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.

Spamfilters are stupid

Ben over at MailChimp writes about spamfilters that are following links in emails resulting in people being unsubscribed from lists without their knowledge. I strongly suggest clients use a 2 step unsubscribe system, that does not require any passwords or information. The recipient clicks on a link in the email and confirms that they do want to be unsubscribed once they get to the unsubscribe webpage.
Even more concerning for me is the idea that people could be subscribed to emails without their knowledge. For some subset of lists, using confirmed (double) opt-in is the best way to make sure that the sender really has permission from the recipient. Now we have a spam filter that is rendering “click here to opt-in” completely useless. I am sure there are ways to compensate for the stupidity of filters. As usual, though, the spammers are doing things which push more work off onto the end user and the legitimate mailers.

Yet more data verification

Friday Al posted about data verification, building on discussions last week about Mr. Poopyhead’s article on open signup forms. He has a very insightful analogy, that I like and I am going to steal (emphasis from the original).

Data Integrity, part 2

Yesterday I blogged about eROIs contention that consumers should not be wasting the time of lead gen companies by filling in fake data. There were lots of good comments on the post, and I strongly encourage you to go read them if you are interested in different perspectives on the data issue.
One of the arguments I was making is that people are only going to give accurate information if they trust the website that is collecting information. I do, strongly, believe this. I also believe very strongly that websites collecting information need to do so defensively. It is the only way you can get good information.
This ties in with an earlier post about a website that collects email addresses from any visitor, then turns around and submits those addresses to webforms. Hundreds of mailing lists have already been corrupted by this group. They are a prime reason companies must design address collection process defensively. There are people who do bad things, who will take an opportunity to harass senders and recipients. This company is not the first, nor will they be the last to commit such abuses.
Taking a stand against abusive companies and people may be useful, but that will not stop the abuse. It is much easier to design process that limits the amount of abuse. For lead gen, in particular, confirmed opt-in is one way to limit the amount of bad data collected. As a side effect, it also results in less blocked mail, fewer complaints and better delivery.
