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
UserCheck is a real-time email validation API that detects and blocks disposable, temporary, and suspicious email addresses and domains so tools can focus on genuine users and reduce fake sign-ups and abuse. It verifies whether an email or domain is valid, active, and trustworthy, checks domain reputation, identifies public email providers, relays, role accounts, and offers smart suggestions for common typos, syntax validation, and bulk processing of large lists. UserCheck continuously updates its disposable email database and enhanced validation rules, and it integrates seamlessly via a simple REST API with predictable JSON responses for efficient, low-latency verification workflows. It scales to handle high volumes of requests without performance degradation and offers organizational features like environment separation for development, staging, and production workflows. Additional capabilities include custom blocklists, webhooks, and integrations with tools.
