CertEmail Email Notary and Timestamping service
The CertEmail Email notary service lets you Timestamp and certify your email and other documents.
CertEmail offers the worlds only Email Notary service which works
for everyone without sender or recipient needing any additional
Our Notarized email enables you to indisputably prove the sending (and
subsequent opening) time of your email. Your proof-of-sending and
proof-of-opening certificates are court admissible legal documents
which are independently verifiable, tamper/forgery resistant, and
remain effective without the need for any "trusted third party".
Here are some common uses for Notarized (Certified) Email:-
Prove in a court of law that you sent an email when you did. You get an irrefutable
receipt. Your recipient gets the email with an attached and
verifiable digital proof of posting certificate.
Proof the email you sent has not been subsequently changed, forged,
or tampered with. Your attached certificate verifies not only the
date, time, and recipient, but also the email contents and headers
as well. If anything gets changed, the certificate can be used to
Proof the email you sent was opened. Our digitally signed
proof-of-opening receipts record when Email is rendered for display
on a computer screen, including additional evidence to verify that
the email was observed by a human recipient (as opposed to being
read by a computer program alone), in an approximate physical
location using recorded email or web-browser software at a specific
point in time.
Other proof. Because Notarized Email is time-stamped and digitally
signed (tamper and forgery resistant) you can use them for all
kinds of other purposes.
You can email your thoughts to yourself if you want lasting evidence to prove you thought of an idea before someone else did.
You can email bets to your friends to establish beyond reproach that your authentic bet has not been backdated and was placed before the outcome was known.
You can hold competitions and use the earliest issued certificate to select a winner.
You can email your documents or assignments to yourself to prove later you had/created them at a specific time, and (if required) to guarantee they have not been altered since or prove that you have legal ownership.
