Winning friends and removing blocks

I do a lot of negotiating with blocklists and ISPs on behalf of my clients and recently was dealing with two incidents. What made this so interesting to me was how differently the clients approached the negotiations. In one case, a client had a spammer slip onto their system. As a result the client was […]

  • Friday blogging... or lack of it

    It seems the last few Friday's I've been lax on posting. Some of that is just by Friday I'm frantically trying to complete all my client deliverables before the weekend. The rest of it is by Friday I'm just tired. Today had the added complication of watching the Trumpcare debate and following how (and how soon) it would affect my company if it passed. That's been a bit distracting, along with the other stuff I posted about yesterday. I wish everyone a great weekend.1 Comment
