How To Make Custom Stationery

I have been looking for a way to make my own stationery since I heard Leopard would allow us to put stationery in I found a really good tutorial over at He goes to really good depth on his tutorial. Take a look at the article here.


UPDATE: It looks like this article is no longer online. The link is dead and forwarding to  a dead link.

I have added the text and comments from the Internet Archive Wayback Machine July 5th 2008 below.

This post will outline everything someone will need who wants to start designing new Stationery for Mail in OS X Leopard. Hopefully, this will turn into an ongoing series about Stationery in Mail.

First Attempt at Skinning the Air Mail Stationery

What you will need to create new Stationery for Mail:

  • OS X 10.5 Leopard
  • XCode Installed
  • Photoshop (or other Image Editor capable of editing .jpg and transparent .png)
  • HTML / XML Editor
  • Package Maker (installed w/ XCode)

Do not overwrite existing files. If you wish to the modify existing files, backup the originals before changing anything!

The default Stationery you see in Mail is stored in a folder at the following location:

/System/Library/Application Support/Apple/Mail/Stationary/Apple/Contents/Resources/

If you navigate to this folder, you will notice a file called TableofContents.plist. This file contains the XML necessary for to list the Categories of Mail Stationery.

Notice how each Category has it’s own Folder? By default there are Announcements, Birthday, Photos, Sentiments, and Stationery Folders. If you click on one of these folders, you will see it has it’s own directory structure: /Announcements/Contents/Resources. You will find the the actual stationery in the Resources folder for a specific Category.

There are two oddball files among the Stationery, another TableofContents.plist and an English.lproj Folder (I imagine for others running Leopard in other languages this folder may change, can someone confirm?). TableofContents.plist here is another XML document that lists the Category’s Stationery in a format can understand. Does anyone know what the Stationery ID parameter in this file might be for? How can I create a new Stationary ID or a new piece of Stationery? The English.lproj folder contains a file called DisplayName.strings. In this file there is a comment that says: “Stationery category name as appears in the stationery selection pane in the New Message window after clicking Show Stationery toolbar item.”

If you go back to the Resources folder and Ctrl+Click on a .mailstationery file, you can select Show Package Contents from the menu. This will open the Stationery’s Directory Structure which is the same: /Stationary/Content/Resources/. Here you will find the files that make up a piece of Stationery in Mail.

There will most likely be the following basic files:

  • bg_pattern.jpg : The Background Image
  • top.jpg : Header Image
  • bottom.jpg : Footer Image
  • content.html : The HTML Template
  • Description.plist : The XML File Necessary for Interactivity in
  • English.lproj folder : Contains DisplayName.strings (file that names the Stationery for
  • thumbnail.png : The Thumbnail for the Selection Screen in Mail

Photo Stationery may have the following:

  • Mask1.png : The Mask for Drop Zones
  • placeholder1.jpg : The Placeholder Image for Drop Zones
  • banner.jpg : Usually the Background for the Masked Drop Zones
  • frames.png : The Template for the Drop Zones

The Workflow:

Do not overwrite existing files. If you wish the modify existing files, backup the originals before changing anything!

  • Create New Folder for “Custom” Stationery in the Resources folder, give it the Directory Structure /Content/Resources/
  • In this folder, make a file called TableofContents.plist. You will need to enter XML data here for the Individual Stationery inside the “Custom” Category. Project Folders and eventually Packages will go in this folder. An English.lproj folder with DisplayName.strings (for the Category name) must be in this folder as well.
  • Make a New Folder for the new Stationery and give it the same directory structure: /Content/Resources/
  • This is the folder you will place the HTML template (content.html), XML template (Description.plist), all images, and the English.lproj folder with DisplayName.strings (Name of the individual Stationery)
  • Use Package Maker to create a Package for the Stationery (must have .mailstationary as a filename and the correct Directory Structure)
  • Backup TableofContents.plist in /System/Library/Application Support/Apple/Mail/Stationary/Apple/Contents/Resources/
  • Add new lines in TableofContents.plist for the new Category

Can anyone tell me what that the Stationery ID is for in TableofContents.plist and how to create unique Stationery IDs for new Stationery and is this necessary?

If anyone ends up creating new Stationery because they read this tutorial, I would gladly post custom templates on

What did you learn in this post?

Or did it leave you with further questions?

    Bogus link. No tutorial just a parked page.

    Dave thanks for letting me know that the link is dead. I have taken the time to go get the text from the Internet Archive Wayback Machine to try and make this post more complete.

    Thanks for updating this post! I’m in the process of creating my own mail stationery and this has been helpful. I found from a Google search looking for tips to make my own stationery. I think I’ll have to bookmark the site, looks like there’s lots of good stuff here!

    You can save simple versions of custom stationery directly from I think that when you do this it most likely creates a StationeryID for your custom creation, but I haven’t confirmed this.

    Check out the Apple Pro Tip on this:

    in the content.html file I want to add a customized signature. I don’t want the image to show as an attachment but a part of the template itself. When I add the image and open in mail, it says missing plugin. I’ve use jpg, png, and psd. Any solutions as to which plugin is needed?

    To generate a unique ID, open and at the prompt type uuidgen. It gives a Unique ID you can use for your new template. Hope this helps

    If you used this great tutorial to create your own stationery and have upgraded to Mountain Lion, and want to make edits or add new templates, you’ll find that your “Custom” files have moved to a secret undisclosed location. Here’s the new path in hopes that it will save others the hours of hunting it took me to find it:

    ~/Library/Containers/ Support/Mail/Stationery/Apple/Contents/Resources/Custom

    Phew. To find your user library, hold down the Alt/Option key and select Go >Library in the Finder menu.

    The path to default Mail stationery has moved as well:

    Library/Application Support/Mail/Stationery/Apple/Contents/Resources

    Brilliant. This had been driving me bonkers for a week.

    Over the years I’ve received a lot of stationery that were printed with less than expected quality. Last year my company in Palm City FL, printed some stationery with PCA Delta and they were great. I’ve been printing with them ever since. If you need stationery printed go to I strongly recommend them.
