I picked up an interesting discussion on linkedin about free PR tools that could be used online. I wanted to share them on this post so that you could use them or test them for your next campaign (I know I will).
Follow the link to this site (avangate) and you will find a list of 50 sites where you can submit your press release for free. Someone also recommended three other sources on the forum:
They also mentioned to be careful because submitted to some of these services could generate some spam emailing to your inbox, so perhaps it is worth doing an test with an alternative mailbox.
Keep me posted if you have any comments or insights on this – will report back when we have tried them out.
