An E-Mail Account:

Inbox: Inbox is the main folder in your email account. It contains all the e-mails that have arrived in your e-mail account. You can click on inbox to see the mails that you have not read (shown in bold) as well as the mails that you have already read (in normal font) 

Sent Mail: It shows all the e-mails sent by you from your e-mail account. 

Drafts: This folder stores those messages that you have created but have not been sent by you so far. These messages are saved by you for more work.  Spam: Spam is unsolicited e-mails or junk mails. It is generally e-mail advertising sent to group of people. We can also term spam as unwanted e-mails. Spam mails are also a big cause of computer viruses. Spam mails are identified by the mail services and placed in this folder. These spam mails are automatically deleted after few days. 

Trash: Any deleted mail is put in the Trash folder. Trash folder allows you to get back an e-mail which have already been deleted. But it is important to know that you can get back the mails only within few days from trash after its deletion. After few days, mails are permanently deleted from trash folder. 

An email account, in general has the following options:

 Compose Mail: Composing is addressing, writing, and sending an e-mail message. By clicking on the Compose Mail button a window appears where we can write our message in the message box and the email addresses of the person we want to send the mail.   

 Contacts: The Contacts helps you to find email address of a person whom you have saved in your Contact list. We can also quickly find email conversations associated with a contact, and store additional information about our other persons whose email id is stored in our contacts (such as a mailing address, title, phone number, etc).
