EMAIL DELIVERY

One platform.
Two ways to send.

Use SMTP for instant compatibility or integrate the Email API for deeper control. Both routes share the same delivery engine, suppression layer and event stream.

SMTP RELAY

Connect once.
Send with confidence.

  • Use standard SMTP credentials
  • Route traffic by recipient provider
  • Protect reputation with suppression checks
  • Monitor every recipient outcome

in minutes.

VuelaMail keeps the integration surface small. Authenticate your domain, create a credential and send. Routing, provider throttling, bounce handling and retries run behind the same interface.

{ }

Email API

A focused JSON API for transactional and campaign sends with clear acceptance results.

  • Single and batch submission
  • Metadata and custom headers
  • Idempotent request handling

Stream delivery, bounce, complaint and unsubscribe events back to your application.

  • Signed event payloads
  • Replay-safe processing

Reliable by
default.

Every accepted request enters a durable queue. Temporary provider responses are retried with backoff; permanent recipient failures are classified and suppressed.

DURABLE QUEUE

Restarts do not erase work.

Queued recipients and progress checkpoints survive service restarts and infrastructure maintenance.

state: queued → accepted → delivered
DELIVERY POLICY

Every provider is different.

Domain-specific rate limits and retry schedules keep one provider from slowing the whole campaign.

route: provider-aware / adaptive
SUPPRESSION

Bad addresses stop once.

Hard bounces, complaints and unsubscribes are removed before future sends reach the delivery queue.

suppression: global / immediate
VISIBILITY

Know what happened.

Recipient-level outcomes keep accepted, delivered, deferred and failed states separate.

events: signed / replay-safe
