Pigeon Mail Questions

Hi! I'm trying to use the "Attachments" feature in Pigeon Mail. I added a column with Google Drive links and named it "Attachments", but the files are not being sent with the emails. Is there something else I need to do, or is this feature only available in the paid version?

I would really appreciate a quick response if possible. Thank you!

If I buy multiple codes now but wished to change the email address they are associated with later, is that possible? For example right now I would email from my personal account however in 3 to 6 months time I may set up a new account which is more generic for marketing purposes and would wish to transfer the code to that account. This is the same for several different domains I have accounts for on Google workspace.
Thanks in advance to be a response.
