From my experience, Reddit is not a good platform to promote stuff if it is not entirely free (requiring email address input doesn't cut it either). As u/idunno246 said, the people who won’t put in an email address probably wouldn’t pay either. I would advise making another webpage without email opt-in for Reddit, and use the one with email opt-in form as default.
