If LinkedIn connection requests aren't sending, it's it's almost always for one of two reasons:
Your LinkedIn is disconnected (reconnect it here)
You've hit your weekly connection limit.
Paid / Active LinkedIn Accounts
80–100 invitations per day
~200 invitations per week
Includes a message up to 300 characters
Free LinkedIn Accounts
~5 invitations per month with a note (200 characters max)
~150 invitations per week without a note
Follow this quick check:
Open LinkedIn in your browser
Try sending a connection request manually
Test both:
With a message
Without a message
If it fails → it’s a LinkedIn restriction
If it works → review your LeadLoft playbook setup
