EU-Alert system implemennts alerting via cell broadcast on national levels. Some national alert chose to also support additional ways of distribution (e-Mail, SMS, ...). See implementation by member states.
(I obviously started with the list of countries in the European Union+Swiss+UK). The list could be extended for all countries on the European continent.
ℹ️ To keep the list manageable, I'll link to english resources first, whilst indicating the other native languages. This is based on the idea, that anybody reading this should be capable of understanding English, and be able to to navigate the page to its native version.
