Email apps receive frequent updates that change their interface and features. Recent iOS and Windows updates have brought significant changes to Mail apps across different platforms. Users can update their Mail apps through the Microsoft Store on Windows or automatically through iOS updates on iPhone to access new security features, interface improvements, and enhanced email management tools.

The latest Mail app updates focus on improving email organization and security. New features include advanced email blocking, priority mail sorting, and refined formatting options that help users manage their inbox more efficiently.

Update Mail App: Tips for Better Performance

Apple’s Mail app is a reliable email client for macOS, but over time it can slow down due to large mailboxes, outdated software, or background processes. Keeping it updated and optimized can dramatically improve performance.


1. Keep macOS and Mail App Updated

  • Why it matters: Updates often include bug fixes, performance enhancements, and improved compatibility with mail servers.
  • How to update:
    1. Click Apple Menu → System Settings → General → Software Update.
    2. Install any available macOS updates — the Mail app updates automatically with macOS.
  • Tip: Enable Automatic Updates to ensure you always run the latest version.

2. Rebuild Mailboxes

Over time, Mail’s database can become bloated or corrupted. Rebuilding helps clean and reindex messages.
Steps:

  1. Open Mail → select a mailbox (e.g., Inbox).
  2. Go to Mailbox → Rebuild.
  3. Wait for Mail to re-download and reindex messages.
    (Note: This can take time depending on mailbox size.)

3. Remove Old Emails and Attachments

Large attachments and old messages can slow Mail’s performance.
To clean up:

  • Sort by size and delete large or unnecessary emails.
  • Use Mailbox → Erase Junk Mail and Mailbox → Erase Deleted Items.
  • Store old emails in an archive or external backup.

4. Optimize Mail’s Storage

Mail caches data locally to speed up access, but excessive cached data can slow things down.
To clear Mail cache:

  1. Quit Mail.
  2. Open Finder → Go to Folder →~/Library/Mail/V10 (or the latest version folder)
  3. Delete cache folders (not the entire Mail folder).
  4. Reopen Mail — it will rebuild fresh cache data.

5. Disable Unnecessary Accounts or Mailboxes

If you have multiple accounts linked, each one syncs and indexes mail, which can slow performance.
To optimize:

  • Go to Mail → Settings → Accounts.
  • Disable accounts you rarely use or remove them entirely.

6. Reduce Background Activity

  • Turn off “Automatically Download Attachments” under Mail → Settings → Accounts → Advanced.
  • Disable “Load Remote Content in Messages” to reduce bandwidth use.

7. Reindex Spotlight for Mail

If search in Mail is slow or inaccurate:

  1. Open System Settings → Siri & Spotlight → Spotlight Privacy.
  2. Add and then remove the Mail folder to force a reindex.

8. Check for Third-Party Conflicts

Some background agents (like antivirus or sync tools) can interfere with Mail.

  • Disable or uninstall unnecessary login items under System Settings → General → Login Items.

9. Test in Safe Mode

Booting into Safe Mode can help identify if third-party extensions are causing issues.

  • Restart your Mac and hold Shift during startup.
  • Open Mail — if it runs faster, a background app may be the culprit.

10. Consider a Clean Mail Setup

If problems persist:

  1. Back up your Mail data.
  2. Remove the Mail folder from ~/Library/Mail/.
  3. Re-add your email accounts to start fresh.

✅ Final Thoughts

By keeping your Mail app and macOS updated, clearing out old data, and managing background processes, you can restore speed and reliability. Regular maintenance — like rebuilding mailboxes and cleaning caches — ensures smooth performance even with large inboxes.
