Email signature banners help you direct email recipients to content, product pages, and offers. Here's how you can maximise their impact.


3.9 billion.

That’s the estimated number of people that used email every single day in 2020. But the amount of people using email to its full potential are few and far between. Why?

Because they don’t know about the marketing value one thing could bring: 

Email signature banners.

With banners,  you’ll grab recipients’ attention from the moment your email comes into their inbox. That means you have the chance to generate more traffic, more conversions, and more revenue on your site. 

All you need to do is use colour, eye-catching visuals, and CTAs to make every email you send more meaningful to your business. 

In this guide, we’ll tell you everything you need to know about email signature banners.

What are email signature banners? 🤔

Email signature banners are usually placed at the bottom of your email signature, underneath where you sign off.

Banners serve the purpose of advertising either yourself or a company, meaning you can promote new content, drive signups to events, and advertise special offers.


What are the benefits of email signature banners? 🤔

So, you might be asking yourself these questions:

  • What’s the point in an email signature banner? 
  • Can’t I just advertise my content in the actual email? 

We get it. It’s probably not the first thing that comes to your mind when you think about email signatures. 

But banners allow you to stand out in crowded inboxes and target prospects where you have their undivided attention... 

This is because: 

→ Emails are sent in a high volume. Relevant email signature banners can frequently convert customers. 

→ Emails can also be targeted by different departments within a business. Relevant email signature banners are sent out to the specific contact list. You’ll increase your chances of nurturing and converting your customers. 

→ Emails are also cost-effective. Banners are a form of email signature marketing that you own. There’s no hidden fees.

Here’s some other reasons why you need a banner. 

You'll stand out from the crowd 💁

The average working professional receives over 200 emails every day. But, they only reply to 25% of them. 

So, what could be the reason for your email ending up in the dreaded 25% pile? 

It could be a poor subject line. It could be a poor hook. It could be that the email is a plain, boring block of text. 

In the case of the latter, a striking email signature banner will help ensure that you’re top of mind when a prospect makes a buying decision. 

It's a great marketing tool ⬇️

Aside from differentiating your emails in your recipients’ inboxes, email signature banners are a marketer’s dream. With them, you can: 

Direct traffic to your company website 🚦

You can use an email signature banner to divert recipients’ attention to your company website. 

Banners are a visual feature, so you can design it around brand colours. 

The result? 

Strengthened brand awareness. This is because recipients will be reminded about your company every time they get an email from you. 

Promote new content 👇

If you’ve recently written a new eBook or white paper, then a banner can help you promote it. Try using a CTA like: “download your copy” to capture leads and fill up your sales pipeline. 

Strong call-to-action to add to your email signature banners

Advertise special offers 🗣️

Email signature banners allow you to promote limited-time-only deals to prospects and customers.

On Black Friday, for example, you could highlight a discount code like “BLACK40” in your banner.

Tip: You can also use banners for upselling products to existing customers. New product ranges and updated features tend to be most effective.

What are the best practices for email signature banners? 🔝

It's great you've decided to include a banner in your email signature. But before you get started, read our guidance, so you make the most of it. 

Keep the design template simple ✏️

Your banner isn’t going to be effective if it’s an eyesore. 

A good rule to follow: less is more 👇

A note on colour 🎨

Banners are usually one single block of colour. But if you do want to use more than 1 we’d recommend no more than 2 so as not to overwhelm or distract the recipient. 

You can do a colour split, which is useful if you’ve got more than one company colour to play with. 

A note on font 🔤

The same goes for the font you use for the copy on your banner. Stick to one font, and make sure it’s legible. 

It’s a waste of time if recipients can’t read the banner. 

Remember: every part of the email signature needs to serve a purpose. 

Make sure recipients immediately know what they can gain by clicking on the banner. 

Don't make the banner misleading 😕

You need to make sure your banner matches the content you're linking in order to make the user journey as easy as possible. 

For example, if your banner is promoting a specific eBook, don’t direct a recipient to your Resources page.
