Postal Mail

Hello,

can someone tell my which moduls are out there to sent a postal mail over Whcms?

I found:

www.bluemailcentral.com
www.docsaway.com

Are there any others? bluemailcentral.com looks good to me (also the prices) but you are not be able to sent just 1 invoice... i mean you can select in the invoice Dropdown, to sent the invoice over email, but you are not able to sent the invoice over postal mail....


Really hope someone can give me some tips!


Thanks!
