Well, yes and no...
I used to be a subscriber to Government Computing News and Federal Computing Weekly, which are pretty close. They have a print edition and online offerings.
They also have these related publications.
Look at the Demand Generation portion of the GCN For Advertisers section for info on what sorts of submissions they accept: https://publicsector.1105media.com/pages/gcn#demandgeneration
Post a whitepaper or educational asset in the GCN.com whitepaper library for lead generation.
The sponsor proposes the webcast topic, prepares the content and presents in this moderated format.
But that's going to cost a bit.
Another option... these publications make public their editorial calendar.
Editorial Calendars, for example:
From GCN: https://publicsector.1105media.com/pages/gcn-calendar
From FCW: https://publicsector.1105media.com/pages/fcw-calendar
That allows you to coordinate your content marketing endeavors with the upcoming topics they're covering in their publications.
Using the SkyScraper Technique you can produce epic, relevant posts that are better positioned to get shares and backlinks, aligning with those content calendars.
Then you can get scrappy doing cross-linking on Twitter, linking in their comments, infographics etc that get their attention and help build your list.
Just a start.
Hope this helps!
