Signet7 is the cryptographic seal and check for high-stakes email.
Check an important email before you act. Signet7 checks two facts: whether the words still match the seal, and whether that sender is listed. Recipients never install. Checkout is not live.
Save the original. Open the live check. You get a signed file you can produce later. It does not mean the email is safe to pay. The same evidence can gate actions proposed by people or AI agents before irreversible steps.
What you do
Check a message. List the work email. Keep the file.
List the work email

Keep the file
The seal is on the message. That file is the record. You can show later that the words still matched.
