Are your onboarding emails actually helping new customers, or just filling their inbox with noise? If you’re wrestling with Mailchimp, HubSpot, ActiveCampaign, or any of the big B2B marketing automation names, you’ve probably wondered if there’s a better way to guide users from “just signed up” to “actually getting value.” This guide is for SaaS founders, marketers, and anyone tired of sifting through sales pitches and feature lists. We’ll cut through the fluff and get honest about what these tools actually do, where they let you down, and how to set up onboarding that actually works.
What Does “Customer Onboarding” Mean, Really?
Let’s get clear: onboarding isn’t just a welcome email. It’s the first real experience customers have with your product, and it’s where most B2B companies lose people. Good onboarding nudges users to take important actions (think: “connect your CRM,” not “read our blog”). It should feel personal, timely, and—above all—useful. Automation tools promise to make this easier, but the devil’s in the details.
Quick Snapshot: The Main Players
Before we get into the nitty-gritty, here’s who we’re looking at:
- Mailchimp Journeys: Entry-level, straightforward, but a bit rigid.
- HubSpot Workflows: Tons of features, can get expensive fast.
- ActiveCampaign Automations: Good balance of power and usability.
- Marketo Engage: Enterprise-grade, but often overkill for smaller teams.
If you’re considering something outside these, don’t worry—the same principles mostly apply.
1. Building Onboarding Flows: How Flexible Is Each Tool?
Mailchimp Journeys:
Mailchimp’s “Customer Journeys” builder is drag-and-drop simple. You set triggers (like someone signing up), add steps (emails, delays, tags), and that’s about it. If your onboarding is a straight line—welcome email, tip #1, tip #2—it works. But if you need logic like “If user did X, send Y,” or want to grab data from your app, you’ll hit limits fast.
- What works: Easy to set up. Good for linear, basic sequences.
- What doesn’t: Conditional logic is limited. No built-in way to trigger actions based on in-app behavior unless you pipe in custom events via API or integrations (which can get fiddly).
HubSpot Workflows:
HubSpot lets you build complex branches, use almost any data point as a trigger, and even automate CRM updates along the way. You can pause flows, score leads, or send Slack messages—all in one place.
- What works: Fine-grained control. Can personalize for just about any scenario.
- What doesn’t: Can feel overwhelming if you just want to send a few emails. Price ramps up quickly as you unlock “pro” features.
ActiveCampaign Automations:
Falls somewhere between Mailchimp and HubSpot. The visual builder supports branching, and you can use tags, custom fields, and site tracking to personalize flows.
- What works: More flexibility than Mailchimp, but less overwhelming than HubSpot.
- What doesn’t: Advanced features (like site tracking or deep CRM integration) can be finicky to set up.
Marketo Engage:
Marketo is powerful but not friendly. It’s built for teams with an admin who eats marketing automation for breakfast. You can create any workflow you can imagine—if you have the time and patience.
- What works: No real limits on complexity.
- What doesn’t: The learning curve is steep. Not worth it unless you have a big team and budget.
Pro tip:
If you’re new to automation, start simple. Most onboarding improvements come from basic flows you actually maintain, not from building a Rube Goldberg machine of triggers and tags.
2. Data & Triggers: How Well Do They React to Real User Behavior?
Mailchimp Journeys:
You get basic triggers—sign up, joins a list, opens an email. If you want to trigger based on in-app activity (like “user invited a team”), you’ll need to push those events to Mailchimp using integrations or the API. This works, but it’s not out-of-the-box, and there are limits on how many times someone can flow through a journey.
HubSpot:
Just about any data you can get into HubSpot—form fills, deal stage changes, custom properties—can trigger a workflow. If your product data lives elsewhere, you’ll need to sync it, but there are tons of prebuilt integrations and a solid API.
ActiveCampaign:
Supports tags, custom fields, and site tracking. You can trigger automations when someone visits a certain page or clicks a link. It’s not as deep as HubSpot out of the box, but good enough for most SaaS onboarding.
Marketo:
If you can get the data in, you can trigger on it. But “getting the data in” is the catch. Marketo assumes you have a technical team to wire up all the integrations.
Honest take:
If your onboarding depends on granular in-app events (like “user finished setup”), Mailchimp’s going to feel limiting unless you’re ready to build custom integrations. HubSpot and Marketo are better for this, but make sure you’re actually using that complexity—otherwise, it’s just extra maintenance.
3. Personalization: Can You Make Messages Actually Feel Personal?
Mailchimp Journeys:
You can personalize emails with merge tags (like {first_name}), but that’s about it. Dynamic content or branching based on user attributes is limited.
HubSpot:
Supports dynamic content, smart send times, and branching based on just about any property. You can create different onboarding paths for different user segments without much pain.
ActiveCampaign:
Good personalization with tags and custom fields, plus decent conditional content in emails. Not as deep as HubSpot, but it covers most needs.
Marketo:
As flexible as you want, but again, setup is complex.
What to ignore:
Don’t get lost chasing “hyper-personalized” onboarding unless you have the data and resources to keep it accurate. Most users just want timely, relevant help—not creepy levels of detail.
4. Reporting: Can You Tell What’s Actually Working?
Mailchimp Journeys:
Basic reporting—opens, clicks, unsubscribes. You’ll see how many people finished the journey, but tying email performance to product usage takes extra work.
HubSpot:
Much deeper analytics. You can track which steps in a workflow convert, see attribution across channels, and (if you set it up) tie onboarding emails to product milestones.
ActiveCampaign:
Solid reporting on email engagement and automation paths. Product usage correlation is possible, but often requires extra integration work.
Marketo:
Enterprise-level reporting, but it’s only as good as the data you feed it. Setup is not for the faint of heart.
Real talk:
Most teams don’t look at onboarding metrics after setup. Pick one or two numbers that matter (like “users who complete onboarding send 5x more messages”) and focus on those. Fancy dashboards won’t fix a broken onboarding flow.
5. Integrations & Ecosystem: Can You Connect the Dots?
Mailchimp Journeys:
Decent integration library, but mostly focused on ecommerce and basic SaaS tools. If you need to sync with a custom app, expect to spend time with Zapier or the API.
HubSpot:
Huge integration marketplace, including deep connections with CRMs, help desks, and just about everything else. If you’re all-in on HubSpot, life is easier.
ActiveCampaign:
Good selection of integrations, especially for CRMs and e-commerce. Custom integrations are possible, but you might need technical help.
Marketo:
Connects to just about anything—if you have the technical chops.
Bottom line:
Don’t buy a tool for its integration list. Check if it actually syncs what you need, in real time. Test it with real data before you commit.
6. Pricing: What Are You Really Paying For?
Mailchimp Journeys:
Included in most paid tiers. Pricing is mostly based on list size. Good value for simple needs, but costs can creep up if your list grows fast.
HubSpot:
Expensive, especially as you add features. The “free” tier is very limited for automation. Be prepared for add-on costs.
ActiveCampaign:
Middle of the road. More affordable than HubSpot, with most automation features included in standard plans.
Marketo:
Enterprise pricing. If you’re asking “how much does it cost?” it’s probably not for you.
No-BS tip:
Don’t pay for features you won’t use. It’s easy to get sold on “future needs,” but most onboarding flows only use 10% of what these tools can do.
So, Which Tool Should You Use for B2B Customer Onboarding?
- Mailchimp Journeys is great if you want to get started quickly, need basic automation, and don’t have edge-case needs. If your onboarding is mostly “send 3 emails over a week,” it’s fine.
- HubSpot is for teams that need deep personalization, lots of data triggers, and don’t mind paying for it.
- ActiveCampaign hits the sweet spot for many B2B SaaS companies who want more flexibility than Mailchimp but don’t want to learn another CRM.
- Marketo is overkill for most, unless you’re running onboarding for a massive product with a big ops team.
Keep it simple:
Most onboarding problems aren’t solved with fancier tools—they’re fixed by better copy, clearer calls to action, and actually watching what new users do. Start with a basic flow, see where people drop off, and tweak from there. Don’t let “automation” become an excuse to ignore your customer experience.
If you actually want onboarding that works, focus less on features and more on what your users need to succeed. The right tool is the one you’ll actually use—and update.
