Email headings should be well structured. This will help screen readers easily navigate content.

Specifying "alt text" for these images helps screen readers describe the image.

Larger paragraphs of text should be left-justified to improve readability for some readers.

Without a [lang] attribute, screen readers will assume the email is in the default language the subscriber chose when setting up their screen reader. If your email is not in that user’s language, the screen reader may not accurately transcribe your message.

Emails should have a "meta content-type" and defined character set.

Table roles should be clearly defined. This helps screen readers determine how to interpret the table.
