Herramientas de campanas email para Accessible Email
Email accessibility ensures your messages are readable and usable by subscribers with visual impairments, motor disabilities, cognitive differences, and other accessibility needs. Beyond the ethical responsibility, accessible emails also tend to perform better for everyone because they are clearer, more structured, and more readable. Screen reader compatibility, sufficient color contrast, descriptive alt text, and logical heading structures are all practices that improve email quality across the board.

Preguntas frecuentes
Why does email accessibility matter for my email marketing?
Approximately 1 in 5 people have some form of disability that can affect how they use digital products, including email. Visual impairments, motor disabilities that affect how people navigate, and cognitive differences all affect email readability and usability. Beyond the ethical reasons for including all your subscribers, accessible emails often perform better for everyone because the same practices that help screen reader users also create clearer, more structured emails that are easier to scan and understand quickly. It is also increasingly a legal consideration for brands operating in the EU and some US contexts where digital accessibility requirements apply.
How do screen readers work with email?
Screen readers like JAWS, NVDA, and VoiceOver read the content of emails aloud to visually impaired users. They navigate the email using keyboard commands and follow the HTML structure to understand content hierarchy. They rely on alt text to describe images, heading tags to create a navigable structure, and descriptive link text to explain where links lead. The quality of the HTML structure your email platform generates directly affects how usable your emails are for screen reader users. Complex table layouts and non-semantic markup can make screen reader navigation confusing even when the visual email looks perfectly clean.
What is WCAG and does it apply to email?
WCAG (Web Content Accessibility Guidelines) is the internationally recognized standard for digital accessibility developed by the W3C. It is primarily written for websites but its principles apply well to email, particularly the contrast requirements, alt text requirements, and semantic structure guidance. WCAG has three levels: A (minimum), AA (recommended), and AAA (enhanced). Aiming for WCAG AA compliance in your emails covers the most common and impactful accessibility requirements. While there is no legal requirement specifically to make marketing emails WCAG compliant in most jurisdictions, the EU Accessibility Act is expanding requirements and best practices trend toward compliance.
What is the minimum color contrast ratio for accessible email?
WCAG AA requires a minimum contrast ratio of 4.5:1 for text under 18pt (or 14pt bold) and 3:1 for larger text. You can check contrast ratios using tools like the WebAIM Contrast Checker at webaim.org/resources/contrastchecker/ or browser extensions like Colour Contrast Analyser. Common failures in email design include light gray body text on white backgrounds (which often falls below 4.5:1), very light colored CTA text on light button backgrounds, and watermarked or low-opacity decorative text that is also used for actual content. Running your brand color palette through a contrast checker before using it in email templates saves you from recurring accessibility issues.
How do I write good alt text for email images?
Good alt text describes what the image shows and its purpose in the email context. For a product image, alt text might be "Blue ceramic coffee mug, 12oz, on a wooden table" rather than just "mug." For a promotional banner, describe the offer: "50% off all orders through Sunday" rather than "banner." For decorative images that add no informational value, use empty alt text alt="" to tell screen readers to skip the image. Avoid starting alt text with "image of" or "photo of" since screen readers already announce that it is an image. Think about what a sighted reader gets from the image and what a non-sighted reader needs to know to understand the same context.
Should I use image-only emails?
No. Image-only emails are one of the worst accessibility choices you can make. Screen readers cannot read text embedded in images, subscribers with images blocked see nothing useful, and accessibility is essentially impossible. Beyond accessibility, image-only emails often have deliverability problems since spam filters are suspicious of emails with no real text content. Every email should have real HTML text for the main content and use images only to enhance the message visually. If your designer is creating email mockups with text in images, that workflow needs to change to preserve the text as actual HTML.
