I've studiously watched the whole of Harry Bingham's Self-Publishing video course and got a domain on Wordpress to start a website and got an email address with Gsuite. My MS has been assessed by an excellent Jericho editor; I have a reader magnet ready... I understand that the hyperlink from my reader magnet will direct them to my landing page but how do I connect my landing page to Mailchimp, Bookfunnel and Prolific? Do I administer my mailing list through Mailchimp or my website or even through Outlook? Advice welcome.
