The success rate of recovering deleted emails on a Mac can be affected by several factors, including:
Time since deletion: The sooner you attempt to recover a deleted email, the higher the chances of success. With time, the space occupied by the deleted email may be overwritten by new data, making recovery more difficult or even impossible.
Type of deletion: If an email has been permanently deleted from the Trash folder, it becomes more challenging to recover. However, if the email is still in the Trash folder or has been archived, recovery is much more straightforward .
Email client and service: The success rate can vary depending on the email client (e.g., Apple Mail, Outlook, or Thunderbird) and email service provider (e.g., iCloud, Gmail, or Yahoo) used. Some providers and clients may have additional built-in recovery features that others do not.
Backup availability: If you have a Time Machine backup or iCloud backup of your emails, the chances of successfully recovering deleted emails are significantly higher.
Data recovery software: The effectiveness of data recovery software, like Disk Drill, depends on its compatibility with the email client and service, as well as the software's ability to locate and restore the deleted emails [3].
By considering these factors, you can have a better understanding of the success rate for recovering deleted emails on a Mac.
