LinkedIn InMail is a direct messaging tool that helps B2B sales teams connect with decision-makers like executives and department heads. It works because it bypasses traditional gatekeepers, offers advanced targeting, and allows for highly personalized messages. To make the most of InMail, focus on these key strategies:

• Personalization is key: Reference recent activity, shared connections, or specific challenges to make your message relevant.

• Craft strong subject lines: Keep them under 50 characters and make them specific to increase open rates.

• Keep messages concise: Messages under 300 characters perform better. Focus on outcomes rather than features.

• Timing matters: Send InMails during business hours, midweek, and avoid Mondays and Fridays.

• Leverage automation and AI: Use tools to scale outreach while maintaining a personal feel.

• Track and optimize: Measure response rates, test subject lines, and adjust based on performance.

10 Simple Tips for Writing the Perfect LinkedIn InMail

Best Practices for Writing InMail Messages

Crafting InMail messages that grab attention and spark responses requires more than just sending a generic note. Success lies in creating messages that feel personal, are well-structured, and offer immediate value. The difference between being ignored and starting a meaningful conversation often comes down to the details.

How to Personalize InMail Messages

Personalization is your secret weapon for cutting through the noise. In fact, individualized InMails see a 15% higher engagement rate compared to bulk messages.

Start by referencing recent activity on LinkedIn. This simple step can increase response rates by 27%. For instance, mentioning a prospect's recent post or celebrating a career milestone shows genuine interest in their professional achievements. Tools like LinkedIn activity alerts and Sales Navigator make it easy to spot these opportunities.

Shared connections can also work in your favor. Highlighting a mutual contact or a shared professional experience adds credibility and makes your outreach feel more relevant. Just ensure the mention feels natural and authentic.

Go a step further by tailoring your message to the recipient's industry or role. Instead of addressing generic challenges, focus on specific hurdles they might face. For example, if you're reaching out to a VP of Sales at a fast-growing SaaS company, you could mention the complexities of scaling sales teams during rapid growth.

The trick is to show you've done your homework - without overstepping. A simple mention like, "I noticed your recent post about AI in sales", demonstrates effort while keeping the spotlight on the recipient.

Once you’ve nailed personalization, the next step is structuring your message in a way that captures attention.

Writing Better Subject Lines and Message Structure

Your subject line is the first thing your prospect sees, and it can make or break your message. Over 40% of users open a message based solely on the subject line. To stand out, make it specific and relevant. Instead of using vague phrases like "Quick question" or "Partnership opportunity", try something like, "Congrats on your new role - quick idea for [Company Name]" or "Thoughts on your recent [specific topic] post." Subject lines like these can achieve open rates between 38% and 55%.

While LinkedIn allows up to 200 characters for subject lines, keeping them under 50 characters ensures they’re clear and impactful, especially on mobile devices.

A strong InMail message follows a simple structure:

• Personalized greeting: Start by addressing the recipient by name and referencing something specific about them.

• Concise value proposition: Highlight how you can address a particular need or challenge they face.

• Clear call-to-action: End with a straightforward and approachable request, like, "Would you have 15 minutes to chat next week?"

Your value proposition should be specific and, if possible, measurable. For instance, instead of saying, "We help companies improve efficiency", you might say, "We help companies like yours cut onboarding time by 30%." Conclude with a soft call-to-action that feels inviting rather than pushy, such as, "Would you be open to a quick 15-minute call next week?"

Keeping Messages Short and Value-Focused

A compelling subject line gets your message opened, but concise content keeps the recipient engaged. InMails under 300 characters get 19% more responses, so aim for brevity while delivering value. Stick to 2–3 sentences that quickly convey the purpose of your outreach.

Every word should earn its place. Skip unnecessary adjectives, avoid jargon that complicates your message, and leave out lengthy company descriptions - your LinkedIn profile or website can provide that context if needed.

Focus on outcomes, not features. For example, instead of saying, "We help teams streamline project management", you could ask, "Would you like to reduce your project delivery time significantly?" This approach centers the conversation on the recipient’s potential benefits.

Make sure the most important information is front and center. If the recipient only reads the first sentence, they should immediately understand why you’re reaching out and what’s in it for them.

Leveraging AI tools can also make personalization at scale much easier. For example, Enreach’s AI sales agents, combined with expert insights, help create tailored and concise outreach messages that drive 40% higher engagement rates. This blend of technology and thoughtful messaging ensures your InMails stand out in even the busiest inboxes.

Timing, Targeting, and Follow-Up Methods

The success of your InMail campaigns hinges on three key elements: timing, targeting, and follow-up.

When to Send InMail for Best Results

Timing is everything when it comes to InMail. Aim to send your messages during business hours - early morning or midday - when professionals are more likely to check their inboxes. Be mindful of your prospect's time zone to ensure your message lands during their workday.

Steer clear of early Monday mornings or late Friday afternoons, as these times often coincide with the start or end of the workweek when people are less likely to engage. While some industries may operate differently, weekends are generally not ideal unless you're confident your audience works on an unconventional schedule.

Once you've nailed the timing, the next step is identifying the right people to reach out to.

Finding High-Value Prospects

To make your outreach efforts count, use tools like Sales Navigator to filter and identify decision-makers who are both engaged and relevant to your goals. Pay special attention to individuals who have recently changed roles - they may be more open to new opportunities or connections.

Profiles marked as "Open Profile" can also signal a willingness to engage with new contacts. Additionally, mid-market companies often strike a balance between accessibility and decision-making power, making them a great target. If you share mutual connections with a prospect, mention them in your message to establish trust and encourage a response.

Once you've identified your key prospects, it's time to craft a follow-up strategy that keeps the conversation going.

Creating Multi-Channel Follow-Up Workflows

A single InMail is rarely enough to secure a conversion. To build stronger connections, integrate follow-ups across multiple channels like email and Telegram.

After sending your initial InMail, wait 2–3 days before following up with a polite message or a personalized connection request. Reinforce your outreach with additional touchpoints such as an email or a Telegram message to keep your communication consistent and engaging.

Platforms like Enreach can simplify this process. Their AI-driven sales tools coordinate LinkedIn and Telegram outreach while maintaining a personalized approach. This ensures no prospect slips through the cracks while still delivering tailored messages.

Monitor engagement across all channels to determine which methods resonate most with your audience. Each interaction should provide value - whether it’s sharing industry insights, referencing relevant news, or offering helpful resources. By doing so, you'll position yourself as a trusted advisor rather than just another salesperson vying for attention.

Scaling Outreach with Automation and AI

Running manual InMail campaigns can quickly become unmanageable as your list of prospects grows. That’s where automation and AI step in, taking care of repetitive tasks while keeping interactions personal.

How Automation Simplifies InMail Campaigns

The hardest part of InMail outreach isn’t just crafting the perfect message - it’s juggling large prospect lists while ensuring every message feels tailored. Automation tools handle the heavy lifting by scheduling messages, tracking responses, and organizing your outreach pipeline. Platforms like Enreach go a step further with AI Sales Agents that create personalized messages using their database of over 500 million contacts. This means your team spends less time on repetitive tasks and more time on what really matters: closing deals and building meaningful relationships.

Enreach also offers guidance from in-house specialists to ensure your automated campaigns maintain the feel of a personal touch.

But it doesn’t stop at streamlining your messaging. Expanding your outreach to multiple channels can take your engagement efforts to the next level.

Connecting LinkedIn InMail with Other Channels

While automated InMail is a great starting point, integrating additional platforms into your outreach strategy helps create more opportunities to connect with prospects.

Take Telegram, for instance. It’s becoming a popular tool for business communication, and adding it to your strategy can help you reach professionals who prefer this platform. Enreach’s system makes it easy to coordinate messaging across platforms. For example, if someone doesn’t respond to your LinkedIn InMail, the platform can automatically follow up with a message on Telegram or email, ensuring you stay on their radar without being intrusive.

The key to making multi-channel outreach work is effective data management. By analyzing interactions across platforms, you can identify which channels drive the best results and fine-tune your strategy to focus on what works.

With AI-driven tools, you can also ensure your messages are targeted and relevant. Instead of blasting generic content across every platform, these tools help you reach the right people on the right channels, boosting response rates while avoiding audience fatigue.

Measuring and Improving InMail Campaigns

Tracking the performance of your InMail campaigns is crucial for refining your B2B outreach strategy. With the right metrics, you can pinpoint what’s working and make informed adjustments to improve outcomes. Below, we break down the key metrics and strategies that can help you measure and optimize your InMail efforts.

Key Metrics for Tracking Performance

When it comes to measuring the success of your campaigns, certain metrics stand out:

• Response Rate: This is the cornerstone of your campaign performance. It measures how many recipients reply to your messages, whether positively or negatively. For B2B campaigns, a response rate between 10-25% is considered solid, though this varies depending on your industry and audience.

• Open Rate: While LinkedIn doesn’t provide direct open rate data like traditional email platforms, you can infer performance by analyzing response patterns and timing. Quick responses - often within 24-48 hours - indicate that your subject lines are grabbing attention.

• Conversion Rate: This metric tracks how many responses turn into actual business opportunities, such as scheduled demos, sales calls, or pipeline additions. Even a modest 2-3% conversion rate can drive significant revenue when you’re reaching hundreds of prospects each month.

• Cost per Lead: If you’re using LinkedIn Sales Navigator or purchasing InMail credits, understanding your cost per lead is essential. Divide your total investment (including tools, subscriptions, and time) by the number of qualified leads to evaluate the platform’s efficiency compared to other channels.

• Time to Response: Timing matters. Tracking how long it takes for prospects to reply - whether to an initial message or a follow-up - can help you fine-tune your outreach cadence, ensuring you’re neither too aggressive nor too passive.

A/B Testing and Ongoing Improvement

To enhance your campaigns, systematic testing is key. Experimenting with different elements of your messages can yield valuable insights over time:

• Subject Lines: Test direct approaches like “Quick question about [Company Name]’s growth strategy” against benefit-driven lines such as “Helping [Company Name] reduce customer acquisition costs by 30%.” The right subject line can dramatically improve engagement.

• Message Length: While shorter messages often perform better, some audiences may appreciate more detailed outreach that demonstrates a deeper understanding of their needs. Testing different lengths can reveal what resonates most with your prospects.

• Call-to-Action (CTA): Experiment with specific CTAs like “Are you available for a 15-minute call this Thursday at 2:00 PM?” versus open-ended ones like “Would you be interested in learning how we’ve helped similar companies?” Small tweaks can lead to noticeable differences in response rates.

• Personalization Depth: Striking a balance between generic and overly detailed messages is crucial. Compare messages that reference recent company news to those that address specific job postings or industry challenges to find the right level of customization.

When conducting A/B tests, change only one element at a time and ensure your test groups are similar in size - ideally 50-100 messages per variation. Tools like Enreach simplify this process by automating performance tracking and helping you quickly identify the most effective approaches.

Manual vs. Automated Outreach Comparison

Deciding between manual and automated outreach depends on your goals, audience, and available resources.

A hybrid approach often works best. Use automation for broad outreach and initial lead qualification, then transition to manual efforts for high-priority prospects. This allows you to balance efficiency with the personal touch needed to close important deals.

Key Takeaways for LinkedIn InMail Outreach

To make LinkedIn InMail outreach work, you need to strike a balance between making it personal and keeping it scalable. Here's a closer look at the core tactics that can elevate your approach:

Personalization is the cornerstone of success. Tailor your messages by highlighting one or two specific details about the prospect. This could be a recent achievement at their company, a current trend in their industry, or even a challenge they might be navigating. Showing you’ve done your homework builds trust and grabs attention.

Timing and targeting are critical. Aim to send your InMails during mid-week business hours when professionals are most engaged. But timing alone isn’t enough - ensure you’re reaching the right audience. Focus on decision-makers who have the authority and resources to act on your solution. A well-targeted message always outperforms a mass-blasted one.

Automation can expand your reach without sacrificing a personal touch. Use tools like Enreach to handle the initial outreach and follow-ups at scale. For high-priority prospects or warm leads, switch to manual interactions to build stronger connections. This hybrid approach helps you stay efficient while keeping conversations authentic.

Track performance and test consistently. Monitor key metrics like response rates, conversion rates, and cost per lead to gauge success. A/B testing can be a game-changer - experiment with subject lines, message lengths, and calls-to-action to see what resonates best. Let the data guide your adjustments, not assumptions.

Combine InMail with other channels for greater impact. When prospects see your message across multiple platforms, it reinforces your value proposition and increases the chances of engagement. Pair InMail with email, phone outreach, or even social media touchpoints for a seamless strategy.

Ultimately, LinkedIn InMail works best when you treat it as a way to build relationships rather than just pitch your product or service. Focus on offering value and sparking genuine conversations. With the right mix of personalization, thoughtful timing, strategic automation, and consistent measurement, InMail can become a reliable tool for driving leads and closing deals in the B2B space.
