January 8, 20266 min read

Why Your Email Signature Matters

Think about how many emails you send each day. 10? 50? 100? Each one is an opportunity to make an impression. A professional email signature:

  • Builds credibility and trust
  • Makes you easy to contact
  • Promotes your brand consistently
  • Can drive traffic and conversions
  • Shows attention to detail

Yet most people either have no signature, a messy one, or one that hasn't been updated in years. Let's fix that.

The 10 Tips

1

Keep It Concise

Your signature should be easy to scan in seconds. Include only the most important contact details—name, title, company, phone, and one or two links. Anything more creates clutter.

Do this

3-4 lines of essential contact info

Avoid this

10+ lines with multiple quotes and disclaimers

2

Use a Professional Photo

A professional headshot helps recipients put a face to your name and builds trust. Keep it small (around 80-100px) and use a recent, professional image.

Do this

Clear headshot with neutral background

Avoid this

Vacation photo, group shot, or cartoon avatar

3

Include Your Title and Company

Your title establishes credibility. Stick to your primary role—listing multiple titles looks unprofessional and confusing.

Do this

John Smith | Senior Developer at TechCorp

Avoid this

John Smith | CEO/Founder/Entrepreneur/Visionary

4

Make Contact Info Clickable

Clickable phone numbers and emails make it easy for mobile users to contact you directly. One tap vs. copy-paste can make the difference in getting a response.

Do this

Phone number and email as mailto:/tel: links

Avoid this

Plain text that requires copy-paste

5

Limit Social Media Icons

Include only platforms where you're active and where connecting would benefit the recipient. LinkedIn is usually essential; others depend on your industry.

Do this

2-3 relevant professional profiles

Avoid this

Every social platform you've ever joined

6

Use Brand Colors Sparingly

Brand colors add personality, but overuse looks unprofessional. Use them for dividers, icons, or your name—not entire paragraphs of text.

Do this

One or two accent colors for key elements

Avoid this

Rainbow of colors making text hard to read

7

Choose Readable Fonts

Web-safe fonts display consistently across all email clients. Fancy fonts may not render correctly and can look like gibberish to recipients.

Do this

Arial, Verdana, or other web-safe fonts

Avoid this

Decorative or script fonts

8

Add a Call-to-Action

A single, relevant CTA can drive engagement. Whether it's booking a meeting, visiting your portfolio, or downloading a resource—give people a clear next step.

Do this

'Schedule a call' or 'View our latest report'

Avoid this

Multiple competing CTAs or none at all

9

Test Across Email Clients

Email signatures render differently in various clients. Test yours by sending to different email addresses to ensure it looks good everywhere.

Do this

Verified in Gmail, Outlook, and Apple Mail

Avoid this

Only tested in your own email client

10

Include Legal Requirements

Some industries require specific disclosures. If needed, keep them brief or link to full terms. Don't let legal text overwhelm your signature.

Do this

Required disclaimers in appropriate contexts

Avoid this

10-paragraph legal disclaimer on every email

Bonus: What NOT to Include

Just as important as knowing what to include is knowing what to leave out:

  • Inspirational quotes — They're cliché and unprofessional in business contexts
  • Animated GIFs — They increase file size and can be distracting
  • "Sent from my iPhone" — Remove default mobile signatures
  • Fax numbers — Unless you actually use fax regularly
  • Multiple phone numbers — One direct number is usually enough
  • "Think before you print" — Outdated environmental disclaimers

Pro Tip: Create Multiple Versions

Consider having different signatures for different contexts: a full signature for first-time contacts, a brief one for ongoing conversations, and a personal one for less formal emails.

Quick Checklist

Before you finalize your signature, run through this checklist:

  • Name and title are clear and current
  • Contact info is accurate and clickable
  • Photo (if used) is professional
  • Links work correctly
  • Design is clean and readable
  • Tested in multiple email clients
  • Mobile-friendly layout
