EMAIL INTEGRATION · YAHOO MAIL

The inbox you've had forever,finally keeping the books.

Plenty of real businesses run out of a Yahoo inbox that predates the business itself. CashFish connects over IMAP with an app password and starts turning that mail into expense records within minutes.

01One inbox, two lives

It was a personal address.
Then it became the business.

Nobody decided this. The address on the first order form was simply the address you already had, and it never got replaced.

2009

An inbox older than the company

Fifteen years of mail in one account: school newsletters, flight confirmations, and somewhere in the middle, this quarter's shipping costs.

The charges too small to chase

A shipping label here, a listing fee there. Each one is too small to be worth writing down, and together they are the difference between a good month and a flat one.

APR

The annual plan that renewed itself

The confirmation email mentioned the new price. It arrived on a Thursday, between two deliveries and a newsletter, and nobody read that far.

SUN

The Sunday spent adding it up

A notebook, the search box, and the growing certainty that some of it is missing. The total you end up with is the total you can find.

The record was always in there. What it never had was a shape.

02What comes in

Everything financial,
nothing forwarded by hand.

No rules to set up, no address to forward to. CashFish connects to the mailbox as it stands and reads what has been arriving there all along.

Multiple mailboxes can feed one workspace, so a Yahoo account and a Gmail account sit side by side. Duplicate detection works across all of them — an invoice that lands in two inboxes is still recorded once.

The IMAP connection is read-only, so CashFish pulls documents into your workspace and never writes to, sends from, or reorganizes your Yahoo account.

03Six messages, one March week

What the inbox
was already holding.

Ordinary mail from an ordinary week: what arrived, what CashFish read off it, and the record it turned into. The last one waits, because two receipts looked like the same $9.05.

Held — possible duplicate

Read-only over IMAP. Nothing was sent from the account, no message was moved between folders, nothing was marked read and nothing was deleted.

04What changes

The small money
finally shows up.

Nothing dramatic happens. The scattered small charges gather into one running record, the repeats identify themselves, and the week finally has a number.

Every extraction waits in a review queue. Approve it, recategorize it or dismiss it — nothing counts because a machine said so.

Side-hustle costs stop leaking

Shipping labels, design tools, the phone bill — small charges scattered across months of mail add up to real money. CashFish gathers them into one running record you can actually total.

Recurring charges show their pattern

Renewal emails repeat, and CashFish notices. Recurring senders are flagged, upcoming renewals get reminders, and a re-sent receipt never becomes a second expense.

A weekly picture, drawn from mail

Nothing counts until you say so — extractions wait in a review queue. Once approved, they add up to a week-by-week view of what the inbox has been paying for.

05How to begin

Three steps,
and your password stays put.

An app password is a separate, scoped credential Yahoo issues for exactly this. Revoke it and the connection ends — nothing else you use is affected.

Generate an app password

In Yahoo's Account Security settings, create an app password for CashFish. Your real Yahoo password never leaves Yahoo.

Paste it into CashFish

Enter your Yahoo address and the app password. CashFish connects over IMAP with read-only behavior — it fetches mail and changes nothing.

Confirm the first batch

The backfill covers 150 days. Skim the review queue, approve what's right, and CashFish keeps checking for new documents every 5 minutes.

Any IMAP mailbox connects the same way. Bank sync across 12,000+ institutions is read-only and opens on Growth, along with store and payment connections like Stripe and WooCommerce; QuickBooks and Xero import one way into CashFish and are never written back to.

08Straight answers

What people ask
before connecting Yahoo Mail.

App passwords are Yahoo's supported route for third-party mail apps. Your real password stays with Yahoo, and the app password is scoped and disposable — revoke it from Yahoo Account Security at any time and the connection dies without you changing anything else.
