Encrypted in transit
TLS across every connection, client to server to database.
Correctable business messages
Send a secure message link for an invoice, quotation, event update or important instruction. If something changes, update the same link and keep a clear record of every correction.

The recipient experience
Afterword updates the secure page behind your message link. It does not rewrite an email already delivered to somebody's inbox. When you correct a sent message, the current version is marked and the earlier version remains in the correction record.
SAME LINK — WATCH IT UPDATE
Invoice #4021
Please pay to account 0123456789.
Built for business information that can change after sending. Afterword keeps the current message easy to reach without hiding that a correction happened.
Invoice correction
Correct a reference, total or instruction while retaining a timestamped record.
Quotation update
Keep a forwarded quotation linked to its current, clearly identified version.
Event change
Update a venue or time at the same link and notify email recipients.
Recipients can see when the message was changed and when the latest correction happened.
Earlier sent versions are retained to support accountability.
Unexpected payment changes should be confirmed directly using a trusted contact method.
Security

Hashed with scrypt, unique salt per account.
Timestamped, and cannot be altered or deleted.
Gate a sensitive message beyond the link itself.
Card details never touch our servers.
Then permanently locked, no exceptions.
