Quick answer: Mailchimp is strongest as an approachable email marketing platform that has grown automation and light CRM features. HubSpot is a CRM-centred platform with free CRM entry and paid Marketing, Sales and Service hubs where email is part of a wider system. Choose Mailchimp when email campaigns and straightforward automations are the main job. Choose HubSpot when you want contacts, deals and marketing aligned in one CRM-led workflow and you accept a more complex product surface.
Start from the job, not the logo
Ask:
- Do we mainly need newsletters and promo blasts?
- Do we need behavioural automations (browse abandonment, onboarding drips)?
- Do we need a system of record for sales pipelines?
- How many seats and portals will touch the data?
- What is our monthly send volume and list size?
Mailchimp automation covers practical Mailchimp workflows. Marketing automation and drip campaign ideas apply on either platform when the fundamentals are sound.
Mailchimp in plain terms
Mailchimp built its reputation on email creation, lists/audiences, templates and reporting that non-specialists can use. Over time it added customer path builders, basic CRM-ish contact views, landing pages and ads features. For many SMEs it remains the default “we need email sorted” tool.
Strengths:
- Familiar campaign editor
- Quick to launch newsletters
- Automations for common sequences
- Broad integrations and embeds
Watch-outs:
- Complex sales pipelines are not its core identity
- Costs scale with contacts and features; model your list growth
- Very advanced attribution and multi-team governance may feel cramped compared with full CRM suites
HubSpot in plain terms
HubSpot centres on a CRM database. Marketing Hub email, forms, ads tools and automation sit on that CRM. Sales Hub adds deals and sequences; Service Hub adds tickets. You can start with free CRM tools and paid email/marketing features depending on needs in early 2020 packaging (tiers and limits change; verify current plans when you buy).
Strengths:
- Contact timeline that sales and marketing share
- Workflow automation across lifecycle stages
- Strong reporting culture inside the portal
- Room to grow from marketing into sales ops without a full replatform
Watch-outs:
- Learning curve and configuration debt if you tick every feature
- Price climbs as hubs, contacts and seats grow
- Requires ownership: someone must keep properties and pipelines clean
Email capabilities both should cover
Regardless of vendor, insist on:
- Authenticating domains (SPF, DKIM; DMARC increasingly expected)
- Unsubscribe and preference handling that meets the law in your markets
- List hygiene and bounce handling
- A/B testing for subjects or content
- Templates your brand can stick to
Email deliverability habits matter more than which logo is on the invoice. A perfect tool with a bad list still lands in spam.
Automation differences that matter
Mailchimp: Excellent for classic sequences: welcome series, abandoned browse/cart where ecommerce integrations exist, re-engagement. Visual builders help marketers ship without developers.
HubSpot: Workflows can branch on CRM properties, deal stages and page views with deeper ties to sales activity. Useful when “email” is really “move this contact through a lifecycle that sales can see.”
If your automation dream is mostly promo calendars, Mailchimp is enough. If it is “when deal stage changes, change nurture and alert owner,” HubSpot fits better. For syncing mail tools to CRMs you already own, see email CRM sync.
Pricing posture (how to think, not a quote)
Neither product is “free forever” at serious volume. Estimate:
- Contacts or marketing contacts
- Monthly send volume
- Required seats
- Needed automation features
- Extra hubs (for HubSpot) or premium tiers (for Mailchimp)
Build a 12-month model with list growth. Cheap entry plans that explode at 10k contacts surprise finance teams every year. Add implementation time: HubSpot setups often need more workshop hours; Mailchimp migrations can be faster for email-only teams.
Migration and dual-running
Moving platforms means:
- Exporting audiences with consent status intact
- Recreating templates and automations
- Reconnecting ecommerce and forms
- Updating legal text and footers
- Warming sending reputation on a new domain or subdomain if needed
Do not shut the old tool off on the same day as the first send from the new one without a checklist. Dual-run critical sequences briefly when risk is high.
Team fit
- Solo marketer, email-first: Mailchimp often wins on speed
- Sales + marketing sharing contacts: HubSpot often wins on visibility
- Already deep in another CRM (Salesforce etc.): Either can work as the ESP; integration quality decides. HubSpot wants to be the CRM; Mailchimp is happier as the email layer beside another CRM
Compliance and consent
Store lawful basis / consent flags in the tool you send from, and keep them through imports. Buying lists remains a poor idea regardless of platform. Transactional versus marketing mail may use different sending domains and different tools; do not mix them carelessly.
Creative ops
Whichever tool you pick, create a small template set and a naming scheme for campaigns. Chaos in assets creates chaos in reporting. Shared brand guidelines for email width, logo use and footer legal lines save arguments.
Quarterly cleanup
Every quarter: archive dead automations, remove unused properties, suppress hard bounces, review spam complaint rates and delete duplicate records. Tools feel “broken” when data is dirty more often than when features are missing.
When to revisit the decision
Revisit HubSpot vs Mailchimp when list size crosses a pricing cliff, when sales hires need shared timelines, or when ecommerce attachments become central to revenue. Switching costs are real; switching because of one missing widget is usually wrong, switching because the centre of gravity changed is often right.
Extra practical notes
Take a day to write down your current process before changing tools or structures. The written process reveals which steps are real and which are habit. Share the draft with the people who do the work daily; they will correct assumptions faster than any vendor demo.
After you ship a change, schedule a two-week check: did the metric you cared about move, and did any new failure mode appear? Keep a short changelog so future you knows what was attempted.
FAQ
Can Mailchimp replace a CRM?
For very light needs, maybe. For pipelines, forecasting and multi-user sales process, use a real CRM (HubSpot or other).
Can HubSpot replace Mailchimp for newsletters?
Yes. Many teams send all email from Marketing Hub once configured. Template discipline still required.
Which is better for ecommerce?
Both integrate with major platforms. Compare your exact cart (WooCommerce, Shopify and others) connectors, product block features and abandonment flows on current docs.
Which is better for B2B lead nurturing?
HubSpot usually feels more natural when leads become deals tracked in the same system. Mailchimp can nurture well if sales lives elsewhere and sync is solid.
Choose the centre of gravity
HubSpot vs Mailchimp is really CRM-centred growth versus email-centred marketing. Be honest about which centre you need for the next two years, model cost on real list size and pick the tool your team will actually keep tidy.
