How to Create a Signature in Apple Mail

by Sophie Southern

Creating an email signature is a simple way to make your messages look more professional while giving your blog, website or business more exposure. If you're on a Mac, Apple Mail lets you create multiple signatures with text and images and apply them to different email accounts. Once you create your email signatures, Mail also lets you choose which signature you want to apply to an email directly through the message window.

Step 1

Click the "Mail" icon in your Dock to open Apple Mail. Select "Mail" from the top menu bar, then select "Preferences."

Step 2

Click the "Signatures" tab and select the email account for which you want to create a signature.

Step 3

Click the "+" icon under the signatures window to add a new signature. Type a name for your signature. Mail will automatically include your name and email address in your signature.

Add the information you want to include in your email signature. Traditionally, you should include your name, title, company, email address and website. You can also include your mobile and office phone, or your account names on social networks.


  • If you want to include an image in your email signature, format it to the desired size. You will not be able to resize an image once you have inserted it into an Apple Mail signature. If you don't have a photo editing application, you can use Preview, which is located in your "Applications" folder, to resize images. You can use any size image for your email signature, but most email signatures use an image with a maximum edge of 200 pixels or less. Drag and drop images into the signature window to add them.
  • Drag and drop your signature to apply it to another email account. If you create more than one signature for an email account, the signature on top will appear as the default. You can drag and drop signature to reorder them.
  • Click the "Signature" tab when you write a message to choose between multiple email signatures.
