via
Synonym discussion
Sense: preposition/2
All four words can express the method or channel by which something happens. 'Via' is the most neutral and widely used in both casual and formal English, especially for digital communication ('via email', 'via the app'). 'Through' works very similarly but often implies a process with multiple steps ('through the application process') or an organisation acting as a filter ('through the bank'). 'By' is shorter and pairs naturally with method nouns that don't take an article ('by email', 'by post'), though 'by means of' is the formal counterpart. Use 'via' when the channel is a named or specific medium; use 'through' when emphasising the organisation or system that handled the transaction.

Etymology
Borrowed directly from Latin 'via', meaning 'road, way, path'. In Latin it was a noun; English repurposed it as a preposition in the 18th century, first appearing in travel writing to indicate a stopping point along a route. The broader sense of 'by means of' developed in the 19th century as transport and communication networks expanded.
