The email platform
built for SaaS
Our marketing team couldn't touch emails without dev tickets. We couldn't tell which transactional email failed or why. Nothing fit — so we built it.
3,000 emails/month free. No credit card required.

Everything you need to send emails from your SaaS. Nothing you don't.
- 01 Integrate
Clean REST API + SMTP
Send your first email with a single API call. Or swap your SMTP credentials and keep your existing setup — no code changes needed.
- 02 Install
SDKs for every language
First-class Laravel package with one-command install. Official SDKs for PHP, Node.js, Go, Java, and Rust — all typed and documented.
- 03 Authenticate
SPF, DKIM, DMARC
Step-by-step DNS wizard walks you through authentication in minutes. Custom tracking domains included on every plan — no CNAME guesswork.
- 04 Send
One domain, one reputation
Stop splitting transactional and marketing across two vendors. One sending domain, one deliverability reputation, one place to monitor it all.
- 05 React
Webhooks for every event
Get notified the moment an email is delivered, opened, clicked, or bounced. Build automations, sync with your database, or trigger in-app flows.
- 06 Debug
Searchable logs
Full-text search across every email you have sent. Filter by recipient, status, or tag. Find exactly why that one email bounced — in seconds, not hours.
