How to Delete a Feed
BlogFeeder will allow you to delete a feed if you no longer need to import posts from that blog. Deleting a feed will not delete any posts that have been imported; if you want to delete these posts, you'd have to do so from the "Blog Posts" menu (which can be done in bulk if needed).
You can delete a feed by going to "Apps" and clicking on BlogFeeder. Click on the Feed name that you'd like to delete.
While in the "Edit Feed" page, scroll to the bottom. You'll see a "Delete this feed" button.
Click this and confirm to delete this feed. Again, imported posts will remain, but no new posts or post updates can be imported into Shopify from this blog when the feed has been deleted.
