    Frequently asked questions

    How do I check if an email address at icloud.com is valid?

    Enter the address in the verifier above. VeriMailX checks the syntax, resolves the MX records for icloud.com, opens an SMTP conversation with the receiving mail server and reports whether the mailbox accepts mail — without sending an email.

    Is icloud.com a catch-all domain?

    Catch-all configuration is set by whoever administers icloud.com, and it can change at any time. A live verification tells you whether the server accepted the specific address or accepts everything, which is why catch-all status is reported per check rather than stored as a fixed value.

    Can I verify a bulk list of icloud.com addresses?

    Yes. Upload a CSV of up to 50,000 rows per file, or call the API for real-time checks at signup. Results include deliverability status, disposable and role-based flags, and a confidence score for each address.
