more stuff we'll have when will work on templates, so we don't require any complex solutions right now

maybe we can go further, because soon or later we'll need to have some sort of additional data, that we will import into our emails.
for example - unsusbsribe link, or links to social media. i think separated json file will work for us perfectly
