Installation instructions
All the following examples run EmailEngine with the default configuration. In most cases, you probably want to use specific settings, e.g., to change the Redis connection string. You can read about all the possible configuration options from the configuration page.
Install Redis using Homebrew
$ brew update
$ brew install redis
$ brew services start redisDownload emailengine.pkg and run the installer. emailengine executable is installed to /usr/local/bin folder.
$ emailengine --dbs.redis="redis://127.0.0.1:6379/0"If you want to upgrade EmailEngine to the latest version, download the emailengine.pkg and run the installer.
To uninstall, delete the executable file from
/usr/local/bin/emailengine
Install Redis from the RedisLabs repository
These specific instructions apply to Ubuntu. See other options from the Redis homepage.
$ sudo apt-add-repository -y ppa:redislabs/redis
$ sudo apt-get update
$ sudo apt-get -q -y install redis-server
$ sudo systemctl enable redis-server
$ sudo systemctl start redis-serverDownload the compressed emailengine.gz executable, extract it and store it in a suitable location.
$ wget https://github.com/postalsys/emailengine/releases/latest/download/emailengine.tar.gz
$ tar xzf emailengine.tar.gz
$ rm -rf emailengine.tar.gz
$ sudo mv emailengine /usr/local/bin$ emailengine --dbs.redis="redis://127.0.0.1:6379/0"If you want to upgrade EmailEngine to the latest version, re-run the commands listed in Step 2. and restart EmailEngine.
Ubuntu / Debian
You can use the included install script to set up:
/opt/upgrade-emailengine.sh)Important Notice: Please refrain from running the installer on an Ubuntu machine currently in use for other applications. The installer configures multiple components that may potentially conflict with your existing setup. In such case use the general Linux instructions above.
First, download the installer script.
$ wget https://go.emailengine.app -O install.shor
$ curl -L https://go.emailengine.app -o install.shAnd then
$ chmod +x install.sh
$ sudo su
$ ./install.sh example.comWhere
NB! Tested with Ubuntu 20.04 and Debian 11. Might not work with other OS versions. Must be run as root.
If the installation process gets stuck in random places, the instance size is usually too small.
There is no official build of Redis for Windows. You can install a compatible alternative like Memurai or configure EmailEngine to use a remote Redis instance.
Download emailengine.exe executable and store it in a suitable location.
In PowerShell, run the executable:
PS C:\Users\user\Downloads> emailengine.exe --dbs.redis="redis://127.0.0.1:6379/0"If you want to upgrade EmailEngine to the latest version, download and replace emailengine.exe.
EmailEngine is available on the DigitalOcean Marketplace as a 1-Click Application. When spinning up the application, you can choose either the included Redis instance or the managed DB option. If you do not choose the managed option, you are responsible for backups yourself.
The following link is a referral link that gives you free credit if you are not yet a DigitalOcean customer.
NB! Use an instance with at least 2GB RAM
If you want to upgrade EmailEngine to the latest version, log into the server with ssh and run the following command:
$ sudo /opt/upgrade-emailengine.shUse the "Deploy to Heroku" button to set up and run EmailEngine on Heroku. You only have to set the name value on the application configuration form; other fields can be left as is.
NB! Heroku, as a platform provider, has unique quirks. Like killing long-running connections by default. This might or might not have an effect on how EmailEngine is able to operate. It is suggested to use Heroku only if you already use it for everything else, so it would make little sense to use an alternative host. And probably over-provision. If you need 2GB, you better get 4 GB.
Heroku also has Redis connection limits other providers do not have. Each EmailEngine worker thread opens a bunch of Redis connections, and if you are using a low-end Redis dyno, the available connections will be exchausted quite soon.
CapRover has native support for EmailEngine. To install it, open the "One-click apps" gallery in your CapRover installation and search for EmailEngine.
From the setup form, fill in the app's name. Set it, for example, to "emailengine".
Once EmailEngine has been installed, make sure to enable HTTPS. Additionally, check the "Force HTTPS by redirecting all HTTP traffic to HTTPS" checkbox.
Next, click on the application URL to open EmailEngine.
If you want to upgrade EmailEngine to the latest version, log into the CapRover admin page. On the Apps page, select your EmailEngine app and navigate to the Deployment tab.
Find the Method 6: Deploy via ImageName input field and enter the following image name:
andris9/emailengine:v2Next, click on the Deploy now button.

Download and extract application files
$ wget https://github.com/postalsys/emailengine/releases/latest/download/source-dist.tar.gz
$ tar xzf source-dist.tar.gz
$ rm source-dist.tar.gzPrepare configuration by creating a dotenv file with example values (see all configuration options here).
$ echo 'EENGINE_WORKERS=2
EENGINE_REDIS="redis://127.0.0.1:6379/8"' > .envStart the app. Configuration is loaded from the dotenv file
$ node server.js
