Content marketing

There are a lot of mailing lists I’m on simply because I can’t be bothered to unsubscribe. Every week or every few days mail shows up in my inbox. I may look at the subject line, I may even open the message. But most of it is not interesting. It’s yet another sale at Sur […]

Dodging filters makes for effective spamming

Spam is still 80 – 90% of global email volume, depending on which study look at. Most of that spam doesn’t make it to the inbox; ISPs reject a lot of it during the SMTP transaction and put much of rest of it in the bulk folder. But as the volumes of spam have grown, ISPs […]

Unsubscribing is hard

A comment came through on my post about unsubscribing that helpfully told me that the problem was I didn’t unsubscribe correctly.
