Email tumbling - what is it and should marketers be concerned?

It's a Google thing that's going around

Email tumbling is an effective way for people to filter their incoming emails, by using variations of their Google Gmail address. It's a fairly new trick and switched on Gmail users are starting to get the hang of it. In time, it will grow...

To tumble an email, users just need to insert a "." or a "+" into the pre@ section of their email, before adding any other text. As long as the @xyz, post @ element of the address is correct, mail will land in their inbox.

Here's an example.  [email protected] is the root email address. [email protected] will work just as well. If Jane is feeling organised and wants to sort her inbox so that a filter auto-archives emails from her online shopping, then [email protected] will also be delivered successfully.

Clever Jane.

If you use a Gmail account you'll probably be familiar with the filter options. Email tumbling lets users set up filters to move emails around, auto-archive, forward, delete etc.  So when Jane buys online Gmail will deliver her Christmas Shopping emails into a file automatically, provided she sets a filter up based on her tumbled, festive address.

Should marketers be concerned - is it an indicator of a bad intent?

In the email validation business, we flag up emails that are indicators of possible bad intent. For example, Disposable Email Addresses (DEAs) are frequently and reliably linked with chargebacks.

Email Tumbling isn't a disposable address. It isn't necessarily undeliverable, or a spam trap either.
If your list contains a growing percentage of tumbled email addresses, you should monitor them to see whether they show any behaviour that is unusual relative to your non-tumbling accounts.

To continue with the Christmas example above, if you are only emailing Jane into her shopping filter, she may not read a single thing you send, even though everyone loved the hula-hoops she bought them. Email tumbling offers more inbox flexibility, but it could limit the touchpoint effectiveness for marketers to reach customers.

If you are not using a a proper opt-in process, look out. Tumblers could very easily be used to trigger squealers. For example if Jane uses [email protected] online, she can monitor who is using her email address to send stuff she didn't want to receive. Then it's just a quick tap on the spam button to report you for sending her something she didn't ask for.

Online fraudsters like email tumbling because it saves them time

Online fraudsters are an innovative bunch. They keep up to date with trends and quickly learn how to work the system. Like lab rats.

Email tumbling enables them to use multiple email addresses quickly, without having to set up different email accounts. It's a real time saver and if you are online all day trying to get accounts open with fraudulent addresses and stolen credit cards, time is a big issue. This opportunity for fraud is a real concern for online traders - how do you distinguish between Jane Doe+christmas and Lab Rat+stolencard?

We'll help you keep an eye on tumbled email addresses by changing our reporting system to include a new channel to report these addresses for you. In addition, we'll continue to add bad email addresses and those associated with fraudulent activity into our database, making it quicker and easier to check bad tumblers as time goes on.

What should you do about Email Tumbling?

At this stage, apart from setting tumbled addresses to one side and watching results, there isn't a lot marketers can do. On the optimistic side, honest email tumblers could give you an opportunity to engage more effectively, as they will be reading your emails if they are genuinely interested.

It will be interesting to see how the trend develops, and whether online forms will need to be adapted to capture root as well as tumbled addresses.
