The information presented within this guide is aimed at website owners seeking to learn the ropes of web accessibility. Technical elements are described in layman’s terms, and, as a rule, all topics pertaining to the legalities of web accessibility are presented in as simplified a manner as possible. This guide has no legal bearing, and cannot be relied on in the case of litigation.

It’s estimated that 4.3 billion people have an email account. To put that into perspective, that’s over half the global population.

However, in their basic form, emails are not fully accessible to everyone.

People with certain motor disabilities may not be able to access an email if they are forced to use a mouse or keyboard. People who have visual impairments and who rely on assistive technologies to read emails, may not be able to fully understand them if they lack alt text and other elements. 

Creating accessible emails is therefore critical to avoid discriminating against the disability community. And, while everyone should do their part in providing equal access to people with disabilities, most businesses are mandated by law to ensure that the emails they send are accessible, under the Americans with Disabilities Act.

In this blog we’ll explore the importance of creating and sending emails that comply with the Americans with Disabilities Act (ADA). We’ll show you how to create ADA-compliant emails using Gmail and Outlook, and provide detailed instructions on creating accessible emails using email marketing platforms, like Mailchimp, HubSpot, and Constant Contact.

What is the ADA?

The Americans with Disabilities Act (ADA) exists to prohibit discrimination against people with disabilities. Enacted in 1990, the ADA is the most important American law regarding civil rights and accessibility for people with disabilities.

The goal of the ADA is twofold:

  1. Ensuring employers provide employees with disabilities with the necessary accommodations to perform their jobs
  2. Ensuring that businesses make it possible for people with disabilities to properly access their products and services

Do emails need to be ADA-compliant?

To understand how the ADA applies to businesses, we need to look at ADA Title III, the section of the law that pertains to the way businesses serve customers.

Under ADA Title III, businesses considered “public accommodations", such as museums, real estate agencies, banks, colleges, hotels, and many small businesses, must be accessible to people with disabilities. Effectively, however, almost all businesses provide services and accommodations to the public, and ‌therefore must follow this law.

A common consensus has emerged in recent years that the ADA applies to the online world, as well. Today, courts in the U.S. apply the ADA to businesses’ emails and other online communication. 

If your business needs to be ADA-compliant, this means that the emails sent by your business also need to be compliant.

ADA compliance: important and beneficial

When you prioritize accessibility, you allow people with disabilities to access information and content without barriers.

Achieving ADA-compliance can also yield considerable business results. 
​The disability community’s spending power is immense. By making your emails more accessible, you invite more people with disabilities to become your customers. Additionally, it is essential to remember that accessibility is ultimately about human-centered design. Although this can be essential for people with disabilities, it also benefits every single person who receives your emails. 

It's important to note that when a business doesn’t comply with the ADA, it risks facing legal action, including receiving demand letters and potentially facing lawsuits. These can have a damaging affect on your business' reputation.  

ADA requirements for email accessibility: a breakdown

Even though the ADA is interpreted to include the online domain, there’s a lack of clear technical guidelines and requirements for areas such as email. However, standards that apply to web accessibility can shed light on what is expected of business owners in terms of email accessibility, as well. 

The Web Content Accessibility Guidelines (WCAG) are the standards that website owners are referred to by U.S. courts in cases involving ADA compliance violations. Created by the World Wide Web Consortium (W3C), WCAG 2.1 (i.e., the most up-to-date version of these standards) includes a wide range of recommendations for making websites more accessible for people with disabilities. These include (but aren’t limited to) adding alternative text to meaningful images, adding captions to meaningful videos, ensuring there is sufficient contrast between text and backgrounds, and ensuring compatibility with screen reader technology.

Here are the most essential elements you will need to address for your emails to conform to WCAG:

Adding a descriptive subject line

With a clear and descriptive subject line, your email recipients know exactly what they’re clicking on. This improves user experience in general, but it’s especially helpful for people who use screen readers to understand an email’s relevance to them.

Proper use of headings

When you use clear headings in your emails, it’s easier for those who receive them to understand the structure and hierarchy of content appearing within the email. This is helpful (and oftentimes, necessary) for people who use screen readers or have certain disabilities that make reading more challenging.

To allow screen readers to identify headings, be sure to use HTML headings like <h1> and <h2> rather than relying on style elements like colors or bold text.

Clear and simple language

One of the key principles of WCAG is to make text content readable and understandable. In practice, this means avoiding unusual words and abbreviations in your emails. You should also write clearly and simply.

Meaningful link text

Meaningful link text is critical for people with visual impairments who rely on screen readers to access emails. Much like descriptive subject lines, meaningful link text will provide proper context and help email recipients decide whether clicking on the link is relevant to them. 

When you add a link to your email content, make sure the link text clearly indicates to readers what they're clicking on. For example, “Learn more about how our services can help you” is a meaningful link text, whereas “click here” isn’t.

Sufficient color contrast

To make your emails accessible for people with low vision or color blindness, it’s important to use sufficient color contrast between text and its background. WCAG requires a minimum contrast ratio of 4.5:1 for text and images of text. However, the contrast ratio should be at least 3:1 for:

  • Text with at least 18 point (24px)
  • Bold text with at least 14 point (18.5px)

To check whether the contrast of your email font and background colors conforms with WCAG, you can use color checker tools such as Colour Contrast Checker or Are My Colors Accessible. You also might want to check out our guides on selecting ADA-compliant fonts and ADA-compliant colors.

Alt text for images

Alt text, or alternative text, describes an image so that people who are blind or have vision impairments can understand it via screen readers. According to WCAG, alt text should be added to meaningful images. The latter are images that are relevant to the text surrounding them and provide readers with important, useful, and critical information. Images that are displayed purely for decorative reasons should not have alt text added to them. 

Alt text is also important in cases of “image blocking” in which the email provider doesn’t show the image and only includes the alt text. When this happens, alt text will be essential for all email recipients (including those who do not have disabilities), as it will provide some form of context as to what should be appearing in that section.

Good alt text is descriptive yet concise, and allows your audience with vision disabilities to “see” your image as clearly as possible.

It’s worth noting that it is bad practice to send emails consisting solely of images as certain people with disabilities will find them difficult (if not impossible) to properly understand.

Responsive design

Even if you design an email that appears perfectly on desktop devices, it’s not guaranteed to look the same on mobile. Sometimes, email templates can resize on mobile devices and be difficult (or even impossible) to read correctly. This is more likely if you use a multi-column template that needs to resize on different screens and can lose its intended order.

Most popular email marketing platforms offer responsive templates that reduce the risk of display issues. Regardless, be sure to preview your emails on different devices before sending, especially if you edit the template.

It is important to note that achieving ADA compliance requires that your website, along with other web-based applications (like your PDF files), conforms to WCAG. We recommend you check out our ADA website compliance checklist to ensure you are covering all bases.
