Which email providers work with automatic receipt forwarding?

Gmail, Outlook, Yahoo Mail, and iCloud Mail all support auto-forwarding rules that work with Graiden. Gmail is the easiest to set up because it supports both full auto-forwarding and filtered forwarding (only forwarding emails matching certain criteria). Outlook and Yahoo have similar filter-based forwarding. iCloud Mail supports forwarding rules through the web interface at icloud.com.

How accurate is AI extraction from email receipts?

Graiden's AI extraction accuracy is above 95% for common receipt formats from major merchants, payment apps, and subscription services. The AI identifies the merchant name, transaction amount, date, and category. Unusual or poorly formatted receipts may occasionally need manual correction, but this is rare for mainstream services.

What happens if a purchase doesn't generate an email receipt?

Purchases that don't generate email receipts -- like some cash transactions or in-store purchases where you decline a digital receipt -- won't be tracked automatically. You can manually add these transactions in Graiden. For most people using cards and digital payments, email receipts cover 70-90% of spending without manual input.

How to Track Expenses Automatically from Email Receipts

Name: Graiden
Author: Graiden

Every purchase you make generates an email receipt -- from your bank, from the merchant, from your payment app. Graiden turns those receipts into organized, categorized expense data automatically. Set up auto-forwarding in your email once, and every future transaction gets extracted, categorized, and logged without any manual work.

This guide covers exactly how it works, how to set it up, and what it can and can't capture.

What Generates Email Receipts?

More of your spending produces email receipts than you might realize. Here's a breakdown:

Online Shopping

Every online purchase sends an order confirmation and receipt email. Amazon, Shopee, Lazada, ASOS, iHerb -- any e-commerce purchase generates at least one receipt email, usually two (order confirmation and shipping notification with the charged amount).

Credit and Debit Card Transactions

Most banks offer transaction alert emails. If you enable these in your banking app, every card swipe generates an email with the merchant, amount, and timestamp. This is one of the highest-coverage sources because it captures virtually every card transaction, including in-store purchases.

Subscriptions and Recurring Bills

Netflix, Spotify, YouTube Premium, cloud hosting, SaaS tools, insurance, phone bills -- every subscription service sends a monthly billing receipt. These are some of the easiest expenses to forget about, making automatic tracking particularly valuable.

Food Delivery and Ride-Hailing

GrabFood, Foodpanda, Deliveroo, Uber Eats, Grab, Gojek -- every order and every trip generates a detailed receipt email with itemized costs, fees, and tips.

Digital Wallets and Payment Apps

Apple Pay, Google Pay, GrabPay, and other payment apps send transaction confirmations for many purchases. Coverage varies by merchant, but it's improving steadily as more retailers adopt digital receipts.

How AI Extraction Works

When a receipt email arrives at your Graiden forwarding address, here's what happens behind the scenes:

Email parsing: The system reads the email's HTML content, plain text body, and metadata (sender, subject line, timestamp).
Merchant identification: AI identifies the merchant from the sender address, email body, and receipt formatting. "noreply@grab.com" with an order summary is recognized as a Grab transaction.
Amount extraction: The total charged amount is extracted from the receipt. For itemized receipts, both the total and individual items can be parsed.
Date determination: The transaction date is pulled from the receipt content, not just the email send time (which can differ by hours or days for some merchants).
Category assignment: Based on the merchant, the transaction is automatically categorized -- groceries, dining, transport, entertainment, subscriptions, shopping, etc.
Deduplication: If you receive multiple emails for the same transaction (order confirmation + shipping + delivery), the system identifies these as the same purchase and avoids double-counting.

The entire process takes seconds. By the time you check your Graiden dashboard, the transaction is already there, categorized and logged.

Setup Guide: Auto-Forwarding by Email Provider

The setup is a one-time process. Once configured, it runs forever without any action from you.

Gmail

Gmail offers the most flexible forwarding options. You can forward all emails to Graiden, or create a filter that only forwards receipts. The filter approach is cleaner -- set up a filter matching common receipt keywords ("receipt," "order confirmation," "payment," "invoice") or specific sender addresses, then set the action to "Forward to" your Graiden address. Full instructions at our email forwarding guide.

Outlook / Hotmail

Outlook supports rules-based forwarding. Create a new rule in Settings > Mail > Rules, define conditions (sender contains specific domains, subject contains "receipt"), and set the action to forward to your Graiden address.

Yahoo Mail

Yahoo supports filter-based forwarding through Settings > More Settings > Filters. Create filters matching receipt emails and set them to forward to your Graiden address.

iCloud Mail

iCloud Mail supports forwarding rules through the web interface at icloud.com. Go to Mail Settings > Rules and create rules to forward receipt emails. Note that iCloud's rule options are more limited than Gmail's, so you may want to use broader forwarding criteria.

Apple Pay Tracking via iOS Shortcuts

Apple Pay transactions don't always generate merchant receipt emails, but Apple Wallet does record every transaction. You can bridge this gap with an iOS Shortcut:

Create a new Shortcut triggered by a new transaction in Apple Wallet
Set the action to compose and send an email to your Graiden forwarding address
Include the transaction amount, merchant name, and date in the email body
Set it to send automatically without confirmation

This captures Apple Pay transactions that wouldn't otherwise generate forwarded receipts, significantly improving coverage for iPhone users who use Apple Pay frequently.

What Email Receipt Tracking Captures vs. Misses

Being realistic about coverage is important. Here's the honest breakdown:

High coverage (95%+ of transactions captured):

Online shopping
Subscriptions and recurring bills
Food delivery orders
Ride-hailing trips

Medium coverage (60-80% captured):

In-store card payments (depends on whether you've enabled bank transaction alerts)
Digital wallet payments (depends on the merchant and wallet provider)

Low coverage (manual entry needed):

Cash transactions
Bank transfers to individuals (PayNow, Venmo, etc. -- not all send receipt emails)
Some in-store purchases where no digital receipt is offered

For the average person who primarily uses cards and digital payments, the total coverage lands between 70-90%. The remaining transactions can be added manually if you want complete records, or simply accepted as a small gap if you prefer zero effort.

Privacy and Security

A fair question: is forwarding receipt emails to a third party safe?

Here's what's shared: the content of receipt emails. This includes merchant names, amounts, dates, and sometimes itemized purchases. Here's what's not shared: your bank credentials, account numbers, login tokens, or any access to your bank account.

Compared to bank-linked expense trackers that require your banking login through services like Plaid, email receipt forwarding shares significantly less sensitive data. A receipt email contains roughly the same information as a paper receipt you'd throw in the trash. Your bank login, on the other hand, provides access to your entire transaction history, account balances, and in some cases the ability to initiate transfers.

Graiden processes receipt emails with the same encryption standards as any modern email service. Emails are encrypted in transit (TLS) and at rest. Receipt data is stored in your private account and never shared with third parties or used for advertising.

Getting Started

The setup is genuinely fast. Sign up at graiden.app, get your forwarding address, set up one email filter, and you're done. Your first tracked expenses will appear within hours as new receipt emails come in. No bank linking, no manual entry, no ongoing maintenance. Just automated expense tracking from the receipts you're already receiving.
