Bulk Email Checker
What Bulk Email Checker is
Bulk Email Checker verifies whether email addresses appear real or fake, through bulk list uploads and real-time checks at signup, checkout, or CRM entry. The web application accepts CSV and tab-delimited uploads, removes duplicates, checks syntax, DNS/MX records, and mailbox status, and supports CSV and Excel files. Its stated 17+ factor process includes RFC validation and deep SMTP verification. Checks can flag disposable and role addresses, catch-all servers, typos, and spam traps, and add MX server details. The RESTful JSON API supports Python, PHP, Node.js, and other major stacks. Listed integrations include blacklist synchronization with MailChimp, SendGrid, Mailgun, Postmark, and Mailjet, plus Google Sheets, Excel, and WordPress. The company describes TLS 1.3 in transit, AES-256 encryption, isolated encrypted data containers, and a zero-knowledge design that prevents staff access to email lists. It lists SOC 2 Type II, ISO 27001, HIPAA, GDPR, and CCPA under enterprise-grade compliance. Ten checks are available without signing up. One-time verification packs start at 9.95 USD, and monthly unlimited API plans vary by concurrent threads. Bulk Email Checker was founded in 2012 and is available on web, Linux, macOS, Windows, and API.
