Why SendByte

Built for African products, not adapted for them.

Global providers bill in dollars and host far from your users. Local options are mostly no-code dashboards or single-purpose add-ons. SendByte is one platform, built end to end for how African teams send: fixed Naira pricing, in-region infrastructure, and deliverability you can measure. Everything below is email, live in production today, and the foundation the next channels build on.

Fixed Naira pricing

Billed via Paystack or Flutterwave on your normal card. We absorb the FX, so the price you see is the price next quarter.

What you pay

The dollar, same period

Illustrative. The point: your line stays flat.

SPF, DKIM, and DMARC, handled for you

Authentication and suppression on by default, with per-domain reputation tuned for African networks.

Hosted in Africa, so your packets stay on the continent

In-region processing with NDPR and data residency built into the core, ready for fintech procurement.

Typed SDKs, a real sandbox, and an MCP server

Signed webhooks, idempotent sends, one error shape, and a first send in under five minutes.

Deliverability you can see, not just promise.

We run seed inboxes at the providers your users actually use and measure where your mail lands, then show it in your dashboard. Not a marketing number. A measurement you can check.

Per-domain reputation, SPF, DKIM, DMARC, and a branded Return-Path are set up for you. New domains warm up over their first weeks, and the panel shows the real status the whole way.

Verified

Send

One POST request. The API answers in under 100ms; delivery is asynchronous and traceable.

await sendbyte.emails.send({…});

Delivered

One API call. Typed SDKs. A real sandbox.

Every event is a signed webhook. Every error tells you how to fix it. Every send is safely retryable.

Signed webhooks: All 9 lifecycle events, HMAC-signed and replayable from the dashboard.
One error shape: Every error says what happened, how to fix it, and links its own docs page.
Safe retries: Idempotency keys on the send endpoint. Retry freely; the same key sends once.
A real sandbox: Full API parity and visible logs, with no domain and no real delivery.

// Retry as often as you need.
// Same key, exactly one send.

One error shape and one webhook contract, everywhere.

The boring parts, done right.

Webhooks, logs, idempotency, and retries. The rest of what serious email infrastructure needs, on by default.

Know what happened after the inbox.

Turn on open and click tracking per project, and every open and every clicked link becomes a number you can read, not a guess.

On the email: Opens and clicks sit on each email's timeline, right next to delivery.
As webhooks: email.opened and email.clicked, HMAC-signed like every other event.
On your domain: Served from t.sendbyte.africa by default, or bring a custom tracking domain.

Off by default. You decide per project, and OTP or receipt sends can stay untracked.

Frequently asked questions

What is SendByte?

SendByte is the communications API for Africa. One API and one dashboard send the messages your product depends on. Transactional email is live in production today: receipts, one-time passcodes, password resets, and alerts, with deliverability tuned for the region. Marketing email, SMS, and WhatsApp are in build and open for early access.

Which channels can I use today, and what is coming?

Transactional email is live and in production now. Marketing email, SMS, and WhatsApp are being built to run on the same API, the same dashboard, and the same bill. Request early access to any of them and we bring you in as each channel opens.

How is SendByte different from Resend or SendGrid?

Pricing is fixed in Naira, so exchange-rate swings are our problem, not yours. Infrastructure runs in African regions for lower latency, deliverability tooling like inbox-placement checks and a domain audit is built in, and the same API is growing to cover SMS and WhatsApp so you are not stitching three vendors together.

How quickly can I send my first email?

Under five minutes. Sign up, copy your sandbox key, and send with a single API call. You do not need to set up a domain to start in sandbox mode.

Which languages and SDKs do you support?

A REST API plus official SDKs for Node.js, Python, PHP, and Go, with Ruby on the public roadmap. Anything that can make an HTTPS request can use SendByte, each SDK ships with webhook signature verification, and the same SDKs will carry the new channels as they land.

Do I need a verified domain to start?

No. Sandbox sending works immediately with a test key, with full logs and no real delivery. A verified domain with SPF and DKIM is required only for live sending, and we generate the exact DNS records for you.

How much does it cost?

Email has a free tier with 3,000 emails a month and no card required. Paid plans start at 2,000 Naira a month, and pay-as-you-go is 300 Naira per 1,000 emails. Marketing, SMS, and WhatsApp will be priced in Naira the same way when each opens.
