We've migrated clients between all three of these platforms. More than once, we've watched a business spend six months on a platform that was wrong for them from day one, then spend another six months migrating off it. The cost isn't just the subscription fee. It's the lost campaigns, the broken automations, the re-trained staff, and the leads that fell through the cracks during the transition.
So this isn't a feature checklist. We're going to tell you which platform belongs in which situation and why, based on what we've seen actually work across dozens of implementations.
The Real Pricing Picture
Platform pricing pages are designed to get you in the door. The number you see on the marketing site is almost never the number on your invoice six months later. Here's what these platforms actually cost once you factor in contacts, users, features, and the inevitable add-ons.
Salesforce Marketing Cloud Account Engagement (Pardot) starts at $1,250/month for the Growth edition. That jumps to $2,500/month for Plus, $4,000/month for Advanced, and $15,000/month for Premium. Those are flat rates per org, not per user. Every person on your team can access it under a single licence. For a 15-person marketing and sales team, that per-user math looks very different from HubSpot's seat-based model. The catch: you need Salesforce CRM. Pardot without Salesforce is like buying a turbocharger for a car you don't own.
Mailchimp looks cheap at first. The Standard plan starts at $20/month for 500 contacts. But Mailchimp's pricing scales with your list size, and it counts unsubscribed contacts and unconfirmed opt-ins against your total. A business with 10,000 contacts on the Standard plan is paying roughly $135/month. At 50,000 contacts, you're over $350/month. The Premium plan starts at $350/month for 10,000 contacts. Intuit's acquisition of Mailchimp in 2021 brought steady price increases, and in early 2026 they halved the free plan to just 250 contacts and 500 emails per month. The free tier is no longer a serious starting point for any real business.
HubSpot Marketing Hub starts at $15/month per seat for Starter, which includes 1,000 marketing contacts. That sounds affordable until you need the Professional tier at $890/month (with 2,000 contacts and three seats included), plus a mandatory $3,000 onboarding fee. Enterprise runs $3,600/month with 10,000 contacts and five seats, plus a $7,000 onboarding fee. Additional marketing contacts cost $50/month per 1,000 on Professional, and extra seats are $45/month each. A mid-size team of eight people with 25,000 contacts on HubSpot Professional can easily spend $2,000/month when you add up seats and contact tiers.
None of these are cheap once you're past the entry level. But comparing them on sticker price alone misses the point. The question is what you get for the money, and whether the platform fits the way your team actually works.
Where Each Platform Wins
We have strong opinions here because we've worked inside all three of these platforms extensively. We've built automation workflows, debugged deliverability issues, migrated contact databases, and trained teams. The differences show up fast once you're past the demo.
Pardot: The B2B Sales Machine
Pardot's strength is the depth of its Salesforce integration. This isn't a marketing tool that also connects to your CRM. It's a marketing layer that lives inside your CRM. Lead scoring in Pardot pushes directly to Salesforce opportunity records. A prospect hits a scoring threshold and the assigned sales rep gets a notification in Salesforce with the full engagement history attached. No export, no sync delay, no middleware.
Einstein Behaviour Score takes this further by using machine learning to identify which prospect actions actually correlate with closed deals in your specific pipeline. It learns from your data, not industry benchmarks. For B2B companies with sales cycles longer than 30 days, this kind of scoring is where real pipeline acceleration happens.
Pardot's Engagement Studio is the most capable B2B automation builder we've worked with. Branching logic based on CRM field values, wait steps tied to sales activity, auto-updating list membership based on live CRM data. We've built nurture sequences for clients that run six months with dozens of decision branches, all pulling live data from Salesforce objects. You can't do that in Mailchimp. You can approximate it in HubSpot, but not with the same CRM depth.
The downsides are real, though. The learning curve is steep. The interface has improved since the rebrand to Marketing Cloud Account Engagement, but it still feels like enterprise software. Non-technical marketers struggle with it. And the entry price of $1,250/month assumes you're already paying for Salesforce CRM, which adds another $25-$300/user/month depending on your edition.
Mailchimp: The Quick-Start Sender
Mailchimp does one thing extremely well: it lets you build and send email campaigns fast. The drag-and-drop email builder is genuinely good. Template selection is broad. The audience segmentation tools, while not as deep as Pardot's or HubSpot's, handle the basics that most small businesses need. If your primary use case is "send a monthly newsletter to our customer list," Mailchimp gets you there with the least friction.
Mailchimp's reporting is clear and immediate. Open rates, click maps, revenue attribution for e-commerce integrations. For a small retail business or local service company sending a few campaigns per month, the Standard plan at $20-$135/month (depending on list size) is reasonable value.
Where Mailchimp falls apart is automation. The "Customer Journey" builder introduced in recent years is limited compared to HubSpot or Pardot. Branching logic exists but feels constrained. Multi-step workflows with conditional waits, CRM-triggered actions, or lead scoring are either missing or require workarounds. Mailchimp wants to be a marketing automation platform, but it's fundamentally an email sending tool with some automation features bolted on.
The other problem is deliverability at scale. Mailchimp operates on shared sending infrastructure for most plans. Your sender reputation is partially tied to other Mailchimp users on the same IP pool. We've seen clients with clean lists and good content still hit deliverability walls because their shared IP neighbourhood was rough. Dedicated IPs are only available on the Premium plan. If email deliverability matters to your business (and if you're reading this, it should), make sure your SPF, DKIM, and DMARC records are set up correctly regardless of which platform you choose.
HubSpot: The All-In-One Bet
HubSpot's value proposition is that everything lives in one place. CRM, marketing, sales, service, content management. If your company is going all-in on HubSpot across departments, the Marketing Hub benefits from deep connections to every other Hub. A contact's lifecycle stage updates automatically as they interact with your marketing emails, fill out forms, visit specific pages, and get handed to sales.
The workflow builder on Professional and Enterprise is strong. Not quite Pardot's depth on the B2B side, but more flexible in terms of the objects and triggers you can work with across the full HubSpot suite. Smart content (showing different email content based on contact properties) is well implemented. A/B testing is built in at the Professional tier.
HubSpot's real advantage is usability. The interface is clean. The onboarding documentation is extensive. A marketing coordinator with no technical background can build a workflow, create a landing page, and set up a nurture sequence within their first week. Pardot can't claim that. Mailchimp can for basic campaigns, but not for anything involving automation logic.
The trap with HubSpot is cost escalation. You start on Starter, realise you need automation, move to Professional ($890/month plus onboarding), then discover that the features you actually want (custom reporting, calculated properties, adaptive testing) are Enterprise-only at $3,600/month. The seat-based model means adding two more marketing team members costs $90/month in additional seats on Professional. For growing teams, HubSpot's pricing penalises headcount growth in a way that Pardot's org-level licencing does not.
The platform you can afford but can't use properly costs more than the platform that's expensive but fits your workflow. We've seen this play out repeatedly: a team picks the cheapest option, under-uses it for a year, then migrates to the platform they should have started with.
The Decision That Actually Matters
Forget features for a moment. The choice between these three platforms comes down to three questions.
Are you a Salesforce shop? If your sales team lives in Salesforce, Pardot is the answer. Full stop. The CRM integration depth is unmatched. Your sales and marketing data lives in one system with no sync lag, no duplicate records, and no middleware to maintain. We've built and managed Pardot implementations for B2B companies in Calgary and across Western Canada, and the ROI shows up fastest when the sales team is already fluent in Salesforce.
Are you a small team sending campaigns? If you have fewer than 5,000 contacts, no dedicated marketing operations person, and your primary need is sending newsletters and basic automated welcome sequences, Mailchimp's Standard plan is the pragmatic choice. Don't overbuy. But plan your exit strategy, because you will outgrow it.
Are you building a marketing operation from scratch? If you don't have a CRM yet, you want marketing and sales on one platform, and you have the budget for Professional tier or higher, HubSpot is the safest bet. The all-in-one approach avoids integration headaches, and the learning curve is the gentlest of the three.
Which Platform Fits Your Business
- Pardot is for B2B companies already using Salesforce who need lead scoring, long-cycle nurture automation, and sales-marketing alignment at the CRM level. Budget: $1,250+/month plus Salesforce licences.
- Mailchimp is for small businesses and e-commerce companies that need to send campaigns reliably without a steep learning curve. Budget: $20-$350/month depending on list size.
- HubSpot is for growing companies that want marketing, sales, and CRM in a single system with room to scale across departments. Budget: $890+/month for meaningful automation (Professional tier).
- If deliverability problems are tanking your campaigns before platform features even matter, start with your email authentication setup first.
- Don't choose based on current list size. Choose based on what your marketing operation will look like in 18 months.
What We See Go Wrong
The most expensive mistake isn't picking the wrong platform. It's picking the right platform and implementing it poorly.
We've inherited Pardot accounts where the client was paying $2,500/month for Plus but using it as a glorified email sender. No lead scoring configured. No Engagement Studio programs running. No completion actions on forms. They were paying for a race car and driving it to the grocery store.
We've seen HubSpot Professional accounts where every contact was a "marketing contact" (the billable kind) because nobody understood the distinction between marketing and non-marketing contacts. Their monthly bill was double what it should have been. HubSpot's pricing model counts only marketing contacts toward your limit, but if you're not actively managing that classification, every imported contact defaults to billable.
We've seen Mailchimp accounts with 40,000 contacts where 15,000 were unsubscribed or bounced but still counted toward the billing tier. Mailchimp counts those contacts unless you explicitly archive them. That's not a bug in Mailchimp. It's a business model choice.
Platform choice matters. But implementation, ongoing maintenance, and honest assessment of your team's capacity to use the tools matter more. If your email campaigns aren't converting, the answer might not be a better platform. It might be better use of the platform you already have.
Migration Realities
Switching platforms is never as clean as the new vendor's sales team promises. Contact records transfer, but engagement history doesn't migrate cleanly between any of these three. Automation workflows need to be rebuilt from scratch. Custom integrations break. Your team needs retraining.
Pardot to HubSpot migrations are common when companies leave Salesforce. The data mapping takes weeks, not days. HubSpot to Pardot migrations happen when companies adopt Salesforce and realise they need the CRM integration depth. Mailchimp to either Pardot or HubSpot is the most common upgrade path we see, and it's usually the smoothest because Mailchimp's simpler data model means less to untangle.
Budget four to eight weeks for a proper migration with parallel running. Don't cut over in a single weekend. Run both platforms simultaneously for at least two to three weeks to verify deliverability, automation triggers, and data sync before decommissioning the old one.
If you're at the point of evaluating these platforms seriously, the upfront investment in getting the choice right saves multiples of its cost in avoided migration pain. We help companies make this decision and handle the implementation as part of our email marketing and automation work. Getting it right the first time is the whole point.
