Note that "a lot of spammers" isn't really a lot in laymen terms. It varies by provider, but last I worked on this if anywhere from 2-5% of all emails you send are clicked as spam the provider will start blocking you. We got blocked once because we got a single spam click: the ISP said they have a zero tolerance policy. We had years of sending hundreds of email per week without a spam click.
