Split traffic.
Test providers.
Failover fast.
Email Relay lets you route email across providers—without code changes or risky migrations.
Set flexible routing rules based on the signals that matter most—message content, domain, tags, metadata, and more.
Use Relay with our Rule Engine to segment and direct traffic intelligently across multiple delivery paths. Send transactional emails one way and marketing another. Route around outages in real time. Test new IPs. The possibilities are wide open.
Provider issue? No problem.
Relay lets you reroute traffic to a backup provider automatically—before it impacts your users.
When performance and uptime are critical, failover is a must-have. Relay gives you built-in continuity, even across providers.
No need for a risky cutover.
Whether you’re onboarding with SocketLabs or switching from a legacy ESP, Relay supports phased migration without downtime or dual-paying nightmares.
Split traffic. Prove performance. Scale gradually.
A few more highlights to show how Email Relay gives you the control you need—without the complexity…
Direct traffic by content, sender, or signal with precise, rule-based logic.
Run multi-provider, multi-path setups with confidence and control. No hacks required.
Diagnose and optimize delivery across providers, with full visibility at every hop.
Spin up routing logic without dev lift. Configure, test, and deploy with clicks — not commits.
