The verification link shouldn't be used to verify the email exists, it should be used to verify that the owner of the email address is the same person that signed up for whatever service. I have a common name gmail address, and I get verification emails all the time that I never open. If websites keep emailing me after that, then I rightfully mark them as spam.
