Summary:

• Using mail() method one can send various types of mails such as standards, html mail.
• The mail() method opens the SMTP socket, attempts to send the mail, closes the socket thus is a secure option.
• mail() method should not be used for bulk mailing as it is not very cost-efficient.
• The mail() method only checks for parameter or network failure, thus a success in the mail() method doesn't guarantee that the intended person will receive the mail.
