What our shortlists say about the one we picked.
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.
