The brilliance of this is the use of email receipts as the data source. There's so many services that use Yodlee (and/or the the Quicken-style "direct connect" method) to fetch your transactions but they all eventually fall over:

- your credentials change

- your credentials require MFA authentication

- your credentials require a password reset or security question/answer intervention

- the bank, Yodlee, or the service lose track of the transaction offset and you get duplicate transactions or missing transactions

- the service doesn't transmit all available metadata
