Check Your Inbox for Replies

The most straightforward way to know someone replied:

  1. Open Gmail on your computer or mobile device.
  2. Look for the original email thread. Gmail automatically groups replies in a conversation view.
    • If conversation view is on, replies appear nested under the original email.
  3. Look for bolded threads in your inbox — a bolded subject usually means unread messages, which may include replies.

Tip: If conversation view is off, each reply appears as a separate email in your inbox.


Use Email Notifications

Gmail can notify you immediately when a reply arrives:

On Desktop:

  1. Click the gear iconSee all settings.
  2. Go to GeneralDesktop Notifications.
  3. Choose New mail notifications on.
  4. Click Save Changes at the bottom.

Result: You’ll see a popup notification when someone replies.

On Mobile:

  1. Open Gmail appMenuSettings.
  2. Tap your account → NotificationsAll.
  3. Make sure Label notifications are enabled for important labels like Inbox.

Result: You’ll get push notifications when a reply arrives.


Track Replies Using “Snooze” or “Star”

You can mark emails to follow up if you haven’t received a reply:

  • Snooze: Temporarily remove an email from your inbox and get a reminder later.
  • Star: Highlight important messages to easily check if a reply has arrived.

How to Snooze a Message:

  1. Hover over the email → Click the clock icon.
  2. Set a date/time to remind you if no reply has come.

How to Star a Message:

  1. Click the star icon next to the email.
  2. Use the Starred label to monitor important threads.

Use Gmail’s “Follow Up” Suggestions

Gmail automatically suggests follow-ups for emails that haven’t been replied to:

  • Open Gmail → Conversation with sent email.
  • Look for the “Follow up” prompt under your sent email.
  • Gmail shows if it detects no reply has been received.

  1. Compose a new email → Click the three dots (More options)Request read receipt.
  2. Send the email.
  3. You’ll get a notification when the recipient opens your email.

Note: This only works with Workspace accounts and recipients may decline to send a read receipt.
