Trusted by top companies worldwide
Email and mobile platform to power testing, development, automation, and delivery management.
Test email and SMS end-to-end. Validate critical paths such as sign-up, password reset, MFA, invite codes, and SMS notifications. Connect MailSlurp APIs and SDKs to major test frameworks, then use purpose-built test functions to keep checks reliable as your suite grows.
Create unlimited real email accounts and phone numbers. Connect your systems through APIs and SDKs to send and receive email and SMS at scale. Add automations and AI transformers to label, extract, and respond. Keep messages moving with resilient webhooks and queue-based infrastructure.
Review and verify email campaigns across supported render targets and provider contexts. Audit content for broken links, missing images, and faulty templates. Catch regressions before important campaigns. Configure continuous monitoring and alerts for domain and email health.
Measure inbox placement across major providers before sending to customers. Detect spam filtering, throttling, and domain reputation issues early with controlled test runs. Automate warm-up workflows to build sender reputation over time and maintain consistent delivery performance at scale.
Isolate messaging resources across development, staging, and production with strict environment boundaries. Enforce role-based access controls, manage teams centrally with SAML SSO, and prevent cross-environment data leakage. Maintain full audit trails of access and activity while enabling teams to operate independently at scale.
