Apple has quietly expanded its custom email address limits for iCloud+ users. Previously capped at just three per custom domain, users can now create up to ten personalized addresses per domain. Users can still register up to five custom domains per account, but each person with access to a domain can now establish ten unique email addresses under it, up from the old cap of three.
What this means for individuals and small businesses
This change isn’t just for power users—it’s especially useful for families and small businesses that rely on custom domains. Under the old limit, businesses or households sharing a domain would quickly run out of usable identities. With ten addresses per user, there’s far more flexibility—allowing each person to have distinct roles, projects, or aliases under the same domain without interfering with others.
How the update came to light
The update surfaced on September 30 when a revision to Apple’s support documents was spotted online. It revealed that the shift applied not just per account, but per individual user who has domain-sharing privileges. So if you share a domain with others, they too benefit individually from the higher limit.
This update replaces the previous policy where each custom domain allowed only three email aliases per user. The maximum five custom domains per iCloud+ account remains unchanged—but the alias limit per domain has more than tripled.
Why Apple made the change
The three-address limit was often insufficient, particularly from a business standpoint. Fact is, many small teams or families need separate addresses for work, school, finances, or administrative purposes. Increasing the allowance to ten responses more closely to real-world usage—and reduces friction when people share domains across their workflows.
This update demonstrates Apple’s ongoing effort to improve usability and responsiveness in its iCloud+ offerings. By raising these limits silently, Apple enabled an enhanced user experience without a major announcement.
Looking ahead, the bigger question is how this change might shift expectations for cloud email services. As providers push more into custom domain options, limit enhancements like this could become table stakes. For users, it’s worth checking their custom domain settings to see if the ten-address limit is already applied—because once it’s available, it makes juggling identities and roles much easier than before.
