Everything you need to
send transactional email.

One platform for the API, the SMTP relay, delivery events, templates and sender authentication. Pick a product below — both send paths land in the same pipeline with the same logs.

Email API

REST API for modern apps

One authenticated HTTPS request, one message ID back. Typed payloads, idempotent retries and structured delivery events.

  • POST /v1/send over HTTPS
  • Bearer API keys, scoped per environment
  • Idempotency keys for safe retries
  • Same pipeline as SMTP
POST https://api.notifiva.com/v1/send

SMTP Relay

Drop-in for existing apps

Point your framework or CMS at the relay. Standard SMTP, standard ports — no application rewrite. Same logs and webhooks as the API.

  • smtp.notifiva.com
  • Ports 587 (STARTTLS) & 465 (TLS)
  • Easy migration from any provider
  • Unified observability
