https://wayin.ai/api/) AI, which generates a written summary and key highlights for each one. OpenAI then uses those summaries to write a professional HTML digest email, which Gmail sends to every attendee automatically. Built for event organisers, marketing teams, and agencies who want to follow up with attendees after a webinar, summit, or conference without writing a single word manually.

What This Workflow Does

- Parallel session summarisation — Submits all three session recordings to WayinVideo at the same time, so you don't wait for each one to finish before the next starts - AI-written digest email — Passes all three session summaries to OpenAI GPT-4o-mini, which writes a complete, formatted HTML email with key takeaways and recording links for each session - Automatic attendee delivery — Sends the finished digest email to every email address you entered in the form — no copy-paste, no manual sending - Structured HTML output — The email arrives with proper formatting, session headers, bullet points, and "Watch Recording" buttons — ready to read in any email client - Form-based job submission — Anyone on your team can trigger the workflow using a web form — no access to n8n required - Three sessions in one run — Handles up to three recording URLs per event in a single workflow execution - Custom sender name — The email is sent with the sender name you provide in the form, so it arrives looking like it came from your team
