Why does my iCloud address show as risky?

Because Apple's mail servers don't give an answer that can be treated as confirmation of the mailbox. Rather than guess valid, the checker reports risky once syntax, domain, disposable and role checks pass. Risky means unconfirmed, not bad.

Can the checker say an iCloud address is invalid?

Yes, for things it can check: broken syntax, a typo domain with no mail server, or a disposable domain. It won't call a well-formed icloud.com address invalid just because Apple didn't confirm it.

Is a me.com address the same as icloud.com?

Both are iCloud Mail and use the same Apple mail servers. me.com and mac.com are older Apple address domains; they are checked the same way as icloud.com.

What is a Hide My Email address?

An iCloud+ feature that creates unique, random addresses forwarding to the user's real inbox. They are legitimate and reach a real person, but each one is a separate string you can't link to the main address.

Is this iCloud checker free?

Yes, five checks a minute with no account. For a whole list, sign in with Google for 100 free email checks, no card.

iCloud email checker: what can and can't be confirmed

This iCloud email checker tests an icloud.com, me.com or mac.com address for broken syntax, typo domains, a missing mail server, and disposable or role use, without sending anything. Apple's mail servers don't give a mailbox answer that can be treated as confirmation, so an address that passes comes back risky, not valid. Invalid still means invalid.

iCloud address

Tuned for icloud.com, me.com, mac.com. Five checks a minute, no account needed. Nothing is sent to the address — we ask its mail server whether the mailbox exists, then disconnect.

SimpleAPI

Sample result

name@icloud.com passes every check that can run, but Apple won't confirm it.

Email: name@icloud.com
Reason: Provider hides mailbox status
Mailbox check: Not run: provider won't confirm

What this means for you

Risky means unconfirmed, not bad; a confirmed signup is a reasonable send.

How do I check an iCloud email address?

Type or paste one address, such as name@icloud.com, name@me.com or name@mac.com.
Press Check. Syntax, domain, mail server, disposable and role checks run.
Read the verdict. Invalid means the address can't receive mail. Risky with "Provider hides mailbox status" means it passed everything that can be checked, but Apple didn't confirm the mailbox.
Decide risky iCloud addresses by where they came from: a confirmed signup is a reasonable send, an old list needs care.

Example

You enter: One address: name@icloud.com.
You get: Risky, with the reason "Provider hides mailbox status": syntax, domain, disposable and role checks passed, but Apple's mail servers don't confirm mailboxes, so no mailbox probe is run. A broken address or a disposable domain comes back invalid.
Limits: Five checks a minute per IP address, one address at a time, no account needed.

Can you check if an iCloud email address exists?

Not with certainty, and this checker doesn't pretend to. iCloud addresses are handled by Apple's mail hosts mx01.mail.icloud.com and mx02.mail.icloud.com (DNS, 22 October 2026), and Apple doesn't publish how they answer a mailbox check. They don't give an answer that can be treated as confirmation, so the checker doesn't open a mailbox probe for iCloud domains. Once syntax, domain, disposable and role checks pass, it returns risky with the reason "Provider hides mailbox status".

That still catches the common problems: a mistyped address, a typo domain with no mail server, a throwaway domain. A tool that calls iCloud addresses valid without explanation is reporting a guess; see how to tell if your email verifier is lying.

Are icloud.com, me.com and mac.com the same?

They are all iCloud Mail. me.com and mac.com are older Apple address domains, and on 22 October 2026 all three published the same two MX hosts at mail.icloud.com. So they are checked the same way and get the same result.

iCloud+ subscribers can also create Hide My Email addresses: Apple describes them as "unique, random email addresses" that forward to the user's real inbox (Apple Support). They look like random strings at icloud.com, they are real ways to reach a person, and they can't be traced back to the main address. See plus addressing and trial abuse for what that means for signups.

Should I send to an iCloud address that comes back risky?

Let the source decide. An iCloud address from your own form, confirmed by double opt-in, is a reasonable send. An address from an old or bought list is not, because nothing in a verifier's answer can vouch for it. When you do send, Apple's postmaster page asks senders to use SPF and DKIM and publish a DMARC policy.

For a whole file, the email list cleaner removes duplicates, bad syntax and dead domains in your browser, and the general email checker runs a full mailbox check on any domain that answers.

Who uses this tool, and for what?

Support teams: Catch a mistyped or throwaway address on a signup that looks like iCloud before you reply.
List owners: See why iCloud addresses sit in the risky bucket, and plan a cautious first send for old ones.
SaaS teams: Recognize Hide My Email relays as real, forwarding addresses rather than junk when you review signups.

What can’t this tool tell you?

It does not confirm that an icloud.com, me.com or mac.com mailbox exists. Those come back risky once the other checks pass.
It can't tell a Hide My Email relay from a main iCloud address, or link the two.
Apple doesn't publish how its servers answer mailbox checks, so this handling is a judgment, stated here.
One address at a time, five a minute.
