Connection Request on LinkedIn is an invitation sent to another member to join your first-degree network. When accepted, both parties can message each other for free, see each other’s updates in their feed, and appear as mutual connections to others. For B2B sales and marketing, connection requests are the first step in a LinkedIn outreach sequence. Personalized connection notes (up to 300 characters) significantly improve acceptance rates compared to blank requests. LinkedIn limits users to approximately 100 connection requests per week, making targeting and personalization critical. After connecting, following up within 24-48 hours with a non-sales message maintains momentum without triggering spam filters.
