About

One of the largest and most established cloud email delivery platforms globally, now integrated into Twilio's communications ecosystem

SendGrid is a cloud-based email marketing and transactional email platform, now operating as part of Twilio, that helps businesses and developers send, receive, and manage emails at scale. It provides tools for email creation, template management, scheduling, delivery optimization, analytics, and API integration to help businesses engage their audiences effectively. Within its Marketing Campaigns product, Twilio SendGrid has expanded into advertising through SendGrid Ads, which enables marketers to extend their existing email campaigns into display and social ad campaigns — including on Facebook, Instagram, and Google Display Ads — from within the same platform. This capability allows marketers to use email data to target current contacts or find new ones, orchestrate outreach across channels, and measure cross-channel campaign impact through advanced analytics. Pricing for the Ads offering is structured as media cost plus a monthly fee and a percentage of media spend above a threshold.
