Do subscribers get repeat notifications to revised blog posts?

Hi.

I have Mailchimp set up to notify subscribers each time I publish a new blog post. It works a treat.

However, I’m always seeing little changes I need to make to tweak my previous posts. A spelling mistake here, a grammatical error there.

Each time I make a minor change and republish, are my subscribers getting another alert, as if I’d just published a brand new post? Or do they only ever receive a single alert per post, when the post first goes live?

Thanks
Nick
