LinkedIn limits how many connection requests and messages an account can send per day. ReachBoost enforces these limits to protect your account - and also applies its own fallback limits to prevent accidental overusage even if your campaign settings are too high. That said, you should still configure limits correctly to stay safe.

What the limits are

LinkedIn does not publish official numbers, but based on current platform behaviour:

These are per LinkedIn account, not per workspace or campaign. If you have multiple campaigns running on the same LinkedIn account, the limits are shared across all of them.

During warmup: ReachBoost automatically caps sending to warmup limits regardless of your campaign settings - you do not need to manually lower your limits during this period.

Where to configure limits in ReachBoost

Limits are set per campaign in the Settings step of the campaign wizard.

Connect requests limit per LinkedIn account - the daily range of connection requests this campaign can send per LinkedIn account (e.g. 10 to 15).

Follow-up messages limit per LinkedIn account - the daily range of follow-up messages this campaign can send per LinkedIn account (e.g. 10 to 15).

You can also view and edit these limits from the campaign detail page - open the campaign and go to the Sequence tab.

ReachBoost randomises within your range to mimic natural behaviour. Setting 10–15 means some days it sends 10, some days 13, some days 15 - never a perfectly consistent number.

Active days and active hours

Only set campaigns to run during normal business hours in your target audience's timezone. Sending at 3am or on weekends raises red flags.

You can also edit active days and active hours directly from the campaign detail page Sequence tab.

Recommended:

·        Active days: Monday to Friday

·        Active hours: 08:00-18:00 in your target timezone

Warmup and limits

If your LinkedIn account is still in warmup mode, the campaign settings page will show a warning badge next to your limits.

During warmup:

• ReachBoost warmup limits override your campaign limits automatically - no manual adjustment needed

• Avoid running too many campaigns simultaneously on the same LinkedIn account - the limits stack across campaigns

• Warmup will handle the ramp-up to full volume - you do not need to wait for 70%+ before launching a campaign

What NOT to do

·        Do not set limits above **30/day** - even if the input field allows it

·        Do not run 5+ campaigns simultaneously on one LinkedIn account - the limits stack

·        Do not turn off active hours - sending 24 hours a day is a clear automation signal

·        Do not ignore a disconnected account - if an account disconnects mid-campaign, fix it immediately rather than letting the campaign keep trying

·        Do not repeatedly reconnect accounts - this resets warmup and looks suspicious to LinkedIn

What happens if LinkedIn restricts your account

LinkedIn may ask you to verify your identity (phone number verification) or temporarily limit your account's ability to send invitations. If this happens:

1.      Stop all active campaigns on that account immediately
2.      Log in to LinkedIn directly and complete any verification steps
3.      Wait 48–72 hours before restarting any campaigns
4.      When you restart, use lower limits than before and enable warm up
