Twilio SendGrid provides email delivery infrastructure and marketing tools for businesses that need to send transactional and promotional messages. Its services include an Email API for application-generated mail and campaign features for marketing teams, with tools for sender authentication, contact management, and delivery monitoring. Developers can integrate email sending into products, while marketers can plan and manage campaigns through the platform. SendGrid is a technology provider, not a traditional email agency, and the listing should distinguish its software from managed campaign services.
