How to create an automatic blog post from a form submission?

I'm designing a Job Board. 

So everytime I receive an employment opportunity I'd like it to be posted automatically on the Blog as a Post. 

I receive it on my e-mail too. So I could use the e-mail as the input or the form itself. 

* Do you know how I could do this through Zappier? 
* Specific coding? 
* Using Mailchimp? 

You cannot post content to Squarespace, with or without code. 

You will need to use another platform to receive and host the data. This third-party service could be displayed within a Squarespace page through embedding or an iframe.
