It's a Gmail thing that's going around

Email tumbling is a simple way to filter incoming emails, by using variations of a Gmail address. 

To tumble an email, users just need to insert a "+" and their tumble text at the end of the local part of their email address (the bit before the @). 

Here's an example:

janedoe@gmail.com is the root email address.

janedoe+shopping@gmail.com is the tumbled email address.

Filtering an inbox with email tumbling

If you use a Gmail account you'll have 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 shopping emails into a folder automatically, provided she sets a filter up based on her tumbled address (janedoe+shopping@gmail.com).

Should you keep tumbled emails on your email marketing list?

When we clean email address lists we flag emails that are bad or might be connected to fraud.

Email Tumbling isn't a disposable address. It isn't necessarily undeliverable, or a spam trap either.

If your list contains a growing number of tumbled email addresses, you should keep an eye on them and check to see if there's a pattern. Maybe your tumbled emails are connected to bad transactions that trigger chargebacks. Or maybe their open rates are great and they're your most engaged audience.

If you are not using a proper opt-in process, look out. Tumblers are used to filter and report spam. For example if Jane uses janedoe+spam@gmail.com 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.

What should you do about Email Tumbling?
