Email UI/UX guide to increase your open rate
User experience and user interface design are essential. to increase the click-through rate in your email marketing campaigns. In this guide we review the key UI/UX aspects to achieve this goal.
Hierarchy of Information
a) Texts: headlines, bodycopy…
- - Use clear and eye-catching headlines to grab attention. Headlines should highlight the main message.
- The body copy should be legible and structured in short paragraphs.
- - The user does not read the email, but scans it, so the texts should be visually establish the importance of the messagesby means of text size, bold, colours...
- - Maintain a high contrast between text and background to ensure legibility.
- - Use line breaks and short paragraphs.
- - Avoid extravagant alignments (vertical text, diagonal...).
(b) Guíto reading
- - Design the user's journey through the email, guiding them towards calls to action.
- - Use bullets and lists to present information in a concise and easy-to-scan manner.

Contrasting colours
- - Use background and text colours that provide clear contrast to improve readability.
- - Use a striking colour and in contrast to the surroundings for calls to action.
- - Using too many colours can disperse the attention and therefore the click.
Highlights
- - Highlight important elements such as links and calls to action (CTAs) by using eye-catching colours, larger or bold elements.
- - But beware of overdoing it: if everything is highlighted, nothing is really highlighted.
- - Use animations sparingly. Too much movement can be counterproductive. Opt for subtle, localised animations to draw the user's attention to an element.
ReduccióCTAs
- - Limit the number of CTAs in an email, the diversity of options disperses the action.
Weight and load of images
- - Optimise the weight of your emails so that they load quickly. Heavy images (+200k) can take several seconds to load and we can lose the user in that short time.
Text vs. Image
- - Use text instead of images for crucial information, such as CTAs. Email clients do not always automatically load images, and text is more accessible.
- - If you use images, be sure to include alternative text so that recipients know what the image is about even if it doesn't load.
Brand consistency
- - Maintain brand consistency in your emails. Use the same colours, fonts and styles that represent your brand in other channels.
- - Use your company logo and make sure it is linked to your website or landing page.
