Dugble provides APIs for transactional email and SMS, with additional messaging workflows for audiences, broadcasts, domains, sender identities, and delivery tracking.

Email

Send transactional email, schedule delivery, attach files, and inspect message events.

SMS

Send SMS, manage sender IDs, schedule messages, and track carrier outcomes.

Sender domains

Authenticate the domains used for outbound email with DKIM and SPF.

API Reference

Explore request fields, responses, errors, and endpoint-level behavior.

​
Start with a server-to-server integration

Dugble authenticates public API requests with team tokens. Keep tokens on your server and grant only the permissions your integration needs.

Quickstart

Send your first transactional email and retrieve its delivery state.

Authentication

Learn how team tokens, permissions, rotation, and revocation work.

​
Asynchronous delivery

Email and SMS send requests are accepted asynchronously. A successful 202 Accepted response means Dugble queued the message for delivery; it does not mean the recipient has received it yet. Use message retrieval, delivery events, and supported webhook workflows to observe what happens after acceptance.
