How to Create an Email Signature: Quick Step-by-Step Guide
Creating a professional email signature for your company is not as simple as you might think. To ensure the design is consistent across the whole organization and the HTML email signature is displayed correctly in the most popular email clients, you will have to follow the steps below.
Step 1. Choose the Purpose and Information
First, decide why you need an email signature. Do you want to build your personal brand, generate leads, or keep a consistent look for your company? Then, choose the important details to include: your full name, job title, company, phone number, website, and any other key contact information. Keep it short and simple - don’t add too much information.

Step 2. Choose a Creation Method
Choose how to create your email signature based on your skills and needs. You have several options: use an email signature generator (the easiest choice for most people), use built-in tools in Gmail or Outlook, write HTML code, design it in Canva or Photoshop, or hire a freelancer. Pick the method that gives you the best mix of quality, time, and control.
Step 3. Design the Signature
Design your signature to match your professional image. Choose colors, fonts, and a layout that reflect your style. Include your logo, a professional photo if appropriate, social media icons, and a relevant call-to-action (CTA). Make sure the design is clean, balanced, and represents your brand effectively.
Step 4. Test It Across Email Clients
Testing is essential. Check how your signature appears in Gmail, Outlook, Apple Mail, and other popular clients. Test on both desktop and mobile devices, in dark mode, ensure all links are clickable, and verify that images load correctly. A poorly displayed signature can damage your professional impression.

Limitations of Email Signature Generators
Email signature generators are useful tools, but they have some limitations. Free versions usually have a small selection of templates, limited branding options, and may include watermarks or branded elements from the service. Many helpful features, like custom fonts, advanced analytics, banner rotation, or team management, are often only available in paid plans.
For individual users, the free or basic version is often enough. However, for teams and companies, it’s best to choose a generator that allows for centralized management. This option lets administrators control, update, and keep signatures consistent for all team members from one dashboard, saving time and ensuring consistent branding.
2. Create an HTML email signature
This method is best for users who want full control over their email signature's design and code. It is great for developers, designers, or anyone with technical skills who needs a highly customizable signature. However, you will need to know HTML and inline CSS, and you should test your signature carefully to make sure it looks good in different email clients.
Crafting your own HTML email signature
1. Understand your purpose
An HTML signature isn't just a visual element – it's a marketing tool – with backlinks to your website or social media, to boost traffic. Whether you use it for personal needs or business, you should clarify your goal. Knowing your goals helps you choose the right information to include.
2. Choose a tool
Several software options can help you create an HTML signature. Most offer similar functionalities, so pick one that suits your needs. Make sure also that the software supports your mail client, as there may be some surprises.
We at Newoldstamp work with all popular providers. We are welcoming you to make the signature of your dream.
3. Begin either with a free or paid option of an HTML email signature
Most software features both free and paid options. For example, free tools like HubSpot’s email signature generator offer core functionalities, like the option to add photos and additional contact links, as well as embed social media links and clickable CTA buttons. However, paid versions offer greater customization, allowing you to create a unique signature aligned with your brand.
For corporate needs, consider purchasing a package for multiple users.
4. Be selective about the information you provide
Do you remember your goals from step 1? Include only the relevant information. You should think over:
- your job title and company;
- corporate website or any other sites;
- phone number, email, post address (if applicable);
- social media profiles;
- Images (logos, headshots).
Most online generators provide dedicated fields for this information.
5. Fill in the required fields and copy an HTML email signature to your mail client
When you’ve decided on the information, insert it into the fields of your software. Upload photos and add links. Experiment with different designs to find one that aligns with your preferences or brand identity.
Finally, copy the generated HTML code and paste it into your email client. Send a test email to ensure everything displays correctly.
Pros of HTML Email Signatures
-
Full control over your signature template
If you or your developer are well-versed in HTML, the possibilities are limitless. You can bring any creative idea to life with your signature design.
-
Your signature can be edited at any time
Many email signature services offer subscription plans for a limited number of signatures per year. But if you want to modify your signature at any time for free, you should use HTML. Once you create your email footer, you won't have to pay anyone but will be able to edit it at any time. However, keep in mind that you will need to go through a somewhat large piece of code every time you want to change even a small bit of your signature, which brings us to the disadvantages of using HTML.
Limitations of HTML Email Signatures
-
You need to learn HTML
Learning something new is always good, but sometimes you don't have enough time. You might find yourself in a situation where you need a signature quickly, and learning HTML may not be achievable.
-
Hire a developer
If you're a busy professional with no spare time to master HTML or improve your coding skills, you need to start looking for people capable of doing your project. Finding a skilled web developer can be time-consuming, especially if you lack prior experience in hiring one.
-
Spend time on research
Email signatures can be displayed differently for various recipients due to the diverse tech requirements of different email clients. You'll need to invest time in understanding these requirements to ensure your signature appears as intended.
-
Spend time on testing
Remember that testing your signature across multiple email clients is necessary to ensure it maintains its appearance after being sent.
-
Preview issues on different devices
It's hard to imagine our life without mobile devices, especially smartphones and tablets. Many professionals use mobile devices for their business emails. Therefore, it's crucial to ensure that your email signature looks correctly on all types of devices. Over half of all mobile phones in the United States are smartphones, making it even more important to cater to this audience.
3. Design an Email Signature in Canva, Photoshop, or Another Design Tool
Design tools like Canva, Figma, Photoshop, and Adobe Illustrator are great for creating email signatures that look good. These tools let you decide on layouts, pick brand colors, and try out different styles.
But remember this important rule: do not use your signature as a single large image. While it may look great in the design tool, using it as one image can cause problems. Often, images do not load, links become unclickable, it may not work well on mobile devices, and it can trigger spam filters.
Pros of Using Design Tools
- Unleash Your Creativity
With tools like Canva, Figma, and Photoshop, you can create an email signature that looks great and fits your brand.
- Full Control Over Your Signature Template
You control every part of your signature, like the layout, colors, fonts, logo placement, icons, banners, spacing, and overall style. This helps you design a signature that matches your brand identity.
- Edit Your Signature Anytime
You can change your design whenever you need to, without extra costs or relying on others. Just update the file and export a new version.
Why You Shouldn’t Use One Big Image as Your Signature
Creating your email signature as a single image may look nice, but it has several important problems:
- Images might not show up
Many email programs block images by default. This means recipients often have to click "Download images" to see your signature.
- It shows as an attachment
Instead of appearing in the email, the signature can come as a separate file attached to the message.
- Poor experience on mobile device
A large image may not adjust well to smaller screens, making it hard to read on smartphones.
- No clickable links
You can't click on social media icons, website links, calls to action, or email addresses, which reduces their effectiveness.
- Makes emails larger
Big image files increase the overall size of your emails, which can slow them down.
- Higher chance of being marked as spam
Emails with large images are more likely to be caught by spam filters.
4. Create an Email Signature in a Text Editor: Why It’s Not Recommended
Another popular way of designing a professional signature for emails is by using a Microsoft Word template. So, how to make a signature in Word? You probably heard of Word Rendering Engine by Microsoft for creating the HTML code. The produced code looks the same across almost all Microsoft products like Outlook, Word, and Excel.
For instance, if you copy your Word email signature template and paste it directly into a message in Outlook, it will be appropriately displayed in most versions of Outlook. Although this method is free, some specific things will go wrong if you choose to follow this approach.
Common Problems with Text Editor Signatures
| Problem | Why It Happens | How to Avoid |
|---|---|---|
| Formatting issues | Word and Google Docs create messy, bloated HTML with proprietary code | Use a proper email signature generator or clean HTML code |
| Inconsistent visibility | Signature looks okay in Outlook but breaks in Gmail, Apple Mail, and others | Test in multiple email clients or avoid text editors entirely |
| Problems with images | Images often appear as attachments or fail to load automatically | Host images externally and use proper HTML img tags |
| Not mobile-friendly | Signatures don’t adapt to different screen sizes | Choose responsive design tools or generators |
💡Pro tip: Skip using text editors like Microsoft Word or Google Docs for your email signature. They might seem easy to use at first, but they can cause more problems later. For a clear, professional look, use an email signature generator or create your signature using clean HTML.
5. Hire a Freelancer or Email Signature Designer
Hiring a freelancer or a professional email signature designer is a good option when you need a highly custom and unique design that perfectly matches your brand.
This approach is worth considering if:
- You have a complex brand book with strict guidelines
- You don’t have the time or skills to create the signature yourself
- You want a completely unique design tailored specifically to your business
Pros of Hiring a Freelancer
Custom Email Signatures
A skilled freelancer can create a custom email signature that reflects your brand.
Matching Your Brand
They will design the signature to fit your brand's colors, fonts, and overall style.
Save Time
You won’t have to learn HTML or design tools. The freelancer will take care of everything, so you can focus on other tasks.
Risks of Hiring a Freelancer
- The quality of the final email signature mainly depends on the freelancer's experience and skills.
- Updating the signature can be difficult, as you often need to contact the same freelancer again, which may take time and cost more money.
- There can also be compatibility problems; the signature might not show up correctly in all email clients, especially Outlook and Gmail, if it hasn’t been tested properly.
- Managing and updating signatures for multiple team members can be complicated and time-consuming, making it hard to scale.
- Some freelancers may opt for email signature generators to create your signature. Why not take it out for a spin?
Which Email Signature Creation Method Is Best for You?
Choosing how to create an email signature depends on your needs, skills, team size, and goals. Here’s a quick guide to help you make your choice:
| Your Situation | Best Method | Why This Method is Recommended |
|---|---|---|
| Individual professional / Freelancer | Gmail/Outlook built-in or Generator | Simple, fast, and free for personal use |

Why Email Signatures Break and How to Fix Them
You've just set up your virtual business card, complete with your brand logo and contact details, and sent your first email. However, you might face various issues. Let's delve into a few common problems and how to address them.
| Issue | Cause | Fix | Prevention |
|---|---|---|---|
| Signature corrupts after forwarding | Email client converts email to plain text | Ask recipients to reply in HTML format | Use clean, simple HTML structure |
| Images don’t show up | Images embedded or not properly hosted | Host images on a reliable server and use absolute URLs | Always use externally hosted images |
| Signature looks bad on mobile | Not responsive / too wide | Use responsive design (media queries or tables) | Test on mobile devices before using |
| Signature appears as an attachment | Used as a single large image | Convert to HTML with separate elements | Never use one big image as your signature |
| Signature breaks in Outlook / Gmail | Incompatible HTML or CSS | Use inline CSS and table-based layout | Test thoroughly in all major email clients |
💡Pro tip: Always test your email signature in Gmail, Outlook, Apple Mail, and on mobile devices before sending it to clients or your whole team. This simple step can prevent most display problems.
Signature Breaks After Forwarding
This often happens when the recipient replies or forwards the email, and their email client converts the message to plain text format. As a result, your signature loses its formatting and structure.
Solution: Use clean, simple HTML code and avoid overly complex styling. There is no full guarantee, but this significantly reduces the risk.
Images Don’t Show in the Signature
This is one of the most frequent issues. Images may appear as a blank space, red “X”, or as attachments because they were embedded directly or not properly hosted.
Solution: Always host your images on a reliable external server and use absolute URLs (full link starting with https://). Avoid copying and pasting images directly into the signature.
Signature Looks Bad on Mobile
Your signature may look stretched, too small, or broken on smartphones because it wasn’t optimized for mobile screens.
Solution: Use a responsive design (table-based layout or media queries), keep the signature narrow (maximum 600px wide), and make sure text and icons are large enough to be readable and clickable on mobile devices. Always test on phones before final use.
Signature Appears as an Attachment
This usually occurs when the entire signature is created as one large image. Email clients treat it as a file rather than part of the message.
Solution: Never use a single image for your full signature. Instead, build it using HTML with separate elements (text + individually hosted images for logo, photo, and CTA).
Email Signature Best Practices
Many people very often underestimate the power of email signatures. Those signatures provide you with an opportunity to make it clear who you are, make it simpler for your customers to reach you, and give people a possibility to learn more about you, your business, and your services.
According to The State of Business Email Marketing report, 82% of marketers use email signatures to increase brand awareness and reputation.
Thus, it’s better to carefully think about the data you want to include in your email signature so that you can benefit from all the advantages an email signature provides.
Want to create a professional email signature that leaves a lasting impression? Here are a few suggestions that will help you create a professional-looking email signature.
1. Keep Only Essential Information
Focus on elements like your name, job title, department, and contact details. Consider your preferred communication channels when deciding what to include, such as phone numbers for companies relying on calls or website links for those preferring online forms.
This is also related to your social media profiles and other possible contact information. Just figure out what communication channels would fit you best and add them to your email sign-off.
2. Use a Clean and Branded Design
The professional signature should contain your business information. Some people neglect that. If you represent a company, it’s better to include your corporate email, and your title, and share your website. For personal needs - feel free to be more creative.
Simplicity becomes a synonym for competency. When it comes to your email signature, make sure you make everything about it clear and to the point so as not to confuse your addressee.
“Make every detail perfect and limit the number of details to perfect”, as Jack Dorsey says. Simple and even minimalistic approach rocks.
When designing a professional email signature, it’s all about presenting your information in a modern, stylish, and matching corporate identity way.

3. Make Links and CTAs Easy to Click
- Underline all links or use a clear color so they stand out.
- Make social media icons 24 to 32 pixels in size.
- Add enough padding around buttons and links so they are easy to tap on mobile devices.
- Use clear text for links, like “Visit Our Website” instead of just showing a URL.
- Put the most important call-to-action (CTA) near the top or in a noticeable banner.
4. Optimize for Mobile and Dark Mode
- Keep the total width under 600 pixels.
- Use a layout that adjusts to different screen sizes, either with tables or media queries.
- Select colors that stand out and are easy to read in Dark Mode.
- Make sure body text is at least 14 pixels in size.
- Check how the signature looks on both light and dark backgrounds.
5. Test Before You Install It
Send test emails to different accounts like Gmail, Outlook, and Apple Mail. Check how it looks on both desktop and mobile devices. Make sure it appears correctly in Dark Mode. Click all the links to ensure they work and confirm that images load properly. Finally, forward the email to see if the formatting stays the same.
Common Email Signature Mistakes to Avoid
To create a professional and effective email signature, avoid these common mistakes:
1. Don’t use one big image for your signature
A single large image can cause visibility problems. It makes links unclickable, does not work well on mobile devices, and increases the chance of being marked as spam.
2. Don’t overload your signature with information
Too much text, multiple phone numbers, quotes, or many links make it look messy and unprofessional.
3. Check your links
Always ensure that all links, including your website, social media, and calls to action, are working.
4. Keep banners and CTAs smaller
Large promotional images can slow down email loading times and may frustrate recipients.
5. Make sure it’s easy to read
Low contrast between text and background, especially in Dark Mode, can make your signature hard to read.
6. Update your information
An outdated job title, phone number, or company name can hurt your credibility.
7. Design for mobile
A signature that looks good on a desktop might not display well on smartphones.
8. Always test your signature
Testing it across different email clients and devices helps avoid display problems.
By avoiding these mistakes, you can create an effective email signature.
