How to Delete an Email Signature Directly from the Signatures Folder (Advanced)
Step 1
Close Apple Mail. Open Finder, click on the Go menu at the top while holding the Option / Alt button on your keyboard.
You will see an option appear called “Library”, click on it.
Step 2
If you’re using iCloud, navigate to this path: /Library/Mobile Documents/com~apple~mail/Data/MailData/Signatures
If you’re not using iCloud, navigate to this path: /Library/Mail/V3/MailData/Signatures
All your email signatures are stored in the Signatures folder.
Note: The V3 part may look different depending on which version of MacOS you have installed. For example, you might see V2 if you’re running an operating system older than MacOS 10.11 – El Capitan.
Step 3
In the Signatures folder, you will see each signature stored as a long number (Unique ID) with dashes, which ends with a .mailsignature extension.
Right-click on “AllSignatures.plist” > Open With > TextEdit.
Step 4
Take a look at the text inside the <dict> tags and you will notice the 2 <key>’s and <string>’s for each signature. The first key and string is the SignatureName. The second is the SignatureUniqueId. By looking at the string of the SignatureName key, find the <dict> tags for the signature that you want to remove.
Make sure you note down the last 4 digits of the string for the SignatureUniqueId key of the signature you want to remove.
Step 5
Select all the data inside the start <dict> and end </dict> tags, including the tags as well, and delete it.
Close the “AllSignatures.plist” file.
Step 6
Right-click on “AccountsMap.plist” > Open With > TextEdit.
You will notice an <array> with <string>’s inside it. Find the string that matches the SignatureUniqueId that you noted down earlier (last 4 digits) and remove the whole <string> line from the array.
Close the “AccountsMap.plist” file.
Step 7
Lastly, find the .mailsignature file which matches the SignatureUniqueId that you noted down earlier, and delete that file.
That’s it! The signature has been removed. You can now open Apple Mail and check that the signature is no longer there.
