Looking for a way to get an e-mail list.

You can use Wordpress+ MailPoet, Mailchimp, Awebber, ect. Most platforms are free up to 1k-2k email subscribers. You can also hook up most email platforms to other platforms like eccomerce stores and other stuff. You can make an insane ROI if you get in the opt ins so don't worry on spending money after worry about the content creation, traffic, and opt-ins

Edit: I don't have a script but if you want html code for an opt in page I can help​
