Engagement, it's not what you might think

Most delivery experts will tell you that ISPs measure recipient engagement as a part of their delivery. That’s absolutely true, but I think there’s a language difference that makes it hard for senders to understand what we mean by engagement.
ISPs, and other filtering companies, profile their user base. They know, for instance, who logs in and checks mail every day. They know who checks mail every 20 seconds. They know who gets a lot of spam. They know who hasn’t logged in for months. They know who accurately marks mail as spam and who is sloppy with the this-is-spam button. They know if certain recipients get the same mail, it’s likely to be spam.
Engagement at the ISPs is more about the recipient engaging with their email address and the mail in their mailbox then it is about the recipient engaging with specific emails.

Questions about Spamhaus

I have gotten a lot of questions about Spamhaus since I’ve been talking about them on the blog and on various mailing lists. Those questions can be condensed and summed up into a single thought.

Email filters

What makes the best email filter? There isn’t really a single answer to that question. Different people and different organizations have different tolerances for how false positives versus false negatives. For instance, we’re quite sensitive to false positives here, so we run extremely conservative filtering and don’t block very much at the MTA level. Other people I know are very sensitive to false negatives and run more aggressive filtering and block quite a bit of mail at the MTA level.
For the major ISPs, the people who plan, approve, design and monitor the filters usually want to maximize customer happiness. They want to deliver as much real mail as possible while blocking as much bad mail. Blocking real mail and letting through bad mail both result in unhappy customers and increase the ISP’s costs, either through customer churn or through support calls. And this is a process, filters are not static. ISPs roll out new filters all the time, sometimes they are an improvement and sometimes they’re not. When they’re not, they’re pulled out of production. This works both for positive filters like Return Path and negative filters like blocklists.
Then there is mail filtering that doesn’t have to do with spam. Business filters, for instance, often block non-business mail. Permission of the recipient often isn’t even a factor. Companies don’t often go out of their way to block personal mail, but if personal mail gets blocked (say the vacation plane ticket or the amazon receipt) they don’t often unblock it. But when you think about why a business provides email, it makes perfect sense. The business provides email to further its own business goals. Some personal usage is usually OK, but if someone notices and blocks personal email then it’s unlikely the business will unblock it, even if the employee opted in.
In the case of email filters, the free market does work. Different ISPs filter mail differently. Some people love Gmail’s filters. Other people think Hotmail has the best filtering. There are different standards for filtering, and that makes email stronger and more robust. Consumers have choices in their mail provider and spamfiltering.

Recipients are the secret to good delivery

Many, many people hire me to educate them on delivery and fix their email problems. This is good, it’s what I do. And I’m quite good at helping clients see where their email program isn’t meeting expectations. I can translate tech speak into marketing. I can explain things in a way that shifts a client’s perception of what the underlying issues are. I can help them find their own way into the inbox.
But…
Most of what I do is simply think about email delivery from the point of view of a recipient and help clients better meet their recipient’s expectations. This works. This works really well. If you send mail that your recipients want your mail gets to the inbox.
Here’s the secret: ISPs and most spam filters have a design goal to deliver mail their users want. They only want to block mail their users don’t want.
Filters are not designed to block wanted mail.
Sure there are complicated situations where senders have gotten behind the 8 ball and need some help cleaning up. There are situations where filters screw up and block mail they shouldn’t (and aren’t quite designed to). Spam filters are complicated bits of code and sometimes they do things unexpectedly. All of these things do happen.
But these situations happen a lot less than most senders think. Most of the time when mail is hitting the bulk folder, or is throttled at the MTA the issue is that recipients don’t care about the mail.
Recipients aren’t engaged with a particular sender or particular brand. So ISPs react accordingly and that mail ends up slowly delivered or bulked. This upsets the senders to no end, but the recipients? The recipients often don’t care that some mail shows up in bulk or arrives Wednesday afternoon instead of Tuesday evening.
When recipients are engaged with a particular sender or brand, though? Delivery is fast and reliable. Mail is rarely delayed or bulked. When recipients want mail, they interact with it. They look in the bulk folder. They miss it when it’s not there. They complain to the ISPs when they don’t get it. The ISPs react accordingly and prioritize or “red carpet” that email.
The secret to really good delivery is to get your recipients to handle your ISP relations for you. Send mail they miss when they don’t get it, and you’ll discover most of your delivery problems go away.
