Thank you for posting. I guess I was hoping that if you watched the webinar early enough for the October 14th window, then the points would have been posted in October. Looks like my hope wasn't justified.
Now as far as records retention policy goes, I think most major corporations expect that all emails will be deleted after 90 days unless they are required for a business record or a legal hold. I try to follow that policy. Admittedly this email falls within the 90 day window, so thanks for keeping it the entire 90 days. Emails older than 90 days may well be outdated and can be confusing. Perhaps you can interpret Power Up points emails as a business record.
