Hi, I have read all of these comments. I was triyng to use yuor API but your HTML filtering or validator or whatever you use is poorly programmed, errors are not clear and not even using http://validator.w3.org/ to validate my code and then use your API I can't pass your filter. For example, this simple code: <html><head><title>Boletin</tiltle></head><body><table width="700"><tr><td>horrible API filter</td></tr></table></body></html> I got the error: [error_key] => json.invalid.value.no_script_tags
[error_message] => #/email_content: Field does not support script content. All is because of this simple property: width="700" if I use: width=\'700\' or width=\"700\" instead of width="700", it does not work neither. Can you please tell me how to fix this? I got all my code ready to send newsletter to 8000 contacts, why you just don't use the same filter you have on your website tool (Own Code), i don't have problems there, but i need to send multiple newsletter, that's why I need the API. When are we going to have a real validator? thi is urgent for my enterpresi, and I really don't want to move from Constant Contact, but my boss has less patience than me.
