I sent an email to ALL CUSTOMERS (via Tools -> Email) and got some responses back that they do not want to receive email from my store. Now I want to mark their email in some way (without deleting the customer record) so that it is not included in the ALL CUSTOMERS list.
Now, I am aware of the Newsletter option, which will only send email to members opting to get my newsletter but many have not chosen this option and I must still correspond with them on major store issues, but I do not want to inconvenience those who don't want email.
Any ideas on how I could make sure customer's who don't want email don't get added to the ALL CUSTOMERS list of email addresses?
Thank you.
