EMAIL VALIDATION

Send to real inboxes only.

Validate email addresses before they cost you deliverability. Check MX records, confirm mailbox existence, and filter out disposable addresses — all without sending a single message.

Capabilities

Protect your sender reputation.

MX checks, mailbox existence, disposable and role detection, and typo suggestions — before a single email is sent.

MX record verification

Confirms the domain has valid mail exchange records — the domain can receive email.

Mailbox existence

Checks whether the specific mailbox exists without sending a test email.

Disposable address detection

Flags addresses from throwaway email services (Mailinator, Guerrilla Mail etc.).

Role address detection

Identifies generic addresses (info@, admin@, noreply@) that rarely belong to real users.

Format validation

RFC-compliant syntax check before any network query.

Typo suggestions

Common domain typos (gmail.con, hotmai.com) returned with a did-you-mean suggestion.

Where it shines

Stop bounces before they happen.

Signup form validation

Check email validity at registration. Reduce bounce rates before they affect your sender score.

Forms

List hygiene before campaign

Validate your full email list before a large send to remove invalid addresses.

Campaigns

Lead quality scoring

Flag leads with disposable or role addresses for manual review before entering CRM.
