Few issues while using Sharing and Shortcode embeds

It sounds like your server might not be configured properly to send emails through the wp_mail function, which Jetpack uses.

Can you try installing the Check Email plugin and sending yourself a test email to see if it works? You can download the plugin here:
http://wordpress.org/plugins/check-email/

If you didn’t receive a test email, you could try using a plugin like this one to configure your WordPress site to use a specific email service:
https://wordpress.org/plugins/postman-smtp/

If the function appears to be work properly, it means that Jetpack’s emails are filtered out before they can reach your inbox:

* They can be filtered out by your server before they even get sent out; your hosting provider should be able to check their server email logs to find out if the emails were blocked.
* They can be filtered out by your email provider. If you don’t find the emails in your spam folder, you might want to try to send out Jetpack emails to another email address, and see if you keep experiencing issues.

Let me know if this helps!

I have used facebbook shortcode to show my post but it doen’t know anything.

Could you post the exact shortcode you’ve inserted into your post here?

Thanks!
