Use enhanced pre-delivery message scanning
When Gmail identifies that an email may be phishing, it might show you a warning or move the email to Spam. Enhanced pre-delivery message scanning improves how to identify suspicious content.
When Gmail detects suspicious content, it introduces a short delivery delay to perform additional checks. Gmail does this through a setting turned on for all domains and controlled in the Admin Console.
