MailSlurp
Real-time messaging infrastructure for QA testing, development, and automation.
About MailSlurp
MailSlurp is an all-in-one messaging toolkit that provides real, programmable email accounts and phone numbers for testing, development, and automation. It enables developers and QA teams to generate unlimited unique email addresses and phone numbers on demand, integrate with major programming languages, and use REST APIs, SDKs, IMAP, and SMTP. With features like end-to-end email and SMS testing, OTP/MFA testing, password reset flows, and CI/CD integration, MailSlurp helps teams ensure that their applications handle messaging correctly in real-world scenarios. The platform also offers device previews, inbox placement testing, deliverability monitoring, and AI-powered email parsing to extract structured data. By providing a scalable and reliable infrastructure, MailSlurp supports high-volume messaging workloads, and with AiDOOS, deployment and adoption can be further enhanced through automation, continuous testing, and integration with existing development workflows.
