Success with electronics niches; e.g. mobile games, electronics, smart phones?

I am a beginner with a reasonable website with good content, and a small following. My niche is smart phone mods and I want to capitalize on the followers I have before they disappear. I got anxiety in getting started with CPA offers regarding, but fear that it may be an overpopulated niche. I read somewhere on BHW that zip submits were outdated. Any truth to this? My goal is not zips, but emails and pins. Anybody had success with email and pin submits?

Email submits still work okay in my opinion although the amount of scrubbing in that field always steers me away. You'll need to keep rotating different email submits because if you use 1 for too long, the CPA network will start to try and squeak by scrubs.

gotcha... its not just email. Pin as well. I plan on working hard in the paint and diff plans on pulling traffic.
