SendGrid
FreemiumTwilio-owned email delivery platform for transactional and marketing emails with APIs, SMTP relay, templates, and deliverability analytics at scale.
What does this tool do?
SendGrid is a dedicated email delivery platform owned by Twilio that serves both developers and marketers. For developers, it provides a robust Email API with SMTP relay, webhooks for event tracking, and support for multiple programming languages (Node, Python, PHP, Ruby, Go, Java, C#). For marketers, it offers a campaign management suite with email automation, drag-and-drop design tools, A/B testing, and subscriber management. The platform emphasizes deliverability at scale, offering real-time analytics, email validation APIs to reduce bounces, and dynamic templating. SendGrid handles the infrastructure complexity of email delivery—authentication, bounce handling, list management—so organizations can focus on content rather than the technical backend.
