In this guide, we will show you how to add attachments to your mail merge and send them with Thunderbird.

It is important that all files that you want to send with the mail merge are in the same folder.

1. Name the files according to the following pattern:

1. Add a new column for the attachments to your control file.
2. Enter the name of the file in the desired line.

As soon as you have finished creating your control file, you must enter the path to the files in Thunderbird. Here you can see how to find this
and where to enter it.

1. Open your Explorer and navigate to the folder in which the attachments are located.
2. Now click on the small arrow pointing downwards at the top of the bar.
3. The text in the bar should now automatically be highlighted in blue. Copy this text to the clipboard with "CTRL + C" or by right-clicking on the text and then "Copy".

4. now open Thunderbird and compose the mail. Once it is ready, click on the " Mergemail " button at the top right.

5. check the "Attachments" box.

6. Now paste the copied text into the field using "CTRL + V" or right-click on the text field and then "Paste". The path must begin with the corresponding drive letter, as in the example. If this is not the case, the path is incomplete.

7. add a "\" and then "{{attach}}" to the path as shown in the example. The "attachments" must correspond to the column heading from your .csv file.
