n8n Twilio SMS Quote Follow-Up Workflow with Webhook

Turn new quote leads into scheduled Twilio SMS follow-ups—automatically

With this n8n Twilio SMS Quote Follow-Up Workflow with Webhook, every new quote can trigger a timed SMS chase: the workflow waits, checks whether the customer replied via Twilio, sends personalized nudges only if needed, and alerts the business owner when the customer responds or when the follow-up closes.

What this workflow does

• Receives quote details via webhook: A POST request sends customer phone, name, job, amount, and an optional quote URL. The workflow responds immediately with a JSON response.
• Builds personalized nudge messages: It normalizes the incoming data, generates three nudges, and calculates follow-up times in your configured time zone.
• Notifies the owner that the chase has started: If the phone number and required settings are valid, it sends an SMS to the owner’s cell via Twilio.
• Waits, checks, and nudges: For nudge #1, #2, and #3, it waits until the next scheduled time, then calls the Twilio Messages API to check whether the customer replied since the chase started.
• Stops on reply: As soon as an inbound reply is detected, the workflow stops and immediately texts the owner.
• Closes after nudge #3: If no reply arrives after the third nudge, it sends an SMS to the owner indicating the chase is closed.

Use cases

• Service businesses that want instant, consistent follow-up after a quote submission.
• SaaS teams automating lead nurturing without manual chasing.
• Automation engineers integrating quote capture with n8n and Twilio SMS reply detection.
