Email Signature HTML Code: Complete Guide and Examples

Creating email signature HTML code requires understanding email client limitations and HTML best practices. This guide covers everything you need to know.

HTML for Email Signatures

Why HTML?

HTML allows for:

• Rich formatting
• Images and logos
• Links and styling
• Professional appearance

Email HTML Limitations

Email clients strip or modify:

• External CSS
• JavaScript
• Some HTML5 elements
• Complex layouts

Basic HTML Structure

Simple Text Signature

<p>John Smith</p>
<p>Chief Technology Officer</p>
<p>Email: john@company.com</p>
<p>Phone: +1 (555) 123-4567</p>

Signature with Styling

<table style="font-family: Arial, sans-serif; font-size: 12px;">
  <tr>
    <td style="padding: 10px;">
      <strong style="font-size: 14px;">John Smith</strong><br>
      Chief Technology Officer<br>
      <a href="mailto:john@company.com">john@company.com</a><br>
      +1 (555) 123-4567
    </td>
  </tr>
</table>

Inline Styles

Why Inline Styles?

Email clients strip external CSS, so use inline styles:

<p style="color: #333; font-family: Arial; font-size: 12px;">Text</p>

Common Styles

• Font-family: Arial, Helvetica, sans-serif
• Font-size: 11-14px
• Color: #333333 (dark gray)
• Line-height: 1.4-1.6

Adding Images

Image HTML

<img src="https://yourdomain.com/logo.png" alt="Company Logo" style="max-width: 200px; height: auto;">

Image Best Practices

• Use absolute URLs (https://)
• Include alt text
• Set max-width
• Optimize file size

Creating Links

Text Links

<a href="https://yourwebsite.com" style="color: #0066cc; text-decoration: none;">Website</a>

Social Media Icons

Use icon images with links:

<a href="https://linkedin.com/in/johnsmith">
  <img src="https://yourdomain.com/linkedin-icon.png" alt="LinkedIn" style="width: 24px; height: 24px;">
</a>

Table Layouts

Why Tables?

Tables provide better email client compatibility than divs.

Basic Table Structure

<table style="border-collapse: collapse;">
  <tr>
    <td style="padding: 10px;">Content</td>
  </tr>
</table>

Complete Example

Professional Signature HTML

<table cellpadding="0" cellspacing="0" style="font-family: Arial, sans-serif; font-size: 12px; color: #333;">
  <tr>
    <td style="padding: 10px 0;">
      <img src="https://yourdomain.com/logo.png" alt="Company" style="max-width: 150px; margin-bottom: 10px;"><br>
      <strong style="font-size: 14px; color: #000;">John Smith</strong><br>
      Chief Technology Officer<br>
      <a href="mailto:john@company.com" style="color: #0066cc; text-decoration: none;">john@company.com</a><br>
      <a href="tel:+15551234567" style="color: #0066cc; text-decoration: none;">+1 (555) 123-4567</a><br>
      <a href="https://yourwebsite.com" style="color: #0066cc; text-decoration: none;">www.yourwebsite.com</a>
    </td>
  </tr>
</table>
