- INKY Outbound Mail Protection
Best for: Teams wanting manager approval for risky email
INKY earns its spot because it puts an approval step inside the email itself, so a sender or a named manager signs off before sensitive data leaves. That suits a team that wants a human check rather than a silent block, on Microsoft 365, Google Workspace or Exchange. INKY changed owners recently, so ask how the product will be sold and supported from here.

- Trustifi Outbound Shield
Best for: Companies that must encrypt regulated data
Trustifi is here because it turns a detection into encryption, so sensitive mail still goes out but arrives protected, which suits regulated companies working under HIPAA, GDPR or CCPA. Because it runs on several mail platforms, it also covers mixed setups. Check how people outside your company experience the one-click decrypt and the extra verification step before you roll it out.
