Validate thousands of email addresses in bulk with DNS MX record verification, syntax checking, disposable email detection, and free provider identification. Clean your email lists before sending campaigns to improve deliverability and protect your sender reputation.

What Checks Are Performed?

Every email address goes through four validation layers:

• Syntax validation: RFC-compliant regex check catches typos and malformed addresses
• DNS MX lookup: Verifies the domain has active mail servers that can receive email
• Disposable detection: Flags temporary/throwaway emails (Mailinator, Guerrilla Mail, etc.)
• Free provider check: Identifies Gmail, Yahoo, Outlook, and other free providers vs. business domains

Use Cases

• Email list cleaning: Remove invalid and risky addresses before campaigns to boost deliverability
• Lead qualification: Separate business emails from free providers for B2B outreach
• CRM hygiene: Regularly validate your contact database to maintain data quality
• Signup verification: Validate user emails during onboarding to prevent fake registrations
• Data enrichment: Add validation status, domain type, and MX records to existing contact lists
• Bounce prevention: Eliminate hard bounces before they damage your sender score

Quick Start

Python SDK

from apify_client import ApifyClient
client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("nexgendata/email-validator").call(
 run_input={
"emails":[
"test@gmail.com",
"fake@nonexistentdomain12345.com",
"info@apple.com"
]
}
)
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
print(f"{item['email']}: {item['status']} (MX: {item['hasMx']})")

cURL

curl"https://api.apify.com/v2/acts/nexgendata~email-validator/runs?token=YOUR_API_TOKEN"\
-X POST \
-H"Content-Type: application/json"\
-d'{"emails": ["test@gmail.com", "fake@invalid.xyz"]}'

Example Output

{
"email":"info@apple.com",
"status":"valid",
"syntaxValid":true,
"hasMx":true,
"mxRecords":["mx1.apple.com","mx2.apple.com"],
"isDisposable":false,
"isFreeProvider":false,
"domain":"apple.com"
}

Input Parameters

Pricing

Pay only for what you validate — no monthly fees:

• $0.005 per email validated
• Example: 1,000 emails = $5.00
• Compare: ZeroBounce charges $0.008/email, NeverBounce $0.008/email

Why Use This Over ZeroBounce or NeverBounce?

FAQ

How accurate is the validation? Syntax + DNS MX checking catches 95%+ of invalid addresses. This validates that the domain can receive email, which is the most reliable server-side check available without actually sending a test email.

Can I validate thousands of emails at once? Yes — pass your entire list in one run. The actor processes emails in parallel for fast throughput.

Does this check if the specific mailbox exists? It verifies the domain has working mail servers (MX records). Full mailbox verification (SMTP check) is not included as many mail servers block these probes.

Can I schedule regular list cleaning? Yes — use Apify Schedules to validate your lists weekly or monthly automatically.

What format should my email list be in? Pass emails as a JSON array. For CSV files, use Apify's dataset import to convert first.

Integrations

Connect to your CRM and marketing tools with Zapier, Make.com, or the Apify API. Export results as JSON, CSV, or Excel for direct import into Mailchimp, HubSpot, Salesforce, or any platform.
