State of Email Deliverability

I had other posts in the pipeline, but saw a link to the Litmus 2017 State of Email Deliverability Report and decided that deserved a mention here.
There’s all sorts of interesting data there, and well worth a download and read. I was, of course, interested in the “most problematic subscriber acquisition sources.” Senders having blocking issues or blacklist problems in the past 12 months use list rental, co-reg and purchased lists more often than senders that didn’t have problems.

Senders acquiring addresses through list rental are 104% more likely to be blacklisted than senders not using list rental. And they’re 47% more likely to be blocked.
These stats are the primary reason that most ESPs don’t allow list rentals, purchased or co-reg lists. They cause blocking and blacklisting. The ESP ends up having to deal with lots of problems and clean up the mess.
I’m unsurprised that lead generation by giving something away (a report, ebook, whatever) is related to problems. Most of these forms do little to no data checking and accept any and all fake data. There are fairly simple ways to enforce better data, but that does limit the spread of the information.
I am surprised to see signup through direct mail and catalog sales is so bad. Unless maybe people don’t know how to say no when asked for an email address over the phone. I know it seems awkward to say no when asked for an email address. Maybe some folks are giving fake addresses. I sometimes say I don’t have email, or just tell them no, they don’t need one.
The white paper itself is well worth a read. Go download it yourself (but don’t give them a fake email address!).

Doing email right

Over on the MarketingLand website, Len Shneyder talks about 3 companies (Uber, REI and eBay) that do email right. In there he shows how the companies use email to further their business goals while understanding and meeting the needs of their customers.
Meeting the needs of recipients is the way to get your mail to the inbox. Send email that your users want, and they will tell the ISPs when they don’t get your mail. It’s sometimes hard to convince senders of this. Instead they want to tweak URLs or authentication or IPs or domains. But none of those things are what deliverability is all about. Deliverability is about the recipient. Deliverability is about the relationship between the sender and recipient.
Send to the right people – and the right people are those who have asked for and want your mail – and deliverability problems don’t materialize. Sure, every once in a while something might happen that throws mail into the bulk folder for one reason or another. But fighting to get to the inbox isn’t an every day thing. Instead, senders can focus on knowing their users and sending mail that makes them happy when it shows up in the inbox.

Engagement drives deliverability

Return Path released an white paper today offering the Secrets of Successful Senders. I don’t think any of my readers will be surprised that it boils down to identity, reputation, and engagement. Return Path treats these as separate things and I understand why they do. I think however, that the identity and reputation are supporting players to the overarching issue of engagement.

When I’m dealing with clients and troubleshooting deliverability problems and offering solutions, I focus on the root cause. To me the root cause is almost always a data problem. Either there’s a problem with data collection or there’s a problem with data maintenance. These problems result in mail going to people who don’t really want or care about it.
Yes, identity is important. But, realistically, anyone mailing through a decent ESP has SPF and DKIM in place, at least on some level. There may be better ways to authenticate, but the boxes are checked.
Yes, reputation is important. But here’s the thing, reputation just means that the ISP knows how users are going to react to an email. Reputation isn’t some nebulous concept made up by ISPs. It’s an actual measurement. It quantifies the history of an IP or a domain or a mail stream and says we know that this IP sends wanted mail. We know that this domain sends mail our users ignore. It’s a history. Past performance does indicate future results.
Identity says who a sender is. Reputation tells us that sender’s history of sending. Those are the two factors that enable ISPs to make delivery decisions. Mail comes in and the ISP looks at it. They use identity to determine what reputation to assign to a mail. Reputation drives delivery, whether into the inbox or the bulk folder.

Are seed lists still relevant?

Those of you who have seen some of my talks have seen this model of email delivery before. The concept is that there are a host of factors that contribute to the reputation of a particular email, but that at many ISPs the email reputation is only one factor in email delivery. Recipient preferences drive whether an email ends up in the bulk folder or the inbox.

The individual recipient preferences can be explicit or implicit. Users who add a sender to their address book, or block a sender, or create a specific filter for an email are stating an explicit preference. Additionally, ISPs monitor some user behavior to determine how wanted an email is. A recipient who moves an email from the bulk folder to the inbox is stating a preference. A person who hits “this-is-spam” is stating a preference. Other actions are also measured to give a user specific reputation for a mail.
Seed accounts aren’t like normal accounts. They don’t send mail ever. They only download it. They don’t ever dig anything out of the junk folder, they never hit this is spam. They are different than a user account – and ISPs can track this.
This tells us we have to take inbox monitoring tools with a grain of salt. I believe, though, they’re still valuable tools in the deliverability arsenal. The best use of these tools is monitoring for changes. If seed lists show less than 100% inbox, but response rates are good, then it’s unlikely the seed boxes are correctly reporting delivery to actual recipients. But if seed lists show 100% inbox and then change and go down, then that’s the time to start looking harder at the overall program.
The other time seed lists are useful is when troubleshooting delivery. It’s nice to be able to see if changes are making a difference in delivery. Again, the results aren’t 100% accurate but they are the best we have right now.
