Rather than sending an attachment, you can embed a text file or pdf into the text of your broadcast. This helps avoid spam filters and is a little more obvious than an attachment at the bottom of the email. To embed a file just follow the steps below:
1. Type the text you want to link to the pdf or doc into the text editor.
2. Highlight the desired text and then click the "insert image or file" icon in the toolbar.
3. You will see another pop-up that shows the currently uploaded files / images in your server. Make sure you click "files" to the left.
4. If the file you want to embed is in the main window, double click it. If not, click the "Upload" button in the top-left corner and follow the prompts to choose the file's location from your computer. When you have, it will be added to the list in your server. Double click it.
The end result will appear like a normal link, but users who click it will see the file you embedded appear in a new tab in the browser.
