I have an CMS (TYPO3) that generates a html-page. This html-page I want to send with openemm as newsletter. In php-list par example I have only to include a tag like this into the text field:
So, you don't want to copy the code generated by Typo3 into the NL content but you want just to reference to this page? You can not force an email content to refresh itsself but have to provide a link to the external page which have to be clicked by the reader.
