Oskar Moen from Sendpilot answered another user on March 10, 2026 and said LinkedIn controls the limit for connection notes — free accounts typically can add notes to about 5 connection requests per month, while LinkedIn Premium or Sales Navigator lets you include notes on all requests. Sendpilot respects those limits: once you hit the connection-note limit, Sendpilot will keep sending connection requests without a note so your activity stays within LinkedIn’s rules.
