I've got a few emails recently from recruiters (who I have not met before) about jobs which are related to my skills/fields. For example, one of them get my email address from my github profile (I'm using that email address for only github commits) and put some effort to the email (she used my last name, the location of the job is the same city as can be googled about me).
However, I'm not really interested in those jobs. Should I answer these emails? Could there be any negative consequences if I just delete them? (I'm living in a small country/city.)
