Email Tools
Check whether an email address is valid and deliverable.
Enter one or more email addresses, one per line or comma-separated.
Craftora checks each address against its actual mail server and returns a clear status.
See which are safe, risky, or invalid, filter the results, and export them to CSV.
Craftora connects to the mail server behind an address and asks whether the mailbox exists, without sending any email. It checks the format, the domain's mail records (MX), and the mailbox itself, then returns a clear status.
Safe means the address is valid and can receive mail. Invalid means the mailbox does not exist or the domain cannot receive email. Risky means it may work but is uncertain, for example a catch-all domain, a role account, or a full mailbox.
No. Verification uses an SMTP conversation with the mail server that stops before any message is sent. The person you are checking receives nothing.
Email verification connects to real mail servers, so it needs limits to stay fast and free and to prevent abuse. A free Craftora account gives you 50 checks per day. Browser-based tools on Craftora need no account.
A catch-all domain accepts mail for any address, so the server says yes even for addresses that do not really exist. Craftora flags these as risky because deliverability cannot be guaranteed.
The single verifier handles up to 50 addresses at a time. For larger lists, use the Bulk Email Verifier, which is built for batches.
