Automate SMS Follow-Ups with Typeform, Twilio & Google Sheets

Transform your lead response time from hours to seconds with this intelligent SMS automation workflow that captures Typeform submissions, sends instant welcome messages via Twilio, and automatically follows up with non-responders using Google Sheets tracking.

What this workflow does

This three-branch n8n automation creates a complete SMS follow-up system. When customers submit your Typeform, they instantly receive a personalized welcome SMS through Twilio while their details are logged to Google Sheets with timestamp and nudge tracking. The workflow monitors Twilio 24/7 for replies, automatically marking responders and stopping future contact. A smart scheduler runs every 6 hours, identifying non-responders and sending up to 2 strategic follow-up nudges at 24-hour and 48-hour intervals before stopping permanently.

Use cases

• Lead qualification: Capture prospects via Typeform and instantly engage them while interest is hot
• Service bookings: Follow up on consultation requests or appointment inquiries automatically
• Customer onboarding: Guide new signups through next steps with timely SMS reminders
• Event registration: Ensure attendees receive important updates and respond to confirmations
• Sales pipeline: Recover leads that would otherwise go cold with systematic follow-up

Why this matters

Studies show leads contacted within 5 minutes are 9x more likely to convert. This workflow transforms your response time from hours or days to under 10 seconds, ensuring 100% follow-up consistency while eliminating 5-15 minutes of manual work per lead. Instead of high lead drop-off rates, you'll automatically recover revenue from non-responders.
