Frequently asked questions
-
What makes Paubox better than other solutions?
Paubox is designed for ease-of-use, both for senders and recipients alike. Paubox eliminates unnecessary friction while also maintaining compliance. Portal logins, plugins and app downloads are a thing of the past with Paubox.
-
Which email hosts work with Paubox?
Paubox works with Google Workspace, Microsoft 365, and Microsoft Exchange. Be sure your email host provides a business associate agreement.
-
Can I keep my email address?
Yes! If you have a business email address that ends in your business domain (like @yourbusiness.com), you can keep it. Paubox integrates with Google Workspace, Microsoft 365 and Microsoft Exchange.
-
If I have a Google Workspace or Microsoft 365, why do I need Paubox?
Google and Microsoft will both sign business associate agreements in connection with their email platforms, but those agreements only cover emails within their servers and at rest. Paubox ensures your emails are secure in transit outside of their servers.
-
How do my recipients know my email is encrypted?
Every email includes a message in the footer identifying that Paubox secured the email. Additionally, recipients can look at the header and see that each relay was secured with up to 256-bit AES encryption.
-
What if I don't have a business email address?
If you use a consumer email provider, like @gmail.com or @yahoo.com, then you need a business email in order to be HIPAA compliant. Consumer solutions are not compliant and should not be used.
-
What happens if the recipient’s email system doesn’t support TLS encryption?
If a recipient's mail server is not setup to handle TLS encryption, Paubox automatically uploads the email (including attachments) to our secure webapp. In order for the recipient to view your message, it's only one additional click.
-
Can I use my smartphone with Paubox?
Yes, you can use your smartphone and your favorite email apps.
Paubox can also easily be setup on tablets and smartwatches with no proprietary apps or downloads needed.
-
Are my attachments enrypted?
Yes, all attachments are encrypted. Paubox supports attachments up to 50MB.
-
Are replies to my emails encrypted?
Yes. By default, replies to your emails are encrypted in transit.
-
Are there any fees for a business associate agreement?
No. All customers receive a business associate agreement at no additional charge.
-
What is a sender?
A sender is defined as one email address such as you@yourcompany.com. Aliases and email groups are not counted.
