Over at the Exacttarget blog, there is a guest post up from Annalivia who handles much of the sender support (and about 15 million other things) at AOL.
On the nights before Christmas…
when the relays are groaning under the loads
and ISP admins start to turn into toads
they tear out their hair and cry in despair
“why’s all this mail coming out of thin air?”
Head over to read the whole thing.
This press release has been discussed in a lot of groups and sites I read. One of my favorite comments comes from one of the filter developers at a large ISP. He was asked “does the overuse/misuse of the this-is-spam button significantly affect the ability to do your job?” His response, reposted with permission,
Read MoreYesterday I talked about breaking through the script in order to escalate an issue. I briefly mentioned that I always start out following the script and using the channels ISPs have provided. There are a number of reasons to do this all of which benefit you, the sender.
First off, when you use the designated communication pathway at an ISP there is a record of your contact. There are procedures in place to make sure your communication is addressed and you get a response. When you’re escalating to an individual, you’re using their communication channel. IMs get lost, email ends up buried in the pile, other things come up and a week later you’re still waiting for your answer.
Secondly, when you use the designated communication pathway at an ISP your contact is logged and tracked. This means that if the person you’re used to dealing with gets another job, moves on or otherwise isn’t able to communicate with you any longer you have a history with that ISP. The next person to move into the position and deal with issues can see that you’re a legitimate sender with a history of dealing fairly and professionally with ISPs.
Thirdly, handling direct and personal escalations are often outside the official job description the people directly contacted. This means that when they come up for review, the work they’re doing for people who won’t use channels is not as important as the other work they do. Sure, they may get some credit for helping people with problems, but they may not get the review they should get. This hurts not just the senders who believe they shouldn’t have to follow channels but also those of us who do follow channels, particularly in the current business climate. Do you really want to lose that awesome person you use because some dork thought they were too good, too important to use the provided form and that awesome person lost their job because they didn’t meet their official work goals?
Fourth, you’re not the only one escalating. I had the opportunity to visit my friend Anna from AOL a few years ago. One morning both of us had to actually get some work done, so we were parked in her living room on laptops. I was astonished at the number of IM windows she was juggling constantly. We’re talking 20 – 30 separate windows open at once, many of them troubleshooting sender issues. After seeing that I do as much as possible through the official channels that AOL has provided. She is my friend, and a very good one, and I still avoid using her as a contact point unless there is some emergency.
Remember this next time you are searching for that email address of the person from that ISP that’s currently blocking your mail. Use the official communication channels where possible, and always use them first. Using back channels for issues where the intended workflow works causes a lot of overhead and doesn’t scale at all well.
Part 3 in an ongoing series on campaign stats and measurements. In this installment, I will look a little closer at what other people are measuring about your email and how that affects your reputation at the ISPs.
Part 1: Campaign Stats and Measurements
Part 2: Measuring Open Rate
Reputation at the ISPs is an overall measure of how responsive recipients are to your email. ISPs also look at how much valid email you are sending. Anything the ISP can measure and use to distinguish good mail from bad is used in calculating reputation.
Some of the major metrics ISPs use include the following.
Invalid Address Rates
The ISPs count how much mail from any particular IP address is hitting non-existent addresses. If you are mailing a large number of email addresses that do not exist (550 user unknown), this is a suggestion that your address collection techniques are not very good. Responsible mailers do have the occasional bad address, including typos, expired/abandoned addresses, but the percentage in comparison to the number of real email addresses is low. How low is low? Public numbers suggest problems start at 10% user unknowns, but conversations with ISP employees show they consider lower levels a hint there may be a problem.
To calculate bounce rate ISPs take the total number of addresses that were for invalid accounts and divide that by the total number of addresses that the sender attempted to send mail to. Rates above 10% may cause significant delivery issues on their own, rates lower that 10% may still contribute to poor delivery through poor reputation scores.
Spamtraps
ISPs pay a lot of attention to how much mail is hitting their “trap” or “bait” accounts. There are a number of different sources of these trap accounts: old abandoned email addresses, addresses that never existed or even role accounts. Hits to a trap account tells the ISP there are addresses on your list that did not opt-in to receive mail. And if there are some addresses they know about that did not opt-in, it is likely that there are other addresses that did not opt in.
Spamtraps tend to be treated as an absolute number, not as a percentage of emails. Even a single spamtrap on a list can significantly harm delivery. According to the ReturnPath Benchmark report lists with a single spamtrap had nearly 20% worse delivery than lists without spamtraps.
This is spam clicks (FBL complaints)
Complaints from users are heavily used by ISPs. This tells them directly how many people are objecting to your email. In this case, permission is removed from the equation. Even if a sender has permission to send email, the recipient can say “no, I don’t want this, it is spam.” The ISPs put more weight on what their users tell them than on what the senders tell them.
