subscrition

just wonder how does the Module mod_easyblogsubscribe works ...

i mean i know how it should work ... but it seems that it doesnt ,
i have subscribe myself to the site and i did not received any blogs entries for more then 3 weeks ...

where do you set how often the emails to be sent ?
where do you set what categories blogs to be sent out to subscriber ?
there are no setting or im missing something here ?

in eb i can see the subscriber email ... but shouldn't blogs be sent out to that email automatically on new blog entry ?

do i have to use Mailchimp Integrations for es to work ? ... please advice

thanks
