Disposable inboxes
Unique identities
Generate unique email addresses per scenario so test runs remain isolated and reliable.
Automate email verification flows with disposable inboxes
MailSlurp provides disposable inboxes and API-first assertions so AccelQ teams can validate account verification and notification workflows end-to-end with clear evidence.
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 steps
Call MailSlurp APIs to wait for messages and parse links or OTP codes deterministically.
Evidence
Debuggable failures
Fetch payloads and metadata to make failures actionable for engineering teams.
Scale
Enterprise ready
Upgrade for higher volume, retention, and team workflows as adoption grows.
Core capabilities
What teams need when email workflows matter
Create inboxes per workflow and environment
Provision disposable inboxes for staging and production checks so routing is predictable and test data is clean.
- Disposable inboxes
- Environment isolation
- Predictable routing
Wait for matching emails and extract codes or links
Trigger a workflow email, wait for the right message, and extract the data needed to continue the test flow.
- OTP codes
- Magic links
- Password reset
Integrate quickly using REST APIs and SDKs
Use API calls from custom steps to fetch inbox messages and perform assertions without mailbox hacks.
- REST API
- SDKs
- Fast setup
Reduce flakiness and shorten incident response
Make email flows testable with deterministic waits and full payload evidence when failures occur.
- Deterministic
- Evidence
- Reliable gates
Team use cases
How engineering, QA, and operations teams use MailSlurp
QA automation teams
Signup verification and onboarding checks
Validate that verification emails arrive and contain correct links, codes, and template content.
- Capture verification links and OTP codes
- Avoid shared mailbox contention
- Catch regressions earlier in the release cycle
Enterprise programs
Notification regression gates
Turn high-risk workflows into gated checks that ship with evidence and ownership.
- Detect broken templates and links before customers
- Create actionable failure evidence
- Improve release confidence and auditability
Platform teams
Reusable email assertions across squads
Standardize mailbox provisioning and wait patterns so multiple teams can scale QA reliably.
- Reduce duplication in test glue
- Enable parallel execution patterns
- Scale controls and retention as adoption grows
Getting started
Get this working quickly, then build on it
Day 1
Pilot one email assertion in a critical workflow
Prove value by validating email receipt and one key assertion in your highest-impact flow.
- Provision a disposable inbox for the test identity
- Trigger one workflow email
- Wait for the message and extract the expected link or code
Week 1
Turn it into a reusable pattern
Create repeatable custom steps and expand coverage to additional workflows.
- Create custom steps for inbox provisioning and waits
- Store payload evidence on failures
- Expand to password reset and MFA coverage
Week 2+
Scale and standardize the process
Upgrade when you need more volume, retention, and team workflows for enterprise programs.
- Standardize patterns across teams
- Define ownership for workflow failures
- Upgrade for higher scale and shared team workflows
Team fit
How different teams get value
QA teams with release pressure
Challenge: Email workflows are often excluded from automation and regressions are caught late.
What improves: Add deterministic inbox checks with evidence so releases ship confidently.
Teams with multiple environments
Challenge: Routing drift and template changes break flows between staging and production.
What improves: Use disposable inboxes and repeatable assertions across environments.
Enterprise stakeholders
Challenge: Incidents happen when critical messaging workflows are not validated and owned.
What improves: Gate releases on evidence-backed email workflow checks.
Customer outcomes
What gets better once MailSlurp is in place
Reliable, repeatable tests
Use disposable inboxes to eliminate shared mailbox collisions and timing sleeps.
Actionable debugging
Fetch payload evidence to shorten time-to-diagnosis when tests fail.
Fast integration
Use REST APIs and SDKs from custom steps without changing your mail stack.
Enterprise scale path
Upgrade for volume, retention, and team access as coverage expands.

FAQ
Questions people ask before they start
How does this integrate with AccelQ?
Many teams use custom steps to call MailSlurp APIs to provision inboxes, wait for emails, and extract the values needed for the next step.
Can we test account verification and password reset?
Yes. Capture verification links, OTP codes, and reset links and validate the full user journey end-to-end.
Do you support full payload inspection?
Yes. You can fetch HTML/text bodies, headers, and metadata to make failures diagnosable.
What happens as we scale volume?
Start free, then upgrade for higher volume, retention controls, and team workflows as adoption grows.
