Are you blocking yourself?

One thing that catches me up with clients sometimes is their own spam filters block their own content. It happens. In some cases the client is using an appliance. The client’s reputation is bad enough that the appliance actually blocks mail. Often these clients have no idea they are blocking their own mail, until we try and send them something and the mail is rejected.

Typically, the issue is their domains are the problem. We mention the domains in email, and the filters do what filters do. We work around this by abbreviating the domains or calling, it’s not a big deal.
It’s a great demonstration of content filters, though. The content (the client’s domain) is blocked even when it comes from an IP with a good reputation. In fact, with Gmail I can often tell “how bad” a domain reputation is. Most mail I send from WttW to my gmail address goes to the inbox, even when the client is reporting bulk foldering at Gmail. But every once in a while a domain has such a bad reputation that any mail mentioning that domain goes to bulk.
Most folks in the deliverability space know the big players in the filtering market: Barracuda, Cloudmark, ProofPoint, etc. Those same people have no idea what filters their company uses and have never even really thought about it.
Do you know what filter your company is using to protect employees from spam?

Dodging filters makes for effective spamming

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 spam and tune filters. There’s just too much of it out there for it to be cost effective to manually review filters.
In some ways, though, automatic filters are easier to avoid than manual filters. Take a spam that I received at multiple addresses today. It’s an advertisement for lists to “meet my marketing needs.” I started out looking at this mail to walk readers through all of the reasons I distrusted this mail. But some testing, the same sorts of testing I do for client mails, told me that this mail was making it to the inbox at major ISPs.
What told me this mail was spam? Let’s look at the evidence.

Horses, not zebras

I was first introduced to the maxim “When you hear hoofbeats, think horses not zebras” when I worked in my first molecular biology lab 20-some-odd years ago. I’m no longer a gene jockey, but I still find myself applying this to troubleshooting delivery problems for clients.
It’s not that I think all delivery problems are caused by “horses”, or that “zebras” never cause problems for email delivery. It’s more that there are some very common causes of delivery problems and it’s a more effective use of time to address those common problems before getting into the less common cases.
This was actually something that one of the mailbox provider reps said at M3AAWG in SF last month. They have no problem with personal escalations when there’s something unusual going on. But, the majority of issues can be handled through the standard channels.
What are the horses I look for with delivery problems.

January 2015 – The Month in Email

It’s February already! January went fast, right? At WttW, we are gearing up for MAAWG SF later this month — will we see you there?
We started the year with a set of predictions about email. Mostly we think email will continue to be great at some things and not-so-great at other things, and we’ll keep fighting the good fight to make it better.
As always, I’m interested in filters and how spammers continue to work around them to reach the inbox. I also wrote about how the language of an email impacts delivery, and wrote an expanded response to a comment suggesting email filters should be illegal. You can guess where I stand on that (and if you can’t, perhaps you might read more about how email is an inherently malicious traffic stream…)
I also took a moment to point out a trend I’m really enjoying, which is the rise of content marketing (a.k.a. giving customers useful and interesting information they can’t find elsewhere). As I said in the post, I’ll be curious to see how ROI plays out with this strategy.
We also talked about some of the less exciting content we see in email, notably the infamous Murkowski Statement, by which a spammer declares “Nope! Nothing to see over here!”
Steve also pointed out some content shenanigans in the form of hidden preview text, with some additional clarification from the original marketer in the comments.
In industry news, the big story was that Microsoft has partially implemented DMARC for Office365, and was the first to make a public statement about the specific ways they’ve chosen to implement. In my post, I did a walkthrough of a message to illustrate a bit about how this works, which might be useful if you’re trying to wrap your head around DMARC implementations.
We also talked about consolidation in the ESP space, and got a number of comments from readers about who they think might be next. Shortly thereafter, Listcast was acquired by MailerMailer.
Josh noted a few major shutdowns: Yahoo China email services and the AHBL list. The latter explores the challenges inherent in decommissioning a blacklist, and there’s a good discussion in the comments, so you might check it out if you missed that earlier this month.
Josh also pointed to the Salesforce State of Marketing report, which is always a useful set of metrics about how marketers are using email and other channels. It’s definitely worth a read.
