What is LinkedIn warmup and how do I turn it on?

LinkedIn warmup runs your connected LinkedIn account the way an active person would: viewing profiles, reacting to posts, writing comments, publishing the odd post, and sending a few connection requests, spread across your working hours. A brand-new or long-dormant account that suddenly sends lots of invitations looks automated and gets restricted. Warmup builds the activity first, and outreach shares the same daily budget.

It is different from email warmup. There is no peer network and no other Warmerly users involved. Everything happens on your own LinkedIn account. See How warmup works for the email side.

Warmup is off by default. When you connect an account, its warmup starts paused. You switch it on yourself.

Turn it on

1. Open Accounts and the LinkedIn tab.
2. On the account, expand LinkedIn warmup settings.
3. Switch on Run warmup automatically. This saves immediately.
4. Fill in the fields below so the posts and comments sound like you, then save.

The fields:

• Post and comment guidelines: your voice, audience, offers, and topics to avoid.
• Topics: comma separated, for example "cold email, deliverability".
• Industries: comma separated.

Warmerly writes posts and comments with AI from those settings, and searches posts and people in your topics and industries to react to and connect with. The more specific the topics, the better the activity fits your profile.

What it does each day

Once a day, inside the account's send window and timezone, Warmerly plans a set of actions and spaces them out through the day with some random spread:

• publishes an original post
• reacts to posts in your topics
• comments on posts in your topics
• views profiles of people in your topics
• sends connection requests to a few of those people

At full pace the caps are up to 40 profile views, 20 reactions, 5 comments and 2 posts a day, plus the connection request limits described in How do I connect LinkedIn.

How the ramp works

Volume starts small and rises as warmup days accumulate: about a fifth of full pace for the first 3 days, then roughly a third, about half, three quarters, and full pace from about day 22. A day counts when warmup actually ran on it, so days when warmup was off or paused do not move the ramp forward.

Campaign steps on the same account draw from the same daily budget. Outreach can never push the account past what warmup has earned.

Caps can only be lowered, never raised past the safe maximums.

When warmup pauses itself

If LinkedIn reports a restriction, a checkpoint, a rate limit or an invalid session, Warmerly pauses warmup on that account as a safety step. To resume, first fix the cause (for example reconnect the account, see LinkedIn outreach), then switch Run warmup automatically on again.

Warmup also does not run when:

• the account is Disconnected
• its slot is past due, or has ended
• your workspace is billing-locked or suspended

If the AI writing step returns nothing for a post or comment, that one action is skipped and the rest of the day carries on.

Common problems

• Nothing is happening on my account. Check that Run warmup automatically is on, the account is Active, and the slot is paid up. Actions are planned for the account's working-hours window, so the first ones do not appear instantly.
• I turned it on, but posts do not match my business. Add specific guidelines, topics and industries and save. The changes apply to the next planned day.
• Can I run warmup without the paid slot? No. Warmup and sending both need a slot. See Channel accounts: paid slots and overage.
• Does warmup guarantee my account will not be restricted? No. It lowers the risk by keeping behaviour human-like and inside safe limits. LinkedIn decides what counts as a violation.
