Five steps to migrate your business to Proton

Step 1. Sign up

Choose your plan, select the number of users you need, and check out with a payment card or PayPal. You’ll need to create a username and password for your administrator (admin) account.

If you run a large business and would like to explore our Enterprise plan, contact our contact our sales team(new window).

Step 2. Set up your domain

Connect your custom domain (or domains) so you can receive email@yourcompany with Proton Mail. You’ll need to have access to your DNS records to set up your custom domain.

Step 3. Create your organization

Create an organization to enable multiple users to have email addresses using your custom domain (@yourcompanyname). You’ll need to set an organization password, which ensures that only you (and other admins) have access to your data.

Step 4. Set up users   

Set up users with Proton Accounts and email addresses. Assign users’ admin rights, allocate storage, set privacy levels, and create a catch-all address for your domain.

Step 5. Migrate your data to Proton

Use our Easy Switch app to migrate your existing emails, contacts, and calendar from Gmail, Outlook, Yahoo Mail, or any other email provider that uses IMAP. Easy Switch works in the background so you can use your computer as normal while your emails and data are encrypted and imported into your Proton Account.

Once your migration is complete, you can learn more about how to make the most of your new Proton plan at our Proton for Business FAQs(new window) or Support(new window) page.
