CAM Plus Invitation Emails

I just got an email asking me to enroll in Cam Plus unlimited for $3.99 a month (for the first month) then $9.99 for the following ones.
The Subject of the Email was “Go Unlimited with Cam Plus”!
I have been a Cam Plus Unlimited member that pays yearly since inception of Unlimited.
Why do I keep getting these emails and popups in the Android app?
It says clearly inside the App under Account that I have been a member since 2021.
Is there something we can do to block this?

At the very bottom left of your email, you will find an “Unsubscribe” link.

Clicking it will lead you to “Manage Email Preferences” where you can opt out of receiving promotional emails.
