I agree that email shouldn't be considered secure but disagree that you should just give up as a result.

It's trivial to use an email provider in a more privacy-friendly jurisdiction (e.g. Mailbox.org in Germany) and with a bit of effort you can even move to a provider the PGP-encrypts incoming email which can then be decrypted by your email client (which can connect with IMAP).

Given that the first measure is near-zero effort and saves you from silent/warrantless law enforcement requests, I think it's worth it.

Encryption is a bit more annoying but it does save you from later disclosure of your emails.
