Every email tool — Loops, Customer.io, Braze — needs setup: instrument events, build segments, write templates. Weeks of setup. Everyone still gets the same email. Hermes uses data you already have. Connect your Postgres (read-only, no schema changes), and Hermes generates a unique email for every user based on real behavior — exactly when it matters. No segments. No templates. No setup. Your data already knows who’s about to churn. Hermes turns that into insight and acts on it.
