MJML alternatives
Providers that compete with MJML on at least one of: Templates
Markup language for responsive email.
Switching as teams building autonomous agents
An agent stack treats email as a two-way primitive. Inbound has to arrive as structured JSON a tool call can consume, sends have to be safe to retry when a model loop repeats itself, and every action needs an audit trail. A provider without inbound parsing only solves half the problem.
MJML does not cover inbound parsing, idempotency keys, webhook coverage, event stream, batch sending, SDK breadth, and multi-tenant support. Handlebars, Liquid, and Parcel close that gap. The order below weighs this audience's priorities first, so it differs from a general popularity ranking.
