A transactional email API that just works.

Dependal is a developer-first email API focused on deliverability hygiene: suppressions, sensible retries, and clear event logs.

Built as a modern transactional email API for startups, SaaS platforms, and production systems.

Get Started How it works
Dependal

Built for developers — designed for deliverability.

  • Send via API

    Clean endpoints for transactional email with message IDs, tags, and predictable responses.

  • Suppressions built-in

    Hard bounces and complaints are suppressed by default to protect deliverability (rules/TTL coming soon).

  • Event tracking (beta)

    Track sends, bounces, complaints, unsubscribes, and more with structured logs (webhooks coming soon).

Deliverability hygiene, without the drama

Dependal focuses on the boring-but-critical bits: suppression rules, retries, and visibility.
So your product emails stay reliable.

Visibility

Clear logs per message ID

Every send can be traced end-to-end, so “did it send?” becomes a quick answer, not a support ticket.

Protection

Suppression hygiene by default

Hard bounces and complaints are suppressed automatically to protect deliverability from day one.

Developer-first

Simple integration

Clean auth, clear errors, and predictable semantics—so email doesn’t become a multi-week project.

...
Production-minded
Our Story

Email infrastructure, without the chaos.

Dependal is built around what teams hit in production: retries, bounces, complaints, suppression rules, and “what happened to this email?” questions.
