How to pass information across domains to ask for newsletter only once?
- by Michal Stefanow
Lets assume following scenario, I have two sites:
example1.com
example2.com
When user visits 1 there is a prompt "please signup to a newsletter". Same thing happens when user visits 2.
However when navigating from 1 to 2 I don't want signup form to be shown.
My first thought were 3rd-party cookies, but it seems that they are blocked / not working:

Another thought is to append #noshow for each URL but that would require some work - for instance a script that would intercept click / tap events and modify URL structure depending on the address. (but that seems hacky)
I wonder if you know a robust well-established solution to this issue?
Thanks
