\u00a0<\/h2>\n
But this is not always the case. There are several reasons why, sometimes, what you design is not what you end up with.<\/p>\n
It is natural for you to want your messages to display flawlessly in your contacts' inbox, just as you viewed them during their creation.<\/p>\n
<\/strong><\/h2>\n
\u00a0<\/p>\n
However, this may not be the case and one of the most frequent reasons is the use of a single image as the basis of the message.<\/p>\n
It may seem very attractive to design email marketing pieces based exclusively on a large image, as if it were a print ad. But this type of approach ignores fundamental characteristics of the channel, and often leads to significant display, interaction and performance problems.<\/p>\n
When the message is composed of a single image, the risks increase considerably. The content may not be displayed, losing all effectiveness. And if the recipient sees nothing, he or she will simply discard the message.<\/p>\n
\n
Some email readers block images<\/strong><\/li>\n<\/ol>\n
Do you really want your readers to have to take an extra step to see your message?<\/p>\n
\n\n
\n
\u00a0The image will look like this:\u00a0 \u00a0 \u00a0\u00a0 \u00a0 \u00a0\u00a0<\/strong><\/td>\n
\u00a0And what you sent is this:<\/strong><\/td>\n<\/tr>\n
\n
\u00a0<\/td>\n
\u00a0<\/td>\n<\/tr>\n
\n
\u00a0<\/td>\n
\u00a0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Many email clients block the automatic display of images by default. If you send a message composed only of an image, a blank space will be displayed.<\/p>\n
This creates a frustrating experience: the reader doesn't see the content, doesn't understand what the message is about and has no incentive to unblock anything. They will most likely ignore the message, unsubscribe or even mark it as spam.<\/p>\n
If you decide to use images in your mailings, always make sure to accompany them with real text and well-coded HTML structures. This way, the content will be understandable even if the images are not displayed.<\/p>\n
\n
It is a format associated with spam<\/strong><\/li>\n<\/ol>\n
Image-only messages are a tactic historically used by spammers, as by avoiding text, they attempt to evade malicious content detection filters.<\/p>\n
For this reason, many anti-spam filters consider this type of formatting suspicious and block the message. Even if you have followed best practices, if your message is perceived as spam because of its structure, it will never reach those who need it.<\/p>\n
This can negatively affect your sending reputation and decrease the actual delivery rate of your campaigns.<\/p>\n
\n
Do not allow to offer alternative views of the content<\/strong><\/li>\n<\/ol>\n
A good practice in email marketing is to offer a backup version of the message, either in text format or via a link for viewing in the browser.<\/p>\n
A message containing only an image cannot provide this alternative if the image does not load. There will be no header, preheader text, or indication to view the content otherwise.<\/p>\n
This affects both the user experience and your ability to connect with them. A message without visible content is a message lost.<\/p>\n
\n
Cannot be found by the addressee<\/strong><\/li>\n<\/ol>\n
Imagine that one of your contacts wants to search for a message from you to check it again.<\/p>\n
If your mailing is based only on an image, it will not be indexed by the internal search engines of the email platforms. In other words, it will not be found or filtered by keywords, which reduces the usefulness of your messages over time.<\/p>\n
Real text allows your campaigns to continue to generate value even weeks after they have been sent.<\/p>\n
\n
Images may take some time to load<\/strong><\/li>\n<\/ol>\n
Loading speed remains a key factor. An image that is too heavy may take a long time to open, especially if the user is using a mobile network or an unstable connection.<\/p>\n
Every second of waiting increases the probability of abandonment. When content does not appear immediately, the reader simply moves on to the next message.<\/p>\n
In addition, large messages consume more mobile data and may be perceived as an unnecessary burden by the user.<\/p>\n
\n
They are incompatible with accessibility and machine readability<\/strong><\/li>\n<\/ol>\n
Visually impaired users, who use screen readers, will not be able to interpret the content of an image if there is no alternative text or clear semantic structure.<\/p>\n
This limits access and can also lead to non-compliance with accessibility regulations.<\/p>\n
Messages built with structured HTML and real text allow any user, regardless of device or condition, to access and understand the content.<\/p>\n
\n
Limits analysis and customization capabilities<\/strong><\/li>\n<\/ol>\n
A campaign based only on an image limits the metrics available to evaluate its effectiveness. You cannot analyze behaviors such as reading time, most viewed sections, or perform A\/B testing with text variations.<\/p>\n
In addition, you lose the ability to insert dynamic personalization within the message. Plain text, on the other hand, allows you to personalize names, interests and behaviors, which improves open and conversion rates.<\/p>\n
Practical recommendation: balance between text and image<\/strong><\/p>\n
A recommended ratio for effective and balanced messages is approximately 60% text and 40% image. This combination ensures a correct visualization, even if the images are blocked. In addition, it allows to deliver the message clearly, motivate the reader and facilitate action.<\/p>\n
If the text is well crafted and relevant to the recipient, they are more likely to want to view the entire message, even if they manually unlock the images.<\/p>\n
