Some customers complain they do not receive our confirmation of order emails, and we ourselves don't receive copies of the confirmation emails to our shop email address (
[email protected]) - we've had to set the copy email address as my private email address in order to receive copy confirmation emails, and emails sent via the "contact us" facility (as they don't come to our shop address either). I have checked our spam filter and they are not in there, and the customers I have checked with say the emails are not in their spam filter either.
