We are an executive search and staffing firm using a shared email server (shared with other search firms who use PC Recruiter) for notifying job seekers about our open positions. I have a feeling, based on the diminishing responses we've gotten over the course of the last couple years, that some ISPs might be blocking the emails from going through. This is very frustrating since we have legitimate opportunities, we're not selling penis enlargement pills. We are also protected as a search firm under the CAN-SPAM ACT because email is our primary form of communication and we are not requiring job seekers to purchase a product or service. Furthermore, under CareerBuilder and Monster's Terms of Service, it clearly states that candidates who make their contact information available (they have the option to be anonymous), may be contacted directly by third parties. And we go out of our way to use advanced search functionality to increase the likelihood that the people we contact are a match for the position in order to reduce spam. But I have a feeling other companies using the server are abusing it and hurting our effectiveness. Also, there are job seekers that neglect to take down their resume from the job boards after finding employment and then get frustrated when receiving emails about other opportunities and are loose with the spam button. Anyway, the bottom line is that I would like to set up an email server that will get these emails inboxed but still use our cloud-based applicant tracking software (ATS) that houses our database of candidates, helps prevents us from sending duplicate emails to the same email address, manages our unsubscribe list, and allows us to filter by zip code radius. The ATS allows us to choose an outgoing SMTP server, user name and pword. I'm hoping that it is possible to set up a proxy server and whatever else is needed to guarantee the emails get inboxed and need an expert consultant who can help us get this set up. We're not going to pay for something that gets us 50% of the way there. I am looking for someone that is capable of fully delivering. I'm not a programmer but I can sniff out BS. Please don't waste our time. I've learned a great deal from this site from an SEO standpoint and I understand the damage a social media attack to damage a company's reputation can have on a business. So if you deliver, you will get paid. I have no interest in tarnishing my or my company's reputation.
