The envelope talks
From, Reply-To, Return-Path, Message-ID, the Received chain and X-* fields name the sender, their server, and — via the Date — their timezone.
Anonymous email mediation
Broker the deal. Hide the sender.
3way.email seats a mediator between two parties. Every message is stripped of names, headers, signatures, and metadata before it reaches the other side — so a negotiation can happen over email without either party ever learning who they're talking to.
Why email is the hard part
Chat leaks in one place. Email leaks in a dozen.
A chat message is basically its text. An email carries a paper trail — routing, timezones, signatures, quoted history, file metadata. Anonymizing it means scrubbing every one of these surfaces, not just the words.
A real domain is a fingerprint
One look at @meridian-capital.com and the counterparty knows the firm. Every address is rewritten to a neutral relay alias; the real domain never crosses.
The footer is a business card
Name, title, company, phone, office address, legal disclaimer — the block most people never think about is the richest identity leak in the message.
Replies drag the past along
Hit reply and the entire prior thread rides underneath — re-exposing names and addresses you already cleaned three messages ago.
Files carry hidden authors
DOCX and PDF author fields, image EXIF and GPS, tracked changes and margin comments all travel inside the file, invisible in the preview.
The message can phone home
Tracking pixels and remote content beacon a party's identity back on open. And beyond the explicit, there are implicit tells: a shared memory, a place both recognize, a distinctive turn of phrase.
How it works
Follow one email, A → Mediator → B.
There is no direct line between the two parties. Every message takes the same path through the mediator, in both directions.
Onboard separately
Each party is set up on their own, and each receives a private relay alias. Neither one ever sees the other's real address.
Send to the relay
The sender emails the mediator's alias — never the counterparty. As far as their outbox is concerned, they're writing to party-b@relay.3way.email.
Sanitize
Headers are rewritten, signature, quoted history and attachment metadata are stripped, and identifying content is redacted before a human ever reads it.
Mediate
The mediator reviews the cleaned email and can hold it, annotate it, steer the terms, or release it. Nothing moves without a decision.
Deliver anonymized
The other side receives it from a neutral alias. Replies travel the very same path in reverse — sanitized again on the way back.
Capture the deal
Terms and a full audit trail are recorded for the mediator — a complete history that never crosses the anonymity wall between the two sides.
The moderation stack
Three layers. Nothing identifying crosses the wall.
Each layer catches what the one before it can miss. Machines handle scale and pattern; a person handles judgment.
Catch the obvious, at scale
Models flag names, contacts, entities and header or PII patterns automatically — every address, phone number and routing field, on every message.
Catch the implicit
Contextual review sanitizes signatures, collapses quoted threads and scrubs attachment metadata — and flags the subtle tells a keyword match would sail right past, suggesting rewrites in place.
Make the call
A person makes the judgment calls, brokers the terms, and controls every single release between the two sides. Nothing crosses without them.
Defense in depth — a leak has to slip past a model, an AI reviewer, and a human before it ever reaches the other party.
Use cases
When the terms matter and the names can't.
Explore a deal quietly
Test appetite and price with a counterparty without either side's interest — or identity — leaking to the market.
Settle before you name names
Move toward a settlement figure through a mediator while both parties stay anonymous until terms are actually agreed.
Compete on the number alone
Run anonymous, sealed-style bidding where offers are judged on merit, not on who sent them.
Source without tipping your hand
Negotiate sensitive supply terms without revealing which buyer — or which incumbent — is at the table.
Raise it safely
Let an employee surface a concern to leadership through a mediator, with identity protected on the way in and out.
Approach discreetly
Open a conversation with a passive candidate — or a company — before either side commits their name to it.
Features
Everything the wall is made of.
@
Relay aliases
Each party gets a stable, neutral address like party-a@relay.3way.email. Real addresses and domains never appear.
H
Header stripping
From, Reply-To, Return-Path, Message-ID, Received chains, X-* fields and the timezone in Date are rewritten or removed.
§
Signature & quoted-thread scrubbing
Footers and trailing reply history are detected and collapsed, so the business card and the past never ride along.
◫
Attachment-metadata sanitizing
DOCX/PDF author fields, image EXIF, and tracked changes or comments are cleared before a file is passed on.

Mediator audit trail
Every message, edit and release is logged for the mediator — a full record of the deal that stays on their side of the wall.
⏸
Hold & release
Nothing auto-forwards. The mediator holds each message, annotates or steers it, and releases it deliberately.
Architecture
No party ever holds another party's real address.
The mediator is the only shared point of contact. Party A and Party B each speak to a relay alias and nothing else — there is no code path where one side's real From, domain, or header reaches the other.
Wall invariant: every message is A → Mediator → B, sanitized at the center, in both directions — no exceptions.
Party A
party-a@relay.3way.email
mediator
Party B
party-b@relay.3way.email
