How to Track or Filter Email Providers for Email Campaign Traffic
I'm not a GA professional so please forgive me if I do not use the correct terminology.
Essentially, I'm trying to find out how many users are opening my email campaigns with Gmail.
How do I find out the email providers my audience is using from the traffic that lands on my website through my email campaigns?
I wonder if there is a special type of tracking I need to set up or if this information that can already be found in GA.
