Free email verifier
Check if an email address is valid.
Run a free Basic Check for email format, domain, mail-server, typo, disposable, role-inbox, and risk signals. Add a provider-backed Verified Check when mailbox-level confidence matters.
Live email preflight
Check an address right here.
Screen syntax, domain, mail-server, typo, disposable, and role-inbox risk before an address enters your sequence.
Free Basic Check
Reviews syntax, domain, MX, typos, disposable, role-based, and provider signals. It does not confirm the individual mailbox.
Verified Check
Free accounts include provider-backed mailbox checks. Pro and Growth plans renew larger verification limits monthly.
Bulk Email Validation
Upload a CSV, remove duplicates, compare risk signals, and export a cleaner outbound file.
How it works
What an email verification result tells you
1. Address checks
Format and obvious errors
EmailCheq checks syntax and flags common typo, disposable-domain, and shared-inbox risk signals.
2. Domain checks
Domain and mail server
The Basic Check looks for an active domain and MX records that indicate the domain is configured to receive email.
3. Deeper verification
Mailbox-level signal
When you need more confidence, a Verified Check adds a provider-backed mailbox signal where the receiving environment allows it.
Email verification reduces uncertainty; it does not guarantee delivery or inbox placement. Receiving servers, catch-all domains, filtering, reputation, and later mailbox changes can all affect the final outcome.

Common questions about checking email addresses
What does the free email verifier check?
EmailCheq's Basic Check screens email syntax, domain availability, MX mail-server records, likely typos, disposable domains, role-based inboxes, and other risk signals. A Basic Check does not confirm that the individual mailbox exists.
Can EmailCheq confirm that a mailbox exists?
A provider-backed Verified Check adds a mailbox-level signal when available. No email verification result can guarantee delivery or inbox placement because receiving servers can limit or obscure mailbox responses.
What is the difference between email validation and email verification?
Validation usually refers to checking the address format, domain, mail-server setup, and known risk signals. Verification adds a deeper mailbox-level signal when the receiving environment allows it.
Can I verify a CSV list of email addresses?
Yes. EmailCheq's bulk email validator accepts CSV prospect lists, removes duplicate addresses, runs Basic Checks, and lets you export a cleaner outbound file.
