The Paubox Rust SDK is the official async Rust client library for the Paubox Email API and Paubox Forms. All methods are async and return Result<T, PauboxError>, making them composable with any Tokio-based application.

paubox = "0.1"
tokio = { version = "1", features = ["rt-multi-thread", "macros"] }
