Bulk Email Verifier

Choose Single Email mode to get a detailed breakdown for one address, or Bulk List mode to verify hundreds at once. In both modes the same six checks run on every address.

Format validation runs instantly in the browser: RFC 5322 structure, local part length, dot placement, and TLD rules. Each address is then compared against a database of disposable email domains and scanned for role-based prefixes — admin, noreply, support, and similar shared inboxes.

With MX checking enabled, the tool sends a request to our server, which performs DNS lookups to confirm whether each domain has active mail server records. In MX-only mode, only domain names are sent for verification. If you enable Deep Verify, full email addresses are sent so the server can run SMTP mailbox checks. Domains with no MX records are marked Undeliverable.

Every result gets a deliverability score from 0 to 100. A clean custom-domain address with verified MX scores 92–100. Webmail providers (Gmail, Outlook) score slightly lower due to engagement patterns. Disposable or role-based addresses score 35–75. Addresses with no MX record score under 10.

Single mode shows each of the six checks — Format, MX, Disposable, Role-based, Webmail, and Catch-all — in a card with a score bar. Bulk mode shows compact check indicators per row with filter tabs, search, CSV export, and one-click copy of filtered groups.
