Integrated Outreach: Combining InMail, Email, and Calls
May 23, 2025
You've spent hours perfecting your outreach strategy, crafting messages that should resonate with your ideal prospects. Yet your inbox remains eerily silent, with response rates hovering in the single digits. Despite your IT and engineering prospects being visibly active online, your messages seem to vanish into the digital void.
This frustrating disconnect between prospect visibility and engagement isn't just in your head. In today's saturated communication landscape, where 85% of emails are spam and up to 36% are ads, breaking through the noise requires more than just persistence—it demands an integrated approach.
Why Single-Channel Outreach Falls Short
The days of relying solely on cold emails or LinkedIn InMails are behind us. Many sales professionals report diminishing returns from isolated channels:
"I never had success with Sales Navigator and it doesn't offer me anything a normal LinkedIn search wouldn't," shares one frustrated sales rep on Reddit.
Meanwhile, others question email's effectiveness: "What's the success rate with email? I'm trying to book meetings with mid-sized engineering consulting firms but it feels like a guessing game."
The truth is that neither channel alone consistently delivers optimal results. Each has inherent limitations:
Email: High visibility but increasing deliverability challenges and spam filters
LinkedIn InMail: Direct access but limited daily capacity and varying engagement by industry
Phone calls: Personal touch but low connection rates and potential interruption
The Power of an Integrated Approach
The most successful outreach strategies don't force prospects to conform to a single communication channel. Instead, they create multiple touchpoints across platforms where prospects already spend their time.
As one experienced sales professional put it: "It's not a one or the other sales environment anymore, it's a 'Yes and...' All of the above!"
This integrated approach delivers several key advantages:
Amplified visibility: Each additional channel reinforces your message and increases the chances of breaking through
Preference accommodation: Different prospects prefer different communication methods
Trust building: Consistent messaging across multiple channels establishes credibility
Pattern interruption: Varying your approach prevents your outreach from blending into the background noise
Creating an Effective Multi-Channel Outreach Cadence
A well-orchestrated outreach cadence coordinates touchpoints across channels to create a cohesive buyer journey. Here's a framework that combines InMail, email, and calls effectively:
1. Research and Preparation (Day 0)
Identify target buying personas within IT/Engineering departments
Verify job title/function and contact information
Research prospect's recent activity/posts for personalization opportunities
Prepare personalized talking points for each channel
2. Initial Connection (Day 1)
Send personalized LinkedIn connection request with context (not a sales pitch)
Follow prospect's company page and relevant hashtags
3. Value-First Email (Day 3)
Send initial email with personalized subject line focused on their specific challenges
Include valuable content relevant to their role/industry
Keep it concise with a clear but soft call to action
4. LinkedIn Engagement (Day 5)
Like or thoughtfully comment on prospect's recent content
Share relevant article/insight on your feed that addresses their challenges
5. InMail Follow-Up (Day 7)
Send InMail using AIDA structure (Attention, Interest, Desire, Action)
Reference previous touchpoints naturally
Focus message on specific value for their role
6. Phone Outreach (Day 9)
Make call with prepared talking points
Leave voicemail if no answer, mentioning previous touchpoints
Follow up with brief email noting your call
7. Final Value-Add (Day 12)
Share personalized, high-value content via most responsive channel
Include soft call to action with clear next steps
This structure prevents overwhelming prospects while maintaining consistent presence. The key is personalization at each touchpoint while tracking which channels yield the best engagement for each prospect.
Tracking and Measuring Multi-Channel Success
The old sales adage is true: "You can't manage what you can't measure." But tracking engagement across multiple channels presents unique challenges, especially when tools don't seamlessly integrate.
As one sales operations leader noted, "We basically had no solid activity reporting in Salesforce prior to this, and reps are always complaining about Outreach data."
Here's how to establish effective cross-channel measurement:
Key Metrics to Track by Channel
LinkedIn/InMail Metrics:
Connection acceptance rate
InMail open and response rates (aim for 50%+ open rate)
Content engagement (likes, comments, shares)
Profile view reciprocation
Email Metrics:
Deliverability rate (watch for bounce backs)
Open rates (benchmark by industry)
Reply rates and sentiment
Click-through rates on content
Call Metrics:
Connection rate
Call duration
Next steps secured
Voicemail response rate
Holistic Performance Indicators
Beyond channel-specific metrics, track these cross-channel KPIs:
Total touches before response
Most effective first-touch channel
Most effective response-generating channel
Average days to meaningful engagement
Channel preference by buyer persona
Integration and Attribution
The technical challenge of connecting these dots can be significant. Many teams struggle with "the hardest part will be ensuring Outreach is setup to produce good structured data to be passed into Salesforce."
Solutions to consider:
Ensure proper CRM integration: Configure your outreach tools to sync activity data with your CRM. For Salesforce users, enable Advanced Task Mapping in tools like Outreach to maintain data integrity.
Implement a tracking system: Use unique tracking parameters for links in different channels to attribute engagement correctly.
Adopt a unified inbox solution: Tools like Kondo can transform your LinkedIn messaging experience by organizing conversations with labels and split inboxes—particularly valuable for separating hot leads from general networking.
Kondo's keyboard shortcuts and reminders feature can dramatically speed up your LinkedIn workflow. As one user noted, "Kondo has transformed my previously chaotic LinkedIn inbox into an organized system where no important lead gets lost."

Channel-Specific Best Practices
Each outreach channel requires specific optimization to maximize effectiveness:
LinkedIn InMail
Keep it concise: Aim for 100 words or less—busy professionals skim longer messages
Personalize authentically: Reference specific content they've engaged with
Avoid built-in AI templates: As one recruiter warned, "Never use the in-built AI, it's shit."
Target strategically: "Executives respond in high percentages because their available opportunities are very small at any given time, so it's in their best interest to network and respond."
Time it right: Avoid sending InMails on Fridays and weekends when engagement drops
For IT/Engineering prospects specifically, make technical relevance clear immediately. These personas are often bombarded with irrelevant outreach, so demonstrating you understand their technical world is crucial.
Email Outreach
Subject line optimization: A/B test different approaches (question-based, personalized, value-proposition)
Mobile optimization: Ensure readability on mobile devices where 60%+ of emails are opened
Clear CTA: Include one obvious next step—multiple CTAs reduce response rates
Follow-up sequence: Plan 3-5 follow-ups with different angles while avoiding "just checking in"
Technical validation: For IT/Engineering prospects, demonstrate technical credibility early
Call Strategy
Pre-call research: Review all previous touchpoints before calling
Value in voicemail: Leave concise voicemails (30 seconds max) with clear value proposition
Pattern interruption: Ask unexpected questions to break through the standard call screening
Technical specificity: For IT/Engineering prospects, be precise about technical use cases
Follow-up documentation: Send recap email/message after meaningful conversations
Team Approach to Multi-Channel Outreach
For organizations with specialized roles, consider a team mixed methods approach:
SDR: Manages initial LinkedIn engagement and email outreach
AE: Makes phone calls and joins high-value meetings
Marketing: Provides targeted content for specific personas and pain points
RevOps: Ensures proper tracking and tool integration
Adding Kondo to Your Integrated Strategy
When implementing this multi-channel approach, the LinkedIn component often becomes chaotic. Kondo can significantly enhance your LinkedIn messaging workflow by:
Organizing conversations with labels: Categorize prospects by stage, interest level, or campaign
Setting follow-up reminders: Never forget to follow up on a hot lead with the snooze feature
Saving time with snippets: Create templates for common responses that still feel personalized
Syncing activity with your CRM: Push important LinkedIn conversations to your core systems

Conclusion: The End of the Single-Channel Era
The most successful sales professionals recognize that the debate between LinkedIn, email, or calls is outdated. As one veteran sales rep put it: "It's all about incremental improvements. I've worked out what does/doesn't work for me over the past 12 years."
The future belongs to those who can orchestrate meaningful, personalized touchpoints across multiple channels while maintaining meticulous tracking of what works for each prospect and persona.
By implementing an integrated outreach strategy with proper measurement systems, you'll not only improve response rates but also gain invaluable insights into your market's communication preferences—ending the guessing game once and for all.
