Bulk Email Checker
Bulk Email Checker checks whether email addresses appear valid, using bulk uploads or checks through a real-time API. Its bulk workflow accepts CSV and tab-delimited files, removes duplicates, checks syntax, DNS/MX records and mailbox status, and supports CSV and Excel output. The maker describes a verification process with more than 17 factors, including RFC validation and deep SMTP checks. Additional checks can identify disposable or role-based addresses, catch-all servers, possible typos and spam traps, and enrich results with MX server information. The RESTful JSON API can check addresses at signup, checkout or CRM entry, with support for Python, PHP, Node.js and other major stacks. Integrations listed include blacklist synchronization with MailChimp, SendGrid, Mailgun, Postmark and Mailjet, plus Google Sheets, Excel and WordPress. Ten checks are available without signup, and a free plan and trial are listed. Paid options start at $9.95, paid once purchase for 10,000 verifications; monthly unlimited API plans vary by concurrent threads. The service is available on web, Linux, macOS and Windows, as well as through its API.
