How to create and manage signatures in Apple Mail
Apple Mail lets you create multiple signatures and assign a different one to each email account. This guide covers creating, assigning and deleting signatures, plus how to include a logo correctly.
A signature is text added automatically to the end of every email you send. Apple Mail lets you create multiple signatures and assign a different one to each email account.
These steps are for the Mail app on macOS 26 (Tahoe). Earlier versions are very similar, with Settings appearing as Preferences.
Open the signatures settings
- Open Mail, then click Mail in the menu bar and select Settings (or Preferences on older macOS versions).
- Click the Signatures tab.
The window has three columns: your accounts on the left, the signatures belonging to the selected account in the middle, and the editor for the chosen signature on the right.
Add a new signature
- In the left-hand column, click the account you want the signature to belong to, or click All Signatures if you want it available to every account.
- Click the + (plus) icon below the middle column.
- Give the signature a name in the middle column, then click into the right-hand pane and type your signature.
The signature is saved as you type - there is no separate save button.
Assign a signature to an account
Creating a signature does not automatically apply it. To choose which signature is added to new messages for an account:
- Select the account in the left-hand column.
- At the bottom of the window, use the Choose Signature dropdown to pick the default signature for that account.
If you set this to At Random or In Sequential Order, Mail rotates through all signatures belonging to that account rather than always using the same one.
You can also change the signature on an individual email as you write it, using the Signature dropdown in the message window.
Delete a signature
- Select the signature you want to remove in the middle column, then click the - (minus) icon.
- Confirm when prompted. This permanently removes the signature and cannot be undone.
If you manage several email addresses, giving each account its own tailored signature keeps your correspondence consistent without having to pick the right one every time you write.
A note on logos and images
Before adding a logo or image to your signature, it is worth knowing that embedding the image directly causes problems - it attaches a copy to every email you send, which can make your messages look broken to recipients and quickly consumes mailbox space. There is a better way to include a logo. We cover the whole subject, including how to do it properly, in our separate guide to email signatures and images.
