Many email service providers support plus addressing, which is a feature that lets you receive emails to your email account using variations of your email address.
This is enabled by default on our cPanel and Zimbra servers, so if you use Precedence for your email, you can use this feature.
The format is:
username+anything@domain.com
So, if your email address is:
john@example.com
...then any of the following email addresses are valid and will deliver email to your email account:
john+junior@example.com
john+newsletters@example.com
john+some-shady-website-asking-for-an-email-address@example.com
Not only does this allow you to quickly specify an unlimited number of unique email addresses for things like registering multiple accounts on a website, or testing; it's also an excellent way of identifying services that you've signed up for—if you find a service has sold your email address to spammers or has become compromised, you can block that specific email address.
You should send a test email using this format first to make sure it works before using it.
