Frequently Asked Questions
What is Auth-Email?
Auth-Email is an OAuth proxy 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.
How does Auth-Email work?
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.
What are some use cases for Auth-Email?
Auth-Email is ideal for:
- Managing account authorization for multiple email accounts with ease
- Accessing email from clients that don't support OAuth – for example, service desks, CRM platforms, scan to email, printers, and older apps
- Accessing the same account from multiple clients without managing OAuth separately for each one
- Tracking account access and usage
Which email providers are supported?
Auth-Email supports a wide range of email providers, including Gmail, Google Workspace, Microsoft 365, 21Vianet, Exchange Online, Outlook, Windows Live Mail, Hotmail, Yahoo, AOL, Comcast, Yandex, VK Mail and more.
What are the setup details for my Auth-Email account
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.
Is my data secure with Auth-Email?
Yes – we prioritize your security and privacy. When you authorize your account, your OAuth tokens are securely encrypted with a password you choose. We don't store your password, and your encrypted data cannot be accessed by us.
Will there be any issues with deliverability?
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.
Are there any message limits?
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.
Can I manage multiple email accounts?
Yes, Auth-Email allows you to manage multiple email accounts from a single dashboard (including shared or delegated accounts).
The number of accounts that can be added depends on your plan:
- Starter: 1 account
- Personal: 5 accounts
- Pro: 25 accounts
