Powerful Sending Infrastructure

Easy SMTP integration and a simple, RESTful API abstracts away the messy details of sending transactional or bulk email. Scale quickly, whether you need to send 10 or 10 million emails.

Sending Email Features »

POST /messages
  from = 'App <me@myapp.io>'
  to = 'bob@gmail.com'
  subject = 'Hello'
  text = 'Welcome to our amazing app!'
  html = '<p>Welcome to our amazing app!</p>'

Intelligent Inbound Routing & Storage

Route and forward email directly into your app or inbox. Email parsing turns your emails into easy-to-digest structured data and spam filtering keeps out unwanted emails.

Inbound Routing Features »

POST /routes
  expression = 'match_recipient(".*@myapp.io")'
  action = 'forward("http://myapp.io/msgs/")'

Tracking and Analytics

Searchable logs mean you always know what is happening to your email while tags make it easy to A/B test and report on your data, and all via our webhooks.

Reports Features »

GET /events
  begin = 'Fri, 3 May 2013 09:00:00 -0000'
  ascending = 'yes'
  limit = 25
  pretty = 'yes'
  recipient = 'joe@example.com'
