Things Email Service Providers do to your code.
A list of things that Email Service Providers do to your HTML code, intentionally or not.
If your ESP is messing with your HTML code (and you can't do anything about it), it can lead to unexpected results, like broken layouts and poor-performing campaigns.
Email developers like their code untouched. Esploated documents issues with HTML email code in ESPs.
Any poor soul interested in these kind of things. Mainly #emailgeeks.
Glad you asked!
