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 = "[e-mail]"

[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)
      });
    }
