Are certification programs still relevant?

Certification relevance has decreased as **MBP** filters improved and engagement became dominant. Historical whitelisting models (certified sender, bypass filters) evolved toward reputation and engagement weighting that affects everyone regardless of certification.

Current value depends on: your audience (heavy European/German lists benefit from **CSA**), your volume (certification costs need scale to justify), and your current delivery (already strong delivery gains less from certification).

Certification remains relevant for: senders needing external validation for stakeholders, those with specific **MBP** delivery challenges at participating providers, and organizations wanting structured practice improvement. It's less essential than in earlier eras but still valuable for specific situations.
