It's hard to even say how much we'd get from a single subscriber. This completely removes our ability to control our price if we want to be in the dominant ebook ecosystem.
I've scheduled an appointment to talk with Amazon later this afternoon. Have many questions. Fellow editors of mags on Amazon: feel free to DM/email me. We should be talking.

Further information: It appears as though other editors I've spoken with received slightly different emails. Those didn't include an invite to the KU program, so it may mean that only a few of us will be asked to stick around.

Ok, call completed. Happy to report that I did not shoot the messenger. Received a lot of useful information that will take some time to digest. Also expecting their terms and contract details along with a quote late next week.

I was told it was ok to share, so I will. KU for Magazines is different than KU for books. It will not prevent us from publishing/selling our magazine elsewhere. It is not paid per-paid, but based on an annual projection based on "qualified borrows." On the tech side it functions quite a lot like the KPP program they are discontinuing. Same infrastructure and ingestion process. (Makes me wonder why it is necessary to end the program if this is being maintained.)

@clarkesworld If the only real difference is that some magazines are being asked to stick around, and some are not, maybe that's the reason why the program is ending while still being maintained.
