Mailgun Sender is an easy to use Java command line tool that you can use to send messages to mailing lists or email addresses using your Mailgun account.

No programming skills are required to use this tool.

Many people don't have the time or the skills to code against APIs. So, I built Mailgun Sender for you. All you need is your Mailgun account info and your message content in plain-text and html.

Incidentally, if code is your thing, this tool is built on top of my Mailgun Manager API.

• A computer running Java 7 or higher.
• A valid Mailgun account (Note: You'll need to know your public and private API keys to run the tool)

1. Download and extract the latest release to an installation directory on your computer, e.g., ~/Applications.
2. Navigate to the installation directory.
3. Before running Mailgun Sender for the first time, you'll need to configure two properties files (mailgun.properties and mailgun-sender.properties) located in the /config directory.
4. Open a terminal window on your computer, so that you can run Mailgun Sender using command line arguments

Set the publicApiKey, privateApiKey, and the domain property values. The API keys can be found in your Mailgun's account settings.

# Mailgun account properties

baseUri = https://api.mailgun.net/v3
publicApiKey = pubkey-my-public-uuid
privateApiKey = key-my-private-uuid
domain = mg.example.com

Set the mailgun.sender.default.from.email property value.

# Mailgun Sender properties

mailgun.sender.default.from.email=Support Team <support@example.com>

If you haven't already, open a terminal window on your computer.

Note: All messages sent via Mailgun Sender require a plain-text and HTML version of the email message content. Hence, the path to the plain-text and HTML files are passed via the command line using the -p and -h options. Additionally, when sending messages there are several optional arguments, which include the following:

-c,--campaign-id <ID>                 Campaign identifier
-t,--test-mode-flag <Flag>            Test mode flag [default: false]
-f,--from-email-address <Email>       From email address [default set in mailgun-sender.properties]
-r,--reply-to-email-address <Email>   Reply-to email address

$ java -jar mailgun-sender.jar -e johndoe@example.com -s 'Test Message from Mailgun Sender!' -p plain-text.txt -h content.html

Note: In this example, the default from email address (set in the mailgun-sender.properties file) is being used because the -f option was excluded.

Send message to a mailing list.

$ java -jar mailgun-sender.jar -m test@mg.example.com -s "Test Mailing List Message from Mailgun Sender" -p plain-text.txt -h content.html

Send a message to a mailing list and set the from email address option, -f.

$ java -jar mailgun-sender.jar -m test@mg.example.com -f 'Postmaster <postmaster@mg.example.com>' -s "Test Mailling List Message from Mailgun Sender" -p plain-text.txt -h content.html

Send message to a list of recipients in the recipients.txt file using the -R option.

$ java -jar mailgun-sender.jar -R recipients.txt -s "Test Message to Recipients from a File" -p plain-text.txt -h content.html  -f postmaster@mg.example.com  -r support@skedi.zendesk.com

Note: In this example, the default from email address (set in the mailgun-sender.properties file) is being overridden with -f option and a reply-to email address is set using the -r option.

Text file with a new line for each message recipient.
