},

});REST API, SMTP relay, contact management, deliverability tools — one platform.
POST /api/v1/emails for code integrations or smtp.xipler.com:465 for tools like Supabase Auth and WordPress.
One account, many verified sender domains. DKIM, SPF, MAIL FROM and DMARC records auto-generated per domain.
Enterprise-grade deliverability. Per-domain DKIM signing keeps reputation isolated between projects.
Safe retries with idempotency keys. Zod-validated payloads. Test mode keys never actually send.
Open/click tracking, bounce alerts, suppression lists, real-time webhooks for every event.
Upsert contacts with tags via API. Trigger automations on tag changes. Marketing-ready out of the box.
One project. One API key. Many sender domains. Add a customer's domain via API, share the DNS records, and start sending from their identity within minutes.
