How our email checker works
We perform several checks and return clear outcomes for every verification.
Email verification checks
We perform several checks when verifying emails.
-
Syntax check
Ensures the email format is correct to prevent hard bounces.
-
Domain check
Confirms the domain exists and can receive mail.
-
Disposable screening
Identifies temporary or disposable addresses that expire.
-
Role-based detection
Flags shared inboxes (e.g. support@, info@) that may not belong to an individual.
-
Mailbox check
Confirms the mailbox is valid and deliverable. No email is sent.
Email verification outcomes
These are the possible results of an email verification.
-
Valid
Confirms the address is deliverable and safe to use for outreach.
-
Catch-all
Domain accepts all messages; the specific recipient may not exist.
-
Invalid
Undeliverable: bad syntax, non-existent domain, or mailbox not found.
-
Unknown
Uncertain status, e.g. server restrictions or timeouts.
-
Pending
Temporary status while we process large lists.
