Summary
Pony is a Ruby app that can send emails at a set time or on a trigger of your choosing. This article explains how to use it to create an email bot to annoy people. The post is broken up into two parts. The first explains the configuration and the second is how to get auth.
You will need a passkey and an email address to use Pony. You will also need to pick a name for the app. Pony will send the email to your email address. The app will then send the message to your recipient. It will also send the content to the recipient.
You can have another bot have access to this email array file if you want to automate new subscribers. Keep in mind gmail has limits on amount of emails that can be sent per day. Another cool thing you can create is a trigger, rather then just setting it to go off at a certain time.
