Case Study: SendGrid achieves peak performance and pain‑free deployments with Pantheon

Twilio SendGrid Hits Peak Performance, Pain-Free Deployment with Pantheon

Twilio SendGrid, a cloud‑based email service sending over 30 billion emails a month, needed to modernize its marketing site and free engineering from routine content work. Their in‑house Ruby on Rails site and aging hardware produced unreliable deployments, no stable Dev/Test/Live workflow, and left marketing dependent on engineering, causing slow fixes and operational strain.

SendGrid migrated to WordPress on Pantheon with a Pantheon agency partner, adopting version‑controlled environments, staging, and easy backups. The move delivered immediate performance improvements, predictable, pain‑free deployments, reduced reliance on engineering, and gave marketing the autonomy to launch and iterate campaigns quickly — enabling the company to scale and focus engineering on core product work.
