Suscription questions

I want to know where I can see the number and the emails of the people that suscribe my blog.

You can follow the instructions here to access your subscriber list:
http://jetpack.me/support/subscriptions/#view-your-email-subscribers

And also want to know if I can choose that some post don´t be sent by email (like an exclude category or something).

Yes, that can be done. You’ll need to use a code snippet including the slug of the category you want to exclude, and place that code snippet in your theme’s functions.php file. You can find examples of the code snippet here:
https://github.com/Automattic/jetpack/pull/2598

I can put below a post the option of suscripction.

You can place the Subscription form shortcode at the bottom of your posts:
http://jetpack.me/support/subscriptions/#shortcode

If you’d like to include that form under all your posts, you can use the do_shortcode function in your theme:

I hope this helps.

maybe is because i have desactivate the jetpack stats in the configuration?

That would be it, yes. No worries though, Jetpack Stats does not interact at all with Google Analytics, or other stats services. You can use both services at the same time without any worries.

how can i add the code in the theme?
Where i have to add that code if i want to include that in all my posts?

That depends on your theme. Typically, you’d have to place the code inside single.php, below a function named the_content.

Another alternative would be to use a plugin that hooks into that function instead. I built a small plugin to do that for you. You can install it by going to Plugins > Add New > Upload in your dashboard:

About the exclude category that dont be sent by email, its any way to do it without touching the code?

No, you’d have to build a small plugin for that option as well. If you let me know the categories you want to exclude, I’m happy to build that plugin for you.

– Before discovering Jetpack, i ve dowloades the plugin “Subscribe to Comments Reloaded”, now i can just eleiminate that and use the Jetpack option for that or would be any problem?

You can, yes. It’s probably best not to use 2 different comment subscription systems, as your readers may be confused.

the number of people that suscribes to comments is in statitics near the suscription users, but I can know for what post comments they suscribe?

I’m afraid that option isn’t available at the moment, but I took note of your feedback, and we’ll consider making these numbers a bit more detailed in a future release!

This should do the trick:

It’s worth noting that the plugin uses category slugs, and not category names, so your category slugs have to be as follows:
fotos-de-la-semana, otros, mas, jr-pass

If they’re not, let me know what they are and I’ll update the plugin,

if I put a post in more than one category (one that is exclude and one that not) it ll be sent by email?

No, no email will be sent as soon as the post belongs to at least one of the excluded categories.
