Why 1 big image isn’t a good idea in email marketing

Images play a vital role in email marketing. They can capture attention, convey messages quickly, and make your email stand out in a crowded inbox. However, using one large image as the main content of your email may not be the best approach. While it may seem visually appealing at first glance, this strategy can lead to several problems that affect both user experience and email performance. Here’s why relying on a single large image isn’t always a good idea in email marketing.


1. Slow load times

One of the biggest downsides of using a large image in an email is that it can significantly slow down load times. Email recipients expect fast, seamless experiences, and if your email is slow to load due to large image files, it can lead to frustration.

Why it matters:

  • Mobile optimization: Many users check their email on mobile devices, which may not always have the fastest data connections. Large images can take longer to download, causing delays and a poor user experience.
  • Increased bounce rates: Slow-loading emails can cause recipients to abandon the email before it fully loads, affecting your open rates and engagement.

What to do instead:

  • Compress your images to reduce file size without compromising quality.
  • Use responsive design so that images load correctly and fit different screen sizes.
  • Keep your total email file size under 1MB to improve loading times.

2. Image blocking

Many email clients block images by default, especially if the sender is not recognized. This means that when recipients open your email, they might not see the large image you’ve included, and it could affect the message you’re trying to convey.

Why it matters:

  • Missing context: If your email relies heavily on a single image to communicate key information, it may not be effective when that image is blocked.
  • User frustration: If the image doesn’t load and there’s little to no text to explain the content, recipients may quickly lose interest and mark your email as spam.

What to do instead:

  • Always include ALT text for every image. This will describe the image’s content if the email client blocks it.
  • Include enough text in the email to convey the message even without the image.
  • Ensure that critical information is accessible in both image and text formats.

3. Poor user experience

Emails with one large image can be difficult to navigate, especially on mobile devices. While large images may look good on a desktop screen, they can disrupt the flow of content and make it harder for users to read and engage with the email.

Why it matters:

  • Mobile readability: On smaller screens, large images often require scrolling, which can be frustrating for users who want to quickly access the main content of your email.
  • Cluttered design: One big image may overshadow important text or calls-to-action (CTAs), leading to a less effective email design.

What to do instead:

  • Use multi-column layouts or smaller images that are easier to view and interact with on mobile devices.
  • Break your content into sections with clear headings, so readers can easily scan and understand the message.
  • Place CTAs in prominent spots that don’t get hidden behind large images.

4. High risk of being flagged as spam

Emails that rely on a single large image with little or no text may trigger spam filters. Spam filters look for certain patterns, and emails that contain only one image with no accompanying text can resemble phishing attempts, which often use images to bypass filters.

Why it matters:

  • Deliverability issues: If your email looks like spam to email filters, it may end up in the spam folder, reducing your email’s visibility and engagement.
  • Lack of trust signals: Spam filters can flag emails with images but little text, as they tend to lack the proper context or credibility.

What to do instead:

  • Maintain a healthy balance between text and images. Aim for a text-to-image ratio of at least 60:40.
  • Use clear and relevant text alongside images to explain the purpose of your email and make it more trustworthy.
  • Include a recognizable sender name and ensure your subject line is clear and relevant to the content.

5. Reduced accessibility

Large images can also be a barrier for people with disabilities, especially those using screen readers. When email content is presented primarily through images, screen readers can struggle to convey the message effectively, making your email less accessible.

Why it matters:

  • Limited reach: If your email doesn’t include enough descriptive text, it can alienate people with visual impairments who rely on screen readers to access content.
  • Legal considerations: Accessibility is becoming more important, and not considering this aspect could potentially lead to legal issues, especially in certain industries.

What to do instead:

  • Use ALT text to describe all images for visually impaired readers.
  • Ensure your emails are compatible with screen readers by keeping text-based content at the forefront.
  • Follow best practices for email accessibility, like maintaining a readable font size and clear contrast.

6. Missed opportunities for Engagement

Emails that rely solely on one big image miss the chance to provide additional information that could engage your audience. By including text, links, and multiple images, you can encourage users to interact with your email in various ways—whether it’s clicking on a link, watching a video, or learning more about a product.

Why it matters:

  • Limited engagement: A single image doesn’t offer as many opportunities for interaction as a more dynamic email that includes links, buttons, and other interactive elements.
  • Increased bounce rates: Without a variety of content, recipients are less likely to spend time reading the email or taking action.

What to do instead:

  • Include a clear call-to-action (CTA) that encourages recipients to click through to your website or landing page.
  • Use diverse content like text, multiple images, and videos to create a more engaging and informative experience.
  • Include social media buttons to encourage sharing and further interaction.

Conclusion

While a single large image might seem like a great way to grab attention, it can lead to a range of issues, from slow load times and image blocking to poor user experience and deliverability problems. Instead of relying on one big image, use a well-balanced mix of text and images, optimize your content for mobile, and ensure your email is accessible to all users. By following these best practices, you can improve engagement, enhance your email’s performance, and create a more effective email marketing campaign.
