Thank you for reaching out and posting this question!
By looking at your list of apps, the newsletter popup could be coming from the Hextom: Ultimate Sales Boost app so we'd recommend starting there. However, as some themes can also come with a popup function, we'd also recommend taking a look at your theme editor.
As for the free shipping message on the product pages, this could also be coming from the Hextom: Ultimate Sales Boost app. However, this can also be custom coded into your theme, so we'd also recommend taking a look at the templates for the product pages of your theme.
If you're unable to locate where to make these two changes on your store, then it looks like we'll need to access your account in order to resolve these issues. While we're unable to provide account-specific support via the Shopify Community, we'd be happy to further assist you through live chat, email, or callback. Simply visit the Shopify Help Center and log into your account to create a support request.
I noticed that you're a new member of our Shopify Community! Once you've resolved this issue, I'd love to hear more about your business and share some resources to help you get started. What kinds of products are you selling? In addition to the email marketing, do you have a marketing plan prepared for your store?
