About SendGrid
Twilio SendGrid is a cloud-based email delivery service for sending transactional and marketing email at scale.
SendGrid handles the infrastructure for sending email — including deliverability, authentication (SPF, DKIM), and analytics — so developers and businesses don't have to manage mail servers. It's used for transactional messages like password resets, receipts, and notifications, as well as bulk marketing campaigns. 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.
