When to Use Email vs. LinkedIn in Outbound

In the modern outbound playbook, the debate is no longer about *whether* to use multiple channels, but *how*. The two most powerful channels for B2B prospecting, email and LinkedIn, are often treated as interchangeable. This is a strategic error. Each platform has a unique culture, etiquette, and set of strengths. A successful multi-channel strategy does not just use both; it uses each for what it does best.

Two distinct but interconnected pathways, one a straight line (email), the other a social network graph (LinkedIn), leading to the same target.

Email: The Channel for Scale and Formal Communication

Email remains the backbone of most outbound campaigns for a reason. It is universal, professional, and built for asynchronous, detailed communication.

Strengths of Email:

• Scale: With proper deliverability management, email allows you to reach a large, targeted audience efficiently.
• Rich Content: Email is ideal for sharing detailed information, attaching case studies, or embedding links to landing pages and videos.
• Automation: Email is perfectly suited for building complex, automated follow-up sequences that can run for weeks or months.
• Professional Context: It is the accepted channel for formal business communication, making it appropriate for initiating contact with senior decision-makers.

When to Use Email:

• For your primary, scaled outreach campaigns.
• When you need to send detailed information or proposals.
• For automated nurturing and follow-up sequences.
• When contacting senior executives who may not be active on social media.

LinkedIn: The Channel for Precision, Research, and Social Proof

LinkedIn is not just another inbox. It is a social platform built on professional identity and relationships. Using it like email is a recipe for being ignored. This is a key part of why we advise that your GTM strategy should have fewer channels, used more effectively.

Think of email as your broadcast tower and LinkedIn as your sniper rifle.

Strengths of LinkedIn:

• Research Goldmine: A prospect's LinkedIn profile tells you their career history, skills, connections, and recent activity—a treasure trove for crafting hyper-relevant messages.
• Social Proof and Credibility: A connection request or message on LinkedIn is backed by your professional profile, creating instant credibility that a cold email lacks. Mutual connections add another powerful layer of trust.
• Informal and Conversational: LinkedIn messages (InMail or DMs) allow for a more casual, conversational tone that can be more effective for relationship-building.
• Multiple Touchpoints: You can engage with a prospect by liking their posts, commenting on their content, or sending a connection request—all before you ever send a direct message.

When to Use LinkedIn:

• To warm up a prospect before you send an email. (e.g., Send a connection request, then an email a day later).
• As a secondary channel in your follow-up sequence if your emails are getting no response.
• For highly targeted, "spear-fishing" campaigns aimed at a small number of high-value prospects.
• To engage with prospects who are active on the platform by commenting on their posts.

The Winning Strategy: Orchestration

The best strategies do not choose one channel over the other; they orchestrate them. A typical sequence might look like this:

Day 1: View prospect's LinkedIn profile. Send email #1.
Day 3: Send LinkedIn connection request with a short, non-salesy note.
Day 5: Send email #2 (if no reply).
Day 7: Like or comment on the prospect's recent LinkedIn activity.
Day 10: Send LinkedIn message (if they accepted your request).
Day 14: Send email #3.

By using each channel for its unique strengths, you create a "surround sound" effect. You are no longer just a cold email in their inbox; you are a persistent, professional, and familiar presence. That is how you turn a multi-channel strategy into a revenue-generating machine.
