1. Staff check in Outlook
IT adds the pane once. They stay on the open message. People without Outlook use the live check or attach the saved original to check@signet7.io. They do not check junk.
Enterprise and business
A company can prove the email before anyone acts.
Law, title, construction, payroll, and finance already live in email. Signet7 is the check and the record. Recipients do not need to install anything. Your people keep writing in the mail they already use. This brochure site does not take passwords.

No recipient install

Checkout is not live yet
Setup
Four moves. No theater.
2. Named work emails
One program on an office computer, on the emails that can move money, jobs, or clients. Ordinary mail stays quiet. Not a thousand installs.
3. IT can push Outlook
Then the check happens on the open message. People do not leave mail. Sideload works today. Org-wide push is a Microsoft 365 admin step. Not AppSource.
4. List this address when you seal outbound
So outsiders can look up whether that key is still yours. Public lookup shows DNS keys and hosted listings after enroll. Checkout is not live.
Technical specification
The spec is for IT. The decision is for the desk.
This page will not dump commands or source. If your IT lead needs the sheet, it is already written.
What this is not
A pretty site is not the product.
You get
- A check on a sealed message
- A record you control and can produce later
- A live recipient check with no install
- A company account
You do not get
- A password wall on this brochure
- A promise that a pass is the same as safe
- Live checkout until the owner turns it on
- A public staff console on this domain
