Absolutely. Your email has an image? Maybe spam. Your email does not have an unsubscribe link, even if has nothing to do with transactional emails? Spam. Your email is from an address or domain which did not send many emails before? Spam.

It feels the meme from parks and recreation.

And you can’t reliably even know if your message was received or not, the only way to do that is asking directly through some other channel…so the fact that email is open is essentially just an empty quality.
