Product features
Use the MailSlurp features that make the workflow work reliably in production, not just in a quick demo.
SMS value comes from controlling real phone-number behavior and message receipt under API access, not from a generic messaging claim.
Most teams start with SMS because they need reliable verification, OTP, and auth messages, not generic bulk messaging.
Teams should be able to run SMS, email, and testing workflows together instead of stitching together disconnected tools.
Spin up regional numbers for OTP, account verification, and messaging workflows with API control.
Validate code delivery, extraction, retries, and user journey behavior with real numbers under API control.
Provision numbers, receive messages, and integrate SMS into signup, recovery, and operational workflows.
Test journeys that span both channels without splitting tooling or saved results across different systems.
Developer integration
Provision numbers, receive SMS, and validate mobile verification flows with SDKs, webhooks, and deterministic wait helpers.
Start with auth-critical SMS
Validate one OTP or verification journey end to end, then expand into broader SMS and cross-channel workflows once the setup is working reliably.
