Based on the type of emails you open, Gmail can tell what’s important to you and what isn’t by moving your Important email to the top of the list.
→ Select Settings > Inbox.
→ Select the Use my Past Actions button.
This will allow Gmail to analyze your past behavior to figure out what type of mails are important to you.
→ Choose the Show Markers and the Override filters buttons.
→ Set the inbox type to Important first.
