This page explains exactly how LinkedIn campaigns send on WarmySender, why acceptance rates can appear to lag for a day or two, and what happens if your LinkedIn account disconnects. WarmySender is a 4-pillar platform — Cold Emailing, Email Warmup, LinkedIn Outreach, and Multichannel sequences. This page focuses on the LinkedIn pillar.
Account safety always wins. WarmySender never exceeds LinkedIn's safe daily limits — even when there is a backlog after a pause, a reconnect, or a quiet day. The platform will catch up at the safe pace, not faster.
Each LinkedIn campaign has a schedule_days setting — the days of the week the campaign is allowed to send on. Common patterns: weekdays only (Mon-Fri), Mon/Tue/Wed only, or Tue-Thu.
If you set Mon/Tue/Wed and today is Thursday, you will see 0 sends in the dashboard. That is by design, not a bug. The campaign is correctly idle and will resume on the next scheduled day.
You can edit a campaign's schedule from the campaign settings. Changes take effect on the next scheduler tick.
Each campaign has a sending window — a start hour and an end hour, in your campaign's timezone. Example: 9:00 to 17:00 IST (Asia/Kolkata).
Outside the window, the system queues sends — it never sends. If you launch a campaign at 18:00 local time, the first send goes out at the start of the next valid window.
Times shown in the dashboard are converted to your campaign's timezone, not the server's. If a campaign says "next send 9:14 IST", that is 9:14 AM in Asia/Kolkata regardless of where you are.
New LinkedIn accounts start at a conservative daily cap (around 10 invites per day) and ramp up over 4 to 6 weeks to full capacity. This matches LinkedIn's safe limits — automation that fires hundreds of invites on day one gets accounts restricted, and a banned account is unrecoverable.
WarmySender will never exceed your account's current ramp cap, even if you have a backlog of prospects waiting. Throughput catches up naturally as ramp progresses. We do not bulk-replay missed sends after an outage for the same reason — that would breach the safety envelope.
Per-account limits we enforce: daily invites, weekly invites, daily messages, daily InMails, daily profile views, daily endorsements, and per-action stagger delays. Each of these has its own ramp curve.
Your campaign schedule is Mon/Tue/Wed, 9-17 IST. You invited 50 people on Tuesday. Vishwanath accepts your invite on Friday afternoon.
If you want follow-ups to fire faster, change the schedule to weekdays. If you want LinkedIn safety to hold, leave it.
When someone accepts your LinkedIn invite, the signal flows: LinkedIn → Unipile (our LinkedIn integration partner) → WarmySender. Unipile delivers the acceptance to us via a webhook.
Most webhooks arrive within seconds. Some take minutes. A small fraction take hours, usually because of timing on LinkedIn's side or transient delivery issues. We have no control over how fast LinkedIn fires the original event.
To catch any acceptance the webhook missed, WarmySender polls each connected LinkedIn account every 6 hours and reconciles the relations list. If a webhook was dropped, polling catches it within the same day. The acceptance gets stamped with the actual time and your dashboard updates.
You send 50 invites at 10:00 Monday. By the end of Tuesday, your dashboard might show 0% acceptance — even if 8 people have actually accepted. This is normal. By end of Wednesday or Thursday, those 8 acceptances will appear, either via webhook or via the 6-hour poll.
If your dashboard shows 0% acceptance for more than 72 hours AND you've sent invites in that window, contact us at hello@warmysender.com. Our system pages on webhook outages within 30 minutes — but please reach out anyway, because there are individual edge cases that don't trigger the platform-wide alert.
Especially in the first 24 hours after launch, a 0% acceptance rate does not mean your campaign is broken. LinkedIn invites typically take 1 to 3 days for the first wave to come in. We surface a tooltip on the dashboard to make this clear once the campaign card has invites but no acceptances yet.
LinkedIn occasionally requires re-authentication for security reasons (suspicious activity, password change, 2FA reset, idle session, IP region change). When that happens, our integration partner Unipile reports the account as disconnected and we pause your LinkedIn campaigns automatically.
Pausing on disconnect is safety, not failure. Sending while the account is in a half-broken state is exactly how LinkedIn detects automation and restricts accounts.
When your account reconnects, all paused-by-disconnect campaigns resume automatically on the next scheduler tick. Prospects waiting at any step (invite, wait_accept, message, condition) keep their place — nothing is lost. Pending follow-ups continue at their next scheduled time per your schedule and window.
The platform also resets the failure-rate window on every campaign whose account was just remapped, so a backlog of dead-account-era errors won't immediately re-pause the campaign on resume.
If your LinkedIn account stays disconnected for more than 24 hours, WarmySender sends you an email titled "Your LinkedIn account [Name] disconnected — paused N campaigns". The email includes a one-click reconnect link.
If the disconnect is short (you reconnect within a few hours), no email is sent — the campaigns simply resume.
If the disconnect happened because your LinkedIn add-on seat was canceled, the reconnect flow routes you to Billing instead. Add a seat back, and the existing campaigns and audiences stay intact.
Still stuck? Email hello@warmysender.com with your campaign name and the day you're asking about — we'll dig into the specific row rather than a general "0 sends" symptom.
