Move on.

Some people would consider the second or third email as spam, that is fine. If they block you, that means that was a dead end anyway.

My experience is that people are busy and we forget to reply sometimes. 3 emails in a row, in a matter of days, would be spam for me too.

The second email is spam, and I’d be sure to never do business with that person at that point. I’d be closing off a door at that point.

You're going to miss out on quite a few opportunities if you consider someone's second email as spam.

It hasn't hurt me so far.
