In the world of email marketing<\/strong>, the visual aspect is crucial for capturing the attention of your subscribers. However, there is a common practice that many brands still employ (just take a look at your Promotions tab to see it’s true) which, far from improving results, can seriously harm them: sending emails composed solely of images<\/strong>.<\/p>\n\n

Although the temptation to use only images for aesthetic reasons is very strong, emails with images only<\/strong> present several problems that negatively affect the deliverability, accessibility, and effectiveness of your campaigns. In this article, we explain the most common mistakes<\/strong> of emails composed solely of images and why this practice doesn’t work, and what alternatives<\/strong> you can apply to improve your results<\/strong>.<\/p>\n\n\n\n

What are emails composed solely of images?<\/strong><\/h2>\n\n

We refer to emails with images only<\/strong> as those emails where all the content<\/strong> (text, buttons, links, calls to action…) is completely embedded within one or more images<\/strong>. That is, all the content visible to the user is in graphic format, not in plain text or HTML.<\/p>\n\n

This technique is mainly used for design reasons: it allows greater visual control of the layout, fonts, and styles, especially when aiming to be 100% faithful to a brand’s branding. However, this apparent advantage brings with it a series of technical and functional drawbacks.<\/strong><\/p>\n\n

Why don’t emails with images only work?<\/strong><\/h2>\n\n

Low deliverability<\/strong><\/h3>\n\n

The spam filters<\/strong> of many email providers (Gmail, Outlook, Yahoo, etc.) consider emails with little or no readable text<\/strong> as suspicious<\/strong>. This is because spammers often hide content in images to avoid detection<\/strong>.<\/p>\n\n

Therefore, emails composed only of images have a much higher likelihood<\/strong> of being marked as spam<\/strong>. As a result, your emails may end up in the spam or promotions folder,<\/strong> significantly reducing your deliverability rate<\/strong>.<\/p>\n\n

\ud83d\udc49 Tip<\/em>: to avoid compromising deliverability, seek a good balance between image and text<\/strong>. A good starting point would be 60% text<\/strong> (remember to reach at least about 400 characters) and 40% image<\/strong>.<\/p>\n\n

Accessibility issues<\/strong><\/h3>\n\n

If you don’t include real text in your email, you create accessibility issues. An email with images only cannot be interpreted by screen readers<\/strong>, making them rely on alternative text (ALT)<\/strong> to understand the visual content. And let’s be honest, what percentage of people fill in the alternative text? As a result, visually impaired people will not be able to access your content<\/strong>. This not only limits your reach<\/strong> but also goes against good digital accessibility practices and can harm your brand image.<\/p>\n\n

Additionally, if a user needs to translate<\/strong> the email content, the text within the images cannot be automatically translated<\/strong>. This reduces your global reach and message comprehension.<\/p>\n\n

\ud83d\udc49 Tip<\/em>: Avoid placing important texts or buttons within images. Screen readers won’t detect them, which can exclude a significant part of your audience.<\/p>\n\n

Automatic image blocking<\/strong><\/h3>\n\n

Some email clients block<\/strong> images<\/strong> by default<\/strong> (especially if the sender is not in the recipient’s contact list) and allow users to customize<\/strong> this setting, as for privacy and security<\/strong> reasons, many users choose to block images due to the presence of tracking pixels embedded in them.<\/p>\n\n

Imagine the impact: you send an important promotion, but the user can’t see anything<\/strong> because the images don’t load.<\/p>\n\n

Therefore, you must always keep in mind that your images might not display<\/strong>. Remember to design your emails so they remain understandable and functional even when images are turned off.<\/p>\n\n

\ud83d\udc49Tip<\/em>: You can also remind your subscribers to enable image viewing<\/strong> or add you to their safe sender list<\/strong> to enjoy the full experience.<\/p>\n\n

Slow loading times<\/strong><\/h3>\n\n

Images usually have a much larger size<\/strong> than plain text. If not optimized correctly, they can slow down the email loading<\/strong>, especially on slow connections or mobile devices. This directly affects the user experience and can increase the bounce rate<\/strong>, with many users deleting the email without waiting<\/strong>.<\/p>\n\n

\ud83d\udc49 Tip<\/em>: ensure your images are optimized for mobile and compressed<\/strong> (here’s a post<\/a> to learn how to do it). Add more content in plain text<\/strong> to balance the visual weight of the email and ensure a good experience.<\/p>\n\n

Non-responsive design<\/strong><\/h3>\n\n

A single image with all embedded content does not adapt correctly to all screen sizes<\/strong>. On mobile devices, it’s common for the text to appear small, making it difficult to read and reducing the message’s effectiveness. This can lead to:<\/p>\n\n
