I've been using Kontactr to include a contact form in to my blog because its free and have no limitation for using this service.
Recently, Kontactr included CAPTCHA which creates even more complicated for spammers to misuse the service. We can also now change the overall look of the type to go with the style of our websites. So without waiting any time lets get started. :)
Step 1: Take a look at Kontactr and signup.
Step 3: Login to Blogger and create a page form Pages tab (also known as “static page”) from your blog's dashboard . Give the page a title, like, “Contact US” or anything that you like.
Step 4: Paste the copied code (as told in step 2) and Publish the page.
That is it. However, you can also customize it so that it matches the background color of your blog.
There are some other options too, for example, instead of a form, you can have contact buttons too, it can be a simple button or can be a “popup” contact form.
