No idea whether it is POSSIBLE, but I think it is a really BAD IDEA. 

Compare it with normal (paper, snail mail) you send out to your clients. There, you have no guarantee if the recipient opened it / looked at it - unless you send it by "registered mail". 

You really want to send the newsletters as registered mail to your clients? If I were youre client, I would be a FORMER client as soon as I notice this. 

I know that this is not what you want to know - but I think you should re-think the idea at least twice...
