MailDrop is a free throwaway e-mail address. It's temporary. It's transient. It's disposable. It's meant for those times when you don't want to give out your real address. Just give someone any e-mail address in the maildrop.cc domain, come back here, put in the e-mail address, and you can see that inbox.
MailDrop offers the ability to give out a quick e-mail address to any site or app, then after you've established more trust with that site, you can give them your real e-mail address.
MailDrop helps to stop your inbox from getting flooded with spam from that one time you registered on a site which got hacked.
MailDrop can be used to get your receipt for your e-commerce purchase, without signing up to be spammed on a regular basis with "latest offers".
In short, MailDrop can help you cut out the amount of junk in your inbox.
