so, i spent the last six weeks building what i thought was a genius system. automated prospecting, used a custom gpt to personalize first lines based on site content, the whole thing. i was sending about 200 emails a day. open rates were decent, replies were okay for the first two weeks. then everything just fell off a cliff. zero replies for the last ten days, my sending domain reputation is probably toast, lmao. i have the data. the initial spike looked good, ctr on the links in the emails was okay. but it's like the algo for inbox placement just figured me out and shut the door. my guess is the personalization wasn't varied enough, left a footprint. or maybe the volume was just dumb. i was so sure this would work. anyone else tried to scale outreach with automation recently and actually had it last more than a month? what did you actually change to make it stick? data or it didn't happen, obviously.
