You’ve just scouted the perfect candidate on LinkedIn. The profile is a match, the timing seems right. Now comes the tactical move: how do you break the ice? Should you burn a precious InMail credit to guarantee visibility? Send a "blank" invitation to spark curiosity? Or bet on an ultra-personalized note to show you’ve done your homework?
As recruitment experts, we see too many teams stuck in one method out of habit. However, peak performance lies in psychology and resource management. Here is the verdict of the triple match.
1. InMails vs. Connection Requests: What is the difference?
Before diving into the analysis, let's clarify the technical ground. When you are trying to reach someone new on LinkedIn, you are essentially choosing between a digital handshake and a priority letter. While both aim to start a conversation, they function quite differently regarding access and etiquette.
The Connection Request is the standard, free method available to every user. It is an invitation to join someone’s professional network. If they accept, you become "1st-degree connections," allowing you to message freely and see full profile details. However, this method comes with strict limitations. You must wait for the recipient to accept your request before you can send a full message, and your initial introductory note is capped at 300 characters. You can also leave it blank.
The InMail, by contrast, is a premium feature available only to subscribers of LinkedIn Premium, Sales Navigator, or Recruiter. Think of this as a direct line that bypasses the gatekeeper. An InMail allows you to message someone you are not connected with, landing directly in their inbox without needing a prior acceptance. You can include dedicated subject line and up to 2,000 characters in the body.

2. Why Recruiters Default to InMails (The LinkedIn Trap)
LinkedIn heavily encourages the use of InMails. From the platform's perspective, this makes perfect sense, and they have built features that make the InMail the path of least resistance for hiring teams.
- The "Inbox Certainty": You are guaranteed to land in the candidate's main inbox without waiting for an approval. When a recruiter sends an InMail, they are essentially purchasing the guarantee that their message will land directly in the candidate's main inbox without the friction of a gatekeeper.
- Unlimited Characters: Unlike connection notes, InMails allow for long-form pitches, attachments, and structured job offers.
- Platform Nudging: LinkedIn Recruiter is designed to make sending an InMail the "path of least resistance."
3. The 5 Major Limitations of InMails
While they seem like a "silver bullet," InMails have significant drawbacks that can hurt your ROI:
- Strict Limits: You only get a fixed number of credits based on your plan. Once they are gone, you are have to wait until they recharge, or buy extra inmails.
- High Cost: At ~$2 per credit, a failed campaign is expensive (more information on our blog post: Linkedin Inmail credits cost)
- Lower Response Rates: Data shows that InMails often feel like "sponsored ads." Connection requests, being more personal, consistently yield higher engagement.
- No Network Growth: An InMail is a one-off transaction. If the candidate doesn't reply, they aren't in your network. You don't build a long-term asset.
- Single Follow-up: You can usually only send one follow-up message if the InMail goes unanswered, limiting your "nurturing" capabilities.
4. The Dashboard: Statistics and Psychology
💡 Expert Tip: "Pattern Interrupt" is your best ally. In 2026, top-tier candidates are bombarded with InMails. A text-free invitation creates mystery, often opening a door that a paid pitch would have kept shut.
5. Strategic Analysis: Comparing Your Options
Approach 1: The InMail (The Last Resort Artillery)
Use it for "out-of-network" profiles you need to reach urgently. But remember: it's a "one-shot" weapon. If they don't reply, the credit is gone, and the relationship hasn't even started. It's an expensive way to fail if your targeting isn't 100% accurate.

Approach 2: The Blank Invitation (The Curiosity Bet)
The preferred strategy for sharp headhunters who value network growth. It requires zero effort from the candidate to "Accept." Once they are in, you have direct, free access to them forever.
The Hack: Tools like Leonar detect the acceptance in real-time, allowing you to trigger a message the moment the candidate is still active on the app, maximizing the "curiosity" window.

Approach 3: The Personalized Note (The Relationship Bet)
Essential for C-Level profiles and high-stakes roles.
The Trap: It is extremely time-consuming. Real personalization takes 5-10 minutes per profile, which kills your sourcing volume.
The Solution: Platforms like Leonar automate this by using AI to analyze the profile and write a unique hook in 2 seconds, giving you the best of both worlds: quality and scale.

6. The Escalation Strategy: Only pay if the free tools fail
The best recruiters view InMails as a last resort, not a first step. An effective escalation strategy begins with a "Curiosity" phase, where you send a blank connection request. This approach is free, incredibly fast to execute, and relies on the candidate viewing your profile out of intrigue rather than reacting to a pitch.
Here are the three steps.
- Phase 1 (Curiosity): Send a blank invitation. Fast and free.
- Phase 2 (Pivot): If not accepted after 3 days, withdraw and send an Email.
- Phase 3 (Final): Use InMail only for the 5% who remain silent to all other channels.
7. Why automate with Leonar?
Managing this multi-layered strategy manually is a nightmare. Leonar acts as your orchestrator:
- Smart Workflows: Program sequences (Blank Invite → Automated Follow-up → Email → Final InMail).
- Save Budget: Cut LinkedIn costs by 4 by using free channels first.
- Build an Asset: Grow your network and centralize every reply (LinkedIn, Email, WhatsApp) in one unified inbox.
