Expert from Email Geeks explains that there isn't really industry documentation, unless someone’s done some case studies, to show sending identical emails will cause ISPs to flag as spam.

It’s why fingerprinting and content matter.

Expert from Email Geeks explains that except in extremely egregious situations most of the consumer ISPs now start handling spam by moving some recipient’s mail to bulk. If the recipients go chasing it and pulling it out, they stop. If recpients don’t then more and more starts going to bulk. Each mail in bulk hurts your reputation, so now you’re in the negative spiral.

Expert from Word to the Wise, Laura Atkins, explains that one of the things that can cause filtering issues is fingerprinting. Sending messages that are extremely similar can cause your messages to go to the spam folder, because this is what spammers do.
