About

BounceLens is a browser-based email list checker for marketers, newsletter publishers, online shops, sales teams, and developers. Users can paste addresses or check a CSV list for malformed syntax, domains that do not exist or have no mail service, likely domain typos, disposable addresses, duplicate entries—including Gmail dot and plus-tag variants—and role accounts such as info@ and sales@. The checker uses public DNS information to assess domain mail configuration; it does not contact recipient mail servers or confirm whether an individual mailbox exists, so acceptable results are labeled unconfirmed rather than verified. It can help teams identify addresses that may be invalid or risky before sending or storing email lists. The product is also offered through extensions and add-ons, a self-hosted HTTP API, an MCP server, and language libraries for incorporating the same checks into other workflows.

About

Bulk Email Checker has verified more than 12 billion addresses since 2012 for over 400,000 customers. Real-time SMTP verification delivers 99.7% accuracy by handshaking directly with mail servers rather than querying cached databases. Upload a CSV or TXT file to clean an existing list, or call the REST API to validate addresses at signup and checkout. Every result includes disposable detection, role account flags, catch-all handling, spam trap identification, domain typo correction, and MX server intelligence returning IP, hostname, location, ISP, and ASN. Pricing is pay-as-you-go from $2.95 per 1,000 verifications down to $0.000132 per address at 25 million. No monthly fees, no contracts, and credits never expire. Duplicates and unknown results consume nothing. High-volume users can switch to the Unlimited API for flat thread-based pricing from $250 per month with no per-email cost.
