Ask Word to the Wise

One of the challenges of writing a blog for 5 years is making sure we’re providing information our readers really want. I figure the easiest way to do that is to have you ask us questions about the things you want to know.
You can ask questions in the comments here, send them to laura-questions@wordtothewise.com or tweet them to me @wise_laura.

Let them go!

Unsubscribing should be so simple. Even if someone signed up for mail, senders should let them go when they unsubscribe. Unfortunately, there are a lot of senders that make it difficult to unsubscribe. In fact, many companies are still hiding unsubscribe links behind login pages.

Open Relays and Mail Sinks

Email is a “store and forward” protocol. The sender doesn’t connect directly to the recipient to send the mail with just one network hop, rather the sender connects to a mailserver (usually referred to as an “MTA”, short for Mail Transfer Agent) and sends the message there. Once that MTA has received the message it sends it on to another MTA, and so on until it reaches the recipient.
Mail clients typically don’t have any intelligence built in to them to decide which MTA to send an email to. Instead they’re configured to blindly send every message to one particular local MTA, the smarthost, which then does all the proper SMTP work to decide where to send it on to.

Questions about CAN SPAM.

In the US, the law governing the sending of commercial email is CAN SPAM. I’ve seen a number of questions about CAN SPAM recently.
One came from twitter, where someone was asking if just having an email address meant permission to send to it. Clearly, just being able to dig up an email address doesn’t imply permission to send marketing or commercial email to it. I can promise you April23@contact.wordtothewise.com did not sign up to receive information on increasing Facebook followers.
CAN SPAM doesn’t prohibit unsolicited email. All it says is that if you send unsolicited email you must do a few things.

Just Block It

I tend to go back and forth about reporting spam these days. On one level I know that it’s all a numbers game, and policy enforcement is more about the quantity of complaints than the quality. Knowing this I don’t often send in complaints. I do make a few exceptions: when I know the policy enforcement team or when it’s a current or former client.

Equivocating about spamtraps

What is a spamtrap? According to a post I saw on Twitter:

Dr. Livingston, I presume?

I linked to Al’s post about misdirected emails and how annoying it is for people who receive emails. I’ve previously talked about the problems associated with not handling misdirected emails properly.
It’s really annoying getting email that you never signed up for. For instance, one of my email addresses gets quite a bit of misdirected email. Oddly enough, much of this mail comes addressed to “Mrs. Christine Stelfox” and advertises various services. The problem is, I’m not Mrs. Christine Stelfox and I don’t live in the UK.
I’ve been getting this misdirected email for a while. In fact, I’ve even tried to track down the source of this just to make it stop. But I can’t seem to get that to happen. The senders tell me simply that I opted in, and that if I want to opt-out, here’s a link. Sometimes I have more luck contacting ESPs, but not always.
In fact, recently I reported spam to Mrs. Stelfox to a European based ESP. I got a response from their delivery head, who asked a lot of questions about the email address. What kind of spamtrap was it? How long had I had it? Is it possible it’s a recycled address? It’s really not, though. It’s an address I’ve had since early 1994, and it’s not really a trap as I still actually use if for some me. But I’ve not used it for commercial email since sometime in the late ’90s. And I’ve certainly never claimed to be a Mrs. Stelfox.
This really isn’t a case where I forgot I signed up. This isn’t a case where someone had the address before me. This is either some confused person using my address or some company in the UK selling my email address as belonging to someone else. I’ve tried to track this down in the past to get off the list of whomever is selling this address. But I’ve never had any luck.
There isn’t a lot of recourse here. I can continue to unsubscribe the addresses, but that doesn’t resolve the underlying problem. The underlying problem is that many marketers think it’s acceptable to purchase (or append) email addresses with no regard for the fact that sometimes their data suppliers are wrong.
It’s not just this one address, either. Another one of my email addresses is being sold as “Mrs. Laura Corbishley” of the UK as well. Sometimes I get the same spam to Mrs. Christine Stelfox and Mrs. Laura Corbishley. Other times I get different spams to each address, possibly because Mrs. Stelfox is behind some commercial email filters and Mrs. Corbishley isn’t.
Misdirected emails are annoying. They’re a problem for the people who keep getting them and can’t make them stop. It’s really important that ESPs, companies that send email and companies that sell email addresses have some way to make that mail stop. It doesn’t matter that half a dozen ESPs have put Mrs. Stelfox in their suppression list. Senders are still purchasing that data and are wasting their money. I am still getting spam.

Misdirected email

Al has another post about another company sending mail to a customer that gave an email address that didn’t belong to them. The person receiving the misdirected email has no effective way to make it stop, and is getting more and more frustrated with the ongoing spam. (Consumerist article)

Creative HTML Table Abuse

There’s an old-school ’90s HTML design trick that dates back to the dim and distant past before we had decent layout control in CSS. That’s “slicing” – chopping a large image up into multiple parts, then reassembling them in an HTML table.
If you slice your images in an email and the end user hasn’t loaded images what will they see? They’ll see a rectangular box – either empty or with the image alt text in it. And, if you set the background colour for the table cell, they’ll see that – but only when images are turned off.
If you’re sneaky, you can do clever things with that.
Images off:

The same mail with images on:

You can't technical yourself out of delivery problems

In many cases these days, many more cases than a lot of senders want to admit, delivery problems at the big ISPs are a result of sending mail recipients just don’t care about. The reason your mail is going to bulk? It’s not because you have minor problems in your headers. It’s not because you have some formatting issues. The reason is because your recipients just don’t care if the ISP delivers your mail or not.
A few years ago the bulk of my clients hired me to do technical audits for their mail. I fixed a lot of delivery problems that way. They’d send me their email and I’d run it through tools here and identify things they were doing that were likely to be causing problems. I’d give them some suggestions of things to change. Believe it or not, minor tweaks to headers and configuration actually did make a lot of difference in delivery.
Over time, though those tweaks less effective to fix delivery problems. Some of it is due to the MTA vendors, they’re a lot better at sending technically correct mail than they were before. There are also a lot more people giving good advice on the underlying structure and format of emails so senders can send technically clean email. I started seeing technically perfect emails from clients who were seeing major delivery problems.
There are a number of reasons that technical fixes don’t work like they used to. The short version, though, is that ISPs have dealt with much of the really blatant spam and they can focus more time and energy on the “grey mail”.
This makes my job a little harder. I can no longer just look at an email, maybe run it through some of our tools and provide a few suggestions that fix delivery problems. Delivery isn’t that simple any longer. Filters are really more focused on how the recipients react to mail. That means I need to know a lot more about a clients email program before I can even start to identify what might be causing the delivery issues.
I wish it were still so simple I could give minor technical tweaks that would appear to magically improve a client’s delivery. It was a lot simpler process then. But filters have evolved, and senders must evolve, too.
