I'm getting the following error when I error check an email
('This message includes HTML content that contains too many characters')
Has anyone come across this before? What's the fix?
Thanks
Richard
Hi Richard,
Please let me know whether your error could been solved after you reduce HTML source code size below 100kb.

Hello Richard,
As mentioned by Clofy Mao already, there were other threads already raised on this topic that you can look into:
- community.dynamics.com/.../html-this-message-includes-html-content-that-contains-too-many-characters
- community.dynamics.com/.../email---this-message-has-html-content-which-is-too-large
Possible reasons for the issue are the following:
1. Text content (include CSS rules) in your marketing email is larger than 100kb.
2. An embedded base64 format image which is larger than 100kb on your marketing email
100kb limitation documentation in the blue Important content box on the following URL:

Hi Richard,
You could take my anwser in the thread below as reference:
The final marketing email size(.html) should be less than 100kb.
