SendGrid Transactional Email
A media-monitoring / data-orchestration platform
Overview
A minimal Node.js build validating transactional email delivery through the SendGrid API, intended to de-risk the platform’s outbound email (subscription digests and notifications) before wider integration.
Why It Exists
The platform delivers media-monitoring results to subscribers by email, so the team needed to confirm SendGrid’s API, sender authentication, and delivery flow worked end to end before wiring it into the production services. A tiny standalone build is the fastest way to verify provider behavior and credentials.
What We Built
A single-purpose Node.js script (send-email.js) using the official @sendgrid/mail SDK with dotenv-based configuration for API key, verified sender, and recipient. The README documents the SendGrid setup path including the mandatory sender-identity/domain verification step. It is intentionally small, one dependency for mail, one for config.
Technologies & Approach
Node.js with the @sendgrid/mail client and dotenv for secrets. Kept deliberately minimal so the only variable under test is SendGrid’s API and sender-verification behavior.
Outcome / Impact
Validated SendGrid as a viable transactional-email provider for the platform and documented the sender-verification requirements, informing the production email-delivery path handled by the broader services.
Capabilities Demonstrated
- Rapidly validating third-party email providers with focused builds
- Integrating SendGrid transactional email in Node.js
- Documenting provider setup and sender-authentication requirements
