Virtual Assistant to build up my Active Campaign email responder

Are you familiar with Active Campaign email marketing tool? Also some virtual assistant tasks. My shopify site is a consultancy that offers Membership subscriptions and there is a course for sale. It is a very niche area. I have started using Active Campaign and need to find more subscribers for my email list. The virtual assistant tasks would include putting blog posts onto the site and keeping things up to date . I supply the blog posts.
