Frequently Asked Questions

Retina Displays & Email Image Quality

What are retina displays and how do they affect email image quality?

Retina displays, introduced by Apple in 2010, use twice as many pixels as standard displays to make graphics crisper. However, if images are not designed for these higher pixel densities, they can appear blurry or pixelated in emails viewed on retina devices. This can make marketing materials look unprofessional and reduce their effectiveness.

Why do images look blurry on retina displays?

Images look blurry on retina displays because these screens have a higher pixel density than standard displays. If an image is created at a standard resolution, it does not have enough pixels to display sharply on a retina screen, resulting in a blurry or pixelated appearance.

How many people use retina displays in the United States?

As of 2021, more than 113 million Americans (47% of all smartphone users) owned an iPhone, and in 2017, there were about 100 million active Macintosh users. With 40% of these users recently upgrading to new devices, at least 85.2 million Americans regularly view emails and websites on a retina display. (Sources: Statista, The Verge, SellCell)

Why should marketers care about optimizing images for retina displays?

With at least 85.2 million Americans using retina displays, failing to optimize images can result in blurry, unprofessional-looking emails for a significant portion of your audience. Optimizing for retina displays ensures your marketing materials look crisp and high-quality, improving brand perception and engagement rates.

What types of images are most affected by retina displays?

Images with high-contrast elements, text, or geometric shapes are most noticeably affected by retina displays. These images can appear especially blurry if not optimized, while many photos without these elements may not show as much difference.

Optimizing Email Images for Retina Displays

How can I optimize email images for retina displays?

To optimize email images for retina displays, create your images at double the standard pixel dimensions. For example, if your email banner is normally 600x200 pixels, create it at 1200x400 pixels. Then, set the width and height in your HTML <img> tag to the standard size (600x200). This ensures the image appears crisp on retina screens without disrupting your email layout.

Does increasing image pixel count affect email load times?

Yes, increasing the pixel count of an image usually increases its file size, which can slow down email load times. To address this, use a file compression tool to reduce the file size while maintaining image quality. Tools like Squoosh (by Google) or Website Planet's Image Compressor are recommended for this purpose.

What is the recommended width for email banners on retina displays?

The standard email banner width is 600 pixels, but for retina displays, you should create your banner at 1200 pixels wide. Then, set the display width in your email template to 600 pixels to ensure crisp rendering on high-density screens.

Which images in my email should I prioritize for retina optimization?

Prioritize optimizing unique elements such as your logo, icons, and branded fonts. These are the most noticeable when displayed at low resolution. While optimizing all images can be beneficial, focusing on these key elements provides the best results for the least effort.

What file compression tools are recommended for email images?

Recommended file compression tools include Squoosh (by Google) and Website Planet's Image Compressor. These tools help reduce image file size while retaining as much quality as possible, ensuring fast email load times and crisp visuals. (Sources: HubSpot, Website Planet)

How do I set image dimensions in HTML for retina display optimization?

After creating a high-resolution image (e.g., 1200x400 pixels), set the width and height attributes in your HTML <img> tag to the standard display size (e.g., 600x200 pixels). This ensures the image is displayed at the correct size while taking advantage of the extra pixel density for sharpness.

Should I optimize all images in my email for retina displays?

While optimizing all images can improve overall quality, it may not be necessary for every image. Focus on images with text, logos, icons, or high-contrast elements, as these are most affected by retina displays. For photos or less critical images, the difference may be less noticeable.

What are the risks of not optimizing email images for retina displays?

Not optimizing images for retina displays can result in blurry, pixelated visuals that make your emails look low-effort and unprofessional. This can negatively impact your brand perception and reduce engagement rates among users with high-resolution devices.

Marketing Strategy & Technology Trends

How can keeping up with marketing technology trends improve my campaigns?

Staying current with marketing technology trends, such as optimizing for retina displays, allows you to adapt to changing customer behaviors and device usage. This can improve engagement rates, ensure your materials look professional, and help you maintain a competitive edge.

What is the impact of device upgrades on email marketing?

Device upgrades mean more users have access to high-resolution screens like retina displays. As a result, marketers must ensure their emails and images are optimized for these devices to avoid quality issues and maintain engagement with a growing segment of their audience.

Improving Email Image Quality on Retina Displays
By 4Thought Marketing

retina display

We take it for granted that a phone screen, tablet screen, computer monitor, or laptop will show us crystal-clear graphics. Blurry images tend to be blamed on malfunctions or just low-quality files. But the introduction of retina displays created another potential issue: an otherwise high-quality image displayed on a screen it wasn’t designed for.

What are Retina Displays?

Apple introduced Retina displays in 2010. Retina displays use twice as many pixels as standard displays, a design intended to make graphics even crisper. But increasing the screen’s pixel count doesn’t increase the pixel count of any images that the screen may be displaying. In other words, an image that looks fine on a standard screen might look blurry or even pixelated on a retina display.

The problem here is obvious. Not only are blurry images hard to look at (especially if they contain text), but they can also make your marketing materials look low-effort and unprofessional.

How Many People Use Retina Displays?

As of 2021, more than 113 million Americans (or 47% of all smartphone users in America) owned an iPhone. Meanwhile, in 2017, Apple estimated that there were about 100 million active Macintosh users, compared to Microsoft’s 400 million Windows 10 users. There’s also a 40% chance that these currently active users either bought their device recently or upgraded to the newest model when they could. All of these newer devices would have a retina display.

Let’s do a little math here. Between iPhone and Macintosh users, at least 213 million Americans regularly use Apple products as a primary or secondary device. 40% of them have recently upgraded to a new device. That’s 85.2 million Americans alone that regularly view websites and emails on a retina display!

Marketers focused on ROI tend to cater to the majority. If a few users don’t have the right technology or behavior to warrant nurturing, they may be brushed aside in favor of more profitable contacts. It may sound like retina display users can be safely ignored—they aren’t necessarily the majority, especially when the solution is so simple. But 85.2 million people is far too many to simply overlook.

Optimizing Images for Retina Displays

Since a retina display has twice as many pixels as standard displays, marketers should focus on doubling the number of pixels in their promotional images. Let’s look at email design for an example. Standard email width is 600 pixels, which will look blurry on a retina display. An email banner 1200 pixels wide will render much better.

To produce a retina display-friendly graphic, create the image with the doubled number of pixels. In the case of an email banner, that would be 1200 pixels by 400 pixels as opposed to 600 by 200. Save the completed image file. In your Eloqua email template, set the width and height in your <img> tag to 600 and 200 pixels respectively, then insert your high-pixel image. This allows you to retain the higher quality without disrupting your email formatting.

Of course, increasing pixel count usually means increasing the file size of the image. Since larger files take longer to load, only increasing pixel count doesn’t necessarily fix the problem. Use a file compression tool (like this one recommended by Hubspot, or this one from Website Planet) to decrease the file size while retaining as much image quality as possible. This way, you can keep the best of both worlds: high-quality, crisp images with a quick loading time.

Finally: consider which images in your email need the retina display treatment. The most noticeable differences in resolution show up in images with high-contrast elements, text, or geometric shapes. Many photos don’t have any of the above. While creating higher-quality versions of nonessential images certainly can’t hurt your campaigns, the extra time required to create them may not be worth it. To get the best retina display results quickly, stick to optimizing unique elements such as your logo, any icons in the email, and your branded font.

Keep Up with New Marketing Technology

Effective marketing teams know to keep up with customer behavior and developing trends. But your team should also keep track of new marketing technology, especially anything that impacts email as much as retina displays can. See how you can use these new developments to your advantage and improve your engagement rates.
