Jetpack

Quick summary

Images in blog posts using the single image block are distorted when viewed in Jetpack Newsletters on the Apple Mail app. The images do not scale responsively, resulting in distortion. Below can be seen a comparison of the same image from a newsletter, how it looks like in the Gmail app vs Apple Mail app on iOS:

A clear and concise description of what you expected to happen.

The images should scale responsively, maintaining their aspect ratio, without appearing squeezed or distorted regardless of the app used to open the email.
