Mail merge using C#

Our product provides a powerful Mail merge API to build your own advanced software solution. Whether you need to create personalized emails for clients, generate a report based on the received data set or create a personalized document for any purpose, our product API can easily handle it.

With our .NET solution, you can perform a Mail merge operation in C#. To do this, use the merge template in Word, PDF or other file format and the source data.

Note that the Mail merge template must contain the merge fields into which the source data will be inserted after the Mail merge operation is executed.

Automate emails using Mail merge in C#

Use Mail merge to automate email creation and sending bulk emails. To do this, create an appropriate Mail merge template with merge fields and then automate the mailing by substituting data from your source. For example, you can create an email template with Mail merge fields instead of your customer names. Using Mail merge, you can fill in these fields with client names pulled from your data source.

So you get the fast and easy way to create thousands of personalized emails in seconds!

Build reports using C#

You can generate reports with Mail merge in C#. You still need to create a Word, PDF or other file format Mail merge template with merge fields. Such fields will be used to substitute data from the data source and build a report.
