Frequently Asked Questions
Auth-Email is an OAuth relay that handles all aspects of OAuth authentication for your email accounts, allowing you to use standard password authentication with any email client, app, device, service or script. We proxy your connections transparently so you can forget about OAuth and focus on your email.
Auth-Email handles the OAuth step for you. You authorize your accounts in Auth-Email’s dashboard, and then use Auth-Email’s server settings in your email client to access your accounts using a password you choose.
Auth-Email is ideal for:
- Accessing email from clients that don’t support OAuth – for example, service desks, CRM platforms, scan to email, printers, and older apps or devices
- Managing account authorization for multiple email accounts in one place
- Accessing the same account from more than one client without managing OAuth separately for each one
- Tracking account access and usage
Auth-Email supports a wide range of email providers, including Gmail, Google Workspace, Microsoft 365, 21Vianet, GCC High, Exchange Online, Outlook, Windows Live Mail, Hotmail, Yahoo, AOL, Yandex, VK Mail, and more.
Enterprise accounts managed by Microsoft 365 or Google Workspace are fully compatible with Auth-Email.
We also support ISP-provided accounts, including AT&T, Cox, Comcast, Sky, Rogers and others managed by Yahoo.
Our support pages have all the details you'll need to set up your accounts (including servers and ports), plus walkthroughs for advanced features like custom OAuth client flows, account delegation, legacy connection protocols, and add-ins to modify mail server behavior.
Yes – we prioritize your security and privacy. When you authorize your account, the access details are securely encrypted with a password you choose. We don’t store your password, and your email account cannot be accessed by us.

No! Unlike SMTP forwarding services, Auth-Email uses your email provider’s original servers, so you can rest assured that your messages will reach their destination.
As a bonus, this also means you don’t have to worry about DNS configuration, SPF, DKIM or any of the other complex and error-prone requirements for modern email sending.
No. Unlike other services, Auth-Email does not track or limit the number of messages. All plans come with unlimited messages!
Instead, we give a generous monthly bandwidth allowance for each plan. The Starter plan comes with 1 GB, while the Personal plan has 5 GB. The Pro plan includes 50 GB data per month.
