Mailchimp vs HubSpot Marketing Hub: a gradual ladder against a $7-to-$800 cliff

HubSpot Marketing Hub Starter is $7 a month per seat with 1,000 marketing contacts; its Professional tier is $800 a month with 2,000 contacts, 3 core seats and a required one-time $3,000 onboarding fee. Mailchimp climbs gently: Standard is $20 at 500 contacts, $100 for 2,501 to 5,000 and $135 for 5,001 to 10,000, and Premium starts at $350. HubSpot is a CRM with marketing on top, Mailchimp is email software with audiences, and the price gap reflects that difference more than any send volume.

Short answer

Choose Mailchimp when the work is newsletters, welcome flows and campaigns, and the people sending them do not need CRM records. Choose HubSpot when sales and marketing share one contact database and a deal stage should change what email a person gets. Start on HubSpot Starter only if you can live inside 10 automated actions, and budget for the Professional step before you commit.

Two price ladders

HubSpot's figures come from its Marketing Hub pricing page and its Starter and Professional detail pages; Mailchimp's come from its pricing page. All were read on 7 October 2026.

Level	HubSpot Marketing Hub	Mailchimp
Free	Free tools: CRM records for contacts, companies and deals, 1 automated action, up to 2 users	250 contacts, 500 sends a month, 1 seat
Entry	Starter $7/mo per seat: 1,000 marketing contacts, sends up to 5 times contacts, up to 10 automated actions	Essentials $13 at 500 contacts: sends up to 10 times contacts, 3 seats, up to 4 flow steps
Middle	No middle step	Standard $20 at 500; $100 at 2,501 to 5,000; $135 at 5,001 to 10,000; 5 seats, up to 200 flows
Professional	$800/mo: 2,000 marketing contacts, 3 core seats, sends up to 10 times contacts, unlimited automated actions, plus $3,000 one-time onboarding	Premium from $350 at 500 contacts: unlimited users, sends up to 15 times contacts, phone support
Enterprise	$3,600/mo, up to 1,000 workflows, behavioral events	Custom Premium plans above 250,000 contacts

Year one for a three-person team on HubSpot Professional is 12 × $800 plus the $3,000 onboarding fee, $12,600. Mailchimp Premium at 500 contacts is 12 × $350, $4,200, and Standard at 5,000 contacts is $1,200 at list price or $600 on the 50% first-year offer. These are different products with different contact allowances, so the numbers mark the size of the gap and do not prove one tool better. HubSpot's page gives no price for extra marketing contacts beyond those included, so a 5,000-contact list needs its own quote.

Automation limits are the real tier gate

HubSpot sells automation by the action. The pricing table lists 1 automated action on Free, up to 10 on Starter, and unlimited actions with omni-channel automation from Professional, which lists up to 300 workflows for 10 teams. Enterprise raises that to up to 1,000 workflows for 300 teams and adds behavioral events and predictive lead scoring. A SaaS that wants a three-step onboarding sequence and a trial-ending reminder can fit them into 10 actions only with care, since each branch and delay can count.

Mailchimp's limit is plan-based: up to 4 flow steps on Essentials, up to 200 flows on Standard and Premium. That is a much lower ceiling on complexity at a much lower price, but without HubSpot's lead scoring or CRM-triggered paths.

Seats against contacts

HubSpot Starter is priced per seat, and Professional includes 3 core seats with additional seats starting at $45 a month. Mailchimp includes seats in the plan: 3 on Essentials, 5 on Standard, unlimited on Premium. If six people need to edit emails, that is $45 × 3 = $135 a month extra on HubSpot Professional against nothing extra on Mailchimp Premium. If only one person ever logs in, HubSpot Starter at $7 undercuts Mailchimp Standard's $20 on the sticker while allowing twice the contacts of Mailchimp's 500-contact starting band.

What HubSpot's price buys beyond email

A shared contact database. The free tier already lists a unified view of contacts, companies and deals, with two-way data sync with dozens of apps. Email sits on top of that database, so a deal moving to "closed lost" can end a sequence.
Marketing tooling by tier. Starter lists segments built from your data and targeted email campaigns. Professional adds advanced automation, social account management and campaign planning in Marketing Studio. Enterprise adds team hierarchy, a sandbox and email approvals.
Mailchimp's advantages. Standard allows up to 5 audiences, custom-coded templates that can be sent, an events trigger for flows, and a free plan for testing.

For a SaaS: events and billing

HubSpot's pricing page puts behavioral events in its Enterprise column, which starts at $3,600 a month. Mailchimp's Events endpoint can start a flow on any paid plan, single-step on Essentials and multi-step on Standard, for contacts already in the audience. Neither page lists a Stripe or Paddle connector, so a trial-ending or failed-payment webhook would reach either tool through your own handler. Treat that handler as the integration work in both cases, and decide whether the CRM or the email tool is the system of record for plan status.

Moving across

Decide which contacts will actually be mailed before you import. HubSpot's tiers are built on marketing contacts and Mailchimp's on contact bands, so a trimmed list costs less on both.
Export with unsubscribe and bounce status; import them as suppressed.
If you take Professional, schedule the onboarding it requires before you rebuild sequences.
Run the old and new welcome flows side by side for a cycle, then cancel.

Which to choose

Mailchimp Standard for campaign email at $20 to $135 a month across 500 to 10,000 contacts.
HubSpot Starter for a founder who wants a CRM and basic email at $7 a seat, within 10 automated actions.
HubSpot Professional for a sales-led SaaS with a marketing owner, 3 or more seats and a budget of about $12,600 in year one.

Mailchimp vs HubSpot: common questions

How much does HubSpot Marketing Hub cost compared with Mailchimp?

HubSpot lists Starter at $7 a month per seat, Professional at $800 a month and Enterprise at $3,600 a month, plus free tools. Professional carries a required one-time onboarding fee of $3,000. Mailchimp lists Essentials at $13, Standard at $20 and Premium at $350 a month at 500 contacts, with Standard bands of $100 at 5,000 contacts and $135 at 10,000.

Is HubSpot worth it for email alone?

Rarely. If the job is sending newsletters and a welcome sequence, Mailchimp Standard at $100 for up to 5,000 contacts does it for $1,200 a year at list price. HubSpot starts paying for itself when email has to reference CRM records, deal stages and owners, which is the case for a sales-led SaaS.

What limits HubSpot Starter?

Its page lists 1,000 marketing contacts, a send limit of 5 times your contact tier, and up to 10 automated actions. Professional lifts that to unlimited actions, 2,000 marketing contacts and a 10-times send limit. The step from $7 per seat to $800 a month is the main budgeting hazard.

Which handles product events for a SaaS?

Mailchimp's Events endpoint starts a flow from any paid plan (multi-step from Standard) for contacts already in the audience. HubSpot's pricing page ties behavioral events to its Enterprise column. In both cases your own server has to convert billing webhooks into events, since neither page lists a Stripe or Paddle connector.
