What is a restricted email address?
When a customer performs a particular action on your website like placing an order or completing your contact form, your website will generate an email to you (and to your customer).
Our system 'pretends' to send the email from the email address you set on your email notifications page in your website's settings. We say 'pretend' because the email is actually sent through our system and servers, rather than the ones that your email address uses. This is called 'spoofing'.
Unfortunately this spoofing is often used fraudulently, from spammers and other users with bad intent, and email providers don't like it.
So, for example, if you want to receive notifications of your orders to your hotmail email address and a customer completes the contact form on your website (and also has a hotmail email address), our system will send the notification of the contact form to you from your hotmail email address, to your hotmail email address. The hotmail system will detect the email sender is spoofed and fail to deliver the email to you.
Unfortunately, there's no way around this problem.
Please note that this only affects you if you have listed your email notifications to be sent from a particular email address, not your recipient email address.
