The overwhelming consensus from experts, marketers, and documentation is that adding a clause to terms and conditions asking users not to report spam is generally a bad idea and ineffective. Users will likely still mark emails as spam for various reasons, regardless of any contractual agreements. High spam complaint rates negatively impact sender reputation and deliverability, and these organizations use spam complaints to improve their products. A 'no spam' clause provides no legal protection. The best approach is to obtain explicit consent, provide easy unsubscribe options, and focus on sending relevant, valuable content.

The consensus is that adding a clause to terms and conditions asking users not to report spam is generally not a good idea and likely ineffective. Users will still mark emails as spam regardless of contractual clauses, primarily because they either don't read the terms, find it easier than unsubscribing, or genuinely perceive the email as unwanted. High spam complaint rates negatively impact sender reputation and deliverability.

Experts generally agree that adding a clause to terms and conditions asking users not to report spam is not a good or effective idea. While one expert notes it may simply codify a "social contract," the consensus is that users who perceive an email as spam will still report it, rendering the clause useless and potentially damaging to sender reputation. Furthermore, some experts actively report unsolicited emails to ESPs, signaling a lack of permission.

She also mentions that they even tell other people that she actively signs up for lists and then reports them, and that she is known for that.

Expert from Email Geeks shares his opinion that including a clause in terms and conditions stating that users who requested the email and no longer want it should not report it as spam is not a good idea, but it's really just putting in writing the social contract of "If you asked for the email, don't want it any more and haven't asked to unsubscribe, don't report it as spam."
