One API call,
delivered across four channels

Send Email, PUSH, SMS/LMS, and KakaoTalk alerts from a single platform. Built on a platform architecture, so even a company with multiple departments can send independently per project through a RESTful API.

ARCHITECTURE

Architecture & Data Flow

Runs in three stages: request, queue, send. Per-project API requests are queued by channel, processed in order, and results are returned as a report.

01

Request

Each department or project requests a send via the RESTful API. Auth and send history are kept separate per project.

02

Queue & Distribute

Requests are queued per channel and processed in order, controlling send order and pace even under heavy load.

03

Send & Report

Sends go out via Email, PUSH, SMS, or KakaoTalk, with results returned as a report. Failed deliveries are automatically retried.
