Email Etiquette
Spam Filter Words
Modern spam filtering uses keywords plus reputation, authentication, and machine learning. Use account controls, aliases, and sender authentication to reduce spam and false positives.
Vacation Autoresponder
Set a clear out-of-office message with a vacation autoresponder: schedule it, say when you'll return, give an alternate contact, and avoid sharing sensitive details.
Microsoft Antispam
Microsoft's modern antispam and email security (EOP, Defender for Office 365) use layered detection - reputation, ML, sandboxing, and URL checks - to block malware and phishing. Pair these services with user habits like not opening unknown mail and enabling MFA.
