Regular newsletters are great but newsletters sent just because a date has arrived serve no purpose. Newsletters must be sent when there is news. If that is weekly, then so be it. If there is nothing to say then wait till there is.
Newsletters should include: New features, reminders of how some features work, future plans, links to YouTube or other videos on PGC, bugs, etc.
Newsletters take time. Precious time that could be used for more important projects.
