Install Mailbox and see every email your Laravel app sends
MAILBOX FOR LARAVEL BY NUMBERSA zero-configuration local email inbox for your Laravel app. Capture, inspect, and debug every outgoing email - no external services required.
.webp%3Fv%3D1793874514&w=3840&q=75)
Three steps. No accounts. No configuration files. No environment variables beyond the mailer.
Add Mailbox to your Laravel project and install everything it needs.
Point Laravel’s mailer to Mailbox with a single environment variable.
Every email is captured and displayed at /mailbox.
Browse all captured emails with subject, sender, recipients, and timestamps.
Switch between HTML preview, plain text, and raw RFC 822 source.
View and download attachments directly from the dashboard.
Delete individual messages or clear the entire inbox
Paginated, searchable, and responsive
You’re building email flows - welcome emails, password resets, invoices, notifications - but testing them is painful.
You get a wall of headers and encoded HTML in your log file. No way to see what the user actually receives.
External services add friction
Mailtrap, Mailhog, and similar tools require accounts, API keys, Docker containers, or running separate processes. Every team member has to set them up.
Database
Default. Uses a dedicated SQLite connection out of the box. Supports MySQL and PostgreSQL.
.webp%3Fv%3D1793874526&w=3840&q=75)
File
JSON files in storage/app/mailbox/. No database required.
Auto-enabled only in non-production environments

Gate-based authorization via Laravel’s Gate facade
Like Mailtrap - but it lives inside your app. No signups. No API keys. No extra processes. One composer require and you’re done.
1
You’re iterating on a transactional email. Instead of sending it to a real address, checking Mailtrap, or reading log files - just open "/mailbox" in your browser. Every email your app sends is right there, rendered exactly as the recipient would see it.
2
Mailbox intercepts all outgoing emails and displays them in a beautiful, self-contained dashboard.
Set MAIL_MAILER=mailbox and you’re done. No API keys, no external accounts, no setup.
Emails break silently
A broken layout, a missing variable, a wrong recipient — you don’t catch it until someone reports it or you dig through logs.
Onboarding is slow
New developers on the project need to configure an email testing tool before they can work on anything that sends mail.
.webp%3Fv%3D1793874528&w=3840&q=75)
Custom
Implement the MessageStore contract for Redis, S3, or any backend you need.
Configurable redirect for unauthorized users
.webp%3Fv%3D1793874535&w=3840&q=75)
Middleware stack is fully customizable
MIME type whitelist prevents unsafe file storage
Everyone on the team gets the same email debugging experience out of the box. No shared Mailtrap accounts, no “did you configure your mail driver?” questions. It’s in the repo. It just works.

Mailbox captures emails silently without sending them to real recipients, verify email flows in staging without emailing customers. Auto-enabled in non-production environments.
Captured mail includes password-reset links, tokens and personal data, and the default gate is permissive. Outside local dev, require authentication and a strict viewMailbox gate before enabling. Keep MAILBOX_ENABLED=false in production.
