I am using the newsletter plugin for a client and they recently have had members who received the unsubscribe email when they didn’t unsubscribe. I checked the SendGrid logs, and it looks like almost 1800 members were unsubscribed in 1 day (about 1 user was receiving the “You’ve been unsubscribed” email every minute). Is this happening for anyone else? Is there anything I can do to solve this? This is urgent
