Sending Website or News?

Hi, Since my initial problem was solved so sufficently (and fast) it’s time too find a new one. No, not realy and not a problem.

I am just curious about what is the main difference between sending a designed newsletter and sending a website. I guess sending a website has more or less the same limitation as newsletter design? So, in which case should I prefer to send my nawsletter as webpage?

What is your experience? Your opinion?
Thanks Michael
