News in the email space

Various things happening in the email space recently that are worth mentioning but don’t have enough to justify a whole blog post. Verizon announced a new umbrella company for the AOL and Yahoo media properties, including things like Engadget, Huffington Post. Based on the various press articles I’ve seen this doesn’t appear to affect the email handling for either […]

The categories they’re measuring are: Countries Spam ISPs Spammers Botnet Countries Botnet ISPs Botnet ASNs TLDs Nothing really surprising there, but it’s nice […]

CBL issues

I started seeing some folks complain about false CBL listings a few hours ago. I’m now seeing the same folks saying the listings are being removed. The symptoms look similar to what happened in November (mentioned here), but it appears the CBL team are on top of things and are working to rectify things quickly.

Dealing with blocklists, deliverability and abuse people

  • 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
