Open developer pathMailSlurp Documentation
Build, test, monitor, and automate real email and SMS workflows
MailSlurp gives developers, QA teams, marketers, and operations teams one platform for messaging infrastructure, release confidence, sender monitoring, and event-driven automation.
Entry points by team
Each path is tuned for the “what do I need to prove or ship?” question that team usually brings to docs.
QA and release teams
Test sign-up, password reset, OTP, and notification flows with deterministic waits, previews, and pass/fail delivery checks.
Open QA pathMarketers and lifecycle teams
Preview live campaigns, audit message quality, and monitor sender posture without replacing your ESP or delivery stack.
Open marketing pathData and operations teams
Capture inbound messages, extract structured data, and route results into downstream systems and operational workflows.
Open operations pathPlatform pillars
Browse by capability when you already know whether you need messaging, testing, monitoring, automation, governance, or API integration guidance.
Messaging
Provision inboxes, domains, phone numbers, and connected mailboxes for production and testing workflows.
Testing and QA
Validate async communication paths with message waits, compatibility checks, rendering previews, and release gates.
Monitoring
Track sender health, DNS drift, and live campaign output after release instead of relying on manual spot checks.
Automation
Route inbound traffic, trigger downstream systems, and transform messages into structured data.
Team and governance
Control environments, access, SSO, storage, and shared team resources before you scale usage.
Developer tooling
Use SDKs, examples, API reference, and protocol access patterns that fit your stack and delivery workflow.
New and notable
Recent additions that change how teams validate sender health, campaign quality, and release readiness.
Campaign Probe
Watch live campaign output through controlled capture addresses and automated checks.
Device previews
Review rendering in the clients and devices your stakeholders actually care about.
Domain Monitor
Track sender-health posture and DNS drift before it becomes a delivery incident.
Email audit
Check links, images, authentication, and content quality in one review pass.
Setup and governance
Plan shared access, environments, and sign-in controls early so production rollout is boring instead of fragile.
Developer resources
Use the reference material and starter assets that shorten time to first working integration.
API reference
Browse every endpoint and generated request model.
SDK libraries
Start in JavaScript, Java, Python, C#, Go, PHP, Ruby, and more.
Examples
Jump into runnable reference projects instead of starting from scratch.
GitHub examples
Production-oriented repositories and starter integrations.
Swagger UI
Explore the REST API with an interactive endpoint browser.
Postman collections
Run common API flows quickly from a shared collection.
