I've had an issue with my RSS feed and the emoji images WordPress replaces by default.
My content had emojis, so they would get replaced to images in the feed. Then, Mailchimp would use width: 100% on all images from my posts. Which, when you think about it, is great because it makes sure my images look good in desktop and mobile (email clients).
The issue was, the emoji images would also get a wide width. As you can imagine, the emoji images were massive.
To fix that, I've created a super straight forward plugin with help from Stack Overflow.
You can filter it everywhere if you need to: https://wordpress.stackexchange.com/questions/185577/disable-emojicons-introduced-with-wp-4-2
