Every receipt in one place your assistant can search.
Order confirmations, invoices, flight changes, renewal notices. Send them to an Echos address and ask questions instead of scrolling.
Receipts are the mail you never read and always need later. What did that flight cost. When does the subscription renew. Did the refund actually go through.
Use an Echos address at checkout, or forward the confirmations there. Echos reads text out of PDF attachments, including scanned ones, so an invoice that arrived as an image is still searchable.
Then the question is just a question. "What did I spend at Amazon in August." "Find the confirmation number for the Lisbon flight." "Which of these renew before the end of the quarter."
At tax time you have a mailbox that only ever held receipts, which is a better starting point than a search operator and forty minutes.
Use it at your next checkout.
