Bulk Email Validator

Clean your email list before it costs you. Validate up to 500 addresses per run — format check, MX record lookup, and disposable domain detection — for $0.01 each.

Bad emails bounce. Bounces hurt deliverability. Disposable signups waste your sales team's time. Fix the list before it becomes a problem.

Features

• Format Validation: Checks email syntax using RFC-compliant validation
• MX Record Lookup: Verifies that the domain has valid mail exchange (MX) records via public DNS
• Disposable Domain Detection: Identifies temporary/throwaway email services (mailinator, tempmail, guerrillamail, etc.)
• Batch Processing: Handle up to 500 emails per run
• Caching: Automatically caches MX lookup results to avoid redundant DNS queries
• Pay-Per-Email Pricing: Only pay $0.01 per email validated

Field	Type	Required	Description
emails	array	✓	List of email addresses to validate (max 500)
checkMx	boolean	-	Enable MX record verification (default: true)

Example Input:
