I have the same issue. I've installed the Archive add-on in my WP dashboard. I configured it to show the newsletter date and imbedding the newsletter on the same page, but I can't see anything else to do.
I have a .csv file I exported from TinyLetter, which contains 46 previously sent newsletters dating back to November of 2016. I want to import this file so that visitors to my website can browse old newsletters if they want to. Can I do this? If so, can you give me step by step instructions?
Thank you!
