• Completely free for all LinkedIn users
• Limited to 1st-degree connections only
• No subject lines - conversation starts immediately
• Unlimited sending with no credit system

Response Rate Comparison

According to SalesRobot's analysis:

Regular Message Response Rates

Context	Response Rate
Warm connection (engaged with content)	35-50%
Recent connection (within 30 days)	25-35%
Cold connection (no prior engagement)	15-25%

InMail Response Rates

Context	Response Rate
Personalized InMail	15-25%
Template InMail	8-12%

The pattern is clear: Prior relationship and context dramatically improve response rates regardless of message type.

When to Use InMail

According to LinkedFusion's guide, InMail makes sense for specific situations:

High-Value Prospects Outside Your Network

InMail is designed for reaching decision-makers who rarely accept connection requests:

• C-suite executives
• Industry influencers
• Hiring managers
• Strategic partnership targets

Time-Sensitive Opportunities

When you cannot wait for connection acceptance:

• Event follow-ups within 24-48 hours
• Job applications requiring immediate attention
• Limited-time offers or invitations
• Breaking news relevant to the prospect

Formal Sales Outreach

InMail's subject line and longer format suit:

• Complex value propositions
• Partnership proposals
• Enterprise sales introductions
• Recruitment outreach

When to Use Regular Messages

According to LinkedHelper's analysis:

Nurturing Existing Connections

Regular messages excel for relationship building:

• Following up after events or meetings
• Sharing relevant content or articles
• Congratulating achievements
• Checking in on ongoing conversations

Warm Outreach After Engagement

When prospects have already interacted with you:

• Responded to your content
• Viewed your profile
• Engaged with your posts
• Accepted your connection request

Cost-Effective Communication

With unlimited free messages:

• No reason to waste InMail credits on connections
• Better for ongoing conversations
• Ideal for long-term relationship nurturing

What Most Guides Get Wrong

Most InMail vs message comparisons focus entirely on tactical optimization—subject lines, character counts, personalization formulas—without addressing the fundamental problem: cold outreach generates poor conversion rates regardless of format.

The Response Rate Illusion

A 25-35% response rate on messages sounds impressive until you consider what happens next:

• Many responses are polite declines
• Positive responses require extensive follow-up
• Conversion to meetings is typically 10-20% of responses
• Deals closed from cold outreach average 1.7%

According to HubSpot, outbound leads close at just 1.7% compared to 14.6% for inbound—an 8.6X difference that no message optimization can overcome.

The Inbound Alternative

When prospects message you first, the entire dynamic changes:

Metric	Cold Outreach	Inbound Conversation
Response rate	15-35%	100% (they initiated)
Positive intent	10-30%	70%+
Meeting conversion	10-20%	40-60%
Close rate	1.7%	14.6%

Building LinkedIn authority that attracts inbound conversations transforms both InMail and regular message effectiveness.

How Authority Improves Both Message Types

When you have established LinkedIn authority, your outreach transforms:

For Regular Messages

• Connections already recognize your name
• Prior content engagement provides context
• Higher response rates from warm relationships
• Easier conversation starters

For InMail

• Subject lines reference shared content engagement
• Recipients have seen your expertise
• Higher open rates from name recognition
• Better response rates from established credibility

Real Example

Cold InMail (no authority):

Subject: Quick question about your sales process Hi [Name], I noticed you're VP of Sales at [Company]. We help companies like yours...

Authority-backed InMail:

Subject: Loved your comment on my demand gen post Hi [Name], Your insight about attribution modeling in my LinkedIn post yesterday was spot-on. I'd love to continue that conversation...

The second approach leverages prior engagement to transform cold outreach into warm conversation.
