Have you considered using something like Dropbox? It allows me to create links to files so I don’t have to attach anything - makes it really easy to share. Here’s an example of a Dropbox link to a file, there’s a signup process, but you don’t have to pay to access Dropbox files.
Happy to answer questions about how I do this, or you can just check out one of my posts, because I always fill my posts with lots of links!
You can send messages to multiple people on your patron list at the same time. You just click more than one check box for them and then it will send to them all together. (I do this often.)
Also yeah, it’d be really nice to be able to attach stuff to messages themselves. Though i will second Nancy on using Dropbox. That is what i do to give out my rewards currently and it does work well for what it is.
Strangely, I cannot see any check boxes on the patron list next to individual members. I see the list in relationship manager but can’t select individual members for a group message. How can I get these check boxes to appear?
