You now see a simplified menu when you tap a group name, focusing on the various send options.
Less commonly-used functions such as “Rename” “Duplicate” and “Print” can now be accessed by tapping the “More…” button.
This is also where you will find the new “Save as .CSV” feature, which I added as a result of customer requests. This will export your group as a .CSV file. The file this creates can be found in the “Mailshot” folder in the “On My iPhone” (or “On My iPad”) section of the Files app, from where it can easily be loaded into Numbers or other popular spreadsheet apps, or emailed to someone.
