Creating an Organization (ProtonMail for Business)

After you have added a Custom domain to your account, you will have the ability to create an Organization. This will allow you to have multiple users using your custom domain for their email addresses.

To create an Organization, visit the Addresses/Users tab of the Settings of your account.

Creating an Organization in Settings

Select Enable Multi-User Support to create your first Organization. When you do so, you will be prompted to pick a name for your Organization. This name for private internal use only, it will not be seen outside of your account.

Setting up your organization with ProtonMail

Upon picking your Organization’s name, you will be provided with an opportunity to select your Organization’s key strength. This key will be used to encrypt all data in your user’s accounts (exception with private accounts), providing you access to the data while preventing ProtonMail from accessing this data.

Keys for your employees

Your organization password is what protects your key from ProtonMail. It is critical that you do not lose or forget this password as it is the way you will gain access to your organization in the future. Lose of this password will result in the organization being un-editable.

Organization Administrator Password

Now that your organization password and keys have been set, it is time to allocate storage space to your admin’s account. The storage space available to your organization is determined by the level of storage you have selected in your Protonmail plan. You can increase it in the future if you need to. You will have the ability to select the storage amount each user has access to. At this step, you will be deciding how much space to allocate to the administrators account. This storage will be used for the administrator’s email contents, email is the only use of this storage at this time.

Allocate Storage Settings

You should now see an Organization appearing at the top of your Addresses/User tab in your Settings.

Complete Organization in Settings

Once you have verified you can setup the Users of your Organization.

    So when I add members to my organization, does that cost extra for each email account? So let’s say I have 4 employees. How much am I paying for us 5?
    If it’s included, how many people are included which each plan?

  2. ProtonMail Support

    The Professional plan comes with 1 user included. To be able to add additional users, you will need to upgrade your plan to include extra users. For more information, you can read our ProtonMail Professional Plan FAQ at the following link:

    Could you help me understand this? I have an organization and I have 5 users in total but we also have a custom domain that we want to setup on Protonmail. I have tried to understand the total cost it will take for me to set this up but the information is scattered in your support questions so I need your help to understand it better.

    What will be the total cost of having a custom domain, an organization set up and adding in total 5 users (including me)?
