The possibilities are enormous.

The proportion of people who make $6k+ per month from email marketing, just like the proportion of people who make $6k+ per month from CPA, is very small. This is true of all "internet marketing", though (and perhaps true of most other forms of attempted self-employment, too)? You know this already, right?

It's true that with email marketing (typically for affiliate marketing, as opposed to CPA, of course), there's no real ceiling on earnings, so there are possibilities of earning much more. But most people don't.

I can't prove this, but for what it's worth, I strongly suspect that if you look at successful internet marketers who are earning two or three times as much as that (say $12k - $18k per month) you'll find that they're all (or very nearly all) doing so through some form of email marketing.

So perhaps the potential is higher.

But perhaps the proportion of people who actually achieve it is lower?

It's very difficult to know, of course, because (as is true for many things in internet marketing) there are no officially collated figures, and indeed no official method for collating them!
