Email testing for agencies.

The fake SMTP sandbox that catches emails from any staging environment. And organizes them for all of your clients and projects.

• Unlimited fake SMTP inboxes
• Unlimited clients
• Unlimited projects
• Spam score analysis
• Whitelabeled subdomains
• Share email via test URLs

How it works:

1. Point your SMTP here: Four lines in .env. Works with anything that speaks SMTP: Laravel, Rails, Django, Node, or a raw socket.
2. We catch every email: Password resets, receipts, digests: every message your app tries to send is captured the instant it leaves, with the full HTML intact. Nothing reaches a real recipient.
3. Review, sorted by client + project: Every inbox belongs to a project, every project to a client, the structure your agency already thinks in. Open a message to review the full HTML, then share a link so clients can check it without an account.

Features:

• A real fake SMTP: Catches every message on a standard SMTP endpoint and stops it there. Nothing is ever relayed to a real recipient.
• Full HTML preview: See each email rendered exactly as it will land in an inbox, with the raw source one click away.
• Client + project structure: Unlimited inboxes grouped by project, projects by client. The structure your agency already thinks in.
• Shareable review links: Send a signed link. Reviewers approve or comment without an account, and you can revoke it anytime.
• Spam score analysis: Every captured email is scored, so you catch deliverability issues before your client ever does.
• Whitelabel subdomains: Serve review pages from your own domain, with SSL. Clients see your studio, not ours.
