Simple pricing. Clear usage.
SMS automation
REST endpoints, JWT and API-key auth, idempotent sends, and delivery tracked in real time.
Developer-first SMS API
REST endpoints authenticated with JWT or SA-branded API keys. Send single messages or bulk, with idempotent retries and a unified response envelope.
Campaigns & contact lists
Upload a contact list or sync Google Contacts, then schedule a campaign. A dedicated worker polls every 30s and sends in chunks of 500 with per-recipient credit accounting.
Tanzania phone validation
Numbers normalize to E.164 +255 and must be mobile — landline ranges are rejected. SMS parts are counted via GSM-7 / UCS-2 so the bill always matches.
Real-time delivery tracking
Every send lands in your message log with live status — sent, delivered, failed, or rejected — updated from real-time delivery reports.
Exact credit billing
1 credit = 1 SMS part. The append-only ledger is atomic and idempotent, so retries never double-charge. Track every deduction and top-up.
Mobile money top-ups
Buy credits with Tanzania mobile money through Snippe, or go manual for bank transfers. Pay-as-you-go with a tiered TZS-per-credit rate.
Custom Sender IDs
Register and manage your own branded alphanumeric Sender ID through our gateway partners. Submit documents, set a purpose, and track approval status live.
Google Contacts sync
One-way import of every Tanzania mobile number from your Google Contacts into a dedicated list. Connect once, sync on demand.
The beliefs behind SendAfrica
SendAfrica exists so teams can send SMS confidently across African mobile networks.
Reliability, by design
Every message has an idempotency key, every credit mutation is atomic, and campaign state is locked before a worker picks it up. Retries never double-send or double-charge.
SMS-AUTOMATION, built right
Numbers validate to E.164 +255, mobile prefixes only, and SMS parts count via GSM-7 / UCS-2 so the bill always matches the API response.
Transparency you can audit
The credit ledger is append-only and every action — sends, top-ups, grants — is a single row. Delivery arrives from mobile networks and is deduplicated before it is logged.
Pay as you send, no subscriptions
1 credit = 1 SMS part. Plans set your rate limit — Free 60, Pro 600, Enterprise 6,000 requests per minute.
