Is ESG required to use Opt-Inbox?
Answers from the sources
Sendio
“No. Opt-Inbox is fully supported as an add-on behind any existing email security platform: Microsoft 365 Defender, Proofpoint, Mimecast, Barracuda, Sophos, Trend Micro, and others. The Sendio bundle (ESG + Opt-Inbox) is an alternative deployment path, not a requirement.”
