Hi Yordan.
Thanks for your message but I’ve tried installing this and it still does not appear to work. The email is sent through WooCommerce, not via Mailchimp so this is probably the issue. “Sent Hint’ Works and it is sent via Mailchimp/Mandrill. “Waitlist” is with WooCommerce, so I don’t think this is the issue.
Could you please advise?
Thanks,
Maddie
