Bulk Email Checker review
A low-cost choice for bulk verification, with paid-only access and costly unlimited API tiers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Bulk Email Checker is a web-based email verification service for marketers, sales teams, CRM operators, developers, and SaaS applications. It checks individual addresses and bulk CSV or TXT lists using syntax validation, DNS/MX checks, disposable-address detection, role-account filtering, catch-all detection, and real-time SMTP verification. Its REST API supports JSON and XML responses for signup forms, checkout pages, CRMs, and other applications.
Pricing is split between one-time credits and monthly unlimited API plans. Pay As You Go costs $2.95 per 1,000 verifications, includes a one-time credit purchase, and lets credits remain available without expiring. Those credits can support bulk uploads and API use. Unlimited API - 1 Thread costs $250 per month for unlimited verifications, one concurrent connection, and zero overage fees. Unlimited API - 5 Threads costs $1,200 per month, while Unlimited API - 10 Threads costs $2,300 per month. The higher tiers add five or ten concurrent connections. The service also offers 10 free checks, but does not provide an unlimited free plan.
For list-cleaning workflows, the feature set extends beyond basic syntax checks. Duplicate removal, MX server enrichment, and DNS/MX validation help prepare larger lists, while Google Sheets and Microsoft Excel integrations support spreadsheet-based processes. WordPress, Zapier, and n8n add connection points for forms and automation workflows. Choose Bulk Email Checker if low-cost bulk verification, non-expiring pay-as-you-go credits, or API access are the main priorities. Buyers needing unlimited verification at high concurrency should weigh the monthly API pricing carefully, while teams seeking a free ongoing plan should choose a service with that pricing model.
