Hello @LocalLoveESV ,
Unfortunately due to the sporadic nature of this glitch, our engineers are still reviewing what might be causing it - especially since it doesn't even seem to affect the same devices and mail app versions the same ways. For example, the issue occurred for me in both your original email and in the recreation I did with wholly replaced blocks and text. But it didn't occur in the Tier 2 agent's same device and app versions. I've submitted your case to the engineers for further review, so if and when there's an update they'll notify you directly.
In the meantime, there's a workaround for Android and iPhone they've seen have intermittent success, that your contacts could try. Ultimately including the webpage link for the email will be the most consistent thing you can do on your end.
Android: Update device settings to default settings. Settings > Display > Advanced > Font Size (OR) Display Size.
iPhone: Flip the phone to horizontal view, let the email flip horizontally, then flip the phone back to vertical. The email may re-display normally.
