About Senviok
Senviok is a developer-first messaging infrastructure platform for engineering teams and product companies that need reliable delivery of transactional email, SMS, WhatsApp messages, and OTPs through a single REST API.
Key capabilities include:
- Unified messaging API: Send email, SMS, and WhatsApp with one API key, one wallet, and one log stream, using consistent endpoints such as
/v1/emails,/v1/sms, and/v1/whatsapp. - Durable queueing and retries: Requests are acknowledged in under 20ms and buffered in a durable ingestion queue with automatic retries, exponential backoff with jitter (1s → 4s → 16s + jitter), and dead-letter handling to reduce message loss during provider outages or rate limits.
- Email domain authentication automation: Generates DKIM (triple CNAME), SPF, and DMARC DNS records for sending domains, then monitors DNS propagation to support inbox placement without running mail servers.
- Security and observability: Supports HMAC-SHA256 signed webhooks, live API key rotation from the dashboard, SHA-256 credential hashing, plus an operational status page that publishes metrics like 30-day uptime, ingestion latency, queue depth, and per-region latency.
Available via Web dashboard and REST API (with official Node.js and Python SDKs; usable from any language via HTTP).
Target users include developers, engineering teams, and B2B product companies building authentication, password resets, payment notifications, alerts, and other critical transactional messaging flows.
Notable for African teams, it lists a Lagos regional node and prices plans in Naira (₦) (with USD pricing also available), including a free plan with 3,000 emails/month and no card required, plus a public status console at status.senviok.live for operational transparency.
