Why didn't I receive a notification for a 13G filing?

Historically, we have not sent notifications for 13G filings simply because of the volume. BlackRock and Vanguard both own more than 5% of most companies, and they are required to file 13G, so when they file, the volume of emails is enormous. We used to do this but the complaints were significant and people accused us of spamming them, etc. so we had to stop.

In an effort to solve the email volume problem while still notifying on significant events, in January 2021 we updated the notifications to send an email alert for 13G filings that include any NEW positions. So the idea is that if a 13G is filed by an institution and it represents a NEW position, then an email notification would go out.
