Best Colors To Use In Email Marketing

The best colors to use in email marketing are those that evoke a positive emotional response from the reader, and encourage them to click your call-to-action button. Keep your color scheme contrasting to make sure your text is easy to read …

Email marketers often question the value of email. After all, it’s a medium that many don’t read to completion. The most opened emails are those that look visually appealing. If you want to get more action from your subscribers, then use these best colors in email marketing.

When to use which color

Every color has both personal-level and public-level significance. Personally, a color can be associated with a person’s memories and nurturing, which is tough to predict. Many personal-level interpretations often contribute towards forming a popular—or public—perception. This is prominently seen in the use of colors in advertisements, movies, and images worldwide.

The public level of preferences can be categorized into groups:

  • Global significance
  • Psychological significance
  • Cultural significance
  • Seasonal significance

Global significance

The global reach of a color often creates universal narratives. Some colors become synonymous with certain kinds of messages—for example, black and white are often associated with emails on fashion accessories and apparel.

Psychological significance

Certain colors can excite, scare, or anger people. If you use particular colors in the correct combination, you can subtly initiate interaction from contacts. Understanding which colors have what effect is important, because you don’t want to accidentally use colors with a negative psychological impact when you want a positive response from people.

Cultural significance

Many colors are associated with festivals, customs, and practices. One color can have a variety of significance around the globe. Red is considered auspicious for many South Asian countries, while it’s widely used to denote Christmas in the West.

Seasonal significance

For ages, colors have depicted different seasonal aspects—orange was synonymous with autumn, green was with spring and so on. As an email marketer, you can replicate these trends in your email campaigns and give yourself a shortcut to invoking a feeling in a reader.

Now let’s look at some major colors and examine their different types of significance.

Applying color to email marketing

What captures the reader’s attention once they open an email is not the text, but the visual elements, such as color, design, and images… However, it is color in particular that can awaken interest, or, conversely, cut it at the root, if the combination of colors does not work well.

To help you with your email marketing strategy and to ensure you use the ideal color combination to achieve your goals, we have prepared this infographic with examples of real emails and the messages that each color transmits to the user.

Psychology Of Colors For Email Marketing

In a Huffington Post article, Leslie Harrington, Executive Director of The Color Association of The United States suggests that: “we react on multiple levels of association with colors. There are social or cultural levels as well as personal relationships with particular colors”. You also have an innate reaction to color. For example, when you look at red, it does increase your heart rate. It is a stimulating color. This goes back to caveman days of fire and danger and alarm.”

Keep your product in mind when picking colors for your marketing campaigns

When considering the use of certain colors in email campaigns, the first thing we need to consider is its association to our brand. Maintaining the integrity of the brand is our number one goal, and after that we can start to think about the messaging and the moods that the colors will portray to the audience.

In a research report entitled ‘Impact of Color in Marketing’, it was uncovered that 90% of decisions made about certain products can be based on their color alone.

Gender plays a role when picking colors

Another angle on choosing the right color for your email campaigns is gender. Psychology of colors can be gender specific and certain colors are favoured more than others by males and females, as KISSmetrics uncovered.

After considering your target audience, you’ll want to think about conversion. What colors will invite your prospects to take action? We recommend A/B testing (or A/X testing!) as well as Segmentation as different approaches work differently for each campaign and segment.

Here is an experiment done by Hubspot:

call to action colours in email

Taking into consideration what we have learnt so far about these two colors, as well as putting them in a modern context such as driving, where green means “Go”, red means “Stop”; which of these two buttons do you think had the higher conversion

The red button outperformed green by 21%! Probably not what you had in mind, right? Knowing which colors to use for call-to-actions is an ancient old and biblical discussion that will never end (okay, not really).

The lesson we must learn here is that even if we do our due diligence and research, we should always be testing our campaigns. Every customer is different and their response to each color can vary depending on a variety of reasons such as mood, location, device used, choice of color combination and so much more.

Impact of the use of color on email marketing deliverability

As you may already know, there are a host of key phrases which Internet Service Providers (ISPs) don’t like, which means if these words are used then the email is very likely to go straight to the spam folder. These are called SPAM triggering phrases.

Just like these phrases which may send your email into SPAM, you’ll need to consider your image to text ratio – as a rule of thumb use 25% image and 75% text.

Unfortunately, ISPs don’t reveal exactly what triggers spam filters, however through the same collaborative effort of finding out what words trigger them and what text to image ratio we should be using, we have come to understand that extensive use of red in texts is one of the main tip offs.

Red is known as a ‘loud color’, so extensive use of it within text or background usually means that we’re really trying to get the users attention. The same principle is used towards CAPITALS, large texts and symbols such as exclamation or the dollar sign.

Most SPAM filters work on a scoring system. Each of the mentioned attributes above carries a maximum score. The higher your total score, the more likely your emails will end up in SPAM.


We spend a lot of time making sure the body of our sales letters are perfect – because, that’s what sells the product. The color selection for your sales letter is important. It sets the tone for the message you’re about to send.
