“Sign up for newsletter” linked to Magento Backend
I have a website that is HTML and a separate magento store. Is it possible to have a “sign up for newsletter” area on a HTML page that links to the magento backend? So when a customer inputs their email it’s entered into the magento database and you can see the email in the newsletter section of the magento admin.
i think you can create connection to magento database & insert query into newsletter_subscriber table in your html page
but you check some column like store_id,subscriber_confirm_code its only simple way may be help you
