Accounting firm: deadline mail reaches an accountant

The setup

Partner Hugo fans clients@ out to six accountants. Each owns their client list and replies from their own address.

How the mail flows

1. A client sends missing receipts on March 28th with an April deadline.
2. All six accountants hold the identical documents within minutes.
3. The owning accountant files on time instead of discovering the mail April 2nd.
4. clients@ keeps the per-client paper trail for review and HMRC/IRS queries.

Why Sinka fits here

• Seasonal preparers get real copies in January, revoked in May.
• Spreadsheets and scans arrive byte-identical — no retyped figures.
• Cover works because anyone can see any client's latest mail.

Watch out for

• Client lists must be explicit, or two accountants start the same return.
• Retention rules apply to every copy — set the same deletion policy on all six inboxes.
