- in a gaggle of 20 individuals with epilepsy, at the very least one particular person could have photosensitive epilepsy, making flashing or too-bright visuals doubtlessly dangerous;
- out of 10 individuals on Earth, one has dyslexia. Globally, that’s corresponding to the complete inhabitants of Europe battling overly complicated textual content;
- in a gaggle of 100 individuals, 12 might need motor disabilities, which might make small buttons, hover-only interactions, or complicated navigation troublesome to make use of;
- in that very same group, 5 to 6 individuals would have disabling listening to loss, affecting their capacity to course of sound-based content material or depend on audio cues.
This highlights the variety of wants amongst e-mail recipients and the significance of constructing emails accessible to everybody.
Even after we observe accessibility pointers, some points can nonetheless go unnoticed.
That’s the place accessibility testing instruments turn out to be important — they assist guarantee each e-mail you ship has no accessibility points and is useful for all subscribers.
Electronic mail accessibility includes addressing a variety of disabilities requiring particular instruments to check and guarantee inclusivity.
Testing emails for photosensitivity triggers
Why take a look at: Visuals with three or extra flashes per second can set off seizures in individuals with photosensitive epilepsy.
What to check: Animations, movies shared within the e-mail, and coloration combos.
Testing instruments for animations
- Hint RERC (PEAT): Developed by the College of Maryland, this software verifies that your GIFs adjust to the beneficial limits on flashing frequency. It’s essential to obtain it to start out utilizing it.
What to do in case your animations don’t comply
In case your animations exceed the flashing limits outlined in WCAG pointers, on-line providers like Ezgif will let you simply decelerate or optimize their velocity.

Professional tip: Keep away from inserting multiple GIF per display screen. A number of animated components displayed concurrently can set off photosensitive epilepsy, identical to animations with greater than three flashes per second.
Testing emails for coloration blindness
Why take a look at: Emails that rely solely on coloration to convey that means could be inaccessible to individuals with coloration blindness, making it troublesome to interpret vital data. Moreover, poor coloration distinction — similar to shiny yellow on mild blue or mild grey on medium grey — could make textual content troublesome and even not possible to learn.
What to check: Coloration-coded components, similar to buttons, labels, charts, banners, and different visible indicators.
Testing instruments for coloration accessibility
- Coblis (Coloration blindness simulator): This software simulates how people with numerous varieties of coloration blindness understand your pictures, together with those that can’t see pink or inexperienced and those that see solely monochromatic tones;

- Accessible Colours: Checks the distinction of textual content and design components (excluding pictures, except you manually enter the colour values);
- WebAIM (Net Accessibility In Thoughts): That is a web-based software for evaluating distinction ratios between textual content and background colours. Provides outcomes for regular textual content, giant textual content, and graphical components;
- Distinction Checker by Lea Verou: Means that you can enter coloration values or choose colours from the palette to check distinction ratios, with visible previews supplied.

Testing instruments for e-mail code validation
- Accessibility Checker by Parcel: Evaluates e-mail compatibility with display screen readers and different assistive applied sciences. It ensures correct use of ARIA roles, alt textual content for pictures, semantic checklist construction,
components with alternate textual content, and the inclusion of lang attributes. Moreover, it checks textual content path for RTL and LTR compliance and way more; - Accessible Electronic mail: This software focuses on checking e-mail code for compliance with display screen readers, serving to you determine and resolve potential boundaries.

Testing instruments for basic e-mail accessibility
- Litmus: Supplies instruments to judge e-mail accessibility for customers with visible impairments and people counting on assistive applied sciences.
