We’re working on some new subject lines. For now, You can check this blog post https://woodpecker.co/blog/cold-email/subject-line-example/

Sure, Nick thanks for your comment. The full message expressed by our email was “We’re looking for fitness professionals who would like to test what we’ve got and offer feedback as experts.” So yes, we were looking for fitness professionals after all — I wasn’t being dishonest in the subject line. The thing was that after reading just the subject, my addresees could presuppose I’m their potential client. In the body of my email I gave them the full context of the reason I’m looking for a fitness pro. So the body was a continuation of the subject line — and I think the whole message made sense logically.

Sometimes, you can see subjects that are purely shocking or designed to draw your attention just to lose it in the first paragraph of the email. Steli Efti gives an example of such a case in this post http://blog.close.io/subject-lines. If the subject line is dishonest, you will get lots of angry negative replies or you won’t see any replies at all. The effeciency of the campaign I described in the post was close to 30% in reply rate. And we didn’t see any angry replies.

I guess the line between the intriguing and the misleading is very fine, so you need to be careful not to cross it with your particular group of prospects.
