HELP: Multilingual Blog Subscription

Hi,

I have a multilingual blog (English, Spanish and Bulgarian) and I am using Polylang. The WordPress theme I am using is called Satisfy.

I use Email Subscribers so my readers can get a notification every time I post an article. The thing is that when I post an article, my subscribers get three different notifications for the Spanish, English and Bulgarian version of the SAME article.

Is there any way that I can send only ONE notification for the article in the language that the person subscribed to my website? Say, if they subscribed to the Spanish version of the website, then they only get a notification of the article in Spanish?

I would really appreciate it if you could help as I have tried many plugins and the problem does not seem to disappear.

Thanks.
