Cargo Features

mail-template has no features set by default.

[dependencies]
mail-template = { version = "0.6.1", features = ["handlebars-bindings"] }
handlebars-bindings = handlebars

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
