Build-in-public: my agency outreach is about to hit its SMTP monthly limit days before the reset. Twenty personalized cold emails a day, each opening with a real trigger event, and the quota math finally caught up with us. Lesson I keep re-learning: outreach is not a copy game, it is a capacity game. If you cannot sustain the send rate for 90 days straight, the campaign dies right when replies start compounding. Deciding now: upgrade the sender, or throttle the daily sends. Either way, consistency beats volume.
