Secure Email flow via Paubox Portal

This document explains the behaviour when the custoemr receives a Secure Email via Paubox POrtal. This happens in two situations:

1. When the client require portal delivery (for highest security with sensitive documents)

2. When customer’s email system doesn't support modern encryption TLS 1.2+ (some older systems need this extra layer)

Here how it works:

Customer will receive a standard email with a "View Message" link. The actual message content isn't shown in your inbox—it's kept safe in Paubox secure portal. You'll see only a simple link to access it.

Click "View Message" and customer will be asked to confirm who you are using one of these methods:

• Text a code to your phone, or

• Email a code to your address

Choose whichever is easiest for you. This verification happens just once per device—after that, you're all set.

Once verified, customer can view your complete secure message with all attachments. Everything is encrypted and protected while you view it.

1. Email Sample - The user will get below email(the email will be white-labelled). The email doesn’t show the message but a link.

2. How to view Email - User clicks on the View Message, they will get a screen to enter their Phone# or email (depending on the preference) for 2 Factor Authentication. Please note that the authentication will happen only once per device.

3. View email after authentication - Once the code is confirmed, User will be able to view the message in the secure Paubox portal.
