A success alert is a message delivering positive news — confirming that a message has been sent, updates are saved, or an image is successfully uploaded. It serves as a reassuring confirmation that all is well, allowing users to proceed with their tasks confidently. The use of green in the alert signifies a positive and successful system message and a check mark further reinforces the confirmation that everything is functioning properly.

Remember that success alerts are designed not to be intrusive. Typically, they either vanish automatically or can be dismissed by a simple swipe.
