DS eMail System Thoughts

gistfile1.txt

Issues:

-> The ability to log sent messages (prevent sending the same message twice) - success or failure: tech reason or bounced email address
-> The ability to query what messages were sent
-> The ability to resend messages / send followup (apology) messages
-> Support different DS systems sending transactional messages (Drupal, Ruby, etc) - end point?
-> track number of messages sent to an email address
  => trigger digest format
  => throttle the timing of sent messages
  => how many are in the queue, to be sent vs how many have been sent recently (triggers for format)
-> sync with MailChimp subscription status
-> unsubscribe from specific campaigns
-> Send test messages through Mandrill to specific email addresses for proofing before releasing live

-> Send alerts when health checks fail

Solution

Queue / Message Broker ??

-> Rack Space Cloud Queues
-> RabbitMQ

Using Heroku to create test app to log webhook details from: 

MailChimp: http://apidocs.mailchimp.com/webhooks/
Mandrill: http://help.mandrill.com/entries/21738186-Introduction-to-Webhooks

-> Basic node.js app listening on:
