@Griffin-McPherson research the companies you could use and see what they ask. In my experience with wedding invitations and birth cards they do ask for a spreadsheet in a certain format.

@Laurel-Aylesworth-0 thanks for the heads up! Gonna check this out.

Last year, right before lockdown, I had a bunch of postcards printed that never got sent out, cuz ... you know! Posting digital postcards might help to get things going (or at least get me back on track with that aspect of marketing).
