Hey @SilverSarie, welcome to our Community!
At the moment, we don't have such functionality in Dropbox.
An alternative method that you could use, and that pops into my head is using a shared link instead of sharing the folder directly.
That way you should be able to copy the link, and send it to them however you'd like. However it's important to note, that they would only be able to view and download the content, not edit it.
I hope this clarifies!
