Typoed email addresses

By creating web domains that contained commonly mistyped names, the investigators received emails that would otherwise not be delivered.
Over six months they grabbed 20GB of data made up of 120,000 wrongly sent messages. BBC News

ESPs, complaints and spam

Steve wrote a while back about how Mailchimp handled his complaint.
Sadly, I have a counter example from recently.

Silly spam subject line of the day

It’s Friday, it’s been a long week and while I have things to say I’m looking for some entertainment.
What are your favorite spam subject lines?
Here are some of mine:
“Having rock-like winky is easy”(OK, I admit, sometimes I’m 12 and “winky” makes me laugh)
“-Enlarge-your ~Penis up to 3 per month!” (Up to three what per month? And every month?)
“-Its all about the bra-” (From yourscalecars, advertising penis enlargement. Uh. Really?)
“!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!” (apparently spammers never got the memo that !! is bad in a subject line)
“Adventures of my giant mighty soldier” (uh. back to being 12)
“Aliens spotted” (I always thought aliens were striped)
“allergic to almonds or pecans?” (well, no, but thanks for trying)
“anxiety’s archduke Bourbaki’s” (uh. What?)
And, well, I’ve gotten through the a’s in my spamfolder and there are something like 200,000 messages still to go.
Do share some of your own in the comments!

20% of email read on mobile phones

According to data published by Litmus this week.

It's easy to be a sloppy marketer

Sometimes marketers are just sloppy.
Take, for example, an email I received today from a company.
I wasn’t expecting it (sloppy #1).
I never consciously signed up for it (sloppy #2). Apparently I’d bought a package they sold through Appsumo and they claim I asked for future offers. If I did, I didn’t mean to.
The email itself used a template from the sender’s ESP, but whomever wrote the copy didn’t actually proof read it (sloppy #3).

A recipient's view on engagement

I found a blog post from a technical type talking about email engagement. This is a non-marketing way to do things, and probably won’t work for many marketing programs. But I think good marketers should be listening to what their recipients say, even if it’s counter-intuitive.
Edit 9/15: the website seems to have expired so I changed the link to the google cache of the article.

Appeals court rules in e360 v. Spamhaus

On August 30, 2007 I wrote my very first blog post: 7th Circuit court ruling in e360 v. Spamhaus. Today, 4 years later (almost to the day) that case may finally be over.

What's the best ESP?

I often get clients and potential clients asking me to tell them what the absolute best ESP is.
“You’re an expert in the field, which ESP will give me the best inbox delivery?”
The thing is, there isn’t an answer to that question.
ESPs have expertise in sending large amounts of mail. All have staff that manage and monitor MTAs. Most have staff that provide advice on delivery issues. Many have staff that handle abuse complaints, FBLs and blocks.
What they don’t have is magic delivery fairies or bat phones into postmaster desks.
Simply moving mail to an ESP won’t give you delivery. For the most part, delivery is the responsibility of the sender, whether they send mail through an in house system or through an ESP.
Delivery is primarily about how recipients react to a particular mail stream. Send mail recipients want, interact with and relate to and you usually see good delivery. The IP addresses or infrastructure contribute but do not dominate the equation. Sending from an ESP won’t fix poor content, irrelevant mail or unengaged recipients.
I can hear everyone now shouting at their screen “What about shared IPs!!!?!?!” Yes, yes, if you use an ESP with shared IP addresses and the ESP gets a bad customer you may see poor delivery for a time because one of their other customers was bad. It’s a fact, it happens. Plus, if you use an ESP with dedicated IPs and the ESP gets a bad customer you may see poor delivery for a time because one of the other customers was bad and their IP is near yours.
So clearly the answer is to bring email in house. That way no other company can affect your delivery, right? Yes. Kinda.
Are you willing to invest money in hiring email and DNS savvy sysadmins? Invest money in a MTA designed to handle bulk mail? Invest in an expert who not only understands bounce handling, but can explain to your developers what a good bounce handling system must do? Invest in someone who can manage authentication like DKIM? Who can handle delivery issues and understands how to talk to ISPs? Invest in development to write a FBL processor?
For some companies, the internal investment is the right answer, and bringing mail in house makes business sense.
For a lot of companies, though, they just want to use email to communicate with customers. They don’t want to have to invest in multiple staff members (as it’s very rare to find a single person with all the various skill sets needed) to just send a weekly newsletter, or daily sales email. They need a tool that works, they don’t need to know how to sign up for a FBL, they don’t need to know how to handle bounces. They can outsource that work and focus on the communication value.
Finding the best ESP starts with finding out how you want to use email.
Question 1: What role does email play in my business?

Just go read here…

I wrote earlier this week about bad ways to evaluate and choose an ESP. It was all going to end today in an insightful and profound post telling all of you exactly how to find the best ESP.
Then Smartinsights published an insightful and useful article on choosing an ESP yesterday.
So, yeah, just go read what Jordie has to say. I have a couple other things to add, but I’ll drop those in another post.

I do not think that means what you think it means

Yesterday, I looked at the analysis of ESP delivery done by Mr. Geake. Today we’ll look at some of his conclusions.
“Being blacklisted most likely suggests that sender IP either sends out to a great deal of unknown or angry recipients.” That’s not how most blocklists work. Most blocklists are driven by spam traps or by the personal mailboxes of the list maintainers. The only blocklist that took requests from the public was the old MAPS RBL, and I don’t believe that is the case any longer.
Blocking at ISPs is often a sign of sending out a lot of mail to unknown or angry / unengaged recipients. But most ISPs don’t make their lists public. Some allow anyone to look up IP addresses, and if we had the IPs we could check. But we don’t, so we can’t.
“[…] if you share this IP with Phones4U then only 62% of your emails will be accepted by a recipient’s email server. That’s before they hit the junk filter. I wouldn’t want to pay for that.” This conclusion relies on the Sender Score “accepted rate” number. Accepted Rate is a figure I don’t rely on for much. I’ve never been able to reconcile this number with what client logs tell me about accepted rate. For instance, I have one IP address that has a 4.4% acceptance rate. But I know that 19 out of 20 emails from this IP do not bounce. In fact, it’s rare to see any mail from this IP bounce.
The one thing that Mr. Geake gets right, in all of this, is that if you’re on a shared IP address with a poor sender, then you share that sender’s reputation. Their reputation can hurt your delivery.
But a dedicated IP isn’t always your best bet, either. Smaller senders may not have the volume or frequency required to develop and keep a good reputation on an static IP. In these cases, sharing an IP address with similar senders may actually increase delivery.
For some senders outsourcing the email expertise is a better use of resources than dedicating a person to managing email delivery. For other senders, bringing mail in house and investing in staff to manage email marketing is better.
Tomorrow: how do you really evaluate an ESP?
