Using American Express Encrypted Email


Receiving Encrypted Email

How do I read an encrypted email?

The American Express encrypted email will arrive in your email inbox like any other email message. It will consist of an email message with an html attachment that includes the embedded encrypted content. The format of the email and placement of the html attachment will vary slightly depending on your email client.

Open the html attachment. The method you use to open the attachment will vary depending on your email client. If using web-based email, right click on the html attachment and select Open, Open in New Window, or Open in New Tab depending on your preference. Other email clients may require you to single or double-click on the attachment. The attachment should open into a browser window and display a graphic resembling an envelope. Click on the Read Message button in the envelope to initiate the first-time registration process. The Read Messgae button is not enabled when the attachment is previewed within the email client. It will only be enabled if the attachment is opened in a browser window.

The first time you receive an encrypted email from American Express, you will be prompted to perform a first-time registration process. The registration process will involve selecting a unique password and password recovery question for your account. You will then receive a verification email with a one-time link to complete the registration process and present you with the decrypted email content in your secure browser window. This one-time verification email link will expire after 120 minutes. If you do not complete the registration process within that timeframe, you will have to start the registration process over by opening the html attachment in the original encrypted message.

Subsequent encrypted emails sent from American Express will also arrive as normal in your inbox and contain the html attachment with the encrypted email content. Open the html attachment using the same method previously and click on the Read Message button. Your browser will be redirected to the secure login pages in the tool. Sign in using your unique password selected during the registration process. When you have entered your password in correctly, the encrypted email will be decrypted and presented to you in your secure browser window.

How do I access attachments sent to me?

All secure attachments are contained within a single Zero Download Messenger package to enable easy access. To open the attached files, click on the [view] button next to the attachment names - a new browser window will open to enable you to access the attachment.

What are signatures and what does it mean if the signature is valid with a green check mark?

Every secure email is signed by the sender of the message to ensure authenticity of the sender and data integrity of the message. The green check mark indicates that the signature associated with this email is valid and the message can be trusted.

What are signatures and what does it mean if the signature is invalid with a red X mark?

Every secure email message is signed by the sender of the message to ensure authenticity of the sender and data integrity of the message. The red X mark means that the signature associated with this message is not valid and the message may have been forged. Please contact the sender if this condition occurs.

You may get a copy of the secure email that you have composed sent back to your email address. By default, this is enabled by clicking the "Copy Me" link next to the "To" field.

Using Message Receipts

How do I know that recipients were able to decrypt the secure message?

You can request that a receipt is sent to your email address when each recipient decrypts the secure message that you are composing. To receive receipts, click the Request Receipt link. If you do not want a receipt when the message is decrypted, click the Remove Receipt link. The Request Receipt link is only available if the administrator has enabled it.
