Send travel checklists and welcome-back messages

n8n

Overview

Built an n8n workflow for a problem most travel agencies have: forgetting to check on customers.

Workflow

Suggested implementation: Build an n8n workflow to automate customer follow-ups for travel agencies. The system should scan trip sheets daily to trigger a WhatsApp checklist three days before departure and a welcome-back message one day after return. A human operator must review the trip data and approve message templates before automation is enabled to ensure accuracy and prevent duplicate sends.

Reported result

The source does not report any measured outcomes, success rates, or specific business impacts. It is unknown whether the workflow was successfully deployed or if it reduced customer churn. A measurable acceptance check would be to verify that zero duplicate messages were sent to the same customer ID over a 30-day test period.

Human role

The original post does not say how a person stayed involved.

Limitations

Prerequisites include access to a structured trip sheet (e.g., Google Sheets) and a WhatsApp Business API account. Integration uncertainty exists regarding how the system identifies 'return' dates versus 'departure' dates without manual tagging. Proposed advice: Implement strict deduplication logic and require human approval for any new message templates to avoid spamming customers.

Try it

Act as an automation engineer. I need to set up an n8n workflow for a travel agency to automate customer check-ins. Inputs: - Trip data source: [replaceable: Google Sheet URL or CSV file path] containing columns for Customer Name, Phone Number, Departure Date, and Return Date. - Messaging channel: [replaceable: WhatsApp Business API credentials or Twilio SID]. - Output location: [replaceable: n8n workflow JSON export or specific folder path]. Steps: 1. Create a daily trigger node that reads the trip data. 2. Filter for customers whose Departure Date is exactly 3 days from today. Send a predefined checklist via WhatsApp. 3. Filter for customers whose Return Date is exactly 1 day ago. Send a 'Welcome back' message. 4. Implement a deduplication check using a database or sheet to ensure no customer receives the same message type twice. 5. Perform a dry run with 5 sample records. Show me the simulated output logs. 6. Wait for my confirmation before enabling the live WhatsApp nodes. Quality Measure: The workflow must not send duplicate messages. Success is defined by the dry run correctly identifying the 3-day and 1-day windows without errors. If the trip data lacks clear Return Dates, ask me for clarification before proceeding.
