TWSD: breaking the law

I tell my clients that they should comply with CAN SPAM (physical postal address and unsubscribe option) even if the mail they are sending is technically exempt. The bar for legality is so low, there is no reason not to. Sure, there is a lot of spam out there that does not comply with CAN […]

TWSD!

One important aspect of getting good delivery is to look like legitimate email. A big part of that is to not do what spammers do. More specifically, do not do the things that ISPs trigger on when identifying spammers. There are a lot of these “tricks” and “delivery techniques” used by spammers. They may seem […]

Just Leave Me Alone Already

I tend to avoid online sites that require you to register and provide information including email addresses. In my experiences companies cannot resist sending email and my email load is extremely heavy and I want less email, not more. Sometimes, though, what I need to do requires an online registration and giving an email address […]

Feedback loops: net benefit or net harm?

There has been a very long, ongoing discussion on one of my mailing lists about whether or not feedback loops are a net good or a net harm. I believe, overall, they are a net good, but there are people who believe they are not. The biggest objection is that the lawyer mandated redaction of […]

Don’t do this

I re cently received an email from someone I do not know. This email was welcoming me to the friends and family beta of a new website. This email got under my skin a bit and it has been one of those weeks and so I decided to reply to the email. “Whomever sold you […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment
