Bulk Email Validation API - Validate and Verify Emails in Bulk
Our Bulk Email Validation API provides a reliable way to validate and verify multiple email addresses in a single request. Built for high-volume processing, the API checks each address for invalid emails, MX record and domain issues, disposable and temporary inboxes, catch-all domains, role-based accounts, spam traps, syntax problems, and other key email quality signals.
Use our bulk email verification API to clean email databases at scale, improve deliverability, reduce bounce rates, remove risky or low-quality addresses before campaigns, block disposable and temporary emails from entering your system, and identify typographical mistakes, catch-all domains, and other problematic addresses across your entire list. This endpoint returns the same validation depth as our Single Email Checker API while processing up to 100 email records in one request.
Features
Bulk MX Record Checks
Verify MX records across large email lists in a single request. Detect domains with invalid or missing mail server configuration and remove addresses that are unlikely to receive email successfully.
Bulk Email Syntax Checking
Validate email syntax for every address in your batch to catch malformed entries, typographical mistakes, and invalid formatting before they waste sending volume.
Disposable Email List Filtering
Find temporary and disposable email addresses at scale and keep risky, low-quality contacts out of your database.
Spam Trap & Role Account Detection at Scale
Screen large lists for spam traps and role-based accounts to improve deliverability and protect sender reputation.
Bulk B2B Contact Screening
Identify free email providers across your list and focus on genuine business contacts for stronger B2B outreach.
Catch-All Domain Analysis at Scale
Detect catch-all domains in bulk to reduce bounce risk and avoid wasting campaign resources on uncertain addresses.
List Enrichment with IP Geolocation
Add optional IP-based location insights to bulk validation results for profiling, monitoring, and fraud review.
Bulk Proxy, VPN & Tor Risk Screening
Detect contacts linked to VPNs, proxies, and Tor exits to uncover suspicious records across large datasets.
Maximum Efficiency with 100 Emails per Request
Our API supports up to 100 emails per request which enables you to process extensive batches of emails simultaneously, significantly streamlining your workflow and ensuring rapid and accurate results.

How-To-Guides
Validate Bulk Email Address List
Provide multiple email addresses in the request body to receive validation results. Each item in the response corresponds to one validation attempt and includes syntax, domain, DNS, and account analysis.
# Response { "emailValidationResponses": [ { "success": true, "email": "someone@gmail.com", "name": "ABC Person", "validEmail": "valid", "validSyntax": true, "domain": { "name": "gmail.com", "disposable": false, "spam": false, "free": true, "validDomain": true, "catchAll": false }, "account": { "role": false, "fullMailBox": false }, "dns": { "mxRecords": [ "gmail-smtp-in.l.google.com.", "alt1.gmail-smtp-in.l.google.com.", "alt2.gmail-smtp-in.l.google.com.", "alt3.gmail-smtp-in.l.google.com.", "alt4.gmail-smtp-in.l.google.com." ] } }, { "success": true, "email": "someone@fastmail.com", "name": "XYZ Person", "validEmail": "valid", "validSyntax": true, "domain": { "name": "fastmail.com", "disposable": false, "spam": false, "free": true, "validDomain": true, "catchAll": false }, "account": { "role": false, "fullMailBox": false }, "dns": { "mxRecords": [ "in1-smtp.messagingengine.com.", "in2-smtp.messagingengine.com." ] } } ] }curl -X 'POST' \ 'https://api.apifreaks.com/v1.0/email-validation/bulk?apiKey=API-KEY' \ -H 'Content-Type: application/json' \ -d '{ "emailData": [ { "email": "someone@gmail.com", "name": "ABC Person" }, { "email": "someone@fastmail.com", "name": "XYZ Person" } ] }'
Validate Bulk Emails with IP Enrichment
Including an IP address in each object enriches the response with detailed security insights and precise location data for that IP.
