The good people at email platform provider Fastmail (whom I've blogged about more than once previously ) are dealing with a distributed denial-of-service ( DDOS ) attack. Not fun. I feel for them. From Twitter :  Over the last two days, service has been interrupted sever…

This isn't the first time I've blogged about vegan SPAM , which is a sentence I never thought I would write. But here we are, and it's making my brain hurt. From VegNews: "Hormel Foods Corporation—known best for its canned meat product SPAM—is developing new p…

Multiple sources are reporting that Google Postmaster Tools (GPT) has returned. I've confirmed it myself; graphs and data are back. As previously mentioned , Google Postmaster Tools went down around October 4th (and DMARC reports ceased to be sent, around the same time). I…

Just recently, I shared my top five (plus) tips on how to be prepared to maximize deliverability success this holiday season. It's a starting point, and I hope you found it useful! But what if we take that to the next level? And by "we," I mean not me. Somebody e…

Here's one I almost missed, from a couple of weeks ago: According to Wired, Cloudflare is moving into the email security space . The goal? To better protect against email-delivered threats (think phishing). They see a gap there; one I've noticed myself.
