6 Best Free Mail Merge Software For Windows

Here is a list of best free mail merge software for Windows. Mail Merge is basically a process that enables users to send a similar letter or text document to multiple users. It also helps users to automate the process of creating mails for a large group of people.

Using these software, you can merge constant information (main content) with variables (name, surname, address, email, etc.) without putting too much effort. Plus, in many mail merge software, you can also create contact lists from the scratch. The contact list is a very important aspect of mail merging as this list contain contacts of recipients along with variable fields. By adding contact list to these mail merge software and adding main or common content with variable fields, you can start mail merge. Besides this, you can also quickly send emails to all recipients as most of these software provide inbuilt email feature.

In this software, you can also create and manage contacts. To do both tasks, you get two separate modules namely Address Book and Letter Mail Merge Master.

Its address book is used to create and maintain contact details, names, email addresses of various people. After adding contacts, you can save the list as CSV file which is used by Letter Mail merge Master for mail merge.

According to its name, the Letter Mail Merge Master is used to start mail merge. In order to do that, launch this module and import the contact file.

Command Line Mail Merge

Command Line Mail Merge is a Windows tool to merge and send bulk email through the command line. Just like other GUI based mail merge software, this can also be used to create merge templates and mail merge fields. Plus, you can also add contact list in it to send bulk emails with slight variations to multiple people. To run this tool, you need to have Python in your system. Plus, you need to install and set up this software to merge and send bulk emails.

Let’s take a look at the complete process of installing and merging mail using this method:

  • Open the command prompt and submit this command: pip install mailmerge and press enter to install this tool.
  • Now, navigate to a folder and run this command mailmerge --sample
    to create three sample files in that folder namely mailmerge_database.csv, mailmerge_template.txt, and mailmerge_server.conf.
  • Open the mailmerge_template file and edit various predefined mail merge fields ({{email}}, {{name}}, {{number}}, etc.). Data of these fields change according to different contacts. Main body of the text that remains constant in all mails can also be defined in this file.
  • Now, open the mailmerge_database.csv file and define both the merge fields and fields data.
  • After that, open the mailmerge_server.conf file and then specify the SMTP settings according to the email provider you are using. By default, the settings are for Gmail, so if you want to use Gmail to send email, then just put your email address there in front of “username” parameter.
  • Lastly, run this command: mailmerge --no-dry-run --no-limit to merge and send emails to all specified contacts.

This will send emails to all contacts in one by one manner that can also be tracked from the command prompt. Overall, it is a pretty good command line tool to send merge mails.
