What you can build

  • Code an adapter that takes your application’s event records, maps them to the data you intend to send, and submits the result through Dittofeed’s API.
  • Build a repository checker that reads MJML email templates and reports missing organization-required footer text or unresolved placeholders before a change is reviewed.
  • Create test cases from sample users and events, use Dittofeed’s testing SDK in CI, and turn campaign test outcomes into a concise pass/fail report.
  • Build a Git change summarizer that takes a messaging-campaign branch diff and produces a reviewer-ready list of changed templates and campaign resources.
  • Code a generator that combines approved locale-specific text with MJML templates and writes separate localized template files for review in Git.

Try this prompt

Build a small end-to-end event adapter for Dittofeed. Take representative event records from a clearly documented input format, map them into the customer and event data your application needs to send, and submit them through Dittofeed’s API. Add tests using sample records, report invalid or unmapped data without silently dropping it, and preserve the original input for diagnosis. Keep credentials out of source control and document the adapter’s assumptions and setup.

Get started

  1. Choose a deployment route

    Use the self-hosted Docker Compose walkthrough linked from the README, or follow its self-hosted Render documentation.

  2. Plan data and messaging services

    The README describes connecting data through Segment, Reverse ETL, or the Dittofeed API, and using major email providers such as SendGrid or Amazon SES.

  3. Explore local development

    For running Dittofeed locally and contributing, follow the contributing documentation linked from the README.

License & notes

MITThe repository is MIT-licensed; include the MIT notice when distributing copies. Self-hosting requires infrastructure, and sending messages may incur costs from email, SMS, push, or other providers. The README also identifies closed-source, separately licensed features—including multi-tenancy, embedding, and white-labeling—which are not covered by the repository’s MIT license. No dollar amounts are quoted.

  • Self-hosting still requires infrastructure, and message delivery may require separately billed providers.
  • Embedding, multi-tenancy, and white-labeling are identified as features in a separately licensed closed-source codebase.
  • The README describes campaign testing and Git workflows, but does not specify their interfaces or file formats; verify those details in the linked documentation before building against them.
