Deliverability versus delivery

Deliverability is a term so many people use every day, but what do we really mean when we use it? Is there an accepted definition of deliverability? Is the concept different than delivery?
At a recent conference I was running a session talking about email delivery, senders and the roles senders play in the email industry and at that particular organization. The discussion went on for a while, and the subject of deliverability versus delivery came up. J.D. Falk had a comment about the difference that resonated with me. Paraphrased, he said:

Delivery is what happens to a particular email. It is what ISPs are most concerned about.
Deliverability is the delivery potential of a particular email. It is what marketers, commercial senders and ESPs are concerned about. Deliverability is more than just “can this email be delivered”, it is the sum total of factors that play into email marketing: relevance, structure, content, and reputation.

This was such an insightful comment. I can help clients improve their deliverability, but only if they’re willing to make some changes to what they’re doing. Deliverability not just telling the ISPs that the mail is good and that it should be accepted, but is more about sending mail that recipients want and that they will tell the ISPs they want.
When thinking about deliverability improvements you can make, remember that deliverabilty is not just the email, but the whole process from address acquisition through purchase.

Reputation: part 2

Yesterday, I posted about reputation as a combination of measurable statistics, like bounce rates and complaint rates and spamtrap hits. But some mailers who meet those reputation numbers are still seeing some delivery problems. When they ask places, like AOL, why their mail is being put into the bulk folder or blocked they are told that the issue is their reputation. This leads to confusion on the part of those senders because, to them, their reputation is fine. Their numbers are exactly where they were a few weeks ago when their delivery was fine.
What appears to have changed is how reputation is being calculated. AOL has actually been hinting for a while that they are looking at reputation, and even published a best practices document back in April. Based on what people are saying some of that change has started to become sender visible.
We know that AOL and other ISPs look at engagement, and that they can actually measure engagement a lot more accurately than sender can. Senders rely on clicks and image loading to determine if a user opened an email. ISPs, particularly those who manage the email interface, can measure the user actively opening the email.
We also know that ISPs measure clicks. Not just “this is spam” or “this is not spam” clicks in the interface, but they know when a link in an email has been clicked as well.
I expect that both these measures are now a more formal and important part of the AOL reputation magic.
In addition to the clicks, I would speculate that AOL is now also looking at the number of dead addresses on a list. It is even possible they are doing something tricky like looking at the number of people who have a particular from address in their address book.
All ISPs know what percentage of a list is delivered to inactive accounts. After a long enough period of time of inactivity, mail to those accounts will be rejected. However for some period of time the accounts will be accepting mail. Sending a lot of mail to a lot of dead accounts is a sign of a mailer who is not paying attention to recipient engagement.
All ISPs with bulk folders have to know how many people have the from address in their address book. Otherwise, the mail would get delivered incorrectly. In this way, ISPs can monitor the “generic” recipient’s view of the email. Think of it as a similar to hitting the “this is not spam” button preemptively.
This change in reputation at the ISPs is going to force senders to change how they think of reputation, too. No longer is reputation all about complaints, it is about sending engaging and relevant email. The ISPs are now measuring engagement. They are measuring relevancy. They are measuring better than many senders are.
Senders cannot continue to accrete addresses on lists and continue sending email into the empty hole of an abandoned account while not taking a hit on their reputation. That empty hole is starting to hurt reputation much more than it helps reputation.

Personal Contacts at ISPs: Part 2

I’ve talked quite a bit recently about working with ISPs and personal contacts. Today I have an example of what not to do.
One of my ISP friends informed me that another blogger published correspondence from an individual at that ISP, including the individual’s full contact information. The correspondence wasn’t a big deal, the blogger was assigned an IP address by their ISP that was previously used by a spammer. The ISP had a block on the address and he was contacting them to get the block removed. It was totally a misunderstanding on the blogger’s part and the blogger removed the info when the ISP contacted him. Still, once something is out on the net, it’s out there forever.
Don’t do that. Really. When someone at an ISP helps you, don’t go publishing their information on a blog somewhere. They will find out, even if it’s just because their mailbox explodes or their phone starts ringing off the hook with multiple calls about an “emergency” situation. It hurts the person who helped you, who now has to deal with a major increase in volume and work load, and they’re never going to help you again.
This also hurts the rest of us, as ISP employees retreat farther and farther away from contact with senders. Even those of us who are careful with contact information may find it hard to get responses when others in the field are spreading info around.
I know some ISPs can be difficult to get any information from. That’s part of my reason for publishing the ISP information page was to help people find the right contact information. I think it’s extremely important for delivery professionals to understand that you don’t need a personal contact at an ISP to resolve most issues. What you do need is a deep understanding of SMTP, a smattering of knowledge about DNS and HTTP, a firm grasp of privacy issues and an understanding of the dynamics of email.
