A brand-new account, or one that has been dormant, is the most fragile. It has no history, no established network, and no track record of normal behavior, so LinkedIn watches it more closely. The single biggest mistake in LinkedIn outreach is pointing automation at a fresh account on day one.
The safe approach is to spend one to two weeks using the account like a real person before any automation runs. Complete your profile with a photo, headline, and experience. Connect with people you genuinely know. Engage with a few posts. Send a small number of personal, hand-written invites each day. The goal is to build a normal-looking history so that when you do start sequencing, the activity blends into an established pattern rather than appearing from nowhere.
When you do introduce automation, ramp slowly. Start near the low end of the daily limits (around 15 connection requests per day) and build up over several weeks rather than jumping straight to the ceiling. A gradual curve is far safer than a cold start at full volume.
