Starting today, you can create and manage multiple email aliases from a single Hotmail account.
Hotmail (and many other email services) already allow you to just add a plus sign (‘+’) and a descriptive word to the first part of your email address. For instance, if your email address was email@example.com and you wanted to create an alias for online shopping, you could use firstname.lastname@example.org. Email sent to this alias will still be delivered to your inbox or to a particular folder. This can help with managing different types of incoming email. In addition to the plus feature, we’ve also released Sweep to help manage this type of incoming email traffic.
However, with the plus addresses that many services offer, it’s still very easy to determine your actual email address and there are times when you simply don’t want to give out any part of your real email address – that’s where our new alias feature helps you out. Email aliases let you create completely different email addresses that you can use to receive email into your primary account without anyone knowing what your primary email address is.
Let’s say you’re in the market for a new car. There are a bunch of websites that will email you price quotes, sales alerts, etc. During your car search, these messages are helpful, but once you’re done, they become clutter that can be difficult to stop. By using an alias on these websites instead of your main email address, you can avoid this. And when you’re done, just turn the alias off, ensuring future unwanted messages that are sent to that alias don’t land in your inbox.
