I have used ghost to create a blog for my main website. Now I want to prompt user to register for my newsletter i.e. blog on my main website when the user is registering. Is there any way for me to push that user email to my subscription list on the blog when the user signs up on my main website (given they check on the newsletter subscription)? The only way I could think of so far was to update a list of subscribers on my main website and upload the list of those users manually on my ghost blog. But that is clearly not an ideal way.
Apologies in advance in case this question comes across as very stupid
Thanks a lot in advance.
