How to Send Google Workspace Encrypted Emails with Paubox?

Paubox Outbound Gateway is a solution designed to integrate with email services, allowing users to send encrypted emails in compliance with regulations like HIPAA. When integrating with Google Workspace (formerly known as G Suite), Paubox provides a seamless way to ensure that emails sent from your Google Workspace account are fully encrypted.

Here’s a detailed step-by-step guide for setting up the Paubox outbound gateway with Google Workspace. This process involves configuring your Google Workspace account and your Domain’s DNS settings to work with Paubox.

What Do You Need Before Setup?

Before setting up Google Workspace with Paubox, you will need three things.

  1. Domain name (learn how to setup domain on Google Workspace)
  2. Paubox trial or paid account
  3. Google Workspace subscription

During Paubox signup, you will get an outbound gateway value which we will later use. Keep reading.

1. Update Your Domain Records

In order to send Google Workspace encrypted emails through Paubox, you will need to first set up your domain records.

Before you proceed further, make sure that you do not have any TXT record that has “v=spf1 -all” Value in it. If you have one, modify it with “v=spf1 -all“.

If you do not have such a TXT record, follow the guide.

1. Go to your Domain control panel and click the “Manage” button.
