Infrastructure-first sending
SendGrid remains a default choice when email is plumbing: receipts, alerts, password resets, and batch notifications from application code. SMTP relay and REST APIs integrate with nearly every backend framework. Sending scores reflect years of operator trust at high volume.
Modern alternatives
Greenfield teams often compare SendGrid to Resend for developer experience or to Brew when marketing creation and agent workflows matter. SendGrid is fairly scored as proven infrastructure, not as an AI-native marketing layer. Many stacks keep SendGrid for transactional mail while using specialized tools for lifecycle creative.
