Email API

Transactional & marketing email.
Built for African deliverability.

Most email gateways were tuned for North American ISPs. Black Konnect's email service is warmed against African inbox providers, regional anti-spam policies, and the mobile-first reading habits of the audience.

Capabilities

A modern email pipeline tuned for the continent.

From domain warm-up to inbox placement diagnostics — the operational gear most teams build themselves, made first-class.

Domain warm-up

Gradual reputation building.

Automated send-rate ramping for new domains, with per-ISP heatmaps.

DKIM / SPF

Signed at the gateway.

We rotate keys quarterly; you publish one DNS record once.

Templates

MJML-based responsive templates.

Renders crisp on every African Android inbox client.

Analytics

Open, click, bounce, complaint.

Per-recipient telemetry streamed to your webhook.

Compliance

GDPR + POPIA + Kenya DPA aligned.

Subject access requests honoured; data residency options.

Two lines of code

Send your first transactional email in five minutes.

One POST, one templated subject, one body. Variables interpolate from a JSON payload; rendering, MIME assembly, and DKIM signing happen on our side.
