Hi, We have successfully sent number of campaigns, but now we are getting the invalid content error while trying to create the following campaign (campaign data is on dropbox because message length limit): https://www.dropbox.com/s/jmx84s7obcllw1k/EmailCampaign.txt Note that successful and unsuccessful campaign only differs in the email content . Suspect some invalid char is causing problems, or is the size of the email maybe the problem? Thanks in advance. One more question ( realted) : Is it possible to encode Xcontent in base64 as we already do for the Subject and FromName. To avoid escaping/encoding problems in future?
