 # apistar-mail
 
+[![Build Status](https://travis-ci.org/androiddrew/apistar-mail.svg?branch=master)](https://travis-ci.org/androiddrew/apistar-mail)

 Provides a simple interface to set up SMTP with your [APIStar](https://github.com/encode/apistar) application and send messages from your view functions. Please note this work derives largely from the [Flask-Mail](https://github.com/mattupstate/flask-mail) extension by 'Dan Jacob' and contributors, but has been modified extensively to remove Python 2 support and be used as an APIStar component.
