Why bztalk

Built for messaging at scale in Korea

Six things we got right so you can ship a campaign on day one.

KakaoTalk first

Alimtalk and Brand Message as primary channels with automatic SMS fallback — reach the dominant Korean messaging surface without code branches.

PIPA-compliant by default

All data stays in Seoul (ap-northeast-2). Built-in consent management, audit logging, 90-day PII TTL, and right-to-erasure are wired in — not bolted on.

Smart fallback chain

Push → KakaoTalk → SMS → Email runs automatically — the worker picks the cheapest channel a recipient actually accepts and falls back if it fails.

Multi-provider

Bizppurio, NHN Cloud, Aligo — choose per tenant. Live provider-health monitoring switches off a bad provider before your delivery rate notices.

Developer-friendly API

RESTful API with HMAC-SHA256 auth. Webhook delivery callbacks. A live playground in your console for iterating without leaving the browser.

Real-time analytics

Delivery tracking, channel performance, per-campaign roll-ups, cost analysis — all in the console and exportable as CSV.

How it works

From signup to first send in three steps

No long onboarding. A tenant, a key, a send.

1

Create your tenant

Reach out and we'll spin up your tenant in dev. We provision the providers you picked (Bizppurio / NHN / Aligo / SES / FCM / APNs) and seed your sender numbers.

2

Issue an API key

Sign in to the console, mint a bearer token, and store it in your secrets manager. The raw value is shown once at creation — keys are hashed at rest.

3

Send

Hit POST /v1/messages with a recipient and channel. The worker handles templating, fallback, and webhook callbacks. See deliveries flow in the console within seconds.

Channels

Every surface your customers actually use

One integration, the channels operators rely on across Korea and beyond.
