For communities without a shared domain, Pro and the one-time CSV Data Suite provide address allowlists; Pro also includes an API for syncing lists from external systems. The hosted bot includes 25 verification emails per server each month at no charge, with monthly subscriptions and non-expiring credit packs for additional usage.

    BounceLens

    BounceLens

    BounceLens

    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.
