Some people chose to make their E-Mail address public for other people to see, here are some ways you can format it.
Let's say that your E-Mail is "firstname.lastname@example.org", but you don't want to get spam mail, some good ways to not get spam is make the address only readable by a human, so you might chooses to write your E-Mail as: "gtrix2 [at] yahoo dot com", "g t r i x 2 @ y a h o o . c o m", "gtrix2 //@// yahoo ///./// com", or any other way a bot might struggle to read.
Displaying your address in plain text is okay, but using the URI scheme can also be a benefit to some people, so that rather than copying your address entering it into an email client by hand, a person can just click the address and have it open in their client.
