Build-in-public: my cold email batches just hit 25 of 25 sends three days straight, 205 of 210 delivered, zero hard bounces. The lesson is not about volume, it is about the boring daily habit behind it. Clean lists, real personalization, warmup that never stops, and checking the numbers every single day. Anyone can send 25 emails. Keeping them landing in Primary while you scale is the actual product.

Treating deliverability as the product is a good framing. Do you track reply rate alongside inbox placement? I've seen the two drift apart once personalization starts getting templated at scale.
