Frequently asked questions

What is a custom email domain?: A custom email domain is a personalized email address that uses your business name instead of the name of your email provider — for example, yourname@yourbusiness.com instead of yourname@protonmail.com.
How does a custom email domain benefit my business?: A custom email domain boosts your brand’s credibility and professionalism. It ensures consistency across all communications, helps build customer trust, and makes your business appear more established. Additionally, it allows you to create tailored email addresses for different teams or purposes — such as sales@yourbusiness.com — enhancing organization and security.
How does Proton Mail keep my emails secure?: Proton Mail uses end-to-end encryption — an advanced security measure that ensures only the sender and the recipient can read the contents of an email.
Unlike other email providers, Proton doesn't (and can’t) access your emails for advertising, data mining, or surveillance. Your privacy is our priority, and with end-to-end encryption your messages remain confidential, safe, and secure.
What if I already have a professional email address?: If you already have a professional email address with Gmail, Yahoo, or Outlook, you can import your custom domain, messages, calendars, and contacts to Proton Mail in just a few moments with Easy Switch. Your data will automatically be encrypted as they arrive at Proton.
You can also switch to Proton Mail and let your team continue using the apps they know. Proton Mail Bridge works with Outlook, Apple Mail, Thunderbird, and other IMAP/SMTP clients.
