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.

Paubox works with Google Workspace, Microsoft 365, and Microsoft Exchange. Be sure your email host provides a business associate agreement.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
