Turn Receipt Emails Into a Recurring Spend Map

Keep billing mail findable, map merchants to recent charges, and hand clean evidence to a separate subscription-review workflow.

Premise

Before reducing recurring spend, you need a trustworthy inventory. A narrow inbox assistant classifies receipts and billing mail, maps merchants to recent amounts, and leaves negotiation or cancellation to a separate workflow.

Setup

  1. Connect the billing inbox and define receipt, billing, personal, and noise labels.
  2. Review examples from each category.
  3. Build a merchant map from verified messages.
  4. Feed that map—not raw guesses—to the subscription-review process.

Boundaries

  • Files and labels only; it does not negotiate, unsubscribe, or cancel.
  • Receipt-like mail is never classified as noise.
  • Suspicious attachments from unknown senders remain unopened.

Archive obvious noise only under the rules I approve. If a message could be a receipt, preserve it and mark it for review. Report daily filing totals and bills you could not identify.

Do not negotiate, cancel, unsubscribe, delete receipt mail, or send messages. Do not open invoice attachments from unfamiliar senders. If two brands may share a billing parent, keep them separate until I confirm the relationship.

Prompt

Organize my inbox so billing records and receipts are easy to audit. Apply my approved labels for receipts, billing, personal mail, and noise, and maintain a merchant map containing label, latest receipt date, amount when explicitly shown, and evidence link.
