How Does Your Email Sound?

As email marketers, designers, and developers, we care a lot about how our emails look in our subscribers’ inboxes. But have you ever asked yourself how your email sounds? It’s not something we think about a lot, but it’s a critical component of email accessibility.

Can screen readers read emails?

The short answer is: Yes.

Screen readers and their underlying software translate the interface and content seen on a screen into audio. More and more people rely on screen readers to help them consume digital content—including emails—so optimizing your messages for screen readers is becoming increasingly important for brands. You don’t want your email to sound like a garbled mess that listeners can’t understand or take action on.

With screen readers on the rise, the sound of your email matters

The World Health Organization estimates there are around 2.2 billion people with visual impairments, many of whom are considered blind. This has increased the need for screen readers to read content aloud, allowing people with low vision and blindness to use modern devices.

The Founder and Executive Director of free screen reading software NV Access, Mick Curran, said:

“For those of us without sight, computers don’t work straight out of the box. Software called a ‘screen reader’ is needed to translate visual information verbally, so we can make sense of what is on screen. Screen readers open up so many doors and, for example, allow us to learn, interact, or shop online.”

Screen reader software isn’t exclusive to people with disabilities, though. The recent proliferation of voice assistant software—like Amazon Alexa, Apple’s Siri, and Google Assistant—mean that assistive technologies have effectively gone mainstream. According to industry tracker, smart speaker users rose to 90.7 million in the U.S. alone in 2021, a 92% increase since 2018.

Since the COVID-19 pandemic, more people than ever are using voice assistants to get news, do their shopping, and, yes, even check and reply to their emails. But, too often, brands don’t consider the audible email experience and fail to make their emails accessible to screen readers.

This doesn’t sound right: When emails don’t work with screen readers

Screen readers work by looking at the underlying code of an interface—in our case, an email—and translating it into audio that reads the interface out to the user. For any online content, if your code isn’t complying with accessibility best practices, the screen reader’s audio output may not be usable. But the quirkiness of email development comes with unique challenges for people relying on screen readers.

For example, many emails contain images. However, without ALT text, screen readers have no way of properly describing the image out loud.

Let’s look at this really simple email header from one of our own emails. This header contains an image of the Litmus logo without ALT text.


Here’s how a screen reader will read out our email header, if we hadn’t optimized it for accessibility.

That isn’t very helpful, is it? Now imagine an email full of images. Subscribers would have to wade through a lot of markup garbage to get to the actual content. The screen reader’s audio would likely be unusable—and your email’s content would be inaccessible for anyone relying on a screen reader.

“Trying to access content that doesn’t comply with key accessibility best practices is a frustrating experience,” remarked James Boreham, General Manager at NV Access, “and many content creators aren’t even aware that they’re excluding a significant portion of their audience.”

James Boreham exclaimed, “Giving content creators insights into how screen readers translate their content helps surface the need for accessibility optimization to the people in charge of content creation.
