Having trouble with disappearing signatures in Apple Mail? Let’s break down why this happens and how to fix it.

Why Does My Email Signature Keep Disappearing in Apple Mail?

Usually, the culprit is iCloud sync issues. When iCloud tries to sync Mail, it sometimes messes up the files needed for your email signatures. It might not recognize or sync them right.

As miroslavmajdak pointed out, when you make a new signature, it should save in a file called AccountsMap.plist. But sometimes, the actual signature file (named .mailsignature) doesn’t get created. This is why it doesn’t show up in your emails.

Where Is My Apple Mail Signature?

To understand why your signature disappears, it helps to know where Apple Mail keeps these files. They’re in a special folder in the system library. For each signature, there are three key files:

  • .mailsignature – This file holds your actual signature. If you have more than one signature, you’ll have multiple .mailsignature files.
  • .plist files – There are two kinds:
    • AccountsMap.plist – Tells which signatures go with which accounts.
    • AllSignatures.plist – A list of all your signatures.

Understanding the whereabouts of these files will be crucial in resolving the issue.
