Why is Mail Using So Much Storage on Mac

Mail downloads, recognized as attachments, are a big feature in the inboxes, either consuming a lot of space in the cloud in case you’re using a cloud-based email client, or on your phone and if you’re using a desktop-based client, on the Mac as well. The attachments are stored in many places and it is probable that there are numerous versions of an attachment stored in different places, using a lot of storage.

It is possible that when you have downloaded and used an attachment, you will not need the original file. Or once you have worked on a folder or document, you have saved more than a single copy on your system, and you can forward a modified attachment to sender. It means that an attachment usually turns into a minimum of 3-4 versions of the same attachment saved in various folders and in the inboxes or the cloud-based email services.

These attachments are considered to be a very big issue in the Mail Storage and you frequently need to delete these files from Mac mail folders to save more space on your Mac system.
