I am not the poster, but I use RAR compressed files due to much better compression ratios, and speed of compression. Also the available commandline does come in handy for scripting etc.

Not the point, the point is that ZIP is a very common format and supported directly by the Windows OS, RAR is not.  The receiver needs to have some sort of program on their end to receive this as an attachment.  When you send a RAR attachment you'll probably find a number of receivers will ask you to send a ZIP archive instead. 

Again, my question, do you select to send RAR instead of ZIP when sending email attachments?  Unless I were to receive this sort of archive on my home system I'd not be able to use it.

Just add attachments in your email.
In the attachments tab you can send any file you want including rar archives.

Just like using ZIP archives however do not expect that all of your receivers will have the software that will allow them to use the RAR archive files.  FWIW, why do you want to use RAR rather than the more common ZIP?
