Handlebars alternatives
Providers that compete with Handlebars on at least one of: Templates
Minimal logic template language used across email systems.
Switching as developers picking email infrastructure
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.
Handlebars does not cover idempotency keys, event stream, and webhook coverage, and none of the alternatives below close that gap either. If it is a hard requirement, the shortlist has to widen beyond this category.
