How to Speed Up Mac Mail: Top Methods to Fix Slow Apple Mail
Apple/Mac Mail is a powerful and reliable email client, but like any software that constantly handles new incoming data, it can sometimes slow down. Whether you’re experiencing a sluggish interface, long loading times, or other performance issues, there are several effective steps you can take to speed up Apple Mail and improve your overall experience. In this post, we’ll explore practical methods to help you get your Mac Mail running smoothly again.
Why Is Apple Mail Slow?
Several common factors can cause Mac Mail to run slowly:
- Large Mailboxes: The bigger your mailbox, the longer it takes to load and search through emails. Large mailboxes are often the main culprit behind sluggish Apple Mail performance.
- Complex Filters: Using overly complex or numerous filters can significantly slow down email sorting and categorization.
- Outdated Software: Running an old version of Apple Mail or macOS may lack the latest performance optimizations.
- Network Limitations: Slow internet connections or server outages can disrupt email downloads and syncing, leading to delays.
While the causes can vary, the solutions to speed up Apple Mail often overlap. Let’s explore some effective ways to boost your Apple Mail’s performance.
Steps to Speed Up Mac Mail
To help you quickly fix a slow Apple Mail, we’ve divided the troubleshooting into four key sections. Depending on your situation, you can jump to the relevant method and get your email client running smoothly again.
1. Optimize Your Mac’s Overall Performance
Before diving into Apple Mail-specific fixes, it’s important to ensure your macOS is up to date and running optimally, as system performance directly impacts app speed.
Update macOS:
- Click the Apple Menu in the top-left corner of your screen.
- Select System Settings > General.
- Click Software Update.
- If any updates are available, you’ll see a notification.
- Click Update Now to install all available updates.
Keeping your macOS updated ensures you have the latest performance improvements and bug fixes, which can help speed up Apple Mail as well.
# Check for Malware
Malware or viruses can significantly impact your Mac’s performance, including slowing down Apple Mail. macOS comes with built-in security features like Gatekeeper, xProtect, and Firewall that help detect and prevent malicious software. You might see warnings such as “can’t be opened because Apple cannot check it for malicious software” when these features block suspicious apps.
To keep your Mac safe and ensure smooth Apple Mail performance:
- Regularly scan your system for malware using trusted antivirus tools.
- Pay attention to any security warnings and avoid opening unverified files or apps.
# Free Up Disk Space
Low disk space can also cause your Mac and Apple Mail to slow down. To free up space:
- Delete unnecessary files and empty your Trash.
- Remove large files from the Downloads folder or other locations you no longer need.
- Uninstall apps you don’t use anymore.
For more thorough cleanup, tools like CubexSoft Date Wipe can help permanently delete unwanted emails and files, freeing up storage and improving overall system speed.
2. Clean Up Mac Mail Inbox
A cluttered inbox with too many unwanted emails can slow down Apple Mail’s performance. Here are some effective ways to tidy up and boost speed:
Locally Save Old Emails:
If you have important emails you want to keep but don’t need immediate access to, consider backing them up externally. Export Mac Mail emails to an external hard drive, then remove them from your Mac Mail inbox to reduce clutter.
Delete Unnecessary Emails:
- Open the Apple Mail application.
- Select the emails you want to delete (use Shift or Command key for multiple selections).
- Right-click and choose Delete.
- Confirm by clicking OK.
Deleting excess emails, especially large ones, can free up resources and significantly improve Mail’s speed.
Unsubscribe from Unwanted Newsletters:
Many newsletters automatically pile up in your inbox, causing clutter. Scroll to the bottom of such emails and use the Unsubscribe link to stop receiving them. This helps keep your inbox cleaner and your Mail app running faster.
Troubleshooting Specific Issues to Speed Up Mac Mail
If you’ve already optimized your system and cleaned up your inbox, but Apple Mail still feels sluggish, try these targeted troubleshooting steps:
Rebuild the Mailbox
One of the most effective ways to fix performance-related issues in Apple Mail is to rebuild the mailbox. This process refreshes your local mailbox data without deleting any emails.
Steps to Rebuild the Mailbox:
- Open the Apple Mail application.
- In the top menu, click on Mailbox.
- Select Rebuild from the dropdown list.
- Apple Mail will then begin recreating the selected mailbox.
Note: Rebuilding can take a little time depending on the size of your mailbox. During this process, Mail will re-download messages from the server.
Check Your Internet Connection
A slow or unstable internet connection can directly impact Apple Mail’s ability to send, receive, or sync messages.
Disable Mail Drop
Apple Mail’s Mail Drop feature is helpful for sending large attachments via iCloud, but it can sometimes interfere with performance. Disabling it might improve Mail’s responsiveness.
Steps to Disable Mail Drop:
- Open the Mail app.
- Click Mail in the top menu bar and choose Preferences.
- Go to the Accounts tab.
- Select the email account in question and click on Account Information.
- Uncheck the option “Send large attachments with Mail Drop.”
This change ensures that large attachments are sent directly through your mail server rather than being uploaded to iCloud, which can reduce delays.
Reset Mac Mail (Last Resort)
If none of the above methods resolve the issue, you can choose to reset Apple Mail. This action will completely remove all Mail data from your system, including accounts, settings, and downloaded emails.
Warning: This is a permanent action. It’s highly recommended to back up your important emails and settings before proceeding.
Pro Tip: Before resetting, make sure to back up your data. Not sure where your emails are stored? Check out our detailed guide, where are emails stored on Mac Mail, to locate and back up your Apple Mail files safely.
Use a Professional Tool to Speed Up Apple Mail
If all manual fixes fail to restore Apple Mail’s performance, consider using a professional utility like the Apple Mail Converter tool.
Mac Mail Converter is a professional utility designed to convert Apple Mail mailbox data (in MBOX or EMLX format) into multiple file formats and email platforms. This tool is ideal for users who want to migrate, back up, or archive their Apple Mail data with complete accuracy and security.

Conclusion
A smooth and responsive Apple Mail experience comes down to a mix of regular maintenance, smart settings adjustments, and effective troubleshooting. Whether you’re dealing with large mailboxes, outdated software, or general sluggishness, the methods outlined in this guide can help you significantly improve performance. Even without deep technical knowledge, any user can follow these practical steps to speed up Mac Mail, keeping it fast, clean, and efficient for daily use.
