Bill emails into due-date reminders

Utility and phone bills arrive by email with a due date buried somewhere inside. This finds the date and puts a reminder in your calendar.

InputBill emails from known senders
ToolsGmail filter, Zapier, an AI step, Google Calendar
TimeSetup about 20 minutes.

Download it

The n8n file has three nodes (trigger, AI step, output) plus a read-me note. We check that its JSON structure is valid, but we haven't run every file in a live n8n instance, so test it with sample data before you switch it on.

Steps

  1. Trigger: email from your list of billers.
  2. AI step extracts the amount and due date.
  3. Create an all-day calendar event 3 days before the due date.

The prompt

From this bill email, return JSON {biller, amount, currency, due_date YYYY-MM-DD}. Null if not stated. Email: {{body}}

Sample run

Example input (written for illustration)
Electricity bill email: 'Amount due €54.20 by 28 October 2026'
Example output (shows the format, not a real log)
{"biller":"Electricity","amount":54.20,"currency":"EUR","due_date":"2026-10-28"}

Where it breaks

  • Direct debits. If it's paid automatically, filter it out or you'll get pointless reminders.
  • Anything customer-facing or money-related. Keep a human approval step until you've watched a few dozen runs and trust it.

Tool names and pricing change often, so check each tool's current docs before you build. Times on this page are estimates, not measurements.
