Introduction
Omnichannel marketing has become the standard for how modern brands reach and retain their customers. In today’s market, shoppers don’t engage with a brand in one place—they move fluidly between Instagram, TikTok, email, Amazon, retail shelves, YouTube, and even in-store events. To succeed, a brand must show up consistently, with a unified voice, across every channel. That is exactly where omnichannel marketing comes in.
But what is omnichannel marketing, and why is it essential for businesses in 2025? More importantly, which agencies have the expertise, tools, and creative firepower to deliver it effectively? In this guide, we’ll explore:
- What is omnichannel marketing?
- Why brands need an omnichannel marketing strategy in 2025.
- The role of omnichannel marketing platforms.
- A curated list of the 10 best omnichannel marketing agencies in 2025, including who they serve and why they stand out.
What Is Omnichannel Marketing?
At its simplest, omnichannel marketing is a strategy that connects all of a brand’s customer touchpoints—digital and physical—into a seamless experience. Unlike multichannel marketing, where each channel (like email, social, or retail) may operate independently, omnichannel marketing ensures every interaction feels connected.
Example of an omnichannel journey in action:
- A customer sees a TikTok ad for a new sparkling beverage.
- They click through to Instagram, where the brand’s story highlights show influencer reviews.
- Later, they receive a personalized email with a discount code.
- The same code works on the brand’s Shopify store and at Target.
- After purchase, they’re retargeted with loyalty program ads on Facebook.
Every step is part of one connected ecosystem—no friction, no siloed data, just one consistent brand story.
Why Brands Need an Omnichannel Marketing Strategy in 2025
A strong omnichannel marketing strategy isn’t optional anymore. Customers demand convenience and personalization:
- 73% of consumers expect brands to know their preferences across channels (Salesforce, 2024).
- 82% of smartphone users consult their phones while shopping in-store (Google).
- Brands with solid omnichannel strategies retain 89% of their customers, compared to 33% for those with weak ones (Aberdeen Group).
In 2025, the winners will be the brands that create personalized, real-time connections across every touchpoint. That’s why partnering with the right agency is critical.
The Role of Omnichannel Marketing Platforms
Executing an omnichannel strategy requires technology. Omnichannel marketing platforms—like Salesforce Marketing Cloud, HubSpot, Klaviyo, and Adobe Experience Cloud—help brands unify customer data, automate campaigns, and personalize at scale.
However, platforms are only as powerful as the strategy behind them. That’s where agencies come in: combining creative storytelling with platform expertise to drive growth.
