When using LinkedIn automation tools like lemlist, it's important to understand LinkedIn's platform policies and restrictions. This article explains common LinkedIn account situations, how to troubleshoot them, and best practices for staying within LinkedIn's guidelines while using third-party integration tools.
Common LinkedIn Platform Restrictions and Policies
1. Account Disconnections
LinkedIn sessions may expire or disconnect from third-party tools due to:
Manual logout from LinkedIn or your automation platform
Browser cookie clearing, which removes authentication sessions
LinkedIn's security protocols require periodic re-authentication
Browser updates or cookie expiration
2. LinkedIn's Invitation Policies
LinkedIn maintains strict invitation limits as part of its platform policies:
LinkedIn restricts the number of invitations users can send to prevent spam — the observed ceiling is roughly 100 invitations per rolling week
The platform monitors invitation acceptance rates and may limit accounts with many pending or ignored invitations
These limits apply to all LinkedIn activity, whether manual or through any third-party tool
Custom invitation notes (personalized messages attached to connection requests) are limited to 3 per month on free LinkedIn accounts. Once this quota is reached, LinkedIn will block custom-noted invites until the next monthly reset. LinkedIn Premium and Sales Navigator accounts have no monthly cap on personalized invites. Standard invites without a note are not affected by this cap on any plan.
3. LinkedIn Account Restrictions
LinkedIn may restrict accounts based on its platform policies when detecting:
Unusual activity patterns that violate their user agreement
Multiple authentication attempts from different sources
Activity that LinkedIn's algorithms flag as potentially fraudulent
Warning signs from LinkedIn:
A message saying you are sending too many invitations, or invitations blocked for the week
CAPTCHA, identity or phone verification requests
Unexpected logouts, repeated disconnections from lemlist, or a sudden drop in acceptance rate
Troubleshooting LinkedIn Connection Issues
1. Re-establishing Connections
When LinkedIn requires re-authentication:
Log into LinkedIn directly through your browser
Re-authenticate your connection through the Chrome extension
Refresh your LinkedIn session if needed
Clear and reset browser cookies if connection issues persist
2. Working Within LinkedIn's Invitation Limits
To stay compliant with LinkedIn's policies:
LinkedIn typically lifts temporary restrictions automatically after one week
Withdraw pending invitations after 7–14 days to improve your acceptance rate
Follow LinkedIn's recommended outreach practices
On a free LinkedIn account, reserve your 3 monthly custom invitations for highest-priority prospects and use standard invites for all other outreach. Premium and Sales Navigator accounts have no monthly cap here.
3. Addressing Platform Restrictions
For LinkedIn-imposed restrictions:
Temporary Limits: LinkedIn usually lifts these after a cooling-off period (typically one week to one month)
Platform Bans: Contact LinkedIn support directly, as third-party tools cannot influence LinkedIn's restriction decisions
Cooldown and Gradual Warm-up Plan: Pause all LinkedIn steps for at least 48 hours and keep logging in and engaging by hand. Restart very low, around 5 actions per day, mostly soft actions (profile visits, follows, likes). Increase week by week only if no new warning appears, with a small ramp-up step. Fix the cause shown by the LinkedIn Health Score (beta) in Settings → Deliverability Hub → LinkedIn: volume, acceptance, mix or pending invitations.
The very low volume in this section — around 5 actions per day — is a recovery number for an account that has already been restricted, not a normal operating limit. For a healthy account, see the standard recommendations in Set account limits: 20 invites/day, 30 visits/day, 30 messages/day, and 100 actions/day maximum across all types.
Best Practices for LinkedIn Compliance
Respect LinkedIn's Limits: On a healthy account, stay within the recommended daily limits and remember that invitations are capped at roughly 100 per rolling week. While recovering from a restriction, drop to around 5 actions per day, mostly soft actions, and build back up week by week.
Maintain Account Integrity: Use one lemlist seat per LinkedIn profile and one Chrome profile per LinkedIn account. Never switch LinkedIn accounts inside the same Chrome profile, and don't share the account.
Keep Sessions Active: Maintain consistent login sessions to avoid re-authentication issues. Logging out or clearing cookies disconnects LinkedIn from lemlist.
Follow LinkedIn's Terms: Review and comply with LinkedIn's User Agreement
Count Manual Outreach in Your Limits: Invitations and messages you send by hand count against the same LinkedIn quota, and lemlist does not see them. If you prospect by hand too, lower lemlist's limits accordingly. Don't run another automation tool on the same LinkedIn account. Manual engagement (posts, comments, replies) is fine.
FAQs
Can third-party tools remove LinkedIn restrictions? No, only LinkedIn controls their platform restrictions. Contact LinkedIn support for restriction-related issues.
How long do LinkedIn restrictions typically last? LinkedIn's temporary restrictions usually resolve within a week, though some may extend up to a month depending on the violation type. For a faster recovery, pause all LinkedIn steps for at least 48 hours before gradually resuming with very limited actions, and contact LinkedIn support for guidance if restrictions persist beyond a month.
