“We follow all the best practices!” is a common refrain from many senders. But what does best practices really mean? To me the bulk of best practices are related to permission, technical setup and identity. Send opt-in mail. Follow the SMTP spec. Authenticate your mail with DKIM. Publish a SPF record. Don’t hide you domain whois behind privacy protection services. Honor...
RadioShack is putting their assets up for sale including more than 65 million customer records and 13 million email addresses. Many are up in arms about the sale of personal data including the Texas Attorney General and AT&T who both want the data destroyed. Part of the controversy is that RadioShack’s privacy policy states the collected data will be only used by RadioShack and its...
Some emails are more important than others. I know, I know, all emails are important, but really, some are more important than others. I’ve recently been decluttering by the simple expedient of enrolling in paperless statements for some of our accounts. We have a 1TB NAS, I’m not going to run out of storage space and I will have so much less paper to deal with. Plus, electronic...
Can a bad SPF record ruin your delivery, even though all your mail still passes SPF? Yes, it can. One of our clients had issues with poor delivery rates to the inbox at gmail and came to us with the theory that it was due to other people using their domain to send spam to gmail.

It’s the time of the year, when we celebrate a holiday by telling you about email.
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 La Table. It’s another promo from Macheist. Virgin America wants me to book a flight. All of these...
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 and filters are relying more and more on automation. Gone are the days when a team of people could manually review...
“Figure out what email is.”
SSL or Secure Sockets Layer is protocol designed to provide a secure way of transmitting information between computer systems. Originally created by Netscape and released publicly as SSLv2 in 1995 and updated to SSLv3 in 1996. TLS or Transport Layer Security was created in 1999 as a replacement for SSLv3.
