Email Signature Design Tips: What to Include and What to Skip

A great email signature balances professionalism with personality. Here's a practical guide to designing one that works across every email client and device.

What to Include

Essential Elements

• Full name - First and last name, always
• Job title - Helps recipients understand your role
• Company name - Unless you're a solopreneur with a personal brand
• Phone number - One primary number, two at most
• Email address - Optional since it's in the email header, but helpful for forwarded messages

Recommended Additions

• Company logo - Keep it under 150px wide for clean rendering
• LinkedIn profile - The most universally relevant social link for professionals
• Website URL - Your company or personal site
• Call-to-action - A button for booking meetings, viewing a resource, or visiting a landing page

Optional (Use Sparingly)

• Profile photo - Great for client-facing roles, but not necessary for everyone
• Additional social links - Only if relevant to your role
• Pronouns - A welcoming touch that many professionals appreciate
• Address - Useful for businesses with physical locations

What to Skip

Things That Hurt More Than They Help

• Inspirational quotes - They may seem personal, but they look unprofessional and take up space
• Animated GIFs - Most email clients block them, and they're distracting when they do play
• Confidentiality disclaimers - Unless legally required, they add bulk without legal weight
• Multiple font styles - Stick to one font family. Mixing fonts looks chaotic
• Background colors or images - Email client support is inconsistent and they often break
• Vcard attachments - They show as attachments, confusing recipients and triggering spam filters

Design Principles

1. Hierarchy Matters

Your name should be the most prominent element, followed by your title. Contact details should be secondary. Use font size, weight, and color to create visual hierarchy.

2. Color Restraint

Use a maximum of 2-3 colors. Your brand's primary color for accents, a neutral for body text, and optionally a secondary color for subtle details. Avoid neon or overly bright colors.

3. Whitespace Is Your Friend

Don't cram everything together. Adequate spacing between elements makes your signature scannable and professional. A signature that breathes is easier to read.

4. Align Everything

Left-aligned text is the safest choice for email signatures. Centered text can look odd in email contexts where the surrounding content is left-aligned. Whatever alignment you choose, be consistent.

5. Test Across Clients

Your signature will look different in Gmail vs Outlook vs Apple Mail. The safest approach is to use HTML tables for layout (not CSS flexbox or grid) and inline styles. Tools like Signature Studio handle this automatically.

Sizing Guidelines

• Logo: 100-150px wide, optimized for web (PNG or JPEG under 50KB)
• Profile photo: 60-100px, circular or rounded shape
• Social icons: 20-24px, consistent style (all filled or all outlined)
• Total width: Keep under 600px for mobile compatibility
• Font sizes: 14-16px for name, 12-13px for details, 10-11px for fine print
