DoubleZero

DoubleZero is a self-hosted email platform built to work with Amazon Web Services Simple Email Service. Instead of paying monthly fees to companies like SendGrid or Mailchimp, you install this software yourself and connect it to your own AWS account. This gives you full control over your email sending at a much lower cost.

The tool provides a clean dashboard where you can send emails, track delivery status, monitor bounces, and view recipient activity. It connects to AWS SES through a simple setup process using SST configuration. You get all the features you need for transactional emails, like password resets and notifications, plus marketing features in the Pro version. The software runs in a Docker container, making it easy to deploy anywhere.

Getting started with DoubleZero takes a few clear steps:

• First, clone the GitHub repository to your computer and make sure you have AWS account credentials ready.

• Set up your environment variables including AWS keys, region, email identity, and other required settings listed in the documentation.

• Run the SST deploy command to automatically configure your AWS SES pipeline. This sets up the connections between SES, SNS, and SQS needed for tracking.

• Deploy the Docker container to your chosen hosting platform, whether that is AWS, Railway, or another service.

• Visit your hosted URL and register your first user account. Then verify your domain in AWS SES by adding DNS records.

• Start sending emails through the REST API or using the JavaScript client library. Monitor all activity through the web dashboard.

The Pro version adds features like WYSIWYG editor, contact management, email lists, broadcasts, team features, and automation workflows.
