Sandbox Smtp Server

Send emails to our sandbox smtp server: no need for your own and no chance of accidentally spamming people.

SMTP Protocol Support

An authenticated SMTP server using STARTTLS to provide a solution for any programming language that can send emails via SMTP.

User filtering

Attribute emails to particular users through the use of standard SMTP headers - lets your users see only the emails they're creating.

API Adapters

Send emails via your favourite API instead of SMTP. For example, use Imitate Email to mock Mandrill

Mailbox App

View your emails (and anyone else you have access to) via your dashboard.

View in different formats

View your emails as HTML, plain text or in their Raw format. Then see how they appear across desktop and mobile.


Filter emails according to the project, the environment as well as the user that sent the fake email.


The mailbox viewer is completely responsive, enabling you to use the app on your desktop as well as your phone. Desktop emails are scaled on mobile so that you can see their desktop layout.
