Quick start

MailSlurp gives your team real inboxes, phone numbers, testing tools, monitoring workflows, and automation primitives in one platform. Let's see it in action.

1. Create an account and API key

Before you run any workflow:

Create a MailSlurp account.
Generate an API key in developer settings.
Decide whether you want to start with an SDK or direct REST calls.

Sign up: app.mailslurp.com/sign-up
API keys: app.mailslurp.com/settings/developers
SDK libraries: /sdks/
API reference: /api/

Create account

2. Run your first real workflow

Create a fresh inbox for a test, app flow, or operational automation. This is the core MailSlurp pattern: isolate the address, run the workflow, then inspect or wait for the resulting message.

MailSlurp supports JavaScript, Java, C#, PHP, Python, Ruby, and Go SDKs. The same workflows are also available over REST.

Once you have an inbox, your next move is usually one of these:

Send from your app or MailSlurp: /emails/
Wait for a real email or SMS deterministically: /wait-for/
Add production sender identity: /custom-domains/
Provision phone numbers for OTP and SMS flows: /txt-sms/

3. Dive into topics

Messaging

Core inboxes, email, SMS, custom domains, attachments, and external mailbox connectors.

Testing

End-to-end release confidence with waits, device previews, email audit, compatibility checks, and deliverability tests.

Monitoring

Monitor domains, live campaigns, and sender health so issues are visible before customers notice them.

Automation

Use webhooks, forwarding, routing rules, alias proxy, and AI transformers to turn messages into events and data pipelines.

Governance

Share access safely with organizations, custom roles, environment isolation, SAML SSO, and storage controls.

4. Common workflows

Messaging setup and send/receive flows: Inboxes, Emails, Custom domains, TXT/SMS
Test and release confidence: Testing, Wait for methods, Deliverability tests, Device previews
Monitoring and sender health: Monitoring, Domain Monitor, Campaign Probe, Reputation
Automation and downstream routing: Webhooks, Forwarding, Routing rules, AI transformers
