Added security with email address tags
Pretend your email address gets compromised from Gawker, and the hacker starts to use it on other popular platforms. You can use different passwords to help limit the risk of the hacker accessing your other accounts.
One added security measure is to use address tags that are accepted by email services like Gmail and Yahoo. Depending on what email service you use, you can use a +, -, or = after the local part of your email address to then add an email address tag. This will allow you to have a different email on record with various organizations, while still receiving notifications to the same address.
Here are some examples for some of our favorite companies: Gawker:yourname+gawker@gmail.com Sony: yourname+ps3@gmail.com Email promotions: yourname+disneyemail@gmail.com Expedia: yourname+expedia@gmail.com
