That’s because we all have different minds. Likewise, email clients use different business database rendering engines, and that’s why you get inconsistent results. Or at least, it’s one of the main reasons why. Why is email client rendering a problem? If we only had to worry about a handful of popular email clients, maybe rendering inconsistencies wouldn’t be such a big deal. Unfortunately, it gets much more complicat than that.

Won't Find One

There are thousands of possible ways an HTML email could be render. That’s because there’s more than just the rendering engine at play here. For starters, there are preprocessors that messages go through before reaching the rendering engine. These preprocessors try to remove code that could B2B Phone List present security risks, but sometimes they remove things that cause rendering issues. Preprocessors for different email clients can even change the code before a message is deliver bas on what they believe to be secure.
