Is email dead?

These last few years have been something, huh? Something had to give and, in my case, that something was blogging. There were a number of reasons I stopped writing here, many of them personal, some of them more global.

The gang is trickling in

It’s been a few years since we’ve actually made it to a MAAWG. We missed much of 2018 and 2019 due to our international move. Then 2020 San Francisco conflicted with a personal engagement. Then, well, pandemic hit and it’s been virtual and then we were moving and … wow, it’s been busy!

ESPs need to step up their compliance game

I don’t send a lot of spam complaints generally. Mostly I block and move on. There are some companies, though, that I offer the professional courtesy of sending a complaint or a report to their abuse@ address. Former clients, friends and colleagues generally get that courtesy.
