In a world where digital distractions are the norm, getting your customer’s attention—let alone holding it—has never been more challenging. Engagement isn’t just a buzzword anymore. It’s the make-or-break of your marketing efforts.
That’s where multi-channel marketing steps in. It’s not about doing everything. It’s about showing up where your audience already is—whether that’s in their inbox, on their phone, or nudging them gently through an app.
Two platforms—Customer.io and HubSpot—make that a whole lot easier. Separately, they’re powerful. Together? They give you a way to build smarter, more human customer journeys. And when integrated right, they can turn your engagement strategies from reactive to real-time.
Let’s break it down.

What Multi-Channel Marketing Really Means
Think email, SMS, push notifications, in-app messages. Now imagine all of those communicating with a customer—not in chaos, but in rhythm.
That’s multi-channel marketing. And no, it’s not the same as just “being on more platforms.” It’s about coordination. Context. Relevance.
Customer.io gives you the tools to orchestrate these channels. HubSpot brings the visibility and customer lifecycle insights to back it all up. If you’re only relying on email right now, you’re probably missing touchpoints where your customers actually hang out.
It’s not about doing more. It’s about doing what matters.
Why It Works Better Than You Think
Here’s what changes when you stop shouting into one channel and start listening across many:
- Your brand gets seen more—without being annoying.
- Messages land where they make sense. A promo in email, a reminder in SMS, a “we miss you” push that actually feels timely.
- You start responding to behavior, not just guessing.
The result? Customers feel understood. Not stalked.
Because now, instead of throwing messages into the void, you're responding to a cart that was just abandoned, a birthday coming up, or a product they’ve browsed three times but never bought. That’s behavioral targeting in action. And it’s where the engagement metrics start looking real.
And those metrics—click-throughs, conversions, lifetime value—they're not just numbers. They're signals that your customers are paying attention.
Building Behavior-Based Journeys with Customer.io
Customer.io is built for this kind of marketing. You get advanced segmentation that doesn’t just pull from static fields—it evolves as your customers do.
Say someone browses your product page but doesn’t convert. A follow-up email is great. But what if they ignore it? You could follow with an SMS two days later. Or a push notification the next time they open your app.
Birthday discounts. First purchase thank-yous. VIP-only sneak peeks. All automated, all behavior-triggered.
One example we’ve seen work? A travel brand set up a journey triggered by abandoned searches. If a user looked at Paris trips twice in one week but didn’t book, they got a mobile notification offering 10% off flights. Clicks and conversions doubled.
You’re not creating a email marketing campaign. You’re building conversations that feel alive.
Where HubSpot Comes In
HubSpot might not be your first thought for multi-channel engagement, but it should be. Think of it as your command center.
It’s where you track lifecycle stages, see where someone is in the funnel, and understand their past behavior—all before sending that next message.
Its strength lies in visibility. You’re not just sending messages—you’re reading the full story before hitting “go.”
Better still, syncing HubSpot data with Customer.io means you’re not working from two separate realities. It’s one clear picture of who your customer is, where they’ve been, and what might matter next.
And because HubSpot handles forms, landing pages, and lead scoring, you’ve already got context at your fingertips.
Integrating the Two: The Sweet Spot
Here’s where it gets interesting.
Connect HubSpot and Customer.io, and suddenly your CRM data isn’t just for sales—it powers your marketing automations too.
You can trigger a Customer.io journey when a deal stage changes in HubSpot. Or customize a message flow based on a HubSpot score or tag. All without losing that personal touch.
That means fewer dropped leads. Fewer messages that feel “off.” More timely nudges that actually work.
This isn’t about overwhelming your audience. It’s about building trust in tiny, consistent moments.

Getting It All Working Together
To make it work, you’ll need a few basics:
- Active accounts on both Customer.io and HubSpot.
- A connector tool—Zapier is common, but direct API setups work too if you’ve got dev resources.
- Time to define your triggers, map your fields, and actually test your flows.
And here’s the part most teams skip: mapping out real customer journeys. Not generic “email -> SMS -> email” flows, but ones tied to your actual funnel. Think: “First demo booked” → “Onboarding checklist sent” → “Weekly usage report triggered.”
It’s this intentionality that separates noise from strategy.
Testing is non-negotiable. It’s where you catch an SMS that hits too early or an email that doesn’t feel personalized enough. Start small. One journey. One channel. Then layer on.
