The biggest mindset switch we had building this campaign wasn't about sending MORE, it was about sending BETTER. Volume done wrong is exactly what affects, and we learned that the hard way. 💧 Send like a human: Sending 500 at once from a new account is the best way to get into spam quickly. So we made the system mimic a person, warm-up (raises volume gradually), time window (office days and hours only), and one every so often, not all at once. We let it flow drop by drop, like water shaping a rock. 🛑 Automatic brake: If bounces cross a certain threshold, the campaign pauses itself and alerts us. Something funny happened here, at first it counted auto-replies like "back on Monday" as bounces and stopped for no reason. We tuned it to only count real bounces. We learned that an alarm that goes off for everything is an alarm you end up ignoring. 🔁 Follow-up depending on behavior. This part made us happy, generic follow-up, the same message for everyone, never quite convinced us, so we made the system read what each person did and react, across 4 branches: if they viewed the content, it invites them to a meeting; if they viewed it but don't reply, a close that acknowledges they've already seen it; if they opened nothing, a soft message that reopens the door; and if it's already been several touches, an "elegant close" that lets them go without pushing. One detail that cost us: the spacing. Before, someone could get two follow-ups the same day. We fixed it so each one counts from the previous one, not from the first touch. And new emails and follow-ups have separate limits, so they never compete with each other. We think looking human isn't a trick, it's respecting how email works. And follow-up isn't repeating, it's reacting to what the person did. 👉 How many follow-ups do you send before letting a contact go? We want to know how others do it, we send two, and you?!
