Senders are real people’s LinkedIn accounts and mailboxes, so every outbound action is limited. The limits are enforced by the database for everyone, including admins, the Claude connector and the ChatGPT plugin. You can lower a sender’s limits, but nobody can raise them above the platform ceiling. The ceilings are set below what LinkedIn, Instagram, WhatsApp and the email providers tolerate. Channel Limits & Restrictions explains each network’s own rules.

​
How much a sender sends each day

Each sender has a daily limit (a cap) for each type of action. The cap is worked out fresh every day:
1

Take the lowest limit

The lowest of the platform ceiling, the warm-up level cap, and any manual cap you set.
2

Adjust for health

Multiply by ×1 at health 70 or above, ×0.6 from 50 to 69, and ×0 below 50 (the sender is paused).
3

Vary it slightly

Vary it by ±10% so the volume isn’t identical every day. It’s never below 1 if the base cap is at least 1.
4

Apply the schedule and weekly limit

Days with no working hours get a cap of 0. Invitations also stop once the 150-per-week limit is used up (weeks start on Monday).
You can see today’s used, reserved and cap figures on each sender’s Budgets tab.
Replies you send from the Inbox don’t count against any cap.

​
Platform ceilings

These are the most any sender can do per day, whatever its level or settings. Post fetches cover every time we read someone’s posts: a like step, a comment step, an AI draft that mentions a post, and profile enrichment that needs posts. Reading posts is a separate allowance from profile views, so enriching a lead’s posts never eats into profile views.
Every LinkedIn call the platform makes passes through one of these budgets. There is no back door and no setting that turns one off.

​
Warm-up levels

A new sender starts slow and earns higher limits by staying healthy.
  • LinkedIn senders start at level 0. Mailboxes start at level 3.
  • A sender goes up one level after 14 days in a row at health 85 or above.
  • LinkedIn accounts with fewer than 150 connections (or an unknown count) stay at level 0 for at least 28 days.
  • Profile edits from Profile Studio are 0 at level 0 and 1 per day from level 1 up.
  • A sender whose profile quality score has a critical failure (no real photo, or fewer than 150 connections) doesn’t move up a level until it’s fixed.
Free (non-Premium) LinkedIn accounts never go above level 1. Only Premium LinkedIn accounts and mailboxes can reach level 5. Free accounts also have a small monthly allowance of invitations with a note.

​
Working hours

Actions only run inside each sender’s working hours, in the sender’s own timezone. The default is Monday–Friday, 09:00–18:00. Every action is given a random time within those hours, so nothing goes out on a round minute or in a burst. Each night the planner schedules the next day’s actions for each sender. During working hours it also tops up the rest of today every 20 minutes, so newly enrolled leads start within about 20 minutes. To skip that wait, use Schedule today’s actions on the sender’s Overview tab. Change working hours on the sender’s Schedule tab.

​
Health score

Each sender has a health score from 0 to 100. It’s the lowest of six sub-scores, so one weak area pulls the whole score down. Health is recalculated every hour, and again soon after events like a disconnect or a rejected action.

​
Automatic pauses

​
Two more guards

InMail speed. LinkedIn has restricted accounts that jumped from a few InMails a day to many, even with credits left. Week-over-week InMail growth is therefore capped at about 50% above the previous week’s daily average. You’ll see InMails pace up over a few weeks rather than all at once. Background enrichment. Filling in profiles for leads that aren’t in a sequence uses only the profile views left over after the day’s sequence actions, at most 30% of the sender’s allowance, and none at all at warm-up levels 0 and 1. Campaigns always come first.

​
Where to see these rules in the app

Open a sender and go to its Budgets tab. It shows, for each action, the platform ceiling, the cap for the sender’s current warm-up level and any manual cap, so you can see the limit that applies today and lower it. Settings → Safety lists the manual caps your team has set on every sender, with a Budgets → link for each, and explains the consent rules for WhatsApp and Instagram. Everyone in the workspace can view it.
