Email Client Rendering Differences

Different email clients render HTML signatures differently. Understanding these differences helps you create signatures that look great everywhere.

Outlook (Windows)

Uses Microsoft Word's rendering engine. Most limited CSS support. Stick to basic table layouts and inline styles.

Gmail

Good CSS support but strips certain attributes. Supports most inline styles and basic HTML elements.

Apple Mail

Best CSS support among email clients. Supports most modern CSS properties including some CSS3 features.

Character Encoding

Always declare UTF-8 encoding in your template to ensure special characters render correctly across all clients.

Testing

Preview your signatures across multiple email clients using SigStudio's built-in preview tool before deploying.
