Bouncer (`usebouncer.com`) is well-regarded in Europe for GDPR compliance and toxicity scoring (`0–5` scale), exposing `/v1.1/email/verify` and batch endpoints. However, Bouncer charges $50 for 10,000 credits and $200 for 50,000 credits, and does not include a bundled suite of free DNS authentication generators (SPF, DKIM, DMARC, BIMI, PTR) or native multi-sheet Excel tab preservation.

In addition, KaijuVerifier includes specialized MX gateway heuristics for legacy Yahoo/Ymail/Rocketmail (`mta5.am0.yahoodns.net`), Microsoft 365 Protection, and Google Workspace catch-all tenants.
