Zapier → trigger on new form submission (native integrations for most form tools; webhook fallback otherwise).
Spreadsheet + worksheet + column mapping. Include submission timestamp from the form.
Channel #new-leads. Message includes name, need and link to the sheet row context.
Bold the one-line need, keep it under five lines. Alert ≠ report — it should trigger a reply, not a read.
Submit the real form once. Verify row AND Slack. Then turn both Zaps on and stop watching.
