You’ll need to hope I can guess it. But in most orgs this isn’t a problem. My guess is nearly all email is within an organization where no one chooses mail programs.
If you send a plain text email you’ll likely get one in response. But the chance you’d get an initial email as plain text is pretty slim. There is no way it somehow becomes the default except in situations where it’s clearly prescribed up front.
