Brand consistency

Your email signature is an extension of your brand. Every email your team sends is an opportunity to reinforce brand recognition and professionalism.

Brand Elements in Signatures

Logo Usage

  • Use your official logo, properly sized (150-200px wide)
  • Maintain proper spacing around the logo
  • Use PNG with transparency for clean backgrounds
  • Consider a simplified version for small sizes

Color Palette

  • Use your primary brand color for accents
  • Keep text in readable colors (black/dark gray)
  • Limit to 2-3 colors maximum
  • Use hex codes to ensure exact color matching

Typography

  • Stick to web-safe fonts for compatibility
  • Match your brand's font style (modern, traditional, etc.)
  • Use consistent sizing (name larger, details smaller)

Consistency Matters

When every employee has a different signature style, it looks unprofessional. Standardized signatures signal:

  • Organization and attention to detail
  • Professional, established company
  • Unified team identity
  • Brand awareness with every interaction

Creating Brand Guidelines

Document your signature standards:

  • Approved templates and variations
  • Color codes and font specifications
  • Logo files and placement rules
  • What can/cannot be customized
  • Who to contact for changes

Tip: Marketing should own signature design, but IT handles deployment. Collaborate to balance brand requirements with technical constraints.

Enforce brand consistency

Siggly ensures every signature matches your brand guidelines — employees can't go off-brand.
