Re:

Hi Fabricio,

I think that's better than using too many primitives in your domain model,
which sometimes is also refered to as "primitive obsession".

Using custom types even for simple values makes them much more explicit. It
helps enforce invariants: e.g. an email type could validate itself, using a
string instead would need something external. It also makes code much more
redable.

Best
