Unsubscribe rates as a measure of engagement.

Over at Spamtacular Mickey talks about the email marketers’ syllogism.

  1. Anyone who doesn’t want our mail will opt-out.
  2. Most people don’t opt-out.
  3. Therefore, most people want our mail.

This clearly fallacious reasoning is something I deal with frequently with my clients, particularly those who come to me for reputation repair. They can’t understand why people are calling them spammers, because their unsubscribe rates and complaint rates are very low. The low complaints and unsubscribes must mean their mail is wanted. Unfortunately, the email marketers’ syllogism leads them to faulty conclusions.
There are many reasons people don’t opt-out of mail they don’t want. Some of it may be practical, the mail never hits their inbox, either due to ISP level filters or their own personal filters. Some people take a stance that they do not opt out of mail they did not opt-in to and if they don’t recognize the company, they won’t opt-out.
In any case, low levels of opt-outs or even this-is-spam hits does not mean that recipients want that mail. The sooner marketers figure this out, the better for them and their delivery.

Confirmed unsubscribe

Whatever one might think about confirming opt-ins I think we can all agree that requiring someone to jump through hoops and confirm an unsubscription request will just annoy that person.
Today I attempt to opt-out from a discussion list. It’s one I *thought* I had opted out of previously, but I could find no record of the request anywhere. OK. So I imagined unsubscribing, I’ll just unsub again and keep better records.
After digging through the headers, I find the unsub link and dutifully mail off my unsubscribe request. I then receive an email that requires I click on a link to confirm my unsub request. This causes me to grumble a bit. I have heard all the arguments about forged unsub requests and the various reasons this is good practice. I believe none of them. Requiring people to confirm an unsubscription request is bad practice.
In this case, the mailing list is a discussion list so there is no CAN SPAM violation. However, I know that some commercial mailing lists have also implemented confirm your opt-out request. For commercial mailing lists, this is a CAN SPAM violation. It’s also just plain rude. If someone says, “Stop!” then you should stop, no questions asked

Clicktracking link abuse

If you use redirection links in the emails you send out, where a click on the link goes to your server – so you can record that someone clicked – before redirecting to the real destination, then you’ve probably already thought about how they can be abused.
Redirection links are simple in concept – you include a link that points to your webserver in email that you send out, then when recipients click on it they end up at your webserver. Instead of displaying a page, though, your webserver sends what’s called a “302 redirect” to send the recipients web browser on to the real destination. How does your webserver know where to redirect to? There are several different ways, with different tradeoffs:
