The following features and areas aren’t supported.

- Email Template Builder isn't supported in Government Cloud.
- API usage for Email Template Builder isn’t supported and you can't create Email Template Builder email templates using the API. For example, if you use the API to update the HTML Value field, the value in Email Template Builder is out of sync.

Email Template Builder and Email Content Builder have these limits.

    In the HTML Value field of the HTML component, clicking **Format** can push you over the character limit. In that case, you can't save your template. Undo the formatting or shorten the HTML and add another HTML block for the rest of the content.
