Mailchimp Review 2026: Pricing, Limits and Who It Fits

Mailchimp prices by the number of contacts in your account. Each paid plan's monthly send allowance is a multiple of your contact tier: 10x on Essentials, 12x on Standard, 15x on Premium. Test emails and transactional emails count toward that allowance. All prices below are Mailchimp's US list prices in USD on monthly billing, from Mailchimp's pricing page on Oct 7, 2026.

Discounts and billing terms:

• Introductory discount: Mailchimp shows 15% off for the first 12 months on plans with 10,000 or more contacts. For example, Essentials at 10,000 contacts would be $93.50/mo for the first year (our calculation from the $110 list price), then $110. Below 10,000 contacts there's no discount, even though the page shows "for 12 months" next to the price.
• Annual billing: offered only on Standard and Premium at 10,000+ contacts, through Mailchimp's sales team. No annual price is published.
• Free trial: 14 days of Essentials or Standard for new accounts. A trial without a card on file can send only 100 emails.
• Nonprofits: a 15% discount on request.
• Pay As You Go: prepaid email credits (1 credit = 1 send) that expire after 12 months, with Essentials features. Mailchimp shows credit prices only in-app, so we haven't listed them.

What it costs to run the same program at four list sizes

Example only. Our calculation from Mailchimp's list prices above. Assumptions: monthly billing, US pricing, no introductory discount, one audience, and no unsubscribed or non-subscribed contacts in the count. Program: four campaigns a month to the whole list plus a welcome series and one abandoned-cart or re-engagement flow. Four campaigns use 4x your contact count, which fits inside the 10x allowance on Essentials.

Most surprise bills start here. On Mailchimp's current plans:

Three rules to know:

1. The same person in two audiences counts twice. Mailchimp's own example: an address in two audiences is billed as two contacts. Use one audience with tags or groups instead.
2. You're billed on your peak. Mailchimp bills on the highest contact count during the billing period. Archiving contacts after a spike doesn't lower that period's bill.
3. Going over your tier on a paid plan doesn't stop your sending. Mailchimp adds "add-on contact blocks" to your bill instead. It doesn't move you to the next tier automatically; you change tiers yourself. On the Free plan, going over 250 contacts pauses sending until you upgrade or remove contacts.

The practical fix: archive unsubscribed and long-inactive contacts on a schedule, and don't import non-subscribed store customers you don't plan to email. Mailchimp's legacy plans (accounts on pricing from before May 15, 2019) follow different rules. If you're on one, check your billing page before changing anything.

The Free plan includes 250 contacts, 500 sends a month (no more than 250 a day), 1 audience and 1 user seat. According to Mailchimp's plan comparison, it doesn't include email scheduling, A/B testing, removal of Mailchimp branding, or SMS, and automation flows are shown only as a preview. Email support lasts for the first 30 days.

The limits were 500 contacts and 1,000 sends a month until late 2025. Mailchimp's help center showed the new limits by December 2025. Abandoned-cart email and the one-click welcome email have since dropped off the Free feature list.

Who it's still good for: testing Mailchimp's editor, or a very small list that mails once or twice a month. Anyone who wants a free plan to grow on should compare the best free email marketing plans.

When to move up:

• Essentials → Standard: when you need a real automation (welcome, nurture and abandoned-cart flows with branches) rather than a 4-step sequence, or when you need transactional email from the same account.
• Standard → Premium: usually only for teams that need unlimited seats and audiences, phone support or SSO. The jump at 10,000 contacts is $135 to $350 a month.

Mailchimp's automation builder is called Marketing Automation Flows. On Essentials you can build flows of up to four steps plus single-email automations such as a welcome email. Standard opens up to 200 flows with multiple starting points and branching, which covers welcome series, lead nurture, abandoned cart (with a connected store), post-purchase and re-engagement.

Standard also adds predictive segments (likelihood to purchase, customer lifetime value) and send-time optimization. Teams that need lead scoring, a sales pipeline or deep conditional logic tied to a CRM usually outgrow it. That's where ActiveCampaign and HubSpot compete; see Mailchimp vs ActiveCampaign.

• Shopify: Mailchimp now uses its own "Mailchimp for Shopify" app; the old legacy app has been retired. According to Mailchimp's documentation, it syncs customers, orders, subscription status, optional customer tags and B2B company data, plus events such as product viewed, added to cart, checkout started and checkout completed, in near real time. One store connects to one audience. If you're moving off the legacy app, Mailchimp notes that the abandoned-cart email series doesn't migrate; rebuild it in the new app.
• WooCommerce: the official Mailchimp for WooCommerce plugin syncs customers and orders and supports abandoned-cart automation. Abandoned cart needs non-opted-in customer syncing turned on, and those non-subscribed contacts then count toward your bill.

• SMS: a paid add-on for Essentials and above, after Mailchimp approves your application. It's available in the US, Canada, the UK, Australia and about 30 European countries. Credits are a monthly subscription that renews automatically, and unused credits expire each cycle. In the US, one SMS uses one credit, and Mailchimp's pricing data lists 1,000 credits at $20/month.
• Transactional email (formerly Mandrill): an add-on for Standard and Premium only; Essentials isn't eligible. It's sold in blocks of 25,000 emails at $20 per block for the first 20 blocks, with lower block prices at higher volume. A dedicated IP for transactional sending is $29.95/month.

We don't publish inbox-placement scores for Mailchimp because BestSends hasn't run a documented placement test on it. Here's what Mailchimp documents:

• Domain authentication uses two CNAME records (DKIM) and one TXT record (DMARC), with an automated setup option. You can't authenticate a free-mail address such as a Gmail address as your sender.
• Gmail and Yahoo bulk-sender rules (in force since February 2024) require authentication and a published DMARC record if you send more than 5,000 emails a day to their users, plus one-click unsubscribe and a low spam-complaint rate. Mailchimp says unsubscribe handling is built into its campaigns and recommends DMARC for every sender.
• Cleaned (hard-bounced) contacts are removed from sending and don't count toward billing.

What actually decides your inbox placement on any platform is your list quality, engagement and authentication. See DMARC and DKIM.

Two practical notes:

• Export before you delete. Mailchimp says deleting an account is permanent and removes audience, campaign and report data. You can pause instead (3 or 6 months, twice a year).
• Mailchimp limits account exports to one per 24 hours, and contact export files expire after 30 days.
