It's aimed at developers integrating email into applications and marketing teams managing campaigns.

Where to start

Sign up for a SendGrid account, generate an API key, and use it to authenticate requests through the Node.js library or the HTTP API. Start with a single verified sender address before setting up domain authentication for production use.
