Drain any mailbox

Outlook, Gmail, Yahoo, or any IMAP account — pulled into one secure vault.

Verified before deletion

Every email is hash-checked in the vault before anything leaves your inbox.

Find anything, fast

Search by name, sender, or the words inside emails and attachments.

How it works

Full inbox to safe archive, in four steps.

1

Connect your mailbox

Sign in on your provider — Seshat never sees your password. Revoke access any time.

2

Everything moves in

Every email and attachment is copied into a private, encrypted vault by year and month.

3

Every email is verified

Seshat confirms each item is stored byte-for-byte before anything moves on.

4

You free up space

Choose how far back to clear. Originals stay in your vault to search or download.

Your inbox
Reclaims space once every message is safely stored.
The vault
Encrypted, byte-exact originals — searchable for 7 years.
Your computer
Download any email or a full year as a .zip, any time.
Security

Security you can prove.

Every claim below maps to a control you can audit — not a promise you have to take on faith.

Encrypted end to end

AES-256 at rest and TLS in transit, in storage isolated from everything else.

Byte-exact originals

Defensible for audits, e-discovery, and the full 7-year retention window.

Verified before deletion

Every message is hash-checked in the vault before it ever leaves your inbox.

Identity-gated access

Your archive requires account sign-in with two-factor authentication — no anonymous access, ever.

Contained to your account

You only ever see your own files; every request re-checks ownership.

Audited & retained

Every sign-in, download, and deletion is logged, with legal hold when needed.
