Conclusions and recommendations
Many companies, including quite large and famous ones, do not pay due attention to transactional letters. This is fundamentally wrong.
If you approach the issue correctly, you can get a certain profit in the form of increased brand awareness, increased website/store traffic, increased click-through rates for newsletters, and some other parameters – up to and including increased sales.
At a minimum, transactional letters need to be beautifully designed, adding elements of corporate style. And at a maximum, additional elements can be placed inside service letters: links to important sections of the site, to sections of the catalog, to mobile applications, etc.
The main principle is not to overdo it. Useful information about the transaction should remain in the first place (the main focus).
