What it is
Skipping warm-up is the single most common cause of fresh-account restrictions. The cost of warm-up (4 weeks of slower outreach) is dramatically less than the cost of losing the account.
LinkedIn's anti-abuse systems profile each account's normal activity baseline. A fresh account jumping to 100 invites/day is a textbook bot signature. The same account ramped from 5 to 80 invites/day over four weeks looks like a real user growing into the platform.
Why warm-up matters
LinkedIn's bot-detection model uses 'expected activity given account age and history' as one of its strongest features.
A 30-day-old account with 0 prior posts, 0 prior connections, suddenly sending 80 invites/day, is statistically near-zero for legitimate users. The anti-abuse system has near-perfect precision flagging this pattern.
Warm-up moves your account out of the 'suspicious' cluster and into the 'real user growing into the platform' cluster.
The standard 4-week curve
Week 1. Profile completion check (photo, banner, headline, about, experience). 5 invites/day. 10 likes/day. 1 post (genuine, not promotional).
Week 2. 10 invites/day. 20 likes/day. 2 posts. Join 5 industry groups.
Week 3. 20 invites/day. Comment thoughtfully on 10 posts in your industry.
Week 4. Ramp to your target volume (typically 60–100 invites/day for a healthy account).
Infonet runs all of this automatically. You set the target volume; the scheduler handles the curve, the engagement, the post scheduling.
IP consistency during warm-up
Critical detail most operators miss: do warm-up from the same IP you'll run production from. Infonet enforces this by assigning the dedicated home IP at account creation and routing all warm-up activity through it.
Switching IPs mid-warm-up resets the trust score the warm-up was building. Treat warm-up as a single continuous session.
Dormant account re-warm
Accounts that haven't been used in 6+ months need a re-warm too — not as long as a fresh account, but a 2-week ramp catches the gap. Infonet auto-detects dormancy and applies the lighter re-warm curve.
Common case: a profile gets paused during fundraising or maternity leave. When it comes back online, treat it as warm-from-medium, not warm-from-cold.
What you can't skip
If you have an existing healthy account with active outreach history: no warm-up needed. Just connect to Infonet and continue.
If you have a brand-new account: full 4-week warm-up. No exceptions, no shortcuts.
If you have a dormant account (6+ months idle): 2-week re-warm.
Customers who push past the warm-up are the ones who lose accounts. The data is unambiguous on this point.
