  • Emails from a custom account appear more professional than emails from an address.
  • A custom domain offers maximum flexibility when it comes to hosting.
  • You can use your own email domain with iCloud and also with any other mail platform.

Connect iCloud Mail to your custom domain: Step-by-step guide

To be able to send iCloud emails via a custom domain, you first of all need your own domain. If you already have your own individual Internet address, you are one step ahead at this point. Otherwise, the first step is to purchase a domain from your trusted provider.

Once you have a personal domain, simply follow the instructions below to link the iCloud+ email service with the custom domain.

Step 1: Sign into iCloud Mail

The first step is to sign into the iCloud Mail service with your account. Since the feature is currently only available in the beta version, use the iCloud Beta page for this.

Step 2: Go into the settings for “Custom Email Domain”

On the iCloud login screen, press the “Account Settings” button and then access the menu for linking iCloud and a custom domain by pressing the “Manage” button in the “Custom Email Domain” section:

Step 3: Select the type of email account and specify the domain

In the third step, you decide whether the new domain for your iCloud account should be available exclusively for you (“Only You”) or also for your family members (“You and Your Family”). After you have made your selection, specify your custom email domain that you want to connect to the iCloud and continue the setup process via “Continue”.

Step 4: Update the settings with the domain registrar

Now you need to adjust a few settings in your account at your domain provider. Specifically, these are the settings for MX records, TXT records, and CNAME records. To do this, click “View” in the iCloud menu under “Update your domain registrar’s settings” and transfer the corresponding values to your domain provider’s account.

With some providers, iCloud Mail automatically helps with the setup. In this case, all you need to do is click “Next”. If you log in to your provider afterwards, the adjustment of the mentioned entries will be done for you automatically.

Step 5: Finish the set up

In the last step, press the “Finish set up” button to finish linking the iCloud and your personal domain. If the setup was successful, you will receive a message saying so. Click on “Next” and add the desired email address under your own domain.
