Enable Plus Addressing

Introduction

Plus Addressing is a great way to quickly create custom email addresses based off your standard email address, by simply adding a “+” suffix string to an existing email address.

For example, a plus address for [email protected] could be something like [email protected] that she could use to sign up for the newsletter at the Northwind web site.

Then when Northwind sends a newsletter to [email protected] it will route directly to [email protected]

We recommend you enable plus addressing.
