LinkedIn limits — what you need to know

• LinkedIn sets various types of limits and may temporarily restrict accounts in the event of conspicuous behaviour; some restrictions typically last for about a week. LinkedIn

• LinkedIn does not always publish official, fixed daily limits — therefore, the figures recommended here are considered practical guidelines based on industry monitoring.

What types of limits exist?

• Connection requests / Invitations: LinkedIn limits the number of invitations you can send in a given period; exceeding this limit may result in a temporary suspension.

• Direct messages to 1st-degree contacts (Messages): There is no officially published daily limit for messages to existing contacts, but platform monitoring recommends conservative upper limits to minimise risk. We limit this to +100 messages per day (varying randomly each day), for example. 

• InMail (messages to non-contacts): The number per month clearly depends on your premium plan — credits are renewed monthly. (LinkedIn ) At Outreach Master, we do not currently support InMail messages.
• Profile/view limits & network size: There are limits on profile views and a maximum number of 1st-degree connections (30,000). In practice, however, this limit is often irrelevant (LinkedIn).
• API/automation controls & suspicious activity: LinkedIn checks for automation patterns (high frequency, similar content, low acceptance rate) and may restrict accounts; however, our system ensures that these limits cannot be reached. 

Practical guidelines (safe defaults)

These recommendations are based on aggregated observations from the industry — however, LinkedIn may respond more strictly or more leniently on an individual basis. If you are unsure, start slowly (gradual warm-up).

• Connection requests: ~15–25 per day (≈100 per week for many free accounts). For sales/recruiter products, the safe weekly limit may be higher (up to ~200+ for well-aged accounts).
  
  Outreach Master usually sends a maximum of ~20 requests per day. The number varies per day in order to simulate human behaviour as closely as possible.
• Direct Messages to 1st Degree: ≤100–150 per day (depending on account age & activity, it is better to start at the lower end).
  
  Outreach Master usually sends a maximum of ~100 requests per day.
• InMails: Use the credits from your plan; you can find InMail quotas and rules in your premium subscription.
  
  Outreach Master does not yet offer this functionality.
• Profile views: For free accounts, experts recommend not relying on massive daily profile viewing — vary your actions to avoid patterns.
  
  Outreach Master does not yet explicitly offer this functionality.

Why the limits vary (what LinkedIn evaluates)

LinkedIn not only adjusts the permitted activity to a general limit, but also evaluates, among other things:

• Account age & history (older, ‘trusted’ accounts have more leeway).
• Acceptance rate of your invitations (low rates increase your risk score).
• Homogeneity of content (identical mass messages are risky).
• Sudden spikes in activity (large sudden volumes are more likely to raise alarm bells).

Best practices — how to scale safely

• Warm-up: Start new accounts gradually (start with just a few actions per day, then increase).

• Throttle & randomise: Spread out instead of ‘bursting’; random breaks and different times of day avoid patterns.

• Personalisation > volume: Higher acceptance/reply rates reduce risk.

• Monitor acceptance rate: if many invitations are rejected or ignored, throttle the volume.

• Do not use unauthorised automation tools (risky for account suspension) - Outreach Master is safe.

• Split traffic/multiple senders only with governance: if multiple accounts are used, ensure clear ownership, limits and quality assurance.

What to do if an account has been restricted?

• Read the LinkedIn notice: LinkedIn usually displays a message (‘Invitation limit reached’, etc.) and the restriction often lasts for ~1 week.
• Slow down activity / take a break: Immediately send fewer messages or none at all.
• Improve quality: Review message templates, reduce mass patterns and increase personalisation.
• Contact support: If you think the restriction is a mistake, contact LinkedIn Support via the Help section.
• Account health documentation: Make a note of what actions were taken immediately before the suspension (volume, template, tool) to learn from when upgrading.

Monitoring & Alerts (useful for teams)

• Track acceptance rate (invitations accepted/sent) daily.
• Alert in case of spike (e.g. >20% increase in daily volume compared to 7-day average).
• Log Templates & Variants — ensure that every automation is logged with a template ID and personalisation level.
• Rate Limit Backoff: Automatically use exponential backoff in case of 429/blocked responses from LinkedIn.
