1. In most EU countries we need by legal reasons "double opt-in" after putting email address into newsletter form. This should be added without using a Flow process for any version running in Europe (opensource edition has no Flow capabilities).
2. I guess that the mailing system doesn't have "Bounce Management" that brings the risk that the Email server receiving the newsletter may block the sending email server once a certain limit of unvailed/deleted emails has been received.
3. A nice feature would be a "email content checker" against spam content that shows the evaluation of the email text written in the campaign. There are known methods how a spam filter works and a function could warn the newsletter author before sending a mail with content that would be classified as spam from most spam filters.
4. Another feature could be split test for emails campaigns when the author provides two slightly different versions. For this feature only the first 20% of emails are sent while the more successful version (e.g. more clicks/openings) of the first two hours will be used for the remaining 80%.
