SMTP Relay & API

Integrate transactional email sending directly into your application via secure REST APIs or traditional SMTP TLS connections.

Event Webhooks

Receive real-time POST payloads to your endpoints for critical delivery events, including hard bounces, soft bounces, and spam complaints.

Domain Authentication

Strict enforcement of SPF, DKIM, and DMARC alignment. We do not allow sending from unverified domains to maintain IP reputation.

How Our Infrastructure Routes Traffic

Step 01

REST API Trigger

Your backend fires a payload containing envelope & body attributes.

Step 02

Isolation Queue

Transactions are parsed and separated based on sender authentication status.

Step 03

Routing MTA

Our relays dispatch directly using clean, domain-aligned IP pools with TLS forced.

Step 04

Webhook Loop

Designed for transactional messaging workflows.
