The most basic way of sending an email is to send an individual one from an email account. This option is only recommended for very sporadic use, but for simple purposes such as sending a couple of emails a day to controlled addresses, it can be good enough.
Do not use this method to send emails in bulk to distribution lists or to customers with unknown email addresses. You risk being banned from your service provider due to anti-spam rules. See other recipes in this chapter for more options.
