How e-mails and postal Services are the same

Using e-mail services have become very common now because everyone has access to the internet every where they go, also its easier to access than a mailbox while on the go. But a good things about the postal services, are you know when you receive an important document it cannot be deleted. But the downfall to using a postal service, is mail can get lost and delivered  to the wrong house. But with e-mail we can retrieve the e-mail if it has been sent to the wrong e-mail address. But at the same time with postal-service its illegal to open others mail. But using e-mail, anyone can open it and not get penalized for it which could also lead to information getting stolen. Both of these services are very helpful but there are many pluses and minuses to using them. Postal services are helpful for sending care packages and such. E-mail is generally being used for sending information halfway across the world, or used in a workplace. The switch to just using e-mail is starting take into affect because it's a lot easier for everyone to communicate and sending letters is starting to become out of style. It's very rare now to have a pen pal sending letters back and forth because of e-mail.
