Today I’d like to dig into that a little more and talk about the non-permanence of email addresses. A common statistic used […]

Spam is not a moral judgement

Mention an email is spam to some senders and watch them dance around trying to explain all the ways they aren’t spammers. At some point, calling an email spam seems to have gone from a statement of fact into some sort of moral judgement on the sender. But calling an email spam is not a […]
