10 Best LinkedIn Tools for Sending Mass InMails in 2025
LinkedIn InMail is a powerful feature that allows you to message LinkedIn members who aren't in your network, making it invaluable for recruiting, sales prospecting, and business development. However, manually sending InMails one by one is time-consuming and inefficient when you're reaching out to hundreds of qualified leads.
InMail automation tools can help you scale your outreach efforts, but choosing the right tool requires careful consideration of pricing, features, security, and LinkedIn compliance. In this comprehensive guide, we'll explore the 10 best LinkedIn tools for sending mass InMails in 2025, comparing their capabilities to help you make an informed decision.
Important Disclaimer: LinkedIn enforces strict limits on InMail usage and considers some forms of automation to be violations of their terms of service. Always use InMail automation tools responsibly, personalize your messages, respect credit limits, and monitor your account for any restrictions. The safest approach is to use official LinkedIn tools or solutions that prioritize account safety.

Understanding LinkedIn InMail: What You Need to Know
Before investing in any InMail automation tool, it's crucial to understand how LinkedIn InMail works:
What is LinkedIn InMail?
InMail is a LinkedIn feature that allows you to send messages to LinkedIn members who aren't in your network. It's available with:
- LinkedIn Premium accounts (limited InMails per month)
- Sales Navigator subscriptions (20-50 InMails per month)
- LinkedIn Recruiter accounts (significant InMail credits)
InMail Credit System
Most LinkedIn plans provide a monthly allocation of InMail credits:
- Each InMail message costs 1 credit
- If the recipient responds within 90 days, you get your credit back
- Unused credits typically don't roll over month to month
- Credit limits vary by subscription tier
InMail vs Regular Messages
- InMail: Can reach anyone on LinkedIn (requires credits)
- Regular Messages: Only for your connections (free, no credits needed)
- Open Profiles: Some members allow free messages without connection
Important Risks & Compliance Considerations
LinkedIn's Terms of Service
LinkedIn's User Agreement prohibits unauthorized automations, bots, or tools that automate messaging at scale. Many third-party automation tools may violate these terms, potentially leading to:
- Account warnings or restrictions
- Temporary feature limitations
- Permanent account suspension
- Loss of InMail credits
Official vs Third-Party Tools
Official Tools (Safest):
- LinkedIn Recruiter
- LinkedIn Sales Navigator
- No risk of TOS violations
- Most expensive options
Third-Party Tools (Higher Risk):
- Bindago, Expandi, Zopto, etc.
- More affordable
- Risk of detection
- Require careful, responsible use
Reducing Risk When Using Automation
If you choose to use third-party automation tools:
- Start slowly - Don't send maximum volume immediately
- Personalize heavily - Use recipient names, company details, relevant context
- Respect limits - Don't exceed your InMail credit allocation
- Use delays - Space out messages with natural, random intervals
- Monitor closely - Watch for warnings or unusual account behavior
- Quality over quantity - Target highly relevant prospects only
- Choose secure tools - Prefer desktop apps (like Bindago) that keep credentials local
Best Practices for Mass InMail Campaigns
1. Targeting & List Building
- Use Sales Navigator's advanced filters to build highly targeted lead lists
- Focus on prospects matching your ideal customer profile
- Verify that prospects are decision-makers in their organizations
- Segment lists by industry, role, company size, or other relevant criteria
2. Message Personalization
Personalized InMails have significantly higher response rates:
- Use the recipient's name - Always include {firstName} or {fullName}
- Reference their company - Mention {companyName} to show relevance
- Acknowledge their role - Reference their {title} or expertise
- Add context - Mention recent posts, company news, or mutual connections
- Keep it concise - 75-100 words is optimal for InMail messages
3. Compelling Subject Lines
Your InMail subject line determines whether messages get opened:
- Keep it under 50 characters
- Make it benefit-focused or curiosity-inducing
- Personalize when possible
- Avoid spam triggers (FREE, ACT NOW, etc.)
- Test different approaches
4. Message Structure
Effective InMail messages follow this structure:
Opening: Personalized greeting + credibility or connection
Value Proposition: Clear benefit or reason for reaching out
Call to Action: Specific, low-commitment next step
Signature: Professional closing with contact information
5. Follow-Up Strategy
- Wait 5-7 days before first follow-up
- Maximum 2-3 follow-ups total
- Add new value in each follow-up
- Know when to stop (respect "not interested" signals)
6. Tracking & Optimization
Monitor these metrics:
- Open rate (aim for 40-50%)
- Response rate (aim for 10-15%)
- Positive response rate (aim for 5-8%)
- Meeting booking rate (aim for 2-5%)
Continuously test and optimize:
- Subject lines
- Message length
- Call to action
- Sending times
- Personalization variables
