Platform Capabilities
A complete suite of transactional email tools engineered for uptime, compliance, and developer productivity.
Drop-in SMTP endpoint with TLS 1.2/1.3 enforced. Authenticate using credentials or certificate-based auth. Compatible with any mail client or framework.
Send transactional messages programmatically via a clean REST API. JSON payloads, versioned endpoints, and official SDKs for Node.js, Python, and Go.
Track message status across every stage — queued, delivered, opened, bounced — from a centralized dashboard with live event streams.
Automatic suppression lists for hard bounces and spam complaints. Intelligent retry logic for soft bounces. Protect your sender reputation proactively.
Request a dedicated sending IP for complete control over your sender reputation. Ideal for high-volume enterprise applications with consistent sending patterns.
Receive real-time delivery event notifications via HTTPS webhooks. Filter by event type, retry on failure, and validate payloads with HMAC signatures.
Full support for email authentication standards. We guide you through DNS configuration and validate your records to prevent spoofing and improve deliverability.
Built around CAN-SPAM, GDPR, and industry best practices from day one. Our infrastructure enforces policy-level restrictions on sending behavior — not just guidelines.
Integration & Workflow
CloudRelay is designed for rapid integration. Whether you prefer SMTP or API-first workflows, you'll be sending transactional emails in your first session.
Point your application at our SMTP endpoint or call our REST API using your API key. No complex setup. We provide implementation guides for all major languages and frameworks.
Send account verifications, password resets, billing receipts, and security alerts directly from your application logic. All outbound traffic is validated for compliance before delivery.
Access your delivery dashboard to track message status, review bounce and complaint rates, and export logs. Set threshold alerts to stay ahead of deliverability issues.
Our system continuously audits outbound traffic for policy violations. Accounts with anomalous sending patterns are automatically flagged for review, protecting the shared sending infrastructure.

Every component of the CloudRelay infrastructure is designed, operated, and audited with legal and regulatory compliance as the primary design constraint.

About CloudRelay LLC
CloudRelay LLC was founded in 2024 in Austin, Texas, with a single mission: to provide businesses with a secure, reliable, and rigorously compliant transactional email infrastructure they can build upon with confidence.
We recognized a gap in the market for an email relay provider that treats compliance as a non-negotiable architectural principle rather than an afterthought. Every policy, every technical control, and every operational decision at CloudRelay is made through the lens of protecting our customers, their end users, and the integrity of the broader email ecosystem.
Our platform is designed exclusively for transactional messaging — the emails that users rely on to access their accounts, receive their orders, and stay informed about activity that directly affects them. We do not support, and will never support, bulk marketing or unsolicited commercial email.
