Microsoft newsletters suddenly in Spanish instead of English

Hello,  
Recently I started receiving Microsoft newsletters in Spanish, although before they were in English. It is from email domain "email.microsoft.com". I haven’t changed my MS account settings. 

❓ How can I switch back to receiving newsletters in English?  

Has anyone else experienced a similar issue with MS newsletter language, or found a way to solve it?

Last newsletter was with subject: "Dé el paso hacia la IA – Microsoft AI Power Days"

Thank you for your help.
Peter
