Webinar Onboarding and Verification

Source reviewed Updated 2026-07-07

Validates new webinar signups in real time, generates a personalized PDF welcome kit with AI.

What it does

You instantly validate new webinar signups to filter out fake registrations while generating a personalized PDF welcome kit for each attendee. This process automatically stores verified data in your spreadsheet and sends the customized materials via email, ensuring high-quality first impressions without manual work.

Step by step

  1. Parse the incoming webhook payload to extract email and interest fields.
  2. Send a verification request to an email validation API endpoint.
  3. Append verified rows to the specified Google Sheet using the Sheets API.
  4. Attach the generated PDF file to an outgoing Gmail message.

Where the LLM does the work

  • Generate a personalized welcome message that references specific attendee interests from the signup data.
  • Draft concise, professional text for the PDF welcome kit summary section.
  • Create a unique subject line for each email based on the recipient's profile to improve open rates.

Watch out for

LLM outputs can vary in length which may break fixed-width PDF layouts so add a character limit filter before generation.
Gmail API quotas reset daily so batch send emails during off-peak hours to prevent hitting the 500-email daily cap.
Personalization tokens might fail if user data is missing so add a fallback message for incomplete profiles.

## Reference implementation
https://n8n.io/workflows/11730 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions

Can I use a different Email than Gmail?

Yes. Gmail is only the example email in this recipe. The same flow works with Brevo, KlickTipp, Lemlist and Mailchimp. Swap the email connection and keep the rest of the setup as written.

Want this running in your business?

This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.

Who it's for

Built for marketers who'd rather brief an agent than start from a blank doc.

Founders and execs get the same output without having to ask someone else to run it.
