Struggling to find practical guidance on email signatures?

This post has you covered, from HTML versus image designs to setup across different email clients.

Packed with tips and examples to help you create a standout signature in a few minutes.

Why You Need An Email Signature

A sharp email signature enhances your credibility - it's like a social media profile picture.

Think about it, would you respond to a message from a faceless profile on Instagram?

Probably not - the same principle applies to your emails.

Moral of the story?

What’s A Good Email Signature?

A strong email signature showcases your role and the key details your recipient is interested in.

At the bare minimum, your signature should include:

  1. Your First Name
  2. Your Position (what you do.)
  3. Contact Information other than your email (it’s a common but redundant practice.)
Customer Success Associate
(555) 123-4567

Bonus elements you can include:

  1. Logo/Photo: A small, high-quality company logo or headshot for recognition.
  2. Social Links: Only add the profiles you actively maintain.
  3. Portfolio/Web Link: A direct, clickable link to your work or website.
  4. Certifications/Awards.
  5. CTA: A short phrase encouraging action that align with your goals.
  6. Legal Disclaimer: A necessary, brief note for compliance in formal sectors.
  7. Quote/Motto: A short, professionally resonant quote to add a personal touch.

The paradox of choice (a psychological concept) suggests that too many options overwhelm your recipient - simpler is better.

Pick one or two bonus elements to ensure you don’t overload your recipient with information.

Email Signature Design Tips

High-Res Images

Make sure your images are clear, high quality & visible (even to people who have difficulty seeing!)

  • Tools for Compression: Adobe Photoshop, GIMP or free online tools like TinyPNG or to compress your images for faster loading time.
  • Tip: Use sharp, clear logos or headshots. The ideal size is around 300-400 pixels wide.
  • File Size: Use Adobe Photoshop, GIMP or free online tools like TinyPNG or to compress images to under 100 KB for faster loading times while maintaining image quality.

Color Scheme

  • Tools: Try Coolors or Adobe Color for palette selection.
  • Tip: Pick 2-3 colors (no more) that reflect your brand, with strong contrast for readability.

Here’s what the Coolors interface looks like, you can choose from existing palettes or generate your own.

Readable Fonts

  • Stick with clear, professional fonts like Arial or Helvetica.

Smart Spacing

  • Maintain balance between content and white space for an uncluttered look.

Streamlined Layout

  • Tools: Browse Canva or Adobe Spark for layout ideas.
  • Tip: Highlight key info (name, title, contact) in a scan-friendly order.

Functional Links

  • Ensure your website or social media links are clickable and current.

Mobile-Friendly Design

  • Tools: Test responsiveness with Email on Acid or Litmus.
  • Tip: Design for small screens—keep it legible and neatly arranged.

Legal Compliance

Utilize legal templates or professional advice for disclaimers - keep them concise and unobtrusive.

How To Create Your Email Signature

You have two primary options:

  • Image Designs (JPEG or PNG)
  • HTML

Fixed image signatures in emails offer consistent visuals across platforms but can be less flexible; they’re easy to create but aren't responsive on different devices and text isn't selectable.

On the other hand, HTML designs provide dynamic, customizable options with responsive layouts and clickable links.

However, they require HTML know-how, might display inconsistently across email clients, and face potential security restrictions.

Choose fixed images for simplicity and consistency, or HTML for flexibility and interactivity.
