Core

Spin up a virtual SMTP server and capture every message into a single, searchable inbox.

Virtual SMTP servers

Each inbox provides host, port, username, and password-use them in your app to route test emails safely.

Catch-all inboxes

Regardless of the To: address, every email sent via this inbox lands here-no leaks to real customers.

Dedicated inbound address

Every inbox has a unique email address-send directly into Mockmail when SMTP isn’t convenient.

Collaboration

Bring QA and devs into the same testing flow without sharing passwords.

Shared inboxes

Invite teammates to specific inboxes and keep experiments private when needed.

Granular permissions

Control who can view and send via an inbox-for example, give QA access to staging only.

Multiple inboxes

Organize by environment, client, or feature to keep testing tidy.

Observability

See exactly what was sent and why-no more guesswork around templates or headers.

HTML & plain-text preview

Render both variants to verify content parity and fallbacks.

Headers & raw source

Inspect sender, DKIM/ARC fields, MIME boundaries, and the exact payload used.

Search & filters

Quickly find messages by subject or recipient, and focus on the runs that matter.

Automation

Connect your inbox to your tooling to close the loop on tests and data flows.

Webhook forwarding

Forward incoming emails to a webhook URL for real-time processing and CI checks.

Structured data

Use parsed fields like subject, recipients, and parts to automate validation.

Works with your stack

Point Nodemailer, Laravel Mail, Rails Action Mailer, or any SMTP-capable client at Mockmail.

Developer Experience

Small details that make daily testing smoother.

Fast UI

Focused inbox with quick previews and clean navigation.

Environment-friendly

Keep separate inboxes for staging, QA, and experiments.

Time-saving defaults

Sensible settings so you can plug in SMTP and move on.

Privacy & Access

Clarity and control around who can see what.

Access control

Share inboxes selectively and keep sensitive ones private.

Audit-friendly

Clear separation of inboxes and credentials per environment.

Focused scope

Purpose-built for staging and QA-not for sending production mail.
