I have worked closely with Amanda Turner on a journey of discovering how to use ConvertKit for regular newsletters. After manually inputting 500 names and email addresses we got it successfully working, and now we can send professional-looking emails easily. Amanda likes to write out all the text, and then I use that to create the design. I make sure the text gets broken up so it is easier to read, with small and clear sections for promotions, top tips, quotes etc... This means she can now keep customers updated, and promote her events and retreats, and she has successful results with higher than average open and click rates. I can't attach the full newsletters here, but if you would like to see them, please email me and I can forward them to you.
