Thinking about filters

Much of the current deliverability advice focuses on a few key ideas: Authenticate your mail with SPF, DKIM and DMARC Use a dedicated IP. Monitor delivery. Clean your data. All of these things are absolutely things you should be doing, but senders can do all these things and still have cruddy delivery. These things are great and can help your mail deliver better. But they’re not enough to...

SaaS systems are spammer targets

There are probably hundreds of thousands of really awesome SaaS products out there. They provide a framework to do all sorts of stuff that used to be really hard to do. Almost all of them include some email component. They dutifully build the email piece into their platform and, because they’re smart, they outsource the actual sending to one of SMTP providers. They’re happy, their...

Transactional mail can be spam

Marketers have a thing about transactional mail. In the US, transactional mail is exempt from many of the CAN SPAM regulations. If they label a mail transactional, then they can send it even when the recipient has opted-out! The smart marketer looks for opportunities to send transactional mail so they can bother spam get their brand in front of people who’ve opted out. Enter the...

Resources for safer conferences

The MAAWG conference was held in Brooklyn a few weeks ago. Many positive discussions and sessions happened at the conference. But there was an incident of harassment during the conference where one participant assaulted multiple other attendees during late evening activities. I’m not going to speak too much to what happened as I wasn’t there. What I will say is that I am proud of my...

Marking mail as spam says what?

I wear a number of hats and have a lot of different email addresses. I like to keep the different email addresses separate from each other, “don’t cross the streams” as it were.   Recently I’ve been getting spam to my womenofemail.org address asking about the wordtothewise.com website. I’m not sure where Ms. Catherine Metcalf bought my Women of Email address or...

SPF and TXT records and Go

A few days ago Laura noticed a bug in one of our in-house tools – it was sometimes marking an email as SPF Neutral when it should have been a valid SPF pass. I got around to debugging it today and traced it back to a bug in the Go standard library. A DNS TXT record seems pretty simple. You lookup a hostname, you get some strings back. Those strings can be used for all sorts of things, but...

Jane! Stop this crazy thing!

One of the consequences of moving to Ireland is I’m unsubscribing from most commercial mail, including some lists I’ve been on for a decade or more. Sadly, many of the companies don’t ship to Ireland, or their shipping costs are prohibitively expensive. Even if I wanted to purchase from them, I couldn’t. This process has made me realise how horrible many company’s...

Spamhaus DBL

Over the last few months I’ve gotten an increasing number of questions about the Spamhaus DBL. So it’s probably time to do a blog post about it. Last year I wrote about the DBL: DBL is the Domain Block List. It lists domains and not IP addresses. I’ll be honest, I don’t have as much experience with the DBL as with other lists, but I have had a few clients on the DBL. DBL is tied into...

Twilio acquires Sendgrid

Woke up this morning to the news that Sendgrid has been acquired by Twilio in an all stock deal. This fills a gap in Twilio’s platform, they didn’t seem to have any email capability before. I’m wondering how this will shake out in the broader email industry. Sendgrid is one of the biggest providers of SMTP services and have a significant customer base. I’ve worked with a...

Good morning DMARC

I’m thinking I may need to deploy DMARC report automation sooner rather than later.

… and so on, and on, and on for a lot further down the mailbox.
