Mailchimp is an email marketing and automation platform that stores your subscriber list, builds and sends campaigns, runs automated follow-up sequences, and reports on what those messages produced. It is among the most recognized names in the category, it has been owned by Intuit since 2021, and it charges by the number of contacts you store rather than the number of emails you send. That pricing model decides more about whether the platform is a good deal for your business than any feature listed on its marketing pages. This is the first deep dive in our platform-by-platform series, and it starts with the tool most people try first.
From an Atlanta Side Project to an Intuit Product
Ben Chestnut and Dan Kurzius ran a web design agency called The Rocket Science Group, aimed at large corporate clients. On the side, they built an email tool for small businesses. Founded in Atlanta in 2001, it was positioned as an alternative to the oversized and expensive email software of that era, giving small operators access to capabilities their larger competitors already had (Mailchimp’s own company history). Two decades later it had grown into a global operation headquartered in Atlanta.
The ownership changed on November 1, 2021. Intuit, the company behind TurboTax, QuickBooks, and Credit Karma, closed its acquisition for roughly $5.7 billion in cash plus 10.1 million shares valued at about $6.3 billion, plus restricted stock units, with a further $200 million in stock granted to employees after closing (Intuit’s own transaction announcement). The stated logic was integration: connect QuickBooks purchase data to marketing so a small business could segment customers by what they actually bought.
That history matters to a buyer for one practical reason. The product is no longer an independent small-business tool setting its own terms. It is a business unit inside a large public company, and its packaging has moved accordingly.
What the Platform Actually Does
The product covers six jobs.
- Audience management: storing contacts, importing them, tagging them, and slicing them into segments. Mailchimp calls a stored list an “audience,” and how many audiences you get is a plan-level limit.
- Campaign creation and sending: a drag-and-drop editor, a template library, and the sending infrastructure that gets the message into inboxes at scale.
- Automations: multi-step sequences triggered by behavior, such as a welcome series or an abandoned-cart reminder. These were called Customer Journeys until June 2025, when the feature was renamed Marketing Automation Flows. Older reviews still use the old name for the same thing.
- Landing pages, forms, and popups: the capture side of the funnel, so subscribers can sign up without a separate tool.
- Light CRM and segmentation: contact profiles, engagement history, and behavior-based segments. It is a marketing database, not a sales pipeline.
- Reporting: opens, clicks, unsubscribes, and for connected stores, revenue attributed to campaigns.
Around that core sit add-ons: SMS marketing credits on paid plans, Mailchimp Transactional for developer-triggered messages like password resets and order confirmations, generative AI content tools on the higher tiers, and a directory of more than 300 integrations covering e-commerce, booking, analytics, and support tools.
If the automation half of that list is new to you, our beginner’s guide to marketing automation explains the workflows these features are built to run, and it is worth reading before you evaluate any plan on automation capability alone.
Who It Is For
The natural fit is a small or mid-sized organization sending campaigns to a list in the hundreds or low thousands, with nobody on staff whose full-time job is email. Service businesses, local retailers, nonprofits, associations, professional practices, and small publishers all land here. The editor is genuinely approachable, the templates are decent out of the box, and a competent generalist can send a good-looking campaign on day one without training.
It is also, for many organizations, the first marketing tool they ever buy, which makes it an entry point into the wider discipline covered in our post on why marketing is important.
Where the fit weakens is at the specialist end. A store doing serious monthly revenue, a B2B company running lead scoring against a sales team, or a marketer who wants deeply branched conditional logic will find the ceiling sooner than expected.
How Mailchimp Pricing Works
Four marketing plans, priced by contact tier. The figures below were checked on the vendor’s pricing page and plan documentation on July 26, 2026, in US dollars on monthly billing. Verify them before you budget, because this vendor changes them often.
| Plan | Starting price | Contact ceiling | Monthly sends |
|---|---|---|---|
| Free | $0 | 250 contacts | 500 per month, 250 per day |
| Essentials | from $13 at 500 contacts | 50,000 contacts | 10x your contact limit |
| Standard | from $20 at 500 contacts | 100,000 contacts | 12x your contact limit |
| Premium | from $350, base includes 10,000 contacts | 200,000 contacts | 15x your contact limit |
Three mechanics behind that table are easy to miss and expensive to learn late.
First, the billable contact count includes unsubscribed and non-subscribed contacts. Only archived, cleaned, and deleted contacts drop off the total. You can pay for people who have already opted out.
Second, going over a limit does not stop your sending on a paid plan. It adds an "add-on contact block" charge to the bill automatically, and one block carries its own proportional send allowance (Mailchimp’s overage documentation). On the Free plan the behavior differs: exceed 250 contacts and sending is held until you upgrade or shrink the list.
Third, billing uses your peak contact total during the cycle. Prune the list mid-month and the bill still reflects the highest number you stored.
Two side doors exist. A Pay As You Go option sells email credits instead of a subscription, with the Essentials feature set, which suits genuinely infrequent senders. And registered nonprofits and charities can request a 15% discount.
The Tradeoffs Worth Knowing
The free plan is now very small. At 250 contacts and 500 sends per month, with a 250-per-day cap, it is a demo rather than a working plan for most businesses. It includes one audience, one seat, a limited template selection, a one-click automated welcome email, and basic reporting. It does not include email scheduling, and Mailchimp branding stays on your emails.
Automation is tiered, and the tier that matters is not the cheapest one. The Free plan gives only a preview of the multi-step automation builder rather than full access. Essentials caps automation flows at four steps. The genuinely useful builder, with up to 200 flows plus prebuilt templates and advanced segmentation, begins at Standard. If you are buying this platform because you want automation, Essentials is usually the wrong purchase.
Cost scales with list size, not with usage. A dormant subscriber costs the same as your best customer, so a business holding 10,000 contacts and mailing them quarterly pays for storage it barely uses. The Premium tier’s base price of $350 per month at 10,000 contacts shows how quickly the curve steepens. Send-volume pricing, which competitors such as Brevo use, inverts that math. Our pillar guide on choosing an email marketing platform works through how to match the model to your sending pattern, and that single check often changes which tool is cheapest for a given business by a wide margin.
Feature depth trails the specialists. For an online store, Klaviyo’s behavioral segmentation and revenue attribution go further. For branched, condition-heavy workflows tied to a sales pipeline, ActiveCampaign’s builder and built-in CRM go further. Mailchimp is broad rather than deep, which is exactly right for a generalist and exactly wrong for a specialist.
There are hard ceilings. Essentials stops at 50,000 contacts, Standard at 100,000, Premium at 200,000. Past that you are negotiating a custom plan with a sales team.
How to Decide Whether It Fits
Start with your list size and sending pattern together. Multiply your contact count by your plan’s send multiplier and check whether the result covers a normal month. If you hold a large list and mail it rarely, contact-based pricing is working against you and a send-based competitor deserves a look.
Next, be honest about how much automation you need. If the answer is a welcome email and an occasional newsletter, the entry tiers are fine. If the answer is behavior-triggered sequences with real branching, price the Standard plan from the start rather than budgeting for Essentials and upgrading three months later.
Then check the one integration your business depends on, whether that is your store, your booking system, or your accounting software. If you already run QuickBooks, the Intuit ownership is a genuine advantage, since the purchase-data connection is the reason the acquisition happened.
Finally, use the trial. Standard and Essentials both offer 14 days, and signing up without a credit card caps you at 100 emails, enough to judge the editor and the reports with your own content. Whether marketing automation is worth paying for at all is a prior question, and our post on whether automation is the right move for your business is the better place to settle it.
Frequently Asked Questions
Is Mailchimp free?
There is a free plan, but it is small. As of July 2026 it allows 250 contacts and 500 sends per month, with a daily cap of 250 sends, one audience, one seat, and basic reporting. It does not include the multi-step automation builder or email scheduling, and your emails carry Mailchimp branding. Exceed 250 contacts and sending is paused until you upgrade or reduce the list.
Who owns Mailchimp?
Intuit, the company behind TurboTax, QuickBooks, and Credit Karma. The acquisition closed on November 1, 2021 for total consideration of roughly $5.7 billion in cash plus about $6.3 billion in Intuit stock and restricted stock units. The product still operates under the Mailchimp brand and is often written as Intuit Mailchimp.
How much does it cost as my list grows?
Pricing is set by contact tier. Paid plans start at $13 per month for Essentials and $20 per month for Standard at 500 contacts, and Premium starts at $350 per month with 10,000 contacts included. Because every stored contact is billable, including unsubscribed ones, the bill tracks list size rather than how much email you send. Check the current tier calculator before budgeting, since these figures change.
What counts as a contact for billing?
Subscribed, unsubscribed, and non-subscribed contacts all count toward your total. Archived, cleaned, and deleted contacts do not. Billing also uses the peak contact total during the billing cycle, so trimming your list mid-month does not lower that month’s charge.
Does the Free plan include automation?
Not the real builder. The Free plan includes a one-click automated welcome email, and that is the limit. The Essentials plan adds automation flows capped at four steps. Multi-step flows with prebuilt templates and advanced segmentation start at the Standard plan.
What happened to Customer Journeys?
The feature was renamed Marketing Automation Flows in 2025. It is the same visual automation builder under a new label. Reviews, tutorials, and third-party documentation published before that date will still call it Customer Journey Builder.
When should I choose something else?
Three signals. If you run an e-commerce store where most of your marketing depends on purchase behavior, a store-native platform like Klaviyo usually earns its premium. If your sequences need heavy conditional branching tied to a sales pipeline, ActiveCampaign goes deeper. And if you hold a large list you mail infrequently, a send-based pricing model will almost always cost you less.
Is it a good choice for a nonprofit?
It is a common one. The interface suits volunteer or part-time staff, the template library covers newsletters and appeals well, and registered nonprofits and charities can request a 15% discount by contacting the billing team after signing up. The contact-based pricing caveat still applies: a large donor list that receives occasional mailings is the pattern this model charges the most for.
