The email review layer for agencies.
MailSandbox is a fake SMTP sandbox that catches every email your staging environment tries to send, so nothing ever reaches a real recipient. Point any app at it — Laravel, Rails, Django, Node, or a raw socket — with just four lines in your .env, and every password reset, receipt, and digest is captured the instant it leaves, with the full HTML intact.
Built for the way agencies actually work, MailSandbox organizes captured emails by client and project, so you always know which message belongs where. Review the fully rendered HTML, catch deliverability issues early with built-in spam score analysis, and share a signed review link so clients can approve or comment without ever creating an account.
Start capturing test emails in under sixty seconds — free, no credit card required.
