Freebies are awesome and you'll never hear me say otherwise. However there is one implied caveat that many people fail to overlook. When you request a freebie, you'll almost always be asked for an email address. Why? Because the companies want to spam the ever loving bejesus out of you. (I believe that's the scientific term.)
Luckily there's an incredibly simple solution to saving your work or personal inbox from a flood of spam: make a new email!
The more permanent solution, and the one I suggest, is to make a free account on Gmail. If you want to enter a fake name, feel free! Heck, I even made my email super easy to remember and direct to the point. [email protected] or [email protected] and other variations will always be available.
If you're looking to avoid creating an account altogether, then Malinator is the way to go. It allows you to create a free and disposable email address with the simple click of a button. All email sent to that account will be automatically deleted, however you can never get an easy to remember address with this method.
If privacy is more your concern, then ProtonMail might be more up your alley. They offer secure, encrypted email based in Switzerland!
No matter what, make sure you use a freebie email account specifically for freebies!
