Afaik, with proton you can send messages that won’t open through gmail if you protect them with a password. The other person receives a message with a link to open the mail in a browser after entering the password. It’s not the easiest solution but if you want to avoid gmail from knowing the contents of a message, you can do that.

Old problems, new modi operandi.
You can send self destructing messages with Protonmail
Do Proton remotely erase the message on the recipient’s email server? Even if it’s not a protonmail server?
