Are there any negatives side effects to using PGP all the time with email?

More specifically, if I was to attach my public key to every email — even when the recipient doesn’t use PGP. My assumption is that “life would carry on” and there would be basically no difference but I’m not entirely sure. _the process of using PGP for encrypting content (text messages for example) is something I’m only just started understanding after some reading and practicing_
