Anti-spam approach	AI-powered filtering Google says stops more than 99.9% of spam, phishing and malware, plus sender-authentication requirements for bulk senders that Google says cut unauthenticated messages 75%. Google's privacy policy lists 'email you write and receive' among the content it collects, and with smart features on Google uses Gmail data to provide those features; Google states Gmail content is not used for ads personalization.	Described by Posteo only as a 'highly efficient spam and virus filter' — no further technical methodology is publicly documented.
