How does it work?

MailSlurp is an email service that lets you send, receive, and test email processes. You can create email addresses in code or using our webapp dashboard. MailSlurp lets you test and verify email content and attachments moving through your system during automated testing and development.

Email in code

Create real email addresses on demand. Send and receive email in Javascript, Ruby, PHP, Python, Java, and more. Built for developers and QA testers to build email functionality and test email related processes.

// install package with `npm install --save mailslurp-client`
import { MailSlurp } from "mailslurp-client"
// instantiate a client with API KEY
const mailslurp = new MailSlurp({ apiKey: 'your-api-key' })
// create an inbox with a random email address ending in @mailslurp.com
const { emailAddress, id } = await mailslurp.createInbox()
expect(emailAddress).toContain("@mailslurp.com")
// for full control over inbox email addresses use a custom domain
const customInbox = await mailslurp.createInbox("test@mydomain.com")
