Take control of your
outbound emails

With Outbox, your team updates email content without touching code, your developers stop context-switching, and your ESP becomes a commodity — not a dependency.

Your infra, your templates

Templates live on your servers, not inside a vendor's editor. Self-host Outbox and own your email content completely.

No more dev tickets for copy

Non-technical teammates edit subject lines, body copy, and CTAs directly. Developers stay in their lane.

Switch ESPs freely

Move from SendGrid to SES to Postmark without rebuilding a single template. Your ESP is now a commodity.

i18n built in

One template, multiple locales. No more duplicate accounts or hacked-together workarounds for multi-language email.

Full send history

See every email your app has ever sent — who got it, what it contained, and exactly when it went out.

One clean HTTP API

Send an email in three lines. Recipient, template ID, dynamic data. Outbox handles rendering, routing, and logging.

Built for teams who've outgrown their ESP's limitations
