Adding subscribers

Hi,
Hopefully I’ve posted this in the right place.

When I moved to hosted (with GoDaddy) my blog stopped sending out the email to my subscribers; no problem I thought & started using mailchimp to do this. It was a bit laborious, but hey, it did the trick.

Now, for some unknown reason, my blog has started sending out the new post email again.

Couple of questions.
1. Is it possible to get the subscriber link so I can replace the mailchimp link for new subscribers, which is in a widget?

2.How do I import all the subscribers from mailchimp (I have the email addresses) but don’t know where to put them.

Many thanks in advance
