Core offering

SendGrid provides a cloud-based email API and SMTP service for transactional and marketing email delivery at scale. The platform processes over 200 billion emails monthly and offers two core products: the Twilio SendGrid Email API (REST API and SMTP relay for programmatic transactional email) and Marketing Campaigns (drag-and-drop email marketing with contact management, segmentation, and automation). It serves developers, marketing teams, and enterprises globally through self-service API access, SDKs in seven programming languages, and enterprise field sales via Twilio.

Product overview

SendGrid, now part of Twilio, operates as a two-product email platform: the core Twilio SendGrid Email API (transactional email service with SMTP and REST API) delivers emails at scale with proven deliverability handling over 200 billion emails monthly, while Marketing Campaigns provides flexible tools for creating and managing marketing email campaigns with automation, segmentation, and design capabilities. The two products are designed to serve different use cases—transactional versus marketing—while sharing the same infrastructure and account ecosystem.
