The Ultimate Guide to Email Design In 2025


You might think that email is a dying medium, but according to a report by Campaign Monitor, their customers sent 13 billion more emails in 2020 than in 2019, over 100 billion in total. Making your emails stand out from the crowd is no easy task with all this competition.

Good email design can help you break the ice with potential readers and grab their attention right off the bat.

With the right design, you can capture your reader’s imagination, get them engaged, and push them to press “buy now” on your product or service.

If you’re not quite sure what constitutes good design — don’t worry. That’s what we’ll cover in this guide. Specifically, we’ll teach you how to improve your email designs and even show you 26 examples to inspire you.

What Makes an Email Design Good?

Over 90% of the United States population currently uses email. So, of course, there’s no one perfect style of email design that will appeal to everyone.

However, a few universal concepts can help you consistently design effective emails. We like to call them “the three Cs.”

  • Clear: the objective of the email is evident straight away
  • Captivating: the email grabs the reader’s attention and piques their interest
  • Creative: the email is unique and stands out from other marketing emails

Let’s look at an award-winning example to see what the three Cs look like in real life.

HP Instant Ink marketing email.

This marketing email from HP Instant Ink won an IAC Award for “Best Technology Email Message Campaign” in 2021.

The logo for Instant Ink and the headline emphasize the idea of ink shipped to your home.

It’s captivating — with a mix of illustrations, colors, and a great featured image, it grabs your attention.

It’s creative — not focusing on the ink cartridges, but the fact that the service delivers to your doorstep.

You don’t need the most amazing idea of all time to create a good design. Start by evaluating your existing emails and finding things to improve.

You should consider:

  • How your emails stack up against the three “C’s”
  • Your Click-Through Rate (CTR). For reference, the average CTR ranges from 2.6% to 2.34%
  • Whether your emails help you meet your goals
  • Whether your emails drive traffic to your website

When creating new emails and campaigns, keep building on what you’ve learned.
