Welcome to SendByte, the transactional email API built for Africa. Whether you’re sending OTPs, receipts, notifications, or alerts, SendByte gives you a clean REST API, infrastructure hosted on the continent, and pricing in Naira so there are no surprises on your bill.

Send your first email

Install the SDK for your language:
Then drop in your sandbox key and send. Sandbox keys (sk_test_) simulate the whole pipeline, so no domain setup is required:
Your sandbox key is created the moment you sign up and shown once, so copy it. The email then appears in the dashboard with a full event timeline. Building in Go? See the Go SDK.

Full quickstart

The same flow step by step, watching events in the dashboard, and how to go live.

Go live

Verify your sending domain with three DNS records, then swap your test key for a live one.
