For a small business whose main job is sending newsletters and promotions, Mailchimp is the cheaper and simpler choice, and HubSpot email pays off only when your emails need to be tied to a CRM, deal stages, and sales follow-up. That is the short verdict from comparing documented plans, published pricing, and the patterns that verified user reviews repeat. Mailchimp is an email platform with CRM features added on. HubSpot is a CRM with email attached, and that difference decides almost everything below.
The upgrade question is really a cost question. Mailchimp lists paid plans from roughly $13 a month (Essentials) and $20 a month (Standard), scaling with contact count. HubSpot's free tools include basic email, and its paid Marketing Hub starts low per seat but climbs steeply once you need automation at scale. Prices change often and third-party sources disagree, so verify current numbers on each vendor's pricing page before you commit.
This comparison is built from documented evidence only. We did not run live campaigns through either account, so treat the verdicts as a reading of the published facts, not a lab result.
How We Compared These Email Platforms
We compared both tools using each vendor's public pricing pages, documented feature lists, and recurring themes in verified reviews on major software directories. The same yardstick was applied to each: documented price at realistic contact counts, what automation each plan includes, how contact data is stored, what reporting looks like, and how hard it is to leave. We did not send campaigns, build automations, or import lists in either product. Where sources disagreed on a price, we say so and recommend checking the vendor.
The two products target different buyers. Mailchimp's documented focus is campaign creation for small businesses and ecommerce stores, with templates, audience segmentation, and a landing page builder. HubSpot's Marketing Hub is documented as part of a wider platform, so email sits next to forms, lead scoring, a contact database, and sales tools that share the same record for each person.

Pricing at Realistic List Sizes
Mailchimp documents four tiers: Free, Essentials, Standard, and Premium. Several 2026 pricing guides list Essentials from about $13 a month, Standard from about $20 a month, and Premium from about $350 a month, all rising with contacts. One guide puts Standard at roughly $100 a month for 10,000 contacts. Mailchimp bills on total contacts, including unsubscribed and non-subscribed ones in some configurations, which is a frequent complaint in reviews, so list hygiene matters.
HubSpot's picture is harder to pin down. The free plan covers basic marketing email with branding and sending limits. Marketing Hub Starter is documented at a low per-seat price, with sources in 2025 and 2026 quoting figures between about $9 and $20 per seat per month for a small contact allowance. The jump comes at Professional, which is documented in the hundreds of dollars per month and typically carries an onboarding fee. If your goal is a real automation engine with branching workflows, expect Professional, and expect it to cost far more than Mailchimp Standard.
| Item | Mailchimp | HubSpot Email |
|---|---|---|
| Entry paid price (verify current) | About $13 to $20 a month | Roughly $9 to $20 per seat a month (Starter) |
| Free plan | Yes, limited contacts and sends | Yes, basic email with HubSpot branding |
| Real automation tier | Standard, about $20 and up | Professional, hundreds per month |
| Pricing driver | Contact count | Seats plus marketing contacts |
| Built-in CRM | Light audience profiles | Full CRM with deal tracking |
| Best for | Newsletters and ecommerce promos | Lead nurturing tied to sales |
Automation, Segmentation, and Templates
Mailchimp's Customer Journey Builder is documented as requiring the Standard plan or above, and it covers welcome series, abandoned cart emails, and date-based sends. Segmentation is based on tags, purchase behavior, and engagement. Reviewers consistently praise the template library and the editor, and they consistently complain that the platform feels heavier and more upsell-driven than it used to. If you want a deeper look, read our Mailchimp review.
HubSpot's workflows are documented as more flexible, with branching on contact properties, deal stage, form submissions, and page visits. That matters when the email is a step in a sales process, for example a nurture sequence that stops the moment a rep logs a call. The documented trade-off is complexity: reviewers often say the platform takes longer to learn and that useful features sit behind higher tiers. Our HubSpot Marketing Hub review covers those tiers in more depth.
When the Upgrade to HubSpot Pays Off
Moving to HubSpot makes sense when three conditions are true at once. First, someone other than the marketer needs to see email engagement, usually a salesperson following up on leads. Second, you already pay for, or plan to adopt, a CRM and would otherwise sync two systems. Third, your campaigns depend on behavior beyond email opens and clicks, such as page visits or form fills tied to a contact record.
If none of those apply, the upgrade mostly adds cost. A shop sending a weekly newsletter and a few promotions gets little from a shared CRM record. A services firm that books sales calls from email replies gets a great deal. The usual pattern in reviews is that HubSpot delights teams that use its CRM and frustrates teams that buy it only for email.
Switching Costs and Data Portability
Both platforms document contact export to CSV, so moving a list is straightforward in either direction. The harder parts are rebuilding automations, templates, and forms, none of which transfer automatically. Plan for a rebuild of every journey and a re-check of consent records. Moving from Mailchimp to HubSpot also means mapping Mailchimp tags to HubSpot properties, so decide your field structure before importing. Moving the other way is simpler, because Mailchimp's data model is lighter, but you lose the CRM history attached to each contact.
One practical tip from reviewer patterns is to run the new platform in parallel for a few weeks before cutting over, and to keep your sending domain authentication consistent so deliverability does not reset. For related head to heads, see Mailchimp vs ActiveCampaign for an automation focused alternative.
Who Should Pick Which
Choose Mailchimp if you run a small team, send mostly broadcast email, sell products online, and want predictable monthly costs. Choose HubSpot if sales and marketing share contacts, you value one record per customer, and you can justify the higher tiers. Teams stuck in the middle, wanting automation without a CRM, often look at other tools too, so it is worth reading a few alternatives before paying for an upgrade.
A final warning applies to both: list growth changes the bill quickly. Price the plan at the contact count you expect in twelve months, not the count you have today, and check whether inactive contacts count toward your tier.
The bottom line: choose Mailchimp for email-first small businesses and upgrade to HubSpot only when you genuinely need a CRM driving your campaigns, because paying for the platform just for email rarely pays off.
