When you subscribe to iCloud+, you can use up to five custom domains to send and receive email with iCloud.
iCloud Mail Custom Domains
From 20th September 2021, if you have an iCloud+ subscription, you can personalise your email account to take advantage of your personal domain name.
So instead of gardeningsupplies@gmail.com you could have hello@gardeningsupplies.com.
IMPORTANT — Before you start
Before you can configure Custom Domains, you need to register a domain.
We recommend registering a domain with a service like Namecheap.
It’s a much more professional looking email address and guaranteed to boost your reputation.
Plus, it makes it easier for your to separate your personal and work email addresses — but using the same inbox.
What restrictions are there?
After you setup your domain, you can add any existing email addresses you already own.
