Bulk Email Validator - SMTP Check, Catch-All & Risk Score

Validate large lists of email addresses with syntax checking, MX record verification, disposable email detection, role-based email flagging, and risk scoring. This actor processes emails in bulk and returns detailed validation results for each address.

Why Use This Actor?

Sending emails to invalid or risky addresses damages your sender reputation and wastes resources. This actor validates every email in your list before you send, helping you maintain high deliverability rates and clean contact databases without relying on expensive third-party validation services.

Key Features

• Syntax Validation: Checks email format against RFC standards
• MX Record Verification: Confirms the email domain has valid mail exchange records via DNS lookup
• Disposable Detection: Flags temporary/throwaway email providers (Mailinator, Guerrillamail, YopMail, etc.)
• Role-Based Detection: Identifies generic addresses (info@, support@, admin@) vs personal emails
• Free Provider Detection: Flags free email providers (Gmail, Yahoo, Hotmail, etc.)
• Risk Scoring: Assigns a 0-100 risk score based on combined validation signals

Input Parameters

Parameter	Type	Description
emails	array	List of email addresses to validate
checkSmtp	boolean	Verify MX records for domains (default: true)
checkDisposable	boolean	Flag disposable email providers (default: true)

Output Format

Each result includes the email, syntax validity, MX record status, disposable flag, role-based flag, free provider flag, MX records list, risk score, and overall validity. Data is stored in the Apify dataset and exportable as JSON, CSV, or Excel.

Example Use Cases

• Email List Cleaning: Remove invalid and risky addresses before sending campaigns
• Lead Qualification: Score incoming leads based on email quality
• CRM Hygiene: Periodically validate contacts in your database
• Signup Verification: Check email quality during user registration flows

Integration

Use the Apify API to validate emails programmatically. Integrate with Zapier, Make, or custom webhooks. Schedule regular validation runs to keep your contact lists clean over time.

Cost Estimation

Each email validated costs approximately $0.00075 using pay-per-event pricing. Validating 1,000 emails costs around $0.75, making bulk validation extremely affordable compared to commercial email verification services.
