What Bulk Email Checker is
Bulk Email Checker verifies email addresses in uploaded lists or through a real-time API. Its web application accepts CSV and tab-delimited uploads, removes duplicates, checks syntax, DNS/MX records, and mailbox status, and supports CSV and Excel files. The service describes its verification as using more than 17 factors, including RFC validation and deep SMTP checks. Other checks can identify disposable and role addresses, catch-all servers, possible typos, spam traps, and MX server details. A RESTful JSON API can check addresses at signup, checkout, or CRM entry, with support for 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, and a zero-knowledge design. Ten checks are available without signing up.
