It would be nice to get better analytics on the device used by the clients if possible. Type of device (mobile or desktop, iPad, etc) , OS, program used to read it...all of that would be helpful.
Having those analytics would really help target the emails to the respective audience, and allow designers to better tailor code and designs for the emails being sent.
Is that possible?
As of right now, this is not something that we can do, but this is a great feature request. We'll definitely pass this along and track it. As with any feature request, we priritize these types of features based on our customer's feedback overall.
