Mail Merge enables users to send a similar registered email to multiple recipients, customizing certain data. Emails are stored as individual transactions. It works with two documents, the data file (Excel) and the letter template (Word). The data file includes the information of the recipients to whom the letter is to be sent. 

Requirements

- Microsoft Windows (contact RMail for instructions if you are using a Mac).
- An IMAP compatible mail client like Microsoft Outlook or Gmail.
