Email notifications are difficult to read on mobile in portrait mode

Summary

In v2.2.4, the one-to-one (OTO) email notifications format has been changed to include the user avatar in the message as well as additional CSS, which causes the format of email notifications to scale vertically. This makes reading the email difficult on mobile email readers (such as Mail for iOS)

Environment

HipChat Server v2.2.4

Steps to Reproduce

1. Trigger a one-to-one (OTO) email notification by messaging an end user that is in offline status.
2. This will fire an email to the end user.
3. Have the end user read this email in their mobile email client (like Mail for iOS devices)

Expected Results

The message in the email should be easily readable

Actual Results

The message in the email is formatted in a vertical manner, making it difficult to read (compared to a HCS v1.4.2 email notification)

Correct (Old 142 template)

Incorrect (New 224 template)

Workaround

Aside from turning the phone to read the email in 'landscape' mode on your mobile device, there is no direct workaround at the moment.
