What is an email signature or email footer?

An email signature often called an email footer, is a part of a brand image, which is more than just your company name and title. It provides a recipient with information about your business and helps recognize it, among others.

Should you treat your email signature as a business card?

We usually exchange business cards while networking at offline events. The cards help us create a more personal and memorable impression and build a foundation for future relationships. So why not do the same when we interact with people online? Moreover, the email signature, which we add at the bottom of every email message we send, belongs to the most affordable marketing tactics that can raise awareness, increase reach, and build trust. In fact, our research shows that 33.1% of people find email signatures to be a key factor in building trust with a sender.

Email signature design best practices

Before you create the best email footer and make your emails stand out, think about what it conveys to people about your company? Does it look good enough to represent your awesome brand? Did you polish its design so carefully that recipients can say they deal with a pro? Whether you’re a large or small business, be sure to treat your email signature with as much care as you would for any other email marketing strategy. With that in mind, we want to share some email signature best practices for 2023.

1. Keep your email signature design minimalistic

When it comes to email signature design, remember that less is more. Keep your sig clean, neat, and simple. Take into account your corporate colors and fonts while making an email footer.

  • Stick to two or three colors in your signature palette.

If you use more than that, you risk distracting the reader.

  • Choose one email signature font. Don't use too many fancy fonts.

Instead, go for something clean, elegant, and simple. If your organization has a particular font style for marketing materials, consider using it in your email footer to keep everything consistent.

2. Use visual gradation to highlight important information

To highlight the essential parts of your email footer, make sure you do the following:

  • Prioritize your information

Do you know what a visual hierarchy pyramid is? Creating a visual hierarchy is important for directing readers’ attention. It is the process of organizing and prioritizing content or images so that it gradually draws attention to the most important part of the piece of content and makes it easy to read information. The visual hierarchy is like a pyramid — with the most important elements at the top (conveyed in larger fonts). The information is gradually aligned by its importance as you go down. For example, you can use the following formula for email signatures: name > title > address > phone number > email > website > social media accounts. By presenting your contact details this way, you ensure that the recipient naturally processes the most important information first.

  • Use bold

Use bold letters on the most important things wisely as they draw the reader’s eyes quickly.

  • Use font size

If you need to draw attention to a specific aspect of your email footer, like your name or awards/certificates, play around with font size. However, bear in mind that the font size should be anywhere between 10 and 12 to ensure the best readability.

  • Use space dividers

Use space dividers if necessary to separate different elements of your sig and direct the recipient’s eye.

3. Use high-quality images and graphic elements

When using visuals in your email footer, it is always a wise idea to follow these simple rules:

  • Use photos with a neutral background;
  • Choose a headshot instead of a full-body photo;
  • Use graphics with proper resolution and clean & simple design.

4. Add only relevant and professional social icons

Our recent study showed that 80% of those who use professional email signatures in their business communications include social links in their sign-offs. Tailor your email footer according to your target audience and the brand. Use a maximum of four social media icons to keep the space uncluttered. Also, be sure to choose a set of professional-looking social media buttons that matches the rest of your email signature.

Things to avoid in your email signature design

When it comes to working on email signature design, you must be mindful of what not to do. Here is a checklist of the five most common email signature mistakes that you should avoid.

  • Overloading your signature with text information

Too much text can ruin the nice appearance of your email signature. It is best not to make each line of the sig more than 72 characters.

  • Using too much color

Just like images, colors are great for drawing recipients' attention and conveying emotions. However, if you use too much of them, you risk looking childish and unprofessional.

  • Using too many and not web-safe fonts

Playing with many different fonts in your email signature is a big no-no. It is just distracting, hard to read, and makes you look unprofessional. Speaking about web-safe fonts, if you use some typeface that most people don't have installed on their computers or smartphones, your signature will look pretty messed up for most of them.

  • Adding too many social icons

Your email footer will look cluttered if you add icons for all of your social media channels. As we already mentioned, it is recommended to use no more than four social media buttons.

  • Not uploading images for Retina screens

Many of your recipients might read their emails on Retina displays. To avoid them seeing blurry images on your email sig, remove blur from photos and be sure to upload high-quality pictures for Retina screens.

Email signature marketing best practices

As we have clarified already, we can use an email signature to provide recipients with information about who we are and what we do. But we can also take this practice to the next level by making the signature reflect the marketing campaigns we run. How? Read this email signature marketing guide.

So, what shall we begin with?

1. Add calls to action to your email signature

When you check out good business email signature examples, you will notice that most of them, as a rule, have clear, simple, not too pushy calls to action (CTAs). You can experiment with adding various types of CTAs to your email footer. The calls to action range from offers to subscribe to your YouTube channel to links that send recipients to your recent blog post. To find out more about CTAs and how to use them in your email signature efficiently, check this guide.

  • Add a link to your calendar

By doing so, you will help your co-workers, partners, and customers grab time on your calendar without the need to set up a meeting by email or phone.

  • Ask for review

Add links to your review sites, and your customers will see them every time they talk to you via email.

  • Add a link to download reports/case studies

When you talk to potential clients, it's always wise to share reports, case studies, and success stories.

  • Links to your marketplace

An email signature can also serve as an excellent way to market your business through email. And if you sell something on Amazon, eBay, Etsy why not mention this in your sig?

  • Subscribe to your channel

Encourage your email recipients to subscribe to your channel on social media by adding a CTA right in your email signature.

2. Email signature as a tool to increase your brand awareness

If you are looking for ways to promote greater brand awareness for your organization, consider adding some info about awards, certificates, positive customer feedback in your email signature.

  • Awards and certificates

If your company has ever received any certificates or awards, a perfect place to show them off is the bottom of every email message you send to partners, clients, and prospects.

  • Announcements

Your email footer is also a great place for making time-sensitive announcements like trade show appearances, special holiday hours, the launch of new products or services.

  • Customer reviews

Would you like to display customer satisfaction ratings and reviews in your emails too? Put links to customer reviews into your email signature and get them noticed.

3. Run email signature banner campaigns to increase conversions

Generate traffic to your website by linking it to banner ads. You can see them on blogs, news portals, social media, and even email. Promotional banners can help you show stories, moments, upcoming events, special offers, and bring out a reaction.

Below are some occasions and marketing materials you can promote through the email signature banners:

  • Recent blog post
  • Upcoming webinar
  • Special offers
  • Free access to your tools
  • Invite people to meet at the conference
  • Discounts
  • Listen to your podcast

Be sure not to overwhelm users with too many calls to action. If you offer people too many choices, they may not choose anything at all.

Email signature management best practices

As we have already established, an email signature is your digital business card. And it is a way to connect with your existing and potential customers. Despite that, many businesses fail to make email footers a natural part of its branding strategy and ensure all signatures are consistent and updated across the entire organization. So, don’t miss the opportunity to turn your employees into your brand ambassadors and create company email signatures following these simple rules:

1. Create a standardized email signature template

When it comes to creating employees' email signatures, it's important to keep them uniform and consistent.

  • Use a logo

An email footer with a company's logo will increase your brand awareness. Every time the reader sees your employee's email signature, they will associate it with your brand, thus strengthening your brand recognition.

  • Stick to your brand colors

It is recommended to use a color palette that is consistent with your brand colors. But let us remind you once again: it isn’t a good idea to use more than two colors.

  • Standardized contact information

A standard corporate email signature should contain the name and title of the employee sending the email, as well as their contact data. But bear in mind that you may need to personalize company signatures according to the employees’ position, department, and scope of their email recipients. For example, sales team email footers should include extended company details compared to signatures of IT staff members.

2. Use simplified signatures for internal communication

When sending emails to your co-workers, you don’t necessarily need as much information in your footer as you would for external contacts. It should be a more compact version as you don’t need to include details such as a legal disclaimer, marketing banners, or social media buttons. Including a logo, name, job title, telephone extension, or direct dial would be enough.              

3. Use simplified signatures for replies and forwards

Consider simplifying your email footer for replies and forwards. It will help you avoid overloading your conversation threads.

4. Add different CTAs and banners for different departments

Make specific email footers for different departments within your company. For instance, your salespeople's signatures can contain a banner with a "Schedule a demo" button.. And signatures for your marketing department can promote recent content and increase sign-ups.

5. Share a link to the predefined signature template in your email signature generator

Find a service that will allow you to centrally manage and deploy corporate signatures for any scope of mailboxes in your organization.

Technical aspects you should pay attention to

There are many technical aspects to pay attention to when making your email footer beautiful but responsive.

1. Make your signature mobile-friendly

We all use smartphones these days, and the number of people checking emails on their phones is ever-increasing. Did you know that 55% of the total electronic messages delivered every day are opened on mobile devices? That’s something to take note of. When working on your sig, think about what recipients will see on their phones. Pay attention that the screen of a smartphone is much smaller than a PC's screen. It means that the objects you use in your email signature must be larger, while the number of them smaller. Also, bear in mind that the speed of the mobile Internet can be limited, especially if the user did not bother clearing the cache or updating the device.

2. Run a compatibility test

There is a common misconception that your email footer will be displayed correctly across all email clients. The sad truth is that it won’t.  Just because your signature looks perfect in Gmail doesn’t mean it will look the same in Outlook. To ensure it looks good in different email clients, you need to run a compatibility test between all of the most popular email clients.

Here is an example of how this test should be performed:

  • Sending from Outlook 2016 to Gmail
  • Sending from Outlook 2019 to Gmail
  • Sending from Gmail to Outlook 2016
  • Sending from Gmail to Outlook 2019
  • and so on.

Hopefully, various tools make it convenient and easy to ensure your email signature is displayed correctly across all the platforms. Our next chapter is focused on that topic. Keep reading.

3. Remember about email signature size

With email footers, there are two sizes to check. The size in pixels and the size in kilobytes. For desktops, the recommended maximum email signature size is 700px (width) x 300px (height). It is best to keep your sig 320px (width) x 600px (height) for mobile devices with smaller screens and scaling. Also, try to keep your email footer under 50KB.

4. Image hosting

If you host images on an untrusted domain, your emails might not be delivered to the recipient's inbox. That is why it is essential to use a reputable commercial host for any images you include. Some of them are your server, Google Photos, Amazon S3.

5. Make sure not to use double tracking in signatures

If you choose to track impressions and clicks on the links in your signature, be sure not to use other email tracking services/extensions (e.g., Mailtrack). Otherwise, you risk being caught by spam filters.
