Visual Impairment

Learn how to simulate visual impairments in Parcel

Parcel gives you the ability to simulate a variety of visual impairments to help you design inclusive emails that can be read and understood by all. You can enable/disable any of these by accessing the Previews Controls menu in the upper right corner of the Preview. You can only have one filter applied at a time. Visual impairments can be applied to any Live or Inbox preview, in any view.

As an example, let's see how a colorful email looks with each filter.

The first photo contains 6 jackets, which are red, blue, dark blue, greenish grey, dark red and gray. The second photo contains an additional 6 jackets, colored black, white, blue, purple, orange, and red.
