macOS screen shots default to the PNG format. You can change that to JPG which will result in a much smaller file size by running this command in the Terminal…
defaults write com.apple.screencapture type jpg;killall SystemUIServer
to revert to PNG…
defaults write com.apple.screencapture type png;killall SystemUIServer
This is per-message - add an image to the mail message, and this pop-up automatically appears in the headers, below the To and subject lines.
reduce file size for screenshots.
