Is this a BUG REPORT or FEATURE REQUEST?:
bug

What happened:
With formspree after the form post call was succesfull the formspree redirect page "https://formspree.io/thanks" is giving "Access to XMLHttpRequest has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

What you expected to happen:

• Succesfully sending the form

Environment:

• Hugo version: 0.74.3/extended windows

As far as I can see this is a setting on formspree's side of things. If you have a specific example, we might be able to dig into it more.

I've copied the contact fragment, did some minor changes and added a few more input in the form.
I've created the form on formspree and associated with google ReCaptcha.
My formspree plan is the free one.

this is my .md

+++
fragment = "contact"
date = "2020-11-18"
weight = 120
form_name = "contact_form"

subtitle  = ""
post_url = "https://formspree.io/f/xxxxxx" #default: formspree.io
button_text = "Invia"
formspree = true
email = "[email protected]"

[message]
  success = "Messaggio inviato, verrai ricontattato al più presto"
  error = "Impossibile inviare l'email. "

[recaptcha]
  sitekey = "xxxxxxxxxxxxxxxxxxxxxx"

Let me know if you need more info about it

Thanks in advance

Use libraries that have cors handling, for example if you are using javascript instead of using fetch use axios or jquery, another alternative is to use cors proxy.

const send =(e)=>{
e.preventDefault();
axios.post('https://formspree.io/f/xxxxxxx', new FormData(e.target) )
.then(response => {
        if(response.status===200){
          setTimeout(() => {
            setMsg("Success");
          }, 5000);
        }
      })
      .catch(error => {
        console.log(error)
      });
    }
