Form submission formspree?

Question

CMS

I came across a service for sending data from a form to mail: formspree.io We
insert the form into the site and when the user enters information there, it comes to the mail.
But the problem is that in order to work from a certain page, you need to pass verification.
I want to insert a form into the header of the site, so it will only work from verified pages.
It is necessary that the sending worked from all pages.
Are there similar services or something to do with it?

Answer 1

And to pass verification for the entire site, no?
Or maybe such a record is possible - mysite.com/*

Answer 2

In case the question is still relevant, here is a fairly detailed post on this topic. About formspree there is including.

Answer 3

There is an analogue of this service - formfarm.im
Absolutely free, plus it is devoid of the shortcomings that you voiced. Can be used without registration, but with registration there are more options!
Verification takes place by domain, so you can create pages as much as you like, no further verification is required
