Disposable inbox control

Give every run its own clean mailbox state

MailSlurp disposable inboxes combine fresh mailbox provisioning, deterministic waits, parsing helpers, and automatic cleanup so test traffic never collides.

Create one inbox per run, worker, or user journey

Provision a private mailbox for each CI job or test flow so signup, reset, OTP, and notification checks do not share state.

Match on the message that matters

Filter waits by sender, subject, unread state, and attachment-related conditions so tests stop on the exact email they were written to validate.

Extract links, codes, headers, and attachment details

Pull the verification link, OTP code, metadata, or file indicators needed for assertions without writing custom parsing logic first.

Expire and retire inboxes automatically

Apply short mailbox lifetimes and cleanup policies so disposable test identities disappear after the run instead of becoming a long-lived inbox fleet.

Key workflows

Public temp-mail sites and reused inboxes create collisions, data leakage, and weak assertions. Private disposable inboxes give every run clean ownership and deterministic wait logic.

Workflow 01

Create a fresh inbox, capture the message, and assert the result

Use one private inbox per run so signup, reset, and notification tests can wait for the exact message they need without collisions or shared-state failures.
