Why a professional email signature design is important for your brand

An email signature design is a structured block of text and imagery placed at the end of an email. It features key contact information such as your name, job title, company logo, and website link.

From a marketing perspective, professional email signature design helps:

• Promote campaigns and events with clickable banners

• Drive website traffic via hyperlinked logos and CTAs

• Encourage social engagement with icon links

• Reinforce credibility through certifications, awards, or disclaimers

It also plays a vital role in regulatory compliance. Industries like finance, legal, and healthcare often require disclaimers to meet standards such as GDPR, HIPAA, or SOC 2. A properly structured signature ensures these elements are consistently applied reducing risk without burdening IT.

Most importantly, modern designs ensure consistent rendering across devices and email clients. That means your brand stays professional and compliant everywhere communication happens.

Key elements of a well-designed email signature

When designing a professional email signature, consistency, clarity, and alignment with your brand identity are key. Whether you're creating an email signature for a sales executive, a CEO, or a customer support agent, the core elements should remain structured and purposeful.

Here are the essential components every effective email signature design should include:

1. Contact information 

Your email signature block should start with clear, up-to-date contact details:

• Full name

• Job title

• Phone number

• Email address

• Company website (hyperlinked)

2. Company logo 

Add a professionally scaled and hyperlinked logo to visually reinforce brand recognition.

• Recommended size: Max width 200px

• Link: Direct to your homepage or a campaign landing page

3. Social media icons  

Include social media icons linking to your official channels.

• Limit to 3–4 platforms to avoid clutter

• Always use current platform logos (LinkedIn, X (formerly Twitter), YouTube, Instagram)

• Link icons directly to each profile

4. Email banners  

Use email banners in your signature design to promote products, content, events, or offers.

• Add beneath contact info for visibility

• Use eye-catching designs with one clear CTA

• Ensure banners are responsive across devices

5. User photo 

Add a clean, professional photo image to personalize communication.

• Ideal for sales, client-facing, or remote roles

• Size recommendation: 50px–100px square

• Keep background neutral and lighting natural

6. Email disclaimer 

Critical for businesses in regulated industries (finance, legal, healthcare, etc.).

• Place at the bottom of the signature

• Use smaller font size (8–10pt)

• Tailor email disclaimers to regions or departments using dynamic fields if possible

7. Meeting booking links 

Make it easy to connect by embedding a scheduling link.

• Popular tools: Microsoft Bookings, Calendly, Chili Piper

• Use as a text link or CTA button: “📅 Book a Call”

8. One-click surveys 

Want fast feedback from customers or clients? Add simple satisfaction icons (smileys, stars, thumbs up) linked to one-click surveys.

• Ideal for customer support or client-facing teams

• Use platforms like SurveyMonkey, Google Forms, or Exclaimer’s built-in feedback tools

9. Awards, certifications, and trust seals

Boost credibility with recognized achievements.

• ISO certifications

• Industry awards

• Security badges (SOC 2, Cyber Essentials)

Which type of email signature design format is best?

Before you start designing your email signature, it’s important to choose the right format. The layout and technology behind your signature will affect how it appears across email clients, devices, and even in reply chains.

Here are the three main types of email signature formats and when to use them:

1. Plain text signatures

Plain text email signatures are simple, universal, and compatible with all email clients. They contain only unformatted text, usually limited to:

• Name

• Job title

• Company

• Contact details

• Disclaimer (if required)

2. Image-only signatures

Image-based signatures use a single image (or multiple images) to represent the entire signature block. These often look great in design but are risky in execution.

3. HTML email signatures (recommended)

HTML email signatures provide the most flexibility and customization. They support a combination of text, images, logos, clickable links, and even promotional banners, allowing for a professional and visually appealing design.

Do more with your email signature designs

A good email signature does more than share contact details. When set up right, it becomes a lightweight branding asset. This helps with recognition, accessibility, and even campaign performance.

Here’s how to make your email signature block design work harder:

Best practices for email signature design

Designing the perfect email signature block is all about balancing style, functionality, and readability.   

Follow these best practices to ensure your signature looks professional and works seamlessly across devices and email clients:

1. Use properly sized images

Images play a big role in a branded email signature. To keep your signature lightweight and crisp:

• Logos: Max 200x200px

• Banners: Between 320–600px wide (450px is ideal)

• Photos: Headshots should be 50–100px square

• Use hosted images, not embedded ones to prevent them from showing as attachments.

• Always add alt text for accessibility and image fallback.

2. Stick to brand colors

Color reinforces brand identity, but it must be used carefully:

• Use hex color codes (e.g., #005EB8) for consistency

• Limit your palette to 2–3 colors max

• Avoid background colors as they may not render correctly in dark mode or mobile

• Use color to highlight key elements like CTAs or social icons

3. Use web-safe fonts

Choose email signature fonts that display reliably across all email clients:

• Recommended fonts: Arial, Helvetica, Georgia, Verdana, Tahoma

• Use one main font + one fallback font

• Keep font sizes between 11pt–13pt

• Avoid script or decorative fonts — they often break or appear unprofessional 

4. Structure your layout with tables

To create a clean and mobile-friendly layout:

• Use HTML tables for layout (not divs) — tables display more consistently across Outlook, Gmail, Apple Mail, etc.

• Align elements in logical rows or columns (e.g., name/title, then contact, then links)

• Make use of white space as it helps with scannability and prevents clutter

• Avoid bullets and unnecessary design elements 

5. Design for mobile responsiveness

With more than half of business emails read on mobile:

• Use single-column layouts

• Avoid heavy graphics

• Compress images to load quickly

• Test on major mobile email clients (Outlook mobile, Gmail app, Apple Mail)

Examples of the best email signature designs 

Whether you're designing email signatures for executives, sales teams, or internal staff, the layout and elements should reflect your brand, audience, and communication goals.

Here are email signature design examples organized by profession, format, and occasion—each optimized for visual clarity, mobile responsiveness, and branding.

By profession

Use job-specific email signature block designs to tailor tone, contact details, and CTAs based on audience expectations.

By design

Different formats suit different tech stacks, industries, and user preferences. Choose a design that supports your goals and works across platforms.

By seasonality or campaign

Use timely, seasonal, or campaign-based email signature designs to keep content fresh and drive action.

How to design the best email signature in 9 steps

Designing the perfect email signature doesn’t have to be complicated. Follow these steps to create a professional, branded signature that enhances communication, reinforces brand identity, and functions seamlessly across devices.

1. Define your purpose and audience 

Start by identifying what you want your email signature to achieve:

• Brand recognition?

• Lead generation?

• Compliance?

• Personalization?

Also consider:

• Who will use it: Will it be used company-wide or only by specific teams? 

• Who the recipients are: Will it be seen by prospects, customers, or other stakeholders? 

2. List essential information 

Keep your email signature block simple and scannable. Include only key contact information:

• Full name

• Job title 

• Company name 

• Phone number

• Email address 

• Company website (hyperlinked) 

3. Incorporate branding elements 

Your email signature should align with your company’s visual identity. Key branding elements include: 

• Company logo (clickable, hosted, properly sized)

• Brand fonts and colors (web-safe, accessible)

• Tagline or call-to-action (“Book a demo”, “See pricing”) 

4. Choose the right layout 

The structure of your email signature block design should prioritize readability and balance. Group related items together, such as: 

• Name and job title at the top 

• Contact details in the middle

• Branding elements (logo, tagline, or CTA) toward the bottom 

5. Use the right tools for design

Select the best tool based on your skills and design needs: 

• HTML coding: Code your HTML email signature using tags such as <head> and <footer>. 

• Email signature generators: Tools like Canva and HubSpot make it simple to create professional designs for individual users. 

• Professional design tools: Create custom designs using tools like Photoshop, Illustrator, or Figma. 

• Email signature software: Platforms like Exclaimer ensure centralized management while offering automation, analytics, integrations, and additional marketing features. 

6. Optimize for mobile and email clients 

Ensure your email signature is mobile-responsive and displays correctly across different devices and platforms like iOS for iPhone. Key considerations include: 

• Use single-column layout

• Scale images appropriately

• Avoid wide banners or embedded elements

• Test on Gmail app, Outlook mobile, and Apple Mail

7. Test the links and functionality 

Before deployment, conduct a full functionality check to ensure: 

• Click every link

• Hover over icons

• Check banner images load correctly

• Confirm phone numbers are tappable

8. Add legal disclaimers 

In industries like finance, healthcare, and law, a legal disclaimer is non-negotiable.

Best practices:

• Keep it short and readable

• Place it below the main signature block

• Use a smaller font size

• Update it regularly based on your legal team’s guidance 

9: Monitor and update regularly 

Don’t set it and forget it. Make reviewing your email signature part of your brand hygiene routine:

• Revisit quarterly or after major company updates

• Check for outdated links, photos, or job titles

• Track performance if using banners or CTAs

11 email signature design examples and tips 

Visually, technically, and professionally–the best email signature​ designs​ should work in every sense of the word.

To inspire you, we’ve put together 11 email signature design examples and tips with practical examples. Use these ideas to create a signature that helps your company stand out.  

1. Include essential contact information 

A great email signature presents all contact details in a clean, easy-to-read format. Using a simple grid layout ensures the information is clear and organized.

Stick to professional details only—avoid personal quotes, excessive links, or multiple phone numbers that can create clutter.

The example above demonstrates an effective email signature, featuring essential contact information, a corporate URL, and a user photo. Including a photo adds a personal touch and helps make communication feel more engaging.

2. Enhance engagement with social media icons

Replace long URLs with clean, professional social media icons.

• Limit to 3–4 platforms max

• Always link to corporate profiles (not personal accounts)

• Use the latest icon sets and maintain consistent sizing

This email signature design includes four social media icons, striking the perfect balance. It saves screen space, enhances visual appeal, and keeps the focus on the main company logo.

3. Ensure mobile optimization 

With over half of emails read on mobile:

• Use single-column designs

• Limit horizontal content

• Test on Outlook Mobile, Gmail App, and Apple Mail

• Ensure all text is legible at small screen sizes

• Use hosted images (avoid embedded ones that appear as attachments)

Here’s an example of an email signature designed for mobile optimization. The template includes all the key information while keeping the focus on the main email message.

4. Use different signatures for different contexts 

Use different email signature designs for:

• First-time outreach: Full signature with banner and CTA

• Follow-ups / replies: Minimalist version with just name, title, and phone

• Internal emails: Streamlined design, no banners or social links

The first signature design showcases a sophisticated and striking layout to create a strong initial impression.

Subsequently, a second signature is used for any follow-up replies to streamline communication.

5. Using colors effectively 

Too much color can make a signature look amateur. Stick to your brand palette:

• Primary color: Headers, icons, name

• Accent color: CTAs, dividers

• Text: Stick to black, gray, or navy for readability

This sleek email signature template looks great on a white background. It highlights the brand's creativity while remaining subtle and professional.

6. Choosing the right image format 

When using images (e.g., logos, banners, headshots):

• Use PNG for logos (transparent background, high quality)

• Use JPEG for staff photos (smaller file size)

• Avoid SVG — not all email clients support them

• Host images externally (don’t embed)

• Avoid large image files — keep total signature size under 50 KB.

This email signature incorporates multiple images, including a corporate logo, awards, and feedback icons. Each image is placed precisely using HTML, ensuring the signature looks polished and professional.

7. Promote marketing activities with email banners

Email signature banners can promote:

• New products

• Blog posts

• Webinars

• Case studies

• Seasonal offers

Place banners below contact details and include UTM parameters for tracking.

Here’s an example of an email banner promoting an upcoming event. Positioned just below the contact details, it grabs attention and encourages engagement.

8. Consider internal email signatures  

Don’t waste internal email real estate. Use internal email signatures to:

• Share company news

• Highlight employee recognition

• Promote events

• Link to HR resources

Keep these minimalist: no social media links or external CTAs needed. 

You can use internal email signatures to promote seasonal events or share important updates with employees. Adding a small, tailored message at the end of your email is an easy and effective way to reach all employees.

9. Gather customer feedback efficiently

Add a CSAT, NPS, or emoji-style survey to the bottom of your signature.

Benefits include:

• Instant customer feedback

• No need for follow-up

• High response rates

• Real-time insights

This template uses stars to collect customer feedback. Universal icons like these are easy to understand, no matter the language.

10. Use a strong call-to-action  

Turn your signature into a conversion tool.

Example CTAs:

• “Book a demo”

• “Download the report”

• “Refer a colleague”

• “Chat with support”

Use clear, visually distinct buttons. Don't overdo it—one CTA per signature is ideal.  

This template includes a call-to-action button that lets recipients book a meeting with the sender. This button then links to the sender’s calendar.

11. Maintain legal compliance  

Opinions on  email disclaimers are subjective. However, the main reason a company uses Exclaimer is for compliance needs.  

• Place disclaimers in a smaller font below the main signature

• Separate it visually to prevent distraction

• Keep the tone professional, not overly legalistic

The best email signature designs like the above example place the disclaimer apart from the signature. It doesn’t interfere with the rest of the design as a result. The font size is small and can be easily read against light backgrounds.

What should you use to design your email signature?

Companies have a wide range of tools and methods available to design professional email signatures. These can vary from simple email signature builders to advanced software that integrates with email platforms for centralized management. 

Below is a breakdown of the most common email signature design tools and when to use each:

1. Email signature management software (best for companies)

An email signature management solution offers a centralized platform for designing and updating signatures for all employees. This is the gold standard for modern businesses.

Best for:

• Organizations with 10+ employees

• IT or Marketing teams managing branding at scale

• Industries with legal or regulatory requirements

Key features:

• Centralized admin dashboard

• Directory integration (Microsoft Entra ID, Google Directory)

• Role-based access for IT/Marketing

• Banner scheduling, analytics, and compliance tools

• Mobile and cross-platform support

2. HTML coding (flexible but technical) 

If you’re familiar with HTML code, you can design your own email signature using basic coding techniques.

Best for:

• Developers or designers

• Complex, custom layouts

Challenges:

• Requires ongoing maintenance

• Can break in certain email clients

• Difficult to scale or update across teams

3. Graphic design software (high customization, low practicality)

Using graphic design software like Adobe Photoshop or Illustrator gives you more creative control.

Best for:

• Custom layouts or visual mockups

• Creating image-only signature mockups

But:

• Outputs are usually image-based (not ideal for email)

• Difficult to update or manage

• Poor deliverability and accessibility

4. Email signature generators (only for individuals)

Free email signature generators are a fast and simple way to make a professional email signature for individuals.

Best for:

• Freelancers

• Individual professionals

Limitations:

• No central management

• Not suitable for large companies

• Limited control over formatting across devices

5. Professional designers (great branding, higher cost)

If budget allows, hiring a professional designer can result in a unique and visually appealing email signature design.

Best for:

• Brand-first companies

• High-value personal signatures (e.g., C-suite execs)

Limitations:

• Requires clear specs for email compatibility

• Must still be coded in HTML or applied via a platform

• Ongoing updates will require more time or budget

Which method should you choose?

Mastering email signature design for your brand 

Email signatures might appear minor, but their impact on communication and brand identity is significant.

From placing your logo in front of customers to adding a CTA, a great email signature design creates impact. It transforms static communication into an opportunity to connect. 

Every email then becomes an opportunity to:

• Reinforce brand consistency

• Create visual recognition (logo, colors, typography)

• Drive engagement through clickable calls-to-action (CTAs)

• Showcase your brand’s professionalism and attention to detail

From bold, marketing-led designs to clean and compliant layouts, how you design your email signature speaks volumes about your business.

Make email a brand asset, not a blind spot

Marketing teams spend plenty of time on websites, social channels, and paid campaigns. Yet email, the channel employees use most, is often left out of the mix.

By standardizing and optimizing your email signature block design, you:

• Create brand alignment across all departments

• Ensure mobile and cross-platform consistency

• Unlock a new touchpoint for marketing, recruiting, or support

• Minimize risks related to poor formatting or outdated contact info
