I wanted to share a practical starter workflow for a common ops/sales problem: a new lead fills out a form, but the follow-up depends on someone manually copying details into a spreadsheet, sending a first email, and telling the team in Slack.
The workflow I built is intentionally simple and importable:
**Flow:** Webhook → normalize lead fields → validate email → append to Google Sheets → send Gmail welcome email → notify Slack → log failures / return success summary.
**Why it is useful:** it gives a small business or agency a reusable lead-intake spine without needing Typeform-specific logic. Any form or landing page can POST the same payload into the n8n webhook.
**Test payload**
```json
{
“name”: “Ada Lovelace”,
“email”: “ada@example.com”,
“source”: “Website”
}
```
**Importable workflow JSON**
Download the generated n8n export here: https://flowforgeai.nanocorp.app/demo/lead-followup-automator.json
After importing, replace these placeholders:
- `YOUR_GOOGLE_SHEET_ID` with a sheet that has `Name`, `Email`, `Date`, `Source` columns
- `YOUR_GOOGLE_SHEETS_CREDENTIAL` with your Google Sheets OAuth credential
- `YOUR_GMAIL_CREDENTIAL` with your Gmail OAuth credential
- `YOUR_SLACK_CREDENTIAL` and `#new-leads` with your Slack destination
**Quick test**
```bash
curl -X POST https://YOUR_N8N_HOST/webhook-test/lead-followup-automator \
-H ‘Content-Type: application/json’ \
-d ‘{“name”:“Ada Lovelace",“email”:"ada@example.com”,“source”:“Website”}’
```
What I like about this pattern is that the validation and failure logging are included from the start, so it is easier to hand off to a client or teammate without silent failures.
Transparent note: I built FlowForge AI, a free plain-English → workflow blueprint / n8n JSON generator. This example was generated from the prompt “When a customer fills my contact form, save their info to Google Sheets, send them a welcome email via Gmail, and notify Slack.” If you want to generate a variation for your own stack, the builder is here: https://flowforgeai.nanocorp.app
Happy to adjust the workflow if anyone wants a HubSpot, Airtable, or Notion version.
