Clear Mail attachments

Email attachments in Mail accumulate on your Mac even after you've read them — each download takes up space that adds up over time. CleanMyMac finds and removes recoverable attachments from Mail, without touching files you've already modified.

1. In CleanMyMac, click Cleanup in the sidebar, then click Scan.

   

   After scanning, CleanMyMac shows you the scan summary.

2. In the scan summary, click Review All Junk to see all junk categories.

   Alternatively, in the Mail Attachments tile, click Review to go directly to the category, or click Clean to delete all attachments without reviewing.

   

   Tip

   To scan again, click Start Over on the upper left, confirm, then click Scan.

   CleanMyMac opens the Cleanup Manager.

3. In the Mail Attachments category, browse and review the attachments.

   

   You can search for specific attachments and sort them by size or name in ascending or descending order.

   Right-click an attachment to:

   • Select it for removal
   • Reveal it in Finder
   • Get file info
   • Add it to the ignore list
   • Preview it in Quick Look

   

4. Select the attachments you want to remove, then click Clean Up.

   • To select all attachments at once, right-click the Mail group or click Select above the mailboxes, then choose Select All.

   • To select attachments in bulk automatically, right-click the Mail group or click Select above the mailboxes, then choose to apply Smart Selection — CleanMyMac automatically selects all items except those you've already modified.

     

   • To select all attachments in a mailbox, right-click a mailbox, then choose "Select [mailbox]".

   • To select an individual attachment, expand a mailbox, right-click an attachment, then choose "Select [attachment]".

     

   Note

   CleanMyMac only removes items in the currently viewed category. For example, if you select items in the AI Clutter category, then switch to the System Junk category and click Clean Up there, CleanMyMac only deletes files in the System Junk category.

5. Check the results.

   • To explore the details, click View Log.

   • To continue reviewing other categories, click Review Remaining Items to return to the Cleanup Manager.

   • To return to the scan summary, click Done.
