What happens after you sign up?
A person sets your account up, so the first thing that happens is a check that everything the campaign needs is in place, including the target accounts you chose during onboarding. If anything is missing, your dashboard and an email tell you the one thing we need, and setup finishes as soon as it arrives.
Once your account is connected, growth usually begins within 12 to 24 hours. The first two to three days are a warm-up: we test your targets, watch how their audiences respond, and ramp activity up gradually rather than starting at full speed on day one. That is deliberate, and it is part of what keeps accounts safe.
Your dashboard can take up to 48 hours to fully populate. An empty chart on the first morning is normal, not a fault. Once data is flowing you will see your follower movement, your campaign status and, a little later, how each of your targets is performing.
One timing detail worth knowing: if setup was ever waiting on something from you, growth counts from when your account was actually connected and active, not from the moment you paid. The fastest campaigns are the ones where setup is completed on day one, so if your dashboard says we are waiting on anything, that is the thing to do first.
