Contacting agencies - don't delete job post notifications from ProZ

Those, who are familiar with ProZ, receive notifications on job posts on regular basis. Some translators delete these mails without even reading, if the language pair or job type is not of their interest. And that is a mistake. Jobs posts at ProZ can be a great source of new clients. An agency you are registered in will contact you directly and will not post a job. So, that means, the outsourcer is new for you and there is a chance to let him know of your talent.
What do I do. I read every job post notification, go to this outsourcer's Blue Board and find a link to his web-site. Then I can see if this outsources can be a potential client for me. Some agencies have interesting blogs available at their web-sites, so this can be an additional source of info as well.
