I'm Baz and I help small businesses save time and money and reduce stress - by making things happen automatically so you don't need to worry about them.
Have you ever been somewhere and they offer free wifi. You think "I've got an important Snapchat to send" so sign up. And then it asks you for your email address - and you just know that it's going to send you a giant bucket-load of crap.
Well, fear not, because the inventors of the internet have your back.
When they were setting things up, they realised that software developer types (like me) will need to test things. So they created an Internet address just for testing - example.com.
This means that when you sign up for that spam-crazy wifi but put your email address in as email@example.com - they will be busy sending out all that rubbish - but it's going straight to example.com, which, as a test account, just throws it all away.
So you get the benefits of a spam-free inbox. And hassle-free browsing.
