I currently write reviews for books/movies on my ghost blog at https://boydsbar.xyz. However, I might watch multiple moves a week or end up writing multiple reviews in a week. There should be some way to do a weekly email summary (such as the one suggested here) that can be done from Ghost itself.
This would also help with click through rates as it would allow for the excerpts to be added as the summary and then at the end of the week/month it would send a summary email. It would also allow for the reads to select how often they want to receive emails with a simple description of the newsletter choices.
