OpenCompany Email Service
There is not a crime, there is not a dodge, there is not a trick, there is not a swindle, there is not a vice which does not live by secrecy.
-- Joseph Pulitzer
Teams struggle to keep everyone on the same page. People are hyper-connected in the moment with chat and email, but it gets noisy as teams grow, and people miss key information. Everyone needs clear and consistent leadership, and the solution is surprisingly simple and effective - great leadership updates that build transparency and alignment.
With that in mind we designed Carrot, a software-as-a-service application powered by the open source OpenCompany platform and a source-available web UI.
With Carrot, important company updates, announcements, stories, and strategic plans create focused, topic-based conversations that keep everyone aligned without interruptions. When information is shared transparently, it inspires trust, new ideas and new levels of stakeholder engagement. Carrot makes it easy for leaders to engage with employees, investors, and customers, creating alignment for everyone.
Transparency expectations are changing. Organizations need to change as well if they are going to attract and retain savvy teams, investors and customers. Just as open source changed the way we build software, transparency changes how we build successful companies with information that is open, interactive, and always accessible. Carrot turns transparency into a competitive advantage.

The OpenCompany Email Service handles composition and delivery of emails for other OpenCompany services.
Prospective users of Carrot should get started by going to Carrot.io. The following local setup is for developers wanting to work on the OpenCompany Email Service.
Most of the dependencies are internal, meaning Leiningen will handle getting them for you. There are a few exceptions:
- Java - a Java 8+ JRE is needed to run Clojure
- Leiningen - Leiningen 2.9.1+ is a Clojure build and dependency management tool
- Node.js - v8.9.1+ of the JavaScript runtime
- Juice - Juice 4.2.2+ inlines CSS into HTML
Your system may already have Java 8+ installed. You can verify this with:
java -versionIf you do not have Java 8+ download it and follow the installation instructions.
An option we recommend is OpenJDK. There are instructions for Linux and Homebrew can be used to install OpenJDK on a Mac with:
brew update && brew cask install adoptopenjdk8
Leiningen is easy to install:
- Download the latest lein script from the stable branch.
- Place it somewhere that's on your $PATH (
env | grep PATH)./usr/local/binis a good choice if it is on your PATH. - Set it to be executable.
chmod 755 /usr/local/bin/lein - Run it:
leinThis will finish the installation.
Then let Leiningen install the rest of the dependencies:
git clone https://github.com/open-company/open-company-email.git
cd open-company-email
lein depsFor Mac OS X, download the latest long-term support (LTS) .pkg installer from the Node.js download page. Double click the package to run it.
For Linux, install nodejs with your distribution's preferred package manager, e.g. sudo apt-get install build-essential nodejs nodejs-legacy npm.
You can verify your Node.js installation by running:
node -v
npm -vThe Node.js package manager, npm, can be used to install juice:
npm install -g juiceYou can verify your juice installation by running:
juice --versionAn AWS SQS queue is used to pass messages from other OpenCompany services to the email service. Setup an SQS Queue and key/secret/endpoint access to the queue using the AWS Web Console or API.
An API key is needed for Filestack to build URL's that do image processing.
Make sure you update the section in project.clj that looks like this to contain your actual JWT and AWS SQS secrets, and your email domain configuration:
:dev [:qa {
:env ^:replace {
:open-company-auth-passphrase "this_is_a_dev_secret" ; JWT secret
:aws-access-key-id "CHANGE-ME"
:aws-secret-access-key "CHANGE-ME"
:aws-endpoint "us-east-1"
:aws-sqs-email-queue "https://sqs.REGION.amazonaws.com/CHANGE/ME"
:email-from-domain "change.me"
:email-digest-prefix "[Localhost] "
:email-images-prefix "https://CHANGE-ME.s3.amazonaws.com"
:filestack-api-key "CHANGE-ME"
:intro "true"
:log-level "debug"
}You can also override these settings with environmental variables in the form of AWS_ACCESS_KEY_ID, etc. Use environmental variables to provide production secrets when running in production.
You will also need to subscribe the SQS queue to the storage SNS topic. To do this you will need to go to the AWS console and follow these instruction:
Go to the AWS SQS Console and select the email queue configured above. From the 'Queue Actions' dropdown, select 'Subscribe Queue to SNS Topic'. Select the SNS topic you've configured your Storage Service instance to publish to, and click the 'Subscribe' button.
