Mailchimp

What is Mailchimp?

Mailchimp is an email marketing platform founded in 2001 by Ben Chestnut and Dan Kurzius in Atlanta, Georgia. It grew to become the most recognized brand in small-business email marketing before Intuit acquired it for $12 billion in 2021. As of 2025, Mailchimp serves over 12 million customers across 175 countries and remains the default first platform for teams sending their first email campaign.

The product covers email creation, audience management, basic automation, landing pages, and campaign analytics. Its free tier — 500 contacts, 1,000 monthly sends — is the most accessible entry point in the 80/20 of email marketing tools we cover. The Intuit acquisition added QuickBooks sync and financial data workflows, shifting the platform toward small-business general marketing rather than pure email.

Mailchimp integrates with Shopify, WordPress, and Zapier, covering the most common small-business tech stacks. For teams with simple sending needs — one newsletter a week, a welcome sequence, a basic abandoned-cart email — Mailchimp works without configuration complexity.

How does Mailchimp work?

Mailchimp organizes its product around three components: audiences, campaigns, and automations. Understanding these three tells you whether Mailchimp’s architecture fits your sending model.

Audiences and segmentation

Every contact in Mailchimp lives in an Audience. Tags, groups, and segment filters let you target subsets — buyers who spent over $100, subscribers who opened the last three campaigns, contacts added in the past 30 days. The segmentation tools work well for behavioral and purchase-based splits on lists under 25,000 contacts.

Larger lists or more complex conditional logic starts to strain Mailchimp’s interface. A contact who belongs to multiple segments generates separate records if you manage multiple Audiences — a structural limitation that competitors like Klaviyo resolve with a unified profile model. This audience structure is the most common source of confusion for teams migrating off Mailchimp.

Campaign builder and templates

Mailchimp’s drag-and-drop campaign builder uses a block-based editor with 100+ pre-built templates. Non-designers can produce professional-looking emails without touching HTML. The builder supports A/B testing for subject lines, from names, send times, and content variations — the test logic is basic but functional for most use cases.

The template library skews toward retail, events, and non-profit fundraising. For B2B newsletters or content-first publications, the templates are a starting point that requires customization. Teams sending plain-text newsletters don’t benefit from the builder at all and may find simpler tools like ConvertKit better suited.

Automation sequences

Mailchimp’s automations — called Customer Journeys — support trigger-based sequences: welcome emails on subscribe, birthday messages, post-purchase follow-ups, and abandoned cart reminders. The visual builder lets you connect steps with timing delays and conditional branches.

The automation builder covers the most common use cases but lacks the depth of Klaviyo’s flow system. Conditional splits based on predicted lifetime value, purchase frequency scoring, or multi-channel attribution require workarounds in Mailchimp. For teams whose automations stay close to standard playbooks, the Customer Journey builder is sufficient.

How does Mailchimp compare to Klaviyo, Brevo, and ConvertKit?

Mailchimp leads on name recognition and free-tier generosity. Klaviyo leads on ecommerce depth and flow logic. Brevo leads on contact-volume pricing for high-count lists. ConvertKit leads on creator-focused email and paid newsletter tools. The table below shows the trade-offs across the four tools at comparable price points.

Attribute	Mailchimp	Klaviyo	Brevo	ConvertKit
Best for	Simple sends, first campaigns	Ecommerce email + SMS	High-volume senders, EU teams	Creators, paid newsletters
Free tier	500 contacts, 1K sends/month	250 contacts, 500 sends/month	Unlimited contacts, 300 sends/day	10,000 subscribers, unlimited sends
Ecommerce depth	Basic	Best in category	Moderate	Minimal
Automation quality	Moderate	Strongest	Good	Creator-focused
Pricing at 10K contacts	~$110/month	~$150/month	~$25/month	~$100/month
GDPR / EU data hosting	US-hosted	US-hosted	EU-hosted option	US-hosted
SMS marketing	Yes (paid add-on)	Yes (native)	Yes (paid add-on)	No
80/20 verdict	Use if you’re just starting	Use for Shopify / ecommerce	Use for high contact counts	Use for creator newsletters

“Mailchimp’s brand name gets you through procurement conversations faster than any competitor — but that’s a people problem, not a product problem,” said Marcus Reed, Go-to-Market Editor at tools8020 and a former demand-generation manager at a Series B SaaS company.

Who uses Mailchimp in 2026?

Mailchimp’s primary user base is small businesses, local retailers, non-profits, and teams launching their first email program. A photography studio sending a monthly newsletter, a restaurant promoting weekly specials, a charity running a year-end fundraiser — these are the use cases Mailchimp handles without friction.

The Intuit acquisition added a meaningful segment of small businesses that already use QuickBooks and want email marketing connected to their financial data. A florist tracking which email campaigns drove their highest-margin orders through connected revenue attribution is a realistic Mailchimp success case.

Mailchimp also covers a portion of the agency market — digital marketing agencies managing email for multiple clients prefer Mailchimp’s multi-account management and white-label options. The brand’s recognition reduces the time agencies spend explaining the tool to clients who are unfamiliar with email platforms.

When should you skip Mailchimp?

Mailchimp is the wrong choice in four specific scenarios. Choosing an alternative before you outgrow Mailchimp avoids a painful migration.

• You sell products on Shopify or WooCommerce. Use Klaviyo instead. Klaviyo’s ecommerce integrations, predictive analytics, and flow logic are purpose-built for retail email. Mailchimp’s ecommerce features are functional but secondary.
• Your list exceeds 10,000 contacts. Mailchimp’s pricing grows faster than competitors at higher contact volumes. Brevo charges by sends, not contacts — at 50,000 contacts sending two campaigns per month, Brevo costs significantly less.
• You need conditional multi-step automations. Complex workflows with branching logic based on engagement, purchase history, or predicted lifetime value need Klaviyo or ActiveCampaign. Mailchimp’s Customer Journey builder doesn’t support this depth cleanly.
• You’re a creator building a paid newsletter. ConvertKit has paid subscriber management, recommendation networks, and a creator-first product model that Mailchimp doesn’t match.

How much does Mailchimp cost?

The free tier covers 500 contacts and 1,000 sends per month — enough for a small newsletter or a single welcome sequence. Paid plans start at $13 per month and scale with contact count. At 10,000 contacts, expect to pay roughly $110 per month on the Standard plan.

Plan	Price (monthly billing)	Key inclusions
Free	$0	500 contacts, 1,000 sends/month, basic templates
Essentials	$13/month	500 contacts, 5,000 sends, 3 audiences, A/B testing
Standard	$20/month	500 contacts, 6,000 sends, Customer Journeys, behavioral targeting
Premium	$350/month	10,000 contacts, unlimited sends, advanced segmentation, phone support

Pricing verified at mailchimp.com/pricing on 2026-05-24. Pricing scales by contact count — a Standard plan at 10,000 contacts runs approximately $110/month, and at 50,000 contacts approximately $400/month. Annual billing saves roughly 10–15%.
