Clear internal communication can make or break your company culture. When employees understand what's happening and why, they're more engaged, productive, and likely to stick around.

An effective internal communications strategy transforms scattered messages into purposeful conversations that align your entire organization. I'll explore how you can upgrade yours using AI video technology that makes communication both simpler and more impactful.

Here's a quick example from our CEO, Victor (hint: it's actually a Synthesia video made with Victor's personal avatar).

What Is an Internal Communications Strategy?

An internal communication strategy is a structured plan that determines how information flows within your organization. It outlines which messages are shared, when they're delivered, who receives them, and which channels are used.

Poor internal communication costs U.S. businesses up to $2 trillion annually in lost productivity. Only 13% of employees strongly agree that their leadership communicates effectively.

Unlike ad-hoc messaging, a strategic approach creates consistency, builds trust, and supports broader organizational objectives through planned communication tactics.

Step 1: Audit Your Current Communication Challenges

Start by identifying where your current internal communications fall short:

  • Document engagement metrics for existing channels (email open rates, intranet visits)
  • Map communication pain points across departments and regions
  • Calculate time spent on repetitive communication tasks by leadership and HR teams

Warning signs to look for:

  • Email open rates below 30% indicate message fatigue
  • Questions about the same topics repeatedly asked show information isn't sticking
  • Only 43% of employees report having clear feedback channels

Step 2: Start With High-Impact, Low-Risk Content

Transform these common internal communication types first:

Routine updates: Replace text-heavy emails with brief, engaging video announcements.

Policy communications: Convert complex policies into visual explanations—I've seen companies achieve up to 600% higher engagement with video formats.

Welcome messages: Create consistent executive greetings for new hires that establish connection from day one.

Year-end reviews: Switch from dense newsletters to concise video summaries with key highlights.

Step 3: Implement Video-Based Internal Communication Strategies

Use AI avatars for consistency: Create branded video presenters that maintain visual identity across all communications.

Implement easy translations: Ensure consistent messaging across global teams with automatic video translation in 140+ languages.

Add accessibility features: Include subtitles and transcripts to make communications available to all employees.

Enable quick updates: Make content adjustments in minutes when information changes without recreating entire videos.

Step 4: Scale Across Different Communication Types

Apply these best practices across various message types:

Leadership updates: Replace long executive emails with personalized video messages that convey tone and build connection.

Change management: Use video to communicate organizational changes with clarity and empathy.

IT communications: Transform technical updates into digestible visual content that non-technical employees can understand.

HR announcements: Make benefits, policy updates, and compliance information more engaging through conversational video presentations.

Step 5: Optimize Your Content Strategy

Keep videos concise: I recommend aiming for 2-3 minutes maximum to maintain attention and improve retention.

Use consistent presenters: Build familiarity by using the same AI avatars for specific communication types.

Create templates: Develop standard formats for recurring communications to maintain visual consistency.

Batch similar content: Produce multiple related videos in one session to maximize efficiency.

Step 6: Measure and Improve Results

Track these key metrics to evaluate effectiveness:

View rates: Percentage of employees who watched each video (aim for 70%+)

Completion rates: Percentage who watched videos entirely (target 80%+)

Engagement actions: Clicks, comments, or responses (good = 15%+ interaction)

Time savings: Hours saved compared to traditional methods

In my experience, companies implementing these strategies report employees are 6-7x more likely to engage with short videos than text emails.

Advanced Internal Communication Tactics

Executive presence: Create custom avatars for senior leaders to scale their visibility without requiring their time for filming.

Department-specific applications:

  • IT teams: Visual demonstrations of system changes
  • HR departments: Engaging policy and benefits explanations
  • Operations: Visual guides for complex procedures

Engagement boosters:

  • Visual elements: Use backgrounds and graphics that align with your brand
  • Interactive components: Add clickable links or embedded polls
  • Series-based approach: Create episodic content for regular updates
