Less is more
The strongest signatures are restrained: a clear hierarchy, one accent color, and only the contact details that matter. Every extra element competes for attention and adds breakage risk.
Establish hierarchy
Make the name the most prominent line, the title and company secondary, and contact details tertiary. Size, weight, and color should guide the eye in that order.
Create a professional email signature in minutes
Use KeyStamp's AI Signature Studio to generate, customize, preview, and export email-safe signatures for your team.
Use a brand accent sparingly
A single brand-colored divider or title line ties the signature to your identity without overwhelming it. Avoid coloring entire blocks of text.
Keep it email-safe
- Table-based layout with inline CSS
- Hosted images with explicit width and height
- Web-safe fonts with sensible fallbacks
- Under ~600px wide
