Security software company GreatHorn analyzes 500,000 spear phishing attempts. Software seeks out phishing emails and can autonomously block them, but even its customers dont switch on all the features.

The software can also flag suspicious emails but leave them in the inbox, or move them to a specified folder for examination. Just 7% of emails for which DMARC was configured passed the test.”]
