RSS email campaigns not working for me : Does anybody use them?

RSS email campaigns not working for me : Does anybody use them?

I have been having quite a time with RSS email campaigns from Zoho. Support keeps telling me its fixed but after weeks it keeps coming back with the same errors. It's been a bit of a back and forth.  I was just wondering if anybody else has noticed that using RSS campaign 
  1. The email content does not show the correct preview of the feed 
  2. The update feed button does not update the feed (this invariably works)  
  3. The send preview, may not always send a preview including your current feeds items 
  4. When you schedule a campaign, the system doesnt find any new feed items eventhough you just added new items so you email didnt go out as expected 
I would be pleased to hear from you if you havn't had these problems or if you have.
Regards,
