Question About Covering Tracks

If you're sending out a CPA link via email, is it necessary to use DMR or fake the referrer?

For example, say I'm getting bh leads from a site like craigslist, and I have some sort of autoresponder set up. In my reply email, I send them my CPA link.

Now, the referrer should be the email service's page, right? Because a lot of offers can be promoted via email newsletters, should I not have a problem not using DMR? Is it even better that I don't use DMR so it shows that I'm promoting via email?

i think you need to look at the offer requirement first. If they allowed email marketing the you don't need to use DMR. But if they disallowed then you need to use DMR
