- SendGrid, Inc. (SEND) operates as a leading cloud-based communications platform specializing in transactional and marketing email delivery services for businesses worldwide. Founded in 2009 and headquartered in Denver, Colorado, the company, now a subsidiary of Twilio Inc. following its $2 billion acquisition in February 2019, offers a comprehensive suite of products including its proprietary Email API for scalable transactional emails such as shipping notifications, sign-up confirmations, and password resets; Marketing Campaigns for automated email newsletters, drag-and-drop design tools, signup forms, and segmentation; Email Validation API to enhance deliverability; SMTP relay services; and advanced analytics for tracking opens, clicks, bounces, unsubscribes, and spam reports, supported by ISP monitoring, SPF, DKIM, and feedback loops. SendGrid serves small- to medium-sized businesses and enterprises across industries like e-commerce, SaaS, and digital communications, with global operations delivering over 148 billion emails monthly at a median speed of 1.9 seconds and 99% deliverability. The platform integrates seamlessly with developer tools and provides tiered subscription plans such as Essentials, Pro, and Premier, previously including a freemium model.
In recent developments, SendGrid retired its free Email API and Marketing Campaigns plans effective May 28, 2025, following a 60-day transition period to encourage upgrades to paid tiers, reflecting a strategic shift toward monetizing higher-value usage amid record volumes like 12 billion emails on Black Friday 2024. The company has enhanced fraud prevention, reducing phishing and account takeover incidents by over 50% since December 2024 through AI and human intelligence, blocking 200 million phishing emails monthly. Additionally, SendGrid issued its 2025 Email Deliverability Guide with updated best practices and deprecated email-to-SMS gateways for commercial use in July 2024 to comply with policies and improve platform integrity. These changes underscore ongoing operational refinements under Twilio's ownership to support scalable, secure customer engagement.
