How to create a two-column signature in Mac Mail


Email signatures are a crucial part of professional communication. They help to create a lasting impression on your clients and colleagues and can be used to convey important information about your company or personal brand. While many email clients offer basic signature customization options, Mac Mail allows users to create a two-column signature, which can help to make your signature more visually appealing and functional. In this article, we’ll take a closer look at how to create a two-column signature in Mac Mail.

Step 1: Open Mail Preferences

To get started, open the Mail app on your Mac and click on the “Mail” menu in the top left corner of the screen. From the drop-down menu, select “Preferences” to open the Mail Preferences window.

Step 2: Create a New Signature

In the Mail Preferences window, select the “Signatures” tab. Here, you will see a list of your existing signatures, if you have any. To create a new signature, click on the “+” icon at the bottom of the list.

Step 3: Name Your Signature

After clicking on the “+” icon, a new signature will appear in the list. By default, it will be named “Untitled.” To give your signature a meaningful name, double-click on the name to edit it. For example, you might name your signature “Work” or “Personal.”

Step 4: Design Your Signature

Now it’s time to design your two-column signature. To create a two-column layout, you will need to use tables. Here’s how to do it:

  • Click on the “HTML” button in the signature editing window. This will open a new window where you can enter your HTML code.
  • Copy and paste the following code into the HTML window:

<table style=”border-collapse:collapse;width:100%;font-family:Arial,sans-serif;”>
<td style=”vertical-align:top;width:50%;”>
First column content goes here.
<td style=”vertical-align:top;width:50%;”>
Second column content goes here.

  • Customize the code to fit your needs. Replace “First column content goes here” and “Second column content goes here” with your own content. You can add images, links, and formatting to your signature by using HTML tags.

Step 5: Save Your Signature

After designing your signature, click on the “Save” button to save your changes. Your new signature will now appear in the list of signatures in the Mail Preferences window.

Step 6: Assign Your Signature to an Account

To use your new signature in your emails, you will need to assign it to an email account. To do this, go to the “Account Information” tab in the Mail Preferences window and select the email account you want to use your new signature with. In the “Signature” dropdown menu, select the signature you just created.

Step 7: Test Your Signature

Once you have assigned your signature to an email account, it’s important to test it to make sure it looks and functions the way you want it to. Send a test email to yourself or a colleague and check to see that your two-column signature appears correctly in the email.

Tips for Designing a Two-Column Signature

Now that you know how to create a two-column signature in Mac Mail, here are a few tips to help you design an effective and visually appealing signature:

  1. Keep it Simple

While a two-column signature can help to make your signature more functional, it’s important to keep it simple and easy to read. Avoid using too many colors, fonts, or graphics, as this can make your signature appear cluttered and unprofessional.

  1. Use Tables to Create Columns

Tables are the best way to create columns in your signature. As we mentioned earlier, you can use HTML code to create a table with two columns. Tables provide a more structured way to organize your signature content, and they can help to ensure that your signature looks consistent across different email clients.

  1. Include Your Contact Information

Your signature should include your contact information, such as your name, job title, email address, and phone number. This makes it easy for people to get in touch with you, and it also helps to reinforce your professional identity.

  1. Add Social Media Links

If you have social media accounts that are relevant to your professional life, such as LinkedIn or Twitter, consider including links to these accounts in your signature. This can help to expand your professional network and make it easier for people to connect with you on different platforms.

  1. Use Images Sparingly

Images can add visual interest to your signature, but they can also increase the file size of your emails and cause them to load more slowly. If you do use images in your signature, make sure they are optimized for the web and are not too large.

  1. Keep Mobile Devices in Mind

Many people check their email on mobile devices, so it’s important to make sure your signature is mobile-friendly. This means using a font size that is easy to read on a small screen, and avoiding complex layouts that may not display properly on mobile devices.


Creating a two-column signature in Mac Mail can help to make your signature more functional and visually appealing. By using tables to create columns, you can organize your signature content in a way that is easy to read and navigate. Remember to keep your signature simple, include your contact information, and test it on different devices to ensure it looks and functions correctly. With these tips in mind, you can create a signature that helps to reinforce your professional identity and makes a lasting impression on your clients and colleagues.
