It’s rare I find mail that violates the SMTP spec (rfc5321 and rfc5322). I’ve even considered removing “send mail from a correctly configured mail server” from my standard Best Practices litany. But today I got mail asking me to respond to a survey. This whole email is a mess of problems, and it’s claiming to be from the California Secretary of State. It’s...
The great folks over at Zettasphere and Emailmonday have released their Email Addiction Survey. Nothing surprising in the data that I can see, although I suspect one particular data point is going to surprise folks. Yup, more than 70% of people don’t really care about a do not reply address in a message. Honestly, I’m not surprised. Most users don’t really care. In all honesty...
You take a turn, I take a turn At the SMTP level email is very much a simple line-by-line text based protocol. The client sends a command on a single line, the server responds with one or more lines (the last one marked by having a space in the fourth column), and then the client sends another command. The main exception to that is when the client sends the payload of the email. Once the server...
As of 6pm UTC the fbl.returnpath.com website is down. Return Path are aware of the issue and are working to fix it. I haven’t seen any estimated time to fix.
But, it’s not just you and they are aware.
EDIT: And 30 minutes after I posted this, it’s back. All fixed! Go and submit your FBL changes.
Anyone actively handling deliverability issues has had the experience of submitting a ticket or email and receiving no response. Alternatively, we get a boilerplate response that seems to not address the question. It happens to me, it happens to colleagues, it happens to everyone. One of the biggest challenges we face is taking that lack of response and channeling it into action items for our...
There’s a whole belief system built around the idea that the best way to get good deliverability is to have your own dedicated IPs. In fact, senders regularly approach me to ask when is the right time for them to get a dedicated IP. They assume all their deliverability problems will disappear if they get a dedicated IP. Generally they’ve not asked the most important question: should...
It’s probably one of the most consequential midterm elections in the US ever.
Go Vote.
I was on the phone with a colleague recently. They were talking about collecting a bit of data over the weekend and mentioned how great it was they had the tools to be able to do this. Coincidentally, another colleague mentioned that when the subscription bombing happened they were able to react quickly because they had a decent tool chain. I’ve also been working with some clients who are...
Captchas – those twisty distorted words you have to decipher and type in to access a website – have been around since the 1990s. Their original purpose was to tell the difference between a human user and an automated system, by requiring the user to answer a challenge – one that was supposedly hard for computers to solve, but easy for humans. A few years later they acquired the...
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...
