Create and control real email addresses from code
Provision inboxes for applications, test runs, support queues, and agents. Send messages, wait for received email, inspect links and attachments, and keep each address tied to the workflow that owns it.
Hosted inboxes, connected providers, and custom domains
Use hosted MailSlurp addresses, connect Gmail or Outlook, or create inboxes and aliases on your own domains.
Send, receive, and wait for email from code
Use REST APIs and SDKs to send messages, wait for matching email, and inspect headers, links, and attachments.
Route messages into any workflow
Connect inbound email to webhooks, AI agents, databases, support tools, and automated pipelines.
Provision phone numbers and receive SMS in your workflows
Create phone numbers for OTP, MFA, recovery, alerts, and inbound SMS. Wait for real messages through the API, extract verification codes, and keep phone activity visible across development, CI, and production workflows.
Provision real phone numbers
Create dedicated numbers for tests, applications, support, and long-lived messaging workflows.

Connect SMS to automated workflows
Trigger webhooks, route inbound messages, and keep phone activity attached to tests and applications.
End-to-end testing toolkit.
Test the complete customer journey with real email addresses and phone numbers, then keep every message, code, and assertion attached to the test run that created it.
OTP and MFA journeys
Receive email or SMS codes, submit them in the browser, and assert the verified state across signup, login, and recovery.
Plugins for major frameworks
Use MailSlurp with Playwright, Postman, Selenium, Cypress, Java, Python, JavaScript, and the tools your team already runs.
Integrate into CI/CD
Run deterministic email and SMS checks on every pull request and block a merge when a critical customer flow fails.
Load test real delivery
Provision isolated inbox and phone cohorts, increase concurrency, and measure receipt timing without shared-account collisions.
Email rendering and inspection.
Review the message that actually arrived, see how it renders across providers and devices, and catch content or delivery problems before customers do.
Render on real devices
Preview Gmail, Outlook, Yahoo, Apple Mail, mobile, desktop, light mode, and dark mode from one delivered email.
Check inbox placement
See whether email reaches inbox, promotions, or spam across real Gmail, Outlook, Yahoo, and Apple provider mailboxes.
Monitor sender authentication
Track SPF, DKIM, DMARC, MX records, reputation signals, blocklists, and domain changes before inboxing drifts.
Audit links and content
Catch broken links, missing images, unsupported markup, and content warnings in the email received by your test inbox.
Programmable email and SMS API questions
Create communication identities in code, control their lifecycle, and use the messages they receive in applications and automated tests.
What is a programmable email and SMS API?
A programmable email and SMS API lets software create email addresses and phone numbers, send and receive messages, wait for matching content, and route message events without manual inbox or device access. Explore the API documentation.
Can MailSlurp create real email addresses and phone numbers from code?
Yes. Create hosted inboxes, connected inboxes, custom-domain addresses, and dedicated phone numbers through REST APIs and SDKs, then keep each resource tied to the application, customer, agent, or test run that owns it. See programmable email. See programmable phone numbers.
How do I test OTP and MFA with programmable phone numbers?
Provision or assign a number to the test, submit it in the signup or login flow, wait for the inbound SMS, extract the one-time code, complete the browser journey, and release or retain the number according to the test policy. Test SMS OTP with Playwright. Test SMS OTP with Cypress.
Can I use MailSlurp with Playwright and Cypress?
Yes. Playwright and Cypress tests can create private inboxes or phone numbers, trigger the application flow, wait for the delivered email or SMS, extract a link or code, and assert the final state in the same run. Read the Playwright email testing guide. Read the Cypress email testing guide. Create disposable test inboxes.
