n8n After-Hours Form Routing: Gmail + Telegram Alerts

Route website form alerts after hours with automatic Gmail + Telegram notifications

This n8n workflow receives your website form submissions via a webhook, validates the payload, immediately acknowledges the visitor (HTTP 200/400), and then intelligently routes alerts based on business hours—sending on-call alerts through Gmail and Telegram after hours or for urgent/emergency requests.

What this workflow does

• Receives form submissions via an n8n webhook using a POST request from your website form.
• Cleans and validates inputs (name, email, phone, message, and an optional urgency field). Invalid payloads are rejected.
• Acknowledges instantly:
  • HTTP 200 with a confirmation message for valid submissions.
  • HTTP 400 with validation errors for invalid submissions.
• Checks business hours using your configured timezone and weekly opening hours.
• Routes notifications**:
  • After hours or emergency/urgent: sends an on-call email via Gmail, then sends a Telegram alert.
  • During business hours: sends a daytime notification email via Gmail only.

Use cases

• Your SaaS site captures leads via a contact form—after-hours requests should alert the on-call team fast.
• Emergency support forms (marked urgent) should bypass business hours and trigger both email and Telegram alerts.
• Operations teams want immediate visitor acknowledgement while the workflow handles routing in the background.

Technical details

• Nodes / features: webhook, if, code, gmail, telegram, and a sticky note.
• Time logic: business-hours checking against your timezone and opening schedule.
• Gmail integration: Gmail OAuth2; configure the destination inbox (replace ONCALL_EMAIL@example.com).
• Telegram integration: create a Telegram bot, add the n8n Telegram credential, and set REPLACE_WITH_YOUR_CHAT_ID.

Setup (quick)

• Point your website form to the workflow’s Production webhook endpoint.
• Update the timezone and weekly opening hours in the business-hours step.
