What plugin do you recommend to send to different posts after publishing?

No, do not create a newsletter, I send my posts to different addresses to auto post to multiple social networks.

The “hellotxt” is good, but I can not enter “posterous” and also only handles short messages.

The “posterous” is good but does not include “Orkut” and “Identical.”

What do you recommend wordpress plugin to send to my various email addresses of my social networks?.

On the other hand I can use the system “feedmyinbox” but simpre the end of each posting appears unsubscribe link.
How I can do Paraque automatically remove that link?

Thanks for your attention.
