2 Ways of Uploading Attachments
Using Attach Files Button (Attachment shows in the body of message)
Using Record and Upload Button (Attachment shows inside the main viewing area)
I. Using Attach Files Button
Click the paper clip icon or the Attach Files Button
Select a file from your computer or drag and drop the file inside the window
Notice if I attach it using the paper clip in the body of the message, you have a little icon so that when your viewer or your recipient of the email receives it, they will see the attachment and right where they can actually click and download it.
II. Using Record and Upload Button
Click the first button in the toolbar or the Record and Upload Button
Click Upload
Select a file from your computer or drag and drop the file inside the window
And now in this instance, because I've used the upper toolbar, it allowed us to create a PDF inside the main viewing area.
That's it for creating attachments. You can either decide if you would like to have it inside of the main viewing area or you can include the attachment inside of the body of your message
