I came across a newsletter that had this at the bottom:
Each link was a single-click response in a form. I didn’t need to hit submit or anything else! Super convenient and effective. Here’s an example of a one-click form
It turns out you can do this with Google Forms and it’s actually pretty easy. I made a tool to help you convert your links.
Keep in mind that you need to know to generate pre-filled links with Google Forms before you can convert it to a single-click URL.
I’m using it to track feedback on my newsletter https://todotemplates.com (I can also change the URL to add meta data like the post title).
Hope this is helpful! Let me know if you have any questions or suggestions.
