thanks PatriceJ. I wasn't sure if I was clear enough. I didn't think the quiltingboard was selling my email because it is a completely different one than I use here. There were no unsubscribe instructions, as I stated in my original post. I tried that.
I will attempt to unsubscribe myself from the daily digest since I don't read it anyway (and interestingly have never missed an issue).
Just to be clear - the email came to an email address that is not associated with quilting board. I checked that first thing. And second, there are no unsubscribe instructions.
