What about Tom?

I use tom@hotmail.com as my default bogus email address. Tom has subscribed to so many things because of me. This is why address verification doesn’t work. The address tom@hotmail.com is a real address. It exists. It accepts mail. And at least one person admits to signing up Tom for mail that the person doesn’t want. […]

The death of IP based reputation

Back in the dark ages of email delivery the only thing that really mattered to get your email into the inbox was having a good IP reputation. If your IP sent good mail most of the time, then that mail got into the inbox and all was well with the world. All that mattered was […]

Spam makes only 200MM dollars a year

Now, in a new paper in the Journal of Economic Perspectives, Justin Rao of Microsoft and David Reiley of Google (who met working at Yahoo) have teamed up to estimate the cost of spam to society relative to its worldwide revenues.

Gmail and the bulk folder

Earlier this week Gmail announced they were providing reasons for why they delivered a particular mail to the bulk folder. I’m sure a lot of senders are rejoicing over the clear feedback. After all this is exactly what they’ve been asking for “tell us why you’re filtering our mail and we’ll fix it.” I am […]

Content, trigger words and subject lines

There’s been quite a bit of traffic on twitter this afternoon about a recent blog post by Hubspot identifying trigger words senders should avoid in an email subject line. A number of email experts are assuring the world that content doesn’t matter and are arguing on twitter and in the post comments that no one […]

Email fingerprinting

I’ve had a lot of people ask me about what I mean by email fingerprinting. It means that I’m able to tell these 4 emails were all sent by the same entity. The domains are (mostly) different, the To: addresses are different, but I get hundreds of these emails a day. Different domains, different products, […]

Poor delivery can’t be fixed with technical perfection

There are a number of different things delivery experts can do help senders improve their own delivery. Yes, I said it: senders are responsible for their delivery. ESPs, delivery consultants and deliverability experts can’t fix delivery for senders, they can only advise. In my own work with clients, I usually start with making sure all […]

  • Friday blogging... or lack of it

    It seems the last few Friday's I've been lax on posting. Some of that is just by Friday I'm frantically trying to complete all my client deliverables before the weekend. The rest of it is by Friday I'm just tired. Today had the added complication of watching the Trumpcare debate and following how (and how soon) it would affect my company if it passed. That's been a bit distracting, along with the other stuff I posted about yesterday. I wish everyone a great weekend.No Comments


  • Indictments in Yahoo data breach

    Today the US government unsealed an indictment against 2 Russian agents and 2 hackers for breaking into Yahoo's servers and stealing personal information. The information gathered during the hack was used to target government officials, security employees and private individuals. Email is so central to our online identity. Compromise an email account and you can get access to social media, and other accounts. Email is the key to the kingdom.No Comments


  • Blogging

    It's been a wild week here in the US. I have to admit, the current political climate is affecting my ability to blog about email. I've always said email is not life or death. And how can I focus on the minutia of deliverability when things are in such turmoil and uncertainty? There are many things I want to write about, including some resources for those of us who are struggling with the current administration and changes in the US. What we can do. What we must do.  It just takes work and focus I don't have right now.    1 Comment
