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 encrypted?

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.

Frequently asked questions

How does Paubox Email API work?
Paubox Email API is a cloud-based SMTP provider that acts as an email delivery engine, allowing you to send email without the cost and complexity of maintaining your own email servers. Paubox Email API manages the technical details of email delivery, like infrastructure scaling, ISP outreach, reputation monitoring, and real-time analytics.
How does the free plan work?
Once you verify your account, you can send 300 emails a month at no charge. If you need to send more than that, you can easily upgrade to a paid plan.
Do I have to sign up for Paubox Email API and Paubox Marketing separately?
Yes. If you want to use the Paubox Email API in conjunction with your Paubox Marketing account, you will need to purchase the plans separately. But once you sign up, you can use the same account to send via the Paubox Email API or through Paubox Marketing.
How do you measure the number of emails I send?
Every time you send one email to one recipient, it’s counted as one email for your Paubox Email API plan. This occurs whether the email is ultimately deferred or sent to spam by the inbox provider. Also note that emails you send via Paubox Marketing will be counted separately from any emails you send via the Paubox Email API.
What happens if I go over my plan?
If you send more emails than your plan allows within a given billing period, you will be charged a small overage fee on a per email basis. Any overage fees are added to a new invoice.
Why do I need to verify my account?
We require all of our customers to verify their accounts. This helps to safeguard your account and maintain deliverability for you and all of our customers.
