Email accessibility checkers are tools that automatically scan and detect issues that may prevent people with disabilities from accessing email content. These tools can check email content and formatting to identify potential accessibility issues, such as missing alternative text for images, low contrast between text and background colors, or missing headings or other structural elements.

There are many email accessibility checkers available, both free and paid. Some popular options include:


The WAVE web accessibility evaluation tool is a free browser extension that can check email content for accessibility issues. To use this tool, install the WAVE extension in your browser.

Note that these tools are not perfect, and may not catch every potential issue, so it is still important to review the email carefully and use your own judgment to ensure that it is as accessible as possible before sending it.
