Picture this: you connect your email to an AI assistant expecting it to maybe surface one stray gift card, tops. Instead it comes back and tells you there’s $800 in airline credit sitting in your account, credit you have zero memory of ever earning. That’s exactly what happened to u/Professional-Rest138 over on r/PromptEngineering, and I’ll admit, when I read the post, my first thought was “okay, I need to check my own inbox right now.”
The original poster connected Gmail to Claude, asked it to dig through years of email for anything owed to them, and the AI turned up $800 in American Airlines credit that doesn’t expire until 2028, plus a handful of restaurant gift cards from old birthday presents. Not a scam recovery trick, not a hack. Just years of forgotten emails getting read properly for the first time, the kind of digging most of us keep meaning to do on a rainy Sunday and never actually get around to.
Why This Actually Matters 💸
Turns out this isn’t some rare fluke. The poster cites a stat that 43% of people are sitting on at least one unused gift card or credit right now, averaging $244 in value. Companies aren’t out here scamming anyone. They just know a credit email from eighteen months ago gets buried under four thousand others and never gets opened again. Your inbox is basically a lost and found nobody’s checked in years, and the stuff piling up in there isn’t just gift cards either. Think flight vouchers from a canceled trip two years back, refunds a company promised and you forgot to follow up on, a deposit from an apartment you moved out of, or a rebate you mailed in and never tracked. Every one of those has a paper trail sitting in your search history, it just needs someone patient enough to actually read it.
How To Do It Yourself 🔍
Setup takes one time, and it works on Claude’s free plan, worth noting since the poster says ChatGPT’s version of this generally needs a paid plan. That alone makes this worth twenty minutes of your evening.
- In Claude, click your profile in the bottom left, then “Customize,” then “Connectors,” then find and connect Gmail. It can only read your email, it can’t send or delete anything, so there’s no risk of it going rogue on your inbox. This is a one-time setup, so once it’s connected you can rerun this search anytime new credits pile up.
- Paste this exact prompt:
Search my entire Gmail history for any money I am owed or have never used. Include gift cards, e-gift cards, store credit, airline and travel credits, vouchers, refunds that were promised, deposits, rebates, settlement payouts and unused promo credit on any account. For each one give me the company, the amount, the date of the email, the code or reference number, the expiry date if there is one, and a direct link to the email. Sort by highest value first and add up the total. Do not invent anything, if you’re unsure about an amount, say so.
Give it a couple of minutes. It’s actually reading years of email, so don’t close the tab early just because nothing’s happened in the first thirty seconds. Depending on how old your inbox is, this can genuinely take a few minutes to churn through everything, and that’s normal, not a sign it’s stuck.
- That list isn’t spendable money yet. Some codes are already used or expired, so run this second prompt to verify:
Now go to each of these companies’ websites and actually check whether each credit is still valid and how much is left. I’ll log in wherever you need me to. Come back with three lists: confirmed still good with the real balance, expired or already used, and the ones you couldn’t verify.
You’ll likely hit a login screen on at least one site, that’s expected. Log in yourself, then tell Claude to keep going from there. This step is really the difference between a fun list and actual usable money, so don’t skip it just because step two already felt satisfying.
Tips & Tricks 🧠
- Never type a real password directly into the chat. Log into sites yourself when Claude hits a wall, then hand control back.
- Don’t panic if the total comes back at zero. That just means your record-keeping habits are better than most people’s, not that the method failed.
- Most people land somewhere between fifty and a few hundred dollars found. The floor is nothing, the ceiling is apparently $800 in airline credit, so the math on twenty minutes of your time works out pretty well either way.
- Worth doing this quarterly, not just once. New credits and refunds get buried in your inbox every few months, so a repeat run tends to keep turning up small wins.
- The original poster keeps a running doc of prompts like this one for everyday tasks, so if this search scratches an itch, there’s likely more where it came from in the original thread.
Give It A Shot ⚓
Worst case, you spend twenty minutes and confirm you’re already on top of things. Best case, you find your own version of that $800 credit sitting quietly in an email you forgot existed.

Frequently Asked Questions
Q: Is it really safe to connect my Gmail to Claude?
Yes , Claude’s Gmail connector uses read-only access through OAuth (the same authentication system your phone uses for third-party apps). Claude can’t send emails, delete messages, or modify anything. Your password isn’t stored, and the search only reads your own email history, never shared with other users or training data.
Q: Where does the 43% statistic come from?
That number isn’t cited to a specific source in the post, so treat it as an estimate rather than a hard stat. The real value isn’t the statistic , it’s actually running the search yourself and checking what’s actually sitting in your email. The validation step (confirming each credit with the company) is where you discover real money.
Q: Does this work on the free plan?
Yes. Claude’s Gmail connector is available on the free tier, which is one advantage over ChatGPT (which usually requires a paid plan for email integration). No subscription needed to find your credits.
Q: How accurate is Claude at finding all my credits and gift cards?
Claude is pretty reliable at scanning through years of emails and spotting obvious gift cards and store credits, but it can miss things , especially credits buried in promotional emails or sent in unusual formats. That’s why the validation step is essential: checking each company’s website to confirm the credit is still active and see the actual balance left. Think of Claude as a thorough helper, not a guarantee of 100% accuracy.
Q: How long does this actually take?
The Gmail search takes a couple of minutes (depending on how many years of email you have), and don’t close the tab early or you’ll lose progress. The validation step , where Claude checks each company’s website , takes longer if you have many credits to verify, especially if some require logging into accounts.
