A lightweight way to flag mail without moving it anywhere
Starring works the same in spirit across most services -- Gmail's star, Outlook's flag, Apple Mail's flag. One click marks a message as worth revisiting, without filing it into a folder or committing to a category.
Not every service calls it a "star"
Outlook calls the same feature a "flag," and Apple Mail also uses a flag rather than a star, but the underlying behavior is identical: a visible marker that lets you gather important messages into one dedicated view.
Frequently Asked Questions
Does starring a message move it out of my inbox?
No. The message stays right where it already is; starring only adds a marker and a shortcut to find it again through the dedicated starred view.
Is starring available in the mobile app too?
Yes, most mail apps offer the same starring or flagging feature on mobile, and starred messages sync across devices signed into the same account.
