Free Birthday and Anniversary Mail Sender Software

How about setting up an automated mail sender application which sends the birthday and anniversary mails to the employees in your organization ? It will be awesome right!!!! Let’s find out how to make it happen.

The GitHub Link :

I have written an application in my free time to send birthday and anniversary mails to our colleagues. You can use it too as I have made it completely open source licensed under Apache-v2.0. Here is the complete link of the source code from GitHub.

The Hello-World Application

Requirements :

  • CentOS Linux Recommended for hosting the application
  • MariaDB to store the configurations and email contents
  • JDK 1.8
  • JavaMail (Or you can configure your own SMTP server)

Features :

  • All the configurations are in Database. Any configuration change is picked up quickly by the application.
  • Configurable email templates
  • Free-marker support.
  • Add multiple probable mail content and the application will select one of them randomly.

Installation Instructions :

  • Download the source from the above link
  • Build the application by running the command –
$ mvn clean package
  • Run in background –
$ nohup java -jar /home/centos/hello-world-0.0.1-SNAPSHOT.jar > /var/log/hello-world/hello-world.log &
  • Checking detailed log –
$ tail -f /var/log/hello-world/hello-world.log

Application Properties :

As this is a Spring Boot Application, below is the application properties that you will need to configure the Data Source, Logging and the SMTP Mail Server. Note that, if you don’t have a SMTP mail server, this application can also run on JavaMail dependency.
logging.pattern.file= %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%

# Spring DataSource properties
spring.datasource.driver-class-name=org.mariadb.jdbc.Driver = org.hibernate.dialect.MySQL5Dialect

############# MAIL CONFIGURATION ##############

Running the Birthday and Anniversary Mail Sender :

Once you complete setup the configuration, it is recommended to start your application in background in a server. To run the application you need to fire the below command from your terminal.

java -jar hello-world.jar --spring.config.location=<link to your customized properties file>

More details about the application and all the configuration for setting up is provided in the README file of the GitHub Repository.

I hope this application will bring some smiles to your colleagues when they will receive those greetings on their Birthdays and Work Anniversaries.

Hi There !!! I am a Software Engineer and I am always in a process of learning something new. I love the works that are outside my comfort zone. Rather than focusing on a particular programming language, I try to focus on the design patterns and technologies because I believe, if someone understands the "What" and the "Why" part of a problem and the technology or tool, then the "How" part can be easily done by any of the programming language available in the market.
