@RayNewman I agree with you - it is in that trust-building/call to action area that they meet. Obvs some skills that cross over too, like creating a flow of info etc.
What made me feel icky with copywriting was that, at times, it can feel a bit manipulative ... or at least it did to me. Others would say persuasive! Ultimately, how it made me feel led to me sticking with tech writing and leaving copywriting to others. Did you ever feel like that?
