Disposable inboxes
Unique test data
Create unique email addresses per run to keep identities isolated and repeatable.
Bring real inbox assertions into Testim automation
MailSlurp provides disposable inboxes and API-first email assertions so Testim teams can validate sign-up, password reset, and notification workflows end-to-end.
Works with your QA stack
Trusted by teams at
Used by engineering, QA, lifecycle, and operations teams building and testing email and SMS workflows.
API-first
Custom actions
Call MailSlurp from Testim steps to wait for emails and parse links or codes.
Full payload
Evidence on failure
Capture the message body, headers, and metadata so failures are easy to debug.
Enterprise-ready
Scale QA
Upgrade for more volume, retention controls, and team access as coverage grows.
Core capabilities
Testim integration capabilities teams can act on
Provision inboxes per scenario
Generate a disposable inbox for each flow so verification emails are always routed to the right test identity.
- Disposable inboxes
- Unique identities
- Repeatable runs
Wait for email and extract codes or links
Trigger a workflow email, wait for the right message, and extract OTP codes, links, or tokens for the next step.
- OTP codes
- Magic links
- Password reset
Use the REST API from Testim custom actions
Integrate quickly using API calls in custom steps to fetch messages and assert on payload content.
- REST API
- SDKs
- Fast setup
Reduce flakiness and speed up root cause analysis
Avoid shared mailboxes and non-deterministic timing. Store evidence so failures are actionable.
- Deterministic
- Debuggable
- CI-friendly
Team use cases
Ways teams use MailSlurp for Testim integration
QA teams
Account verification and onboarding flows
Validate the full sign-up journey by capturing verification emails and completing the flow inside your tests.
- Capture verification links and OTP codes
- Remove reliance on shared mailboxes
- Catch regressions before release
Release programs
Notification and alert regression gates
Gate releases on real email outputs for password reset, invoices, and critical product messaging.
- Detect broken templates early
- Shorten incident response time
- Improve release confidence with evidence
Platform teams
Standardize email assertions across squads
Offer a repeatable inbox provisioning pattern so multiple teams can scale QA consistently.
- Create reusable custom action patterns
- Reduce test glue duplication
- Scale volume and team access over time
Start testing
Start previewing customer emails quickly
Day 1
Add a disposable inbox to one Testim flow
Start with a high-signal workflow and validate receipt plus one assertion to prove value quickly.
- Create an inbox for the test identity
- Trigger one workflow email
- Wait for the email and extract the expected code or link
Week 1
Add reusable custom actions for email assertions
Turn the pattern into a repeatable building block for onboarding, resets, and notifications.
- Create custom steps to provision inboxes and wait for emails
- Store evidence (payloads) when assertions fail
- Expand to two more critical workflows
Week 2+
Scale and harden the process
Upgrade when you need more volume, retention, and team workflows for enterprise programs.
- Adopt consistent patterns across squads
- Set ownership for workflow failures
- Upgrade for higher scale and shared team workflows
Customer use cases
Where MailSlurp helps
Enterprise QA teams
Challenge: Email workflows are often excluded from automation because mailbox access is brittle and hard to debug.
What improves: Add deterministic email assertions using disposable inboxes and clear evidence.
Teams with multiple environments
Challenge: Staging and production flows drift and regressions are caught late without reliable checks.
What improves: Run the same inbox assertions across environments with predictable test data.
Release stakeholders
Challenge: Manual email validation does not scale with release cadence and creates incident risk.
What improves: Gate releases on evidence-backed email assertions.
Better email releases
What gets easier before send time
Lower flake rate
Use disposable inboxes instead of shared mailboxes and timing sleeps.
Actionable evidence
Capture message payloads, metadata, and links so failures are diagnosable.
Fast integration
Use REST APIs and SDKs from custom actions without changing your app mail stack.
Enterprise scale path
Upgrade for higher volume, retention, and team access when adoption grows.

FAQ
Common questions before starting
Do we need a dedicated plugin for Testim?
No. Many teams use custom actions and API calls to provision inboxes, wait for emails, and extract codes or links.
Can we test password reset and verification emails?
Yes. These are the most common flows: signup verification, password reset, and MFA email steps.
Can we capture full email payload evidence?
Yes. You can fetch HTML/text bodies, headers, and metadata to make failures easy to diagnose.
Is this suitable for enterprise programs?
Yes. Start free and upgrade for higher volume, retention, and team workflows as your coverage scales.
