Confirming website registrations

Confirming email addresses during a website registration process is a good practice. It stops people from creating fake accounts, abusing  resources and using that site as a mechanism for harassment. But simply sending out a confirmation mail is not sufficient to prevent problems, particularly when everything about the process assumes that unconfirmed registrations are actually valid and not problem accounts.
I’ve had a couple recent experiences with companies attempting to use email confirmation, but failing pretty miserably. In each case a website set up a process where a user could register an account on the site. Both sites required confirmation of the registration email addresses as part of the process. But in each case there were some major failures that result in non-customers getting email.
Tomorrow I’ll talk about those two specific cases. I’ll also provide specific suggestions on how not to fall into the same trap and actually send opt-in email.

What a week!
An interesting look at best practices

The sledgehammer of confirmed opt-in

We focused Monday on Trend/MAPS blocking fully confirmed opt-in (COI) mail, because that is the Gold Standard for opt-in. It is also Trend/MAPS stated policy that all mail should be COI. There are some problems with this approach. The biggest is that Trend/MAPS is confirming some of the email they receive and then listing COI senders.
The other problem is that typos happen by real people signing up for mail they want. Because MAPS is using typo domains to drive listings, they’re going to see a lot of mail from companies that are doing single opt-in. I realize that there are problems with single opt-in mail, but the problems depends on a lot of factors. Not all single opt-in lists are full of traps and spam and bad data.
In fact, one ESP has a customer with a list of more than 50 million single opt-in email addresses. This sender mails extremely heavily, and yet sees little to no blocking by public or private blocklists.
Trend/MAPS policy is singling out senders that are sending mail people signed up to receive. We know for sure that hard core spammers spend a lot of time and money to identify spamtraps. The typo traps that Trend/MAPS use are pretty easy to find and I have no doubt that the real, problematic spammers are pulling traps out of their lists. Legitimate senders, particularly the ESPs, aren’t going to do that. As one ESP rep commented on yesterday’s post:

Confirmed opt-in

I spent the morning in multiple venues correcting mis-understandings of confirmed opt-in. The misunderstandings weren’t so much that people didn’t understand how COI works, but more they didn’t understand all the implications.
In one venue, the conversation centered around how small a portion of deliverability the initial subscription process affects. Sure, sending unwanted, unexpected email can and does cause reputation problems, but merely using COI as a subscription methodolgy doesn’t automatically give a sender a good reputation or good delivery. Senders using COI as a subscription practice need to also need to send relevant and engaging mail that their recipients expect to receive. They need to handle their bounces well and purge or re-engage inactive subscribers. They need to keep their complaints low and their responses high.
How you manage subscriptions is only one factor in reputation schemes, and even if the subscription method is COI other factors can negate any bonus involved.
The second conversation involved Ken challenging me on the comment I left on his quiz yesterday. I said COI wasn’t foolproof and he challenged me to explain how. I did, and he’ll be following up next week.

The great debate

While surfing around last night, I discovered that the email experience council is running a poll. “The Great Email Debate Topic #2 – Single Opt-In or Double Opt-In?”
The email blogs have been discussing the question for a few weeks now, since one ClickZ columnist decided to stir controversy by claiming that “it is impossible to grow a list using double opt-in.” The original column inspired many other people to comment on the issue.
This is really a tempest in a teapot. There are situations where no address should be added to a mailing list without some sort of confirmation or verification step. Senders must protect themselves from bad subscription requests and double opt-in is one way to do this. Likewise, there are situations where a single opt-in with good list management will create a very clean list. Double opt-in isn’t necessary to stop spam.
Senders who think that they can’t grow their list with double opt-in are already behind the 8-ball in terms of list management. Yes, lists will grow slower. In the present environment, many users are very used to submitting a registration to a web page and then looking in their mailbox for an email to complete the process. No longer is “double opt-in” a foreign concept. Social networking sites, web forums and mailing lists commonly use double opt-in.
The challenge is for marketers to construct a signup process that is engaging enough to convince users to check their mailbox and click on the link. Senders with good marketing strategy will be able to do this, when it’s necessary.
Not every mailing list has to be double opt-in, but every engaging list could be without decreasing the number of subscribers.
