On LinkedIn, your connection degree determines what you can see, who you can message, and how warm your outreach will land. The difference between a 1st and a 3rd connection isn't just a label — it controls profile visibility, direct messaging access, and how much social proof you can use to open a conversation. For SDRs building pipeline from LinkedIn, this matters every single day.
- 1st connections are people you've directly connected with — you can message them freely. 2nd and 3rd connections have progressively less visibility and fewer contact options.
- 2nd-degree prospects are the highest-value cold targets: you can reference a shared connection, which meaningfully increases reply rates.
- Strategically growing your 1st-degree network is the cheapest way to expand the number of 2nd-degree prospects you can reach without a paid tool.
- LinkedIn Sales Navigator largely removes degree-of-connection friction — you can search and InMail prospects regardless of where they sit in your network.
- Understanding connection levels helps you prioritise your outreach queue: start with 2nd-degree, warm up 3rd-degree through mutual connections before cold-messaging.
What do 1st, 2nd, and 3rd connections actually mean on LinkedIn?
LinkedIn uses a degree-of-connection model borrowed from the concept of six degrees of separation. Every person on the platform is classified relative to you based on how many steps it takes to connect you through mutual connections.
1st-degree connections
These are people who have accepted your connection request, or whose request you've accepted. You're directly linked. You can message them for free using LinkedIn's standard messaging, see their full profile, and interact with all of their activity. Think of these as your LinkedIn contacts.
2nd-degree connections
These are people who are connected to at least one of your 1st-degree connections. You aren't directly linked, but you share a mutual contact. LinkedIn shows you the number of shared connections and, in most cases, who those people are. You can send a connection request with a note, but you can't message them directly without connecting first — unless you have InMail credits.
3rd-degree connections (and 3rd+)
These are people connected to your 2nd-degree connections — one further step removed. You likely share no direct mutual connections. LinkedIn typically shows only their first name, last initial, and a partial headline. The label "3rd+" means the person is three or more degrees away. At this distance, LinkedIn's free tier gives you almost no information and no direct messaging access.
Out of network
Some profiles are set to completely private, or the person has restricted visibility so aggressively that not even their name is fully visible. These appear as "LinkedIn Member" with no identifiable detail. You cannot contact them through standard means at all.
What profile information can you see at each connection degree?
The practical difference between connection degrees shows up most in what data is accessible. This directly affects how much context you can gather before reaching out.
| Connection level | Full name | Headline | Current company | Work history | Mutual connections | Direct message |
|---|---|---|---|---|---|---|
| 1st | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ (free) |
| 2nd | ✓ | ✓ | ✓ | ✓ (usually) | ✓ | Connection request only |
| 3rd / 3rd+ | First name + last initial | Partial | Sometimes | ✗ | ✗ | InMail only |
| Out of network | "LinkedIn Member" | ✗ | ✗ | ✗ | ✗ | ✗ |
One important nuance: users control their own privacy settings. A 2nd-degree connection who has locked down their profile may show less information than the table above suggests. Conversely, some 3rd-degree profiles are set to "open," which means you can see their full profile and even message them without InMail credits.
How do you contact a 2nd or 3rd connection on LinkedIn?
Your options depend on the degree and whether you're using a free or paid LinkedIn account. Here are the four practical routes, in order of effectiveness for cold outreach.
1. Send a connection request with a personalised note (2nd degree)
This is your primary tool for 2nd-degree prospects on a free account. You get 300 characters for the note — enough to mention a shared connection, a specific reason you're reaching out, or a relevant observation about their work. Personalised connection requests are accepted at a significantly higher rate than blank requests. Salesloft's outreach data consistently shows that mentioning a mutual connection in the note is one of the highest-leverage personalisation tactics available at no cost.
2. Ask a mutual connection for an introduction (2nd or 3rd degree)
If you share a strong 1st-degree connection with the prospect, a warm introduction still outperforms cold outreach by a wide margin. This doesn't scale, but for high-value accounts it's worth the ask. The shared connection data LinkedIn surfaces for 2nd-degree profiles makes identifying these opportunities straightforward.
3. InMail credits (any degree, requires Premium or Sales Navigator)
InMail lets you message anyone on LinkedIn regardless of connection status. Premium accounts include a fixed number of InMail credits per month (typically 5–15). Sales Navigator includes more credits and lets you send InMails to any profile. The catch: InMail open rates vary widely, and many prospects treat them as spam unless the message is highly relevant and specific.
4. Find contact details off-platform
For 3rd-degree prospects where LinkedIn access is limited, many SDRs use LinkedIn as the discovery layer — identifying the person — then find their work email through a tool like Apollo, Hunter, or Clay to make first contact via email instead. This sidesteps the connection-degree problem entirely.
Why do LinkedIn connection degrees matter for B2B sales?
Connection degrees directly shape the quality and warmth of your outreach, which in turn affects reply rates. This is not a minor variable.
"The single biggest predictor of cold LinkedIn message reply rates isn't the copy — it's whether the sender and recipient share a mutual connection. Warm paths convert at 3–5x the rate of fully cold approaches, even with identical messaging."
— Becc Holland, Founder, Flip the Script (LinkedIn outreach methodology, 2023)
For SDRs, this has a direct implication: prioritise 2nd-degree prospects over 3rd-degree wherever your ICP allows. When you reach out to a 2nd-degree connection and mention the shared contact, you're no longer a stranger — you're one reference away from being a known quantity. That changes the psychological calculus for the prospect completely.
Connection degree also affects list-building. LinkedIn's own data on the Social Selling Index shows that sales professionals with SSI scores above 70 — which correlates heavily with network depth and activity — generate 45% more opportunities than those with lower scores. A larger 1st-degree network means a larger 2nd-degree pool, which means more warm-path prospects available at any given time.
There's also a data access angle. When you're building a prospect list and need to verify a title, confirm a company, or check a recent job change, 2nd-degree profiles give you full visibility. 3rd-degree profiles often don't. If your prospecting workflow relies on LinkedIn profile data, a 3rd-degree-heavy target list creates gaps that slow you down.
This is where tools that work alongside LinkedIn become valuable. If you're targeting companies based on competitor usage — for example, identifying businesses that currently use a rival product — a tool like Stealery lets you build that list first (by competitor, company size, location, and hiring signals), and then you layer in LinkedIn to identify the right contacts and their connection degree. You're not starting from LinkedIn and hoping the prospect is reachable — you're starting from intent data and working backwards to the warmest contact path available.
How do you expand your LinkedIn network reach for prospecting?
Expanding your reach is a compounding game. Every new 1st-degree connection converts that person's entire network into your 2nd-degree pool. The math is significant: a LinkedIn user with 500 connections who is well-connected in your ICP can unlock thousands of new 2nd-degree prospects in a single click.
Connect strategically, not randomly
Random network growth doesn't help your prospecting. You want 1st-degree connections who are embedded in your ICP — VPs of Sales at SaaS companies, RevOps leaders, founders in your target segment. When you connect with these people, their networks become your 2nd-degree pool. Target connectors, not just buyers.
Engage before you outreach
Commenting on a 2nd or 3rd-degree prospect's posts before sending a connection request is a documented warm-up tactic. It creates a name-recognition moment: when your connection request lands, they've seen you before. It doesn't take long — two or three substantive comments over a week is enough. This is especially effective for 3rd-degree targets where you have no mutual connection to reference.
Use LinkedIn events and groups
Members of the same LinkedIn Group or attendees of the same LinkedIn Event are technically reachable with a free message, regardless of connection degree, depending on group settings. Joining industry groups relevant to your ICP is a legitimate way to expand your messaging reach without using InMail credits.
Ask your team to map shared connections
If your target account is a 3rd-degree connection for you but a 2nd-degree connection for a colleague, that colleague can make the introduction or send the connection request instead. In teams with shared accounts lists, this kind of network triangulation is an underused tactic that requires zero budget.
How does LinkedIn Sales Navigator change what connection degrees mean?
Sales Navigator substantially reduces the practical friction of connection degrees. It doesn't eliminate them, but it changes the calculation for high-volume prospecting teams.
With Sales Navigator, you can search the entire LinkedIn network — not just your 1st and 2nd-degree connections — using detailed filters: seniority, company size, geography, technology used, job changes in the last 90 days, and more. You see full profiles regardless of connection degree. You can save leads and accounts, receive alerts when prospects change jobs or get promoted, and send InMails to anyone with an active profile.
That said, Sales Navigator doesn't make cold outreach warm. The underlying social proof advantage of a shared connection still applies. What Sales Navigator does is expand your reachable universe and give you the data to personalise effectively even for 3rd-degree targets — so you can compensate for the lack of a warm path with stronger relevance in the message itself.
For SDRs working a defined ICP, the practical workflow looks like this: use Sales Navigator to identify and research 3rd-degree prospects, find a relevant trigger (job change, company funding, tech stack signal), and open with that context rather than a generic intro. The connection degree is less of a barrier when the message itself makes clear why you're reaching out right now.
One benchmark worth knowing: LinkedIn's internal data on Sales Navigator users shows they connect with 3.1x more decision-makers per quarter compared to free-account users working the same ICP. The degree-of-connection constraint is real, but it's a solvable problem with the right tooling and the right outreach strategy.
