Old mixers that are been running for several years already have returning clients, it's the new and not fully established mixers that need marketing and promotions

This is partly true, but every service needs advertisement, even if they have been operating for a long time. There are services on bitcointalk that have run their signature campaign for years, but they didn't stop, and it is because advertisement keeps your service in the minds of your customers, if you stop advertising, it is possible people might forget about your service and use the ones that are advertising their services.

Returning clients also have to be careful, there have been many failed mixers that were advertising in the forum before they failed, and some of them were still accepting deposits even after they failed and were not processing withdrawals, imagine a returning client who is not aware of this info, whatever they deposit is lost for good.

They can still research for feedback, some bloggers and articles mentioned mixers although not by recommendation if the article is reputable and there is negative feedback on mixers in their article they will take them down and retain only mixers that are servicing people who need mixers, you can always find complaints and feedbacks from mixer users in the internet, one of these platforms is Reddit, where the community admin allow discussion about mixers.
You just have to be diligent with your research.
