    FAQ

    How much social proof in cold email?

    One line is enough. A full paragraph of testimonials feels salesy. One relevant proof point beats five generic ones.

    Where to put it?

    After the problem/ask, before the CTA. Or in the P.S. Don't lead with it - lead with relevance.

    What if I have no clients yet?

    Use results from similar work, a relevant credential, or skip it. Relevance and specificity matter more than social proof early on.
