Formatting Signatures in Email

Let’s look at email signatures in Microsoft Outlook and in Gmail, since these are the most common email tools that are used in the office by professionals. This can carry over into your personal life as well. I use several signatures, depending on what email address I am sending from or what the purpose of the email is. Rather than creating something new every time, I’ll show you here how to keep consistent messaging to your clients, coworkers, and other professional contacts!

An email signature functions as a digital business card, appearing at the end of your emails. A thoughtfully formatted signature can:

  • Enhance your professional image.

  • Reinforce your brand identity.

  • Provide quick access to your contact details.

  • Direct recipients to your social media, website, or other resources.

To make the most of this valuable space, your email signature should be clean, concise, and functional.

Microsoft Outlook offers a robust set of tools for designing email signatures. Here's a step-by-step guide to creating and formatting one:

Step 1: Access the Signature Settings

1. Open a new email

2. Click on the Signature Button in the Message tab

3. Select Signature from the menu.

Step 2: Create a New Signature

1. In the Signatures and Stationery window, click New.

2. Give your signature a name that you will reference (Out of Office, Client Follow Up, etc.)

3. In the text editor below, start designing your signature.

Step 3: Formatting Your Signature

Microsoft Outlook allows for rich-text formatting, so you can:

  • Choose fonts, sizes, and colors to match your personal or corporate style.

  • Add bold or italicized text for emphasis.

  • Insert images such as a company logo or your photograph.

  • Include hyperlinks to your website or social media profiles.

For consistency, use business-appropriate fonts like Arial, Calibri, or Times New Roman. Avoid overloading your signature with too many colors or fonts. What you see isn’t necessarily supported on the recipient’s end, so keep it simple. I’ve seen some wild choices which have made me wonder who exactly was on the other end of some emails!

Step 4: Assign the Signature

1. Choose which email account the signature applies to (if you manage multiple accounts).

2. Set the signature to appear automatically for new messages, replies, forwards, or all three.

Step 5: Test and Refine

Send a test email to yourself or a colleague to ensure the signature appears as intended. Adjust the layout or formatting if needed.

Creating and Formatting Signatures in Gmail

Gmail also provides an intuitive interface for crafting email signatures, though its customization options are somewhat more limited than Outlook's.

Step 1: Access the Signature Settings

1. Log into your Gmail account.

2. Select the button to compose a new email

3. Click the icon of a pen (insert signature)

4. Select Manage Signatures.

Step 2: Create a New Signature

1. Click the Create New button.

2. Enter a name for your signature and hit Create

3. Use the built-in editor to design your signature.

Step 3: Formatting Your Signature

The Gmail signature editor allows you to:

  • Choose font styles, sizes, and colors.

  • Add bold, italic, or underlined text.

  • Insert images, such as a logo or banner, using the image icon.

  • Add clickable links to your website or social media.

Gmail also supports drag-and-drop functionality for images, though these may appear as attachments to some recipients. Ensure your signature remains simple and visually appealing.

Step 4: Assign the Signature

1. Choose the default signature to use for new emails and replies/forwards.

2. Gmail allows you to apply different signatures for different accounts if you manage multiple addresses.

Step 5: Test and Refine

Send a test email to yourself or another Gmail account to preview your signature. Make any necessary adjustments to ensure it looks polished and professional.

Best Practices for Email Signatures

Whether you’re using Outlook or Gmail, following these best practices will ensure your email signature is effective:

  • Keep it concise: Limit your signature to 3–6 lines of text to avoid overwhelming recipients.

  • Include essential information: Name, title, company, phone number, email, and website are standard elements.

  • Use a professional design: Avoid decorative fonts or excessive colors.

    • I like to bold my name, italicize my title, and sometimes I get crazy and separate contact information with the pipe (|)

  • Optimize for mobile: Ensure your signature displays well on smartphones and tablets.

  • Test frequently: Email clients and devices may render signatures differently. Regular testing ensures consistency.

And if your company requires you follow a particular format, follow that format!

Formatting email signatures in Microsoft Outlook and Gmail is a straightforward process that allows you to present yourself or your organization in the best possible light. With just a bit of effort, you can create a professional, visually appealing, and functional signature that enhances your email communication. Whether you’re an individual professional or part of a corporate team, a well-crafted signature is a small detail that makes a big difference.
