Sound familiar?

The job, before and after this agent.

What it feels like today

  • “We run a great webinar and then send everyone the same bland thank-you a week later.”
  • “Questions people asked live never get a proper answer.”
  • “Sales has no idea which attendees were actually interested.”

What you get with the agent

  • Every new row in your attendee sheet read as it arrives.
  • Attendees get a thank-you that answers their own questions, using only the webinar details you write.
  • No-shows get the replay and a line on what was covered.
  • Every person saved in HubSpot with a note on attendance, questions and interest; hot attendees posted to your Slack sales channel.
  • Emails wait for your approval by default; switch review off and only pricing, contract or complaint questions wait.

Before

Three days after the webinar, someone exports the list, sends one generic replay email, and the attendee who asked about pricing for a five-person team never hears back.

After

The same afternoon, that attendee gets a reply to their exact question, their HubSpot contact notes the interest, and a rep sees them in Slack as a hot attendee.

How it works

The whole workflow, step by step.

Paste your webinar attendee export (or let your registration form write to a Google Sheet): each new row is read by AI. Attendees get a thank-you that answers the questions they asked, using only the webinar details you write; no-shows get the replay and one line on what was covered. Every person is saved in HubSpot (created or updated by email) with a note on attendance and questions, and hot attendees by your rules are posted to your Slack sales channel. Emails wait for approval by default; switch review off and only pricing, contract or complaint questions wait. It doesn't connect to Zoom or webinar platforms directly.

Example run

What goes in, and what comes out.

Example with fictional data

Comes in

New sheet row: Hannah at Acme Foods, attended 52 minutes, asked whether it works with her accounting software and what it costs for a five-person finance team.

The agent produces

Draft thank-you answering the integration question from your webinar details, and pointing pricing to a call (pricing questions always wait). HubSpot contact updated with an attendance note. Posted to #sales as a hot attendee. Waiting for approval.

What you need

Everything it takes to run it.

About 15 minutes from purchase to live. A checklist above the canvas takes you through each step.

Plan

Included in Enterprise; on other paid plans it's $79 once. Agents run live on paid plans, from Basic ($39/mo).

Your AI key

Apps

Checklist

  • A paid plan (agents run live on paid plans).
  • An AI provider key (Settings → AI Providers).
  • Google Sheets, HubSpot and Slack, connected in Settings → Integrations.
  • Your attendee export (or a registration form) in a Google Sheet.

Setup, about 15 minutes

  1. Connect your AI provider. The AI steps run on your own key (OpenAI, Anthropic, Google and more). Add one in Settings → AI Providers.
  2. Connect Google Sheets. Connect the Google account that can open your attendee sheet (Settings → Integrations → Google Sheets).
  3. Connect HubSpot. Connect your HubSpot account (Settings → Integrations → HubSpot).
  4. Connect Slack. Connect the Slack workspace your sales team uses (Settings → Integrations → Slack).
  5. Pick the attendee sheet. Open the trigger, pick your Google account, paste the spreadsheet link and the tab name.
  6. Describe the webinar. Open “Write the matching follow-up” and replace the placeholder with the webinar details, links, offer and hot rules.
  7. Pick your HubSpot account. Open “Save the contact in HubSpot” and “Note the webinar on the contact” and pick your account.
  8. Pick the Slack account and channel. Open “Alert sales about a hot attendee” and pick your account and channel. Invite the app to private channels first (/invite @Fluxo Flow).
  9. Add your inbox. Open “Email the follow-up” and enter the address replies should go to.
  10. Test it with Dry Run. Press Dry Run: the agent runs on sample data with no messages sent and nothing written to your apps.
  11. Switch the trigger on. Open the trigger and click “Activate app trigger”: new rows are picked up on your plan's schedule interval. Only rows added after activation are followed up.

FAQ

Questions about Webinar Follow-Up.

Does it connect to Zoom or my webinar platform?

No. Export the attendee report, or have your registration form write to a Google Sheet; each new row gets followed up.

What if it answers a question wrong?

It answers only from the webinar details you write and leaves anything else for a teammate. By default every email waits for your approval.

Which apps do I need?

Google Sheets, HubSpot and Slack. Setup takes about 15 minutes. Rows without an email address are skipped.

Is it worth the price?

A one-time price that never renews, against hand-writing follow-ups for every attendee. Live runs need a paid plan and your own AI provider key.

Can it send without review?

Yes. Change “REVIEW EVERY EMAIL: yes” to “no”: routine emails are then sent at once, and only questions about pricing, contracts, security or complaints wait for approval.

Is this a subscription?

No. Webinar Follow-Up is a one-time purchase of $79 per workspace and never renews. The Enterprise plan includes it at no extra cost. Running it live needs a paid plan (from Basic ($39/mo)), and your AI provider bills you directly for usage.

Can I test it before it touches real data?

Yes. Once it's set up in your workspace, Dry Run plays every step on sample data with simulated AI and app calls: nothing is sent and nothing in your apps changes. Switch the trigger on only when you're happy.
