I was skeptical at first, but Instantly.ai actually delivered on its core promises. The interface took a few hours to really figure out, but once it clicked, it started saving me a massive amount of time. It's not perfect, but it's easily one of the better tools in this space right now.

I use this mostly for the heavy lifting. Instantly.ai handles about 80% of the repetitive work, and then I step in to polish the rest. Honestly, the output can occasionally be generic if you don't prompt it well, but once you learn how to steer it, it becomes indispensable.
