Send a test email. One paste, no account.
Email testing for staging, QA and CI
Pick your stack, copy, send. The email lands in a private sandbox, rendered and checked. Nothing reaches a real inbox.
Paste it in a terminal. It sends our “Welcome to Mailclutch” email.

- Drops into
- and anything else that speaks SMTP
Mailclutch captures every email your app sends, keeps every project apart, and puts your whole team in front of it.
One project per client. Or per environment.
Structure
An organization holds every project. Each one gets its own SMTP credentials, its own address and its own members, so staging for one client can never write into another.
A mail client, not a debug panel.
Inspection
Rendered HTML through an image proxy, raw source, the plain-text part, grouped headers and attachments. The deliverability score sits in the tab next to them.
Sign-off in a link, not a screenshot.
Collaboration
Send one email or a whole project to a client, a PM or a designer. They open a page in their browser. Nobody buys a seat to approve a template.
One organization, every client apart.
A project per client or per environment, each with its own SMTP credentials. Grant access project by project: a contractor working on one onboarding flow sees that project and nothing else. Closing a client is deleting a project, not cancelling a plan.

Read it the way the recipient will.
Rendered HTML, raw source, text part, full headers and attachments, in the tabs you would expect from a mail client. Next to them: SPF, DKIM, DMARC, BIMI, List-Unsubscribe and a SpamAssassin score, so a template that would land in spam says so before you ship it.

Review together, in real time.
The inbox updates live, and you can see who else on the team received the same message. Share a single email or an entire project as a link, password-protected if the content is sensitive. Whoever opens it needs no account and takes no seat.

Mailclutch speaks plain SMTP. Anything that sends mail can send to Mailclutch: no SDK to install, no provider to patch, no separate build of your app.
23 ready-made examples — and any other SMTP client works just as well.

Quick start
Copy these variables into your project's .env file.
MAIL_MAILER=smtp
MAIL_HOST=smtp.mailclutch.com
MAIL_PORT=587 # 25, 465, 587, 2525 available
MAIL_USERNAME=mc_… # sandbox "Sandbox"
MAIL_PASSWORD=pw_…
What's in the box
SMTP per project
Every project gets its own username and password. Point staging at them and each message is caught.
A real address, too
Every project has its own @mailclutch.com address. Anything sent to it lands in the project.
Deliverability score
SPF, DKIM, DMARC, BIMI, List-Unsubscribe and a SpamAssassin verdict on every captured message, from Indie up.
Full-text search
Subject, sender and body, across every email you have ever captured.
Nothing ever reaches a real inbox.
Trust
Staging mailboxes hold the most sensitive data your application touches. Mailclutch treats them that way.
Encrypted in transit.
STARTTLS on the SMTP endpoint, HTTPS on everything else. Webhook and two-factor secrets are encrypted at rest.
TLS · STARTTLS on 587
Hosted in the EU.
Application, database and object storage all run in the Paris region. Captured email is never transferred outside the European Union.

Accounts you control.
Two-factor authentication, session and device management, alerts on new sign-ins, and an activity journal on every account.

Pay for seats, not volume.
Pricing
Every plan captures unlimited email. Paid plans keep it for as long as you want it. Share links never take a seat. You pay for the people who work inside Mailclutch, and nobody else.

Changelog
Account activity journal
Every action on your account is now recorded — sign-ins, invitations, project deletions, share links — in an append-only journal, with an explicit allowlist deciding what each line is allowed to carry. The organization-wide audit log builds on it and is next.
Sessions & device detection
See every active session with its device and approximate location, and revoke it in one click. Signing in from a device the account has never used sends a security email with a link that ends that session and records it as disavowed.
Two-factor authentication
TOTP two-factor with recovery codes, plus hardened GitHub and Google account linking — every link, unlink and recovery-code use is now an event you can read back.
Catch it in staging, not in support.
