Mailchimp Review for Ecommerce Sellers

What is Mailchimp?

Mailchimp is a general email marketing platform that works with any website, and it has the most recognisable name in the category. The free plan's real numbers matter more than its reputation though, and one of them is inconsistent even on Mailchimp's own site. The free plan is 250 contacts, 1 audience and 1 seat, and it excludes marketing automation flows entirely — that part is unambiguous. The monthly send allowance is not: Mailchimp's plan-comparison page states it twice with two different figures, once as 500 sends a month with a 250 daily limit and once as 1,000 sends with a 500 daily limit. Since it is the same page, we are not going to pick one for you — plan for the lower number and confirm it in the account before you commit. Two further things worth knowing: the paid plans start at the 501-contact tier, so a free-plan store that outgrows 250 contacts cannot buy the next tier up, and Mailchimp also sells a 14-day trial of Essentials or Standard that is capped at 100 sends until you add a card.

Pros and cons

Free plan and pricing

Free plan

A permanent free plan at 250 contacts, 1 audience and 1 seat, with no time limit and no card required. It excludes automation flows, so abandoned cart emails are not possible without upgrading. One caveat on the send allowance: Mailchimp's plan-comparison page gives it twice with two different figures — 500 sends a month with a 250 daily limit in one tooltip, and 1,000 sends with a 500 daily limit in another on the same page. Treat 500 as the number to plan against.

• 250 contacts
• 1 audience
• 1 seat
• No marketing automation flows
• No email scheduling or A/B testing
• Free-plan email support for the first 30 days only
• Monthly send allowance: stated as both 500/month (250/day) and 1,000/month (500/day) on Mailchimp's own plan-comparison page — plan for 500

Plans

Pricing in detail

Mailchimp publishes four marketing plans. Free is $0 with 250 contacts and 1 audience. The three paid plans share the same smallest contact tier — 0 to 500 is the lowest the selectors go on both the pricing page and the plan-comparison page — and each plan multiplies sends by your contact count, not by a fixed number: Essentials is 10 times your maximum contact count, Standard is 12 times, and Premium is 15 times. Two things make the paid prices harder to quote than other tools on this site: the cost depends on your contact tier, and Mailchimp shows prices in your local currency. When we checked, the 0-500 contact tier showed Essentials at HK$94/month and Standard at HK$143/month, and the page listed a promotional rate on Standard of $10/month for 12 months, then from $20/month. Check the pricing page with your own currency and contact count selected.

What we checked in the product

• 2026-11-06: Signed up for the free plan with Google and worked through the onboarding. The last step, 'You've got a head start on your setup', requires a street address or PO box before the account opens: the page states 'A few address details are missing. Add them to continue', its 'Skip for now' button is disabled, and opening the app directly redirects straight back to the same step. The reason is printed on the form — to follow anti-spam laws, the address appears in the footer of every email you send. Watch the prefilled fields, too: Mailchimp guessed our city as Denver, Colorado 80219 from the website we entered, which was simply wrong, and would have been saved had we clicked 'Looks good' without reading. We stopped at this step rather than put a real address into a test account, so the in-product limits in this review are from the published plan terms, not from a finished account.

  

Who should use Mailchimp?

• Sellers who mainly send newsletters rather than automated flows
• Stores with a list under 250 contacts
• Merchants who want an email tool independent of their store platform
• Beginners who want a familiar interface and plenty of documentation

Who should avoid Mailchimp?

• Stores that need abandoned cart or welcome automations on the free plan
• Sellers with a list larger than 250 contacts who cannot pay yet
• Stores with a list between 251 and 500 contacts, because there is no paid tier small enough to buy
• Anyone who needs a fixed, easily predictable monthly bill

Alternatives

If Mailchimp is not the right fit, compare these alternatives:

• Omnisend
• Klaviyo

Final verdict

Mailchimp's advantage is that it works with any store and needs no platform connection, which makes it a safe default if you are not on Shopify. For ecommerce specifically the free plan is weaker than it looks: 250 contacts, 1 audience and 1 seat, with no automation flows at all. The last point is the one that matters, because a welcome email and an abandoned cart sequence are the two highest-return emails a small store can send, and neither is possible on the free plan. Two details are easy to miss. The paid plans start at 501 contacts, so a store that outgrows 250 contacts has no 251-to-500 tier to buy — it jumps straight to a tier sized for several hundred. And the free plan's send allowance is inconsistent on Mailchimp's own comparison page, quoted as both 500 and 1,000 sends a month; plan for 500. Omnisend's free plan includes automation, so if ecommerce automation is the goal, compare those two free plans before choosing on brand recognition.
