The setup works and the urge is to pour three times more into it. That step loses more money than failed tests do: a failed test costs a hundred contacts, a failed scale-up costs the whole fleet.
Why profit does not scale linearly
The audience runs out. You worked the best venues first. The next hundred contacts come from worse ones.
Complaints grow faster than volume. More messages means a higher chance of hitting the same person twice — and they already complained.
Less attention per account. Twenty accounts you check daily; a hundred you check weekly, and you notice problems later.
The order
- Base first. Triple your venue list before adding accounts, or the new accounts walk into already-worked chats.
- Accounts second. Plus 30–50% at a time, bought a month ahead — warm-up takes weeks.
- Limits last. Only after the fleet has proven it holds the current load.
What to watch
Not volume but two things: stage-by-stage conversion and the share of accounts lost per week. Both sag before revenue does.
