    Generate demo Mail Templates and configuration files

    To generate demo files, use the following command.

    bulkmail demo

    Configuration file

      "credentials": {
        "email": "{{EMAIL}}",
        "password": "{{PASSWORD}}", // turn on less-secure-apps to send emails: https://myaccount.google.com/lesssecureapps?pli=1
        "host": "smtp.gmail.com", // depends on what service you are using
        "port": 465, // 465 / 587
        "secureConnection": true // boolean: true | false
      "mail": {
        "subject": "Heya {{fname}} {{lname}}! Just wanted to say hi!",
        "from": "Chandler Bing <chandlerbing@friends.com>", // keep the format
        "to": "leads.csv", // path to csv (relative to where this file is)
        "theme": "themes/Newsletter/theme.html", // path to csv (relative to where this file is)
        "attachments": [
          // relative path to the attachment files. Keep this array `empty` if no attachments.
            "filename": "{{fname}}'s Demo CSV.csv", // You may use string patterns in fileName
            "path": "leads.csv" // You may use string patterns in path too!
            "filename": "{{fname}} {{lname}}'s Resume.pdf",
            "path": "https://raw.githubusercontent.com/KumarAbhirup/resume/master/Kumar%20Abhirup%20CV.pdf"
      "configuration": {
        "mailInterval": "*/10 * * * * *", // Cron Expression: To mail every 10 seconds [ >= 10 seconds recommended ]
        "verbose": true // boolean: True if you want a log of the live process in the terminal.

    Send the Mail 🔰🔰🔰

    EMAIL="chandlerbing@friends.com" PASSWORD="secret" bulkmail -f bulkmail.json # reference the configuration file here 

    That will start the mailing process! After every mail it sends, it updates the configuration file with the emails that you sent the message to. So that when you run the same campaign next time, it will resume from where you paused. To start over, you can append the --restart flag to the command.

    Writing data in CSV

    List emails the right way

    If you use WordPress, you may just import the CSV file of users by using this plugin.

    • When you use that plugin, just change the user-email column name of the CSV file to just email so that to ensure no errors.

    If you are feeding data from any other source or by manual means, please for the GOD's SAKE ensure that you list emails only under the email column.

    If the CSV file has emails fed in some other coulumn name (such as user-email, allEmails, etc)... bulk-mail-cli would simply throw an error to *not work at all.

    Dynamic data

    You may add any other column featuring custom data in the CSV. Namely fname, lname, address, etc... to use in the Subject and Body of your campaign mail. You can use the CSV fields everywhere in the configuration files.


    The syntax can be used in the email section of the CSV and can also be used everywhere in the configuration file and HTML templates. The syntax will be processed by bulk-mail-cli to generate correct mail output.

    {{Hi|Hello|Howdy}} 🙌
    My name is {{fname}} {{lname}}.
    How'yooou dooooing? 😁


    You can also define PASSWORD environment variable so that you don't directly type it in the configuration file.


    PASSWORD=ThisIsAPassword bulkmail --file bulkmail.json


      "credentials": {
        "password": "{{PASSWORD}}"
