I don't get spam emails, but I get spam phone calls. Sometimes it happened suspiciously a few minutes before a call that's actually related to the position I applied for. But a phone number is expected here where I live (Spain). Few companies seem to respond via email (some do, but it's rare). Everyone just wants you to give them your phone number so, if they decide to call you, they will do a surprise call a few weeks after you applied, at the most inconvenient moment, with no advance notice of any kind. And since first impressions are important, not being available during that inconveniently-timed surprise screening call is probably a negative point at least on a subconscious level.
