Your journey towards numeric sovereignty starts here !
In the United States (and indeed elsewhere), there are laws such as the Patriot Act (in force since 2001), the FISA Amendments Act (in force since 2008), and more recently the CLOUD Act (in force since 2018) which allow the US government to access data stored by US companies without a court order, even if that data belongs to foreign nationals.
This means that if your emails pass through US MX servers (Gmail, Outlook, Amazon, etc.), US agencies (the NSA, the FBI) can legally access them without informing you and with complete impunity.
In this case, it is not a question of whether or not you have something to hide. Everyone has a right to privacy, and their data should not be exploited.
Data stored in the United States is subject to US jurisdiction, even if you are European. This therefore raises a problem regarding numeric sovereignty:

Several scandals have revealed the extent of the surveillance:
Even seemingly ‘harmless’ tools such as MX records (mail servers) can expose your communications to this surveillance if they are hosted in the United States.
Fortunately, there are alternatives :
