Integrating ConvertKit with Ghost using Zapier

Hey guys! I’m planning to use Ghost as a blog and (a free) newsletter but would like to use ConvertKit as my newsletter provider by integrating it with Zapier but not sure which integrations are the most crucial.

I saw that there is a way to sync new subscribers from Ghost to ConvertKit but the question is, will that make sure that they are only in one email list which is the one by ConvertKit or will they be in two email lists, one by Ghost and another by ConvertKit. Maybe I can share what my end goals are you could help me out (:

  1. I want every time a reader clicks subscribe on the blog he will automatically be added to my ConvertKit newsletter (not to Ghost preferably)

  2. Send every single email including welcome emails, drip campaigns, or regular emails through ConvertKit

I appreciate any advice. Thank you
