Disposable or Temporary Addresses

Mark Brownlow has a really good post up today about disposable and temporary addresses and how they affect marketers trying to build an opt-in list.
I use tagged addresses for all my signups, and have for more than 10 years now. It lets me track who I gave an address to and if this mail is contrary to what I signed up for or the address has leaked, I can shut down mail to that address entirely.
Tagged addresses also have another function. One of our local brew pubs has a rewards program, spend money there, get points. As part of the signup process, they requested an email address. All the email I have received from them has been clearly branded, well designed, they are an example of how to use email right. That is until last week. Last week I received an email to the tagged address from some survey company. The survey company provided no branding, nothing.

My first thought was that our local brew pub somehow leaked my information out and I was getting some weird phishing or tracking spam. After a bit of examination and looking at the survey (again, not branded and with HTML looking like it was done in 1997) I did realize that this was probably a real survey commissioned by the brewpub and outsourced to someone else who executed it badly.
Recipients signing up to lists with tagged or disposable email address can be some of the most savvy customers. If marketing and emails are done well, this kind of customer can be a bonus. If marketing and emails are done poorly, the subscriber will leave.

That's spammer speak

I’ve been hearing stories from other deliverability consultants and some ISP reps about what people are telling them. Some of them are jaw dropping examples of senders who are indistinguishable from spammers. Some of them are just examples of sender ignorance.
“We’re blocked at ISP-A, so we’re just going to stop mailing all our recipients at ISP-A.” Pure spammer speak. The speaker sees no value in any individual recipient, so instead of actually figuring out what about their mail is causing problems, they are going to drop 30% of their list. We talk a lot on this blog about relevancy and user experience. If a sender does not care about their email enough to invest a small amount of time into fixing a problem, then why should recipients care about the mail they are sending?
A better solution then just throwing away 30% of a list is to determine the underlying reasons for  delivery issues, and actually make adjustments to  address collection processes and  user experience. Build a sustainable, long term email marketing program that builds a loyal customer base.
“We have a new system to unsubscribe people immediately, but are concerned about implementing it due to database shrink.” First off, the law says that senders must stop mailing people that ask. Secondly, if people do not want email, they are not going to be an overall asset. They are likely to never purchase from the email, and they are very likely to hit the ‘this is spam’ button and lower the overall delivery rate of a list.
Let people unsubscribe. Users who do not want email from a sender are cruft. They lower the ROI for a list, they lower aggregate performance. Senders should not want unwilling or unhappy recipients on their list.
“We found out a lot of our addresses are at non-existent domains, so we want to correct the typos.” “Correcting” email addresses is an exercise in trying to read recipients minds. I seems intuitive that someone who typed yahooooo.com meant yahoo.com, or that hotmial.com meant hotmail.com, but there is no way to know for sure. There is also the possibility that the user is deliberately mistyping addresses to avoid getting mail from the sender. It could be that the user who mistyped their domain also mistyped their username. In any case, “fixing” the domain could result in a sender sending spam.
Data hygiene is critical, and any sender should be monitoring and checking the information input into their subscription forms. There are even services which offer real time monitoring of the data that is being entered into webforms. Once the data is in the database, though, senders should not arbitrarily change it.

Signup forms and bad data

One thing I frequently mention, both here on the blog and with my clients, is the importance of setting recipient expectations during the signup process. Mark Brownlow posted yesterday about signup forms, and linked to a number of resources and blog posts discussing how to create user friendly and usable signup forms.
As a consumer, a signup process for an online-only experience that requires a postal address annoys and frustrates me to no end. Just recently I purchased a Nike + iPod sport kit. Part of the benefit to this, is free access to the Nike website, where I can see pretty graphs showing my pace, distance and time. When I went to go register, however, Nike asked me to give them a postal address. I know there are a lot of reasons they might want to do this, but, to my mind, they have no need to know my address and I am reluctant go give that info out. An attempt to register leaving those blanks empty was rejected. A blatantly fake street address (nowhere, nowhere, valid zipcode) did not inhibit my ability to sign up at the site.
Still, I find more and more sites are asking for more and more information about their site users. From a marketing perspective it is a no-brainer to ask for the information, at least in the short term. Over the longer term, asking for more and more information may result in more and more users avoiding websites or providing false data.
In the context of email addresses, many users already fill in random addresses into forms when they are required to give up addresses. This results in higher complaint rates, spamtrap hits and high bounce rates for the sender. Eventually, the sender ends up blocked or blacklisted, and they cannot figure out why because all of their addresses belong to their users. They have done everything right, so they think.
What they have not done is compensate for their users. Information collection is a critical part of the senders process, but some senders seem give little thought to data integrity or user reluctance to share data. This lack of thought can, and often does, result in poor email delivery.
