Blogspot query about email reply

Hello everyone,

I am using blogpot for my blog and am still learning how to use the backend aspects.

Currently my site has a 'follow by email' option where my readers can opt to receive the posts in their email accounts. Some of them come back to my actual site and leave their comments for the post. However when I reply to their comnent, they do not receive it via email and can only see it if they come back to my site.

I think this is quite tedious for the reader to do in case he is interested in knowing my reply. Could someone please guide me as to how to automatically get the replies to comments going to their email accounts?

Thank you for your help
