For example if I send an email from my home IP address, people can see my location of where I am when I sent the email. If I used a VPN, and changed the location, people will think my device was in a different place than it actually was but in an email can give away that it was my actual device that sent the email?

edit: let's say I create an email and send an email, or create a website and post on the website, besides my IP address, what else gives away the device/location I am posting/writing from?

I'm sorry, I'm not very well versed in this technical aspect of communication so I apologize if I'm asking questions are unrelated or that don't make sense.

Let's say I create an email and send an email, or create a website and post on the website, besides my IP address, what else gives away the device/location I am posting/writing from? So someone said that posting on a website and sending an email are very different things, what is different about them in terms of finding out who send/created a blog or email?

I am asking about tracking a specific device and user rather than asking about finding out what kind of device is being used.

I am asking about tracking a specific device and user rather than asking about finding out what kind of device is being used.

Basically the situation is this:

Someone (Person A) created a blog and an email using fake credentials and a VPN. Person A said defamatory things and impersonated another person on a blog. Person B is now suing person A and is subpoenaing the blog site as well as Person A. However even though Person A is used a VPN, is there anything besides the IP address that could be used to identify person A and/or the device Person A used.
