We often talk about confirmed opt-in (aka “closed-loop opt-in” or “double opt-in”) as the gold standard for address acquisition for permission-based mail. It’s not the only way to gather permission, and in some ways it’s a rather blunt tool that can discourage people from completing a sign-up process if it’s done badly – the confirmation email...
Why is bounce handling so hard
It should be easy, right? Except it’s not. So why is it so hard? With one-on-one or one-to-few email it’s pretty simple. The rejections typically go back to a human who reads the text part of the rejection message and adapt and makes the decision about future messages. The software handles what to do with the undeliverable message based on the SMTP response code. In the case of a 5xy...
It's not fair
In the delivery space, stuff comes in cycles. We’re currently in a cycle where people are unhappy with spam filters. There are two reasons they’re unhappy: false positives and false negatives. False positives are emails that the user doesn’t think is spam but goes into the bulk folder anyway. Fales negatives are emails that the user does thing is spam but is delivered to the...
Relaying Denied
I’ve got multiple clients right now looking for insights about bounce handling. This means I’m doing a lot of thought work about bounces and what they mean and how they match up and how different ISPs manage delivery and how different ESPs manage delivery and how it all fits together. One thing I’ve been trying to do is contextualize bounces based on what the reason is. Despite...
End of an era
A few moments ago, I cancelled one of my email addresses. This is an address that has been mine since somewhere around 1993 or 4. It was old enough to vote. And now it’s no more. I am not even sure why I kept it for so long. It was my dialup account back when I was in grad school in Delaware. When I moved to Madison to work at the university, I kept it as a shell account and email address...
Confirmed Opt-In: An Old Topic Resurrected
Looking back through my archives it’s been about 4 years or so since I wrote about confirmed opt in. The last post was how COI wasn’t important, but making sure you were reaching the right person was important. Of course, I’ve also written about confirmed opt-in in general and how it was a tool somewhat akin to a sledgehammer. I’m inspired to write about it today because...
From the archives: Taking Permission
From February 2010, Taking Permission. Permission is always a hot topic in email marketing. Permission is key! the experts tell us. Get permission to send email! the ISPs tell us. Marketers have responded by setting up processes to “get” permission from recipients before adding them to mailing lists. They point to their privacy polices and signup forms and say “Look! the recipient gave us...
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...
Subscription transparency
I regularly tell clients to be transparent with their sends. With email, permission is better than forgiveness. A surprise change in mail frequency or type leads to complaints. Complaints lead to bulk foldering. Once mail is in the bulk folder, it’s hard to get out of there, particularly at some webmail providers. The permission is better than forgiveness is hard for a lot of senders to...
Asking for help with a blocklist
There are often questions arising about how to go about getting off a particular blocklist. A few years ago I led the MAAWG effort to document what to if if you were On a Blocklist (pdf link). That document was aimed primarily at MAAWG members and deliverability experts with working knowledge of blocklists. I think, even now, it’s a good background on how to deal with a listing and mail...
