A contact form is available on your blogger widgets, but your messages are sent to the email you signed up to blogger with. If you are like most bloggers and have an email account only for enquiries then you should have a look at these options below.
This form is smart & spam free. I use foxy form on my blogs "contact me" page. You can enter your desired email address that all the messages will be sent to. You can also customize it. It is a copy & paste html code which you just paste into your wanted area of your website.
