MailerLite vs Mailchimp: Which Is Better for a Small Business?

The short answer: for most small businesses, MailerLite wins on price and simplicity — it’s 30–50% cheaper at nearly every list size, bills only active subscribers, and has the more usable free plan. Mailchimp wins when you need its ecosystem: 300+ native integrations, predictive e-commerce segmentation, multivariate testing, and SMS in the same account. The decider isn’t features; it’s whether you’ll actually use what Mailchimp’s premium buys.

The mechanism that actually decides this: same billing axis, different generosity

Unlike some comparisons, MailerLite and Mailchimp bill on the same axis: list size. Your subscriber/contact count sets your tier on both platforms. So there’s no inverted cost curve to exploit — MailerLite is simply cheaper at almost every tier, and the real question is where the hidden money leaks are.

Think of each platform’s bill as three parts: the sticker price for your tier, what counts toward the tier, and the send cap attached to it.

• MailerLite bills by active subscriber — unsubscribed and bounced contacts don’t count. Comfort plans cap sends at 10× your subscriber tier per month; Power plans include unlimited sends. Prices verified 2026-10-10: Comfort starts at $12/month, Power at $25/month, free covers 250 subscribers and 2,500 emails/month. Annual billing saves 10%.
• Mailchimp bills by contacts — and contacts include unsubscribed contacts and duplicates unless you archive them. Each plan also carries a monthly send multiplier: Essentials 10× your contact tier, Standard 12×, Premium 15×, free capped at 500 emails/month (max 250/day). Standard starts at $20/month as an intro rate for the first 12 months — then the price rises, so check your renewal rate. Nonprofits get 15% off (MailerLite offers 30%).

That gives you two concrete ways Mailchimp ends up more expensive than its pricing page suggests:

1. Dead contacts inflate your tier. A 5,000-name list with 1,500 unsubscribes bills as 5,000 on Mailchimp (until archived) and 3,500 on MailerLite. At real list hygiene — most small-business lists carry 10–25% dead weight — Mailchimp’s effective per-active-subscriber price is noticeably worse than the table shows.
2. The intro-rate cliff. Mailchimp’s $20/month Standard starting price is a 12-month intro. Budget for the renewal price, not the headline.

Once you see both costs clearly, the comparison becomes straightforward: Mailchimp has to justify roughly a 30–60% premium with features you’ll actually use.

Pricing head-to-head (researched 2026-10-10)

Mailchimp pricing is per-contact-tier and varies by plan. The two plans a small business would compare against MailerLite’s Comfort and Power are Essentials and Standard. (Mailchimp Premium is enterprise territory and excluded.) Note the Standard column below shows the intro rate; renewals run higher.

Comfort and Power tiers from MailerLite’s official pricing page; Mailchimp tiers cross-checked across current third-party pricing breakdowns (they agree to the dollar at every band). Two structural notes:

• Comfort’s send cap: 10× your subscriber tier per month (so the 2,500 tier allows 25,000 sends). Cross it regularly and Power’s unlimited sending ($49 at that tier) is the fix.
• Mailchimp’s send caps: Essentials allows 10× contacts, Standard 12×, Premium 15×. A frequent sender can hit Essentials’ ceiling — check your monthly send volume, not just your list size.

Free plans, side by side. MailerLite free: 250 subscribers, 2,500 emails/month, automation included, website and landing page included. Mailchimp free: 250 contacts, 500 emails/month max (250/day), no automation flows, no scheduling, 1 audience, 1 seat. Both keep vendor branding. If “free” matters to you, MailerLite’s free tier is a real starting plan; Mailchimp’s is a trial wearing a free-plan label.

Two worked examples: your list, your money

Example 1 — newsletter, 2,500 subscribers, 8 emails/month (20,000 sends).

• MailerLite: the 2,500 tier is $33/month on Comfort, with a 25,000-send cap — fits. $33/month.
• Mailchimp: 2,500 contacts is $45/month on Essentials (25,000-send cap — fits) or $60/month on Standard. $45–60/month.

Example 2 — e-commerce store, 10,000 contacts, 6 emails/month (60,000 sends).

• MailerLite: the 10,000 tier is $89/month on Comfort, cap 100,000 sends — fits. $89/month.
• Mailchimp: 10,000 contacts is $110/month on Essentials (cap 100,000 — fits) or $135/month on Standard. $110–135/month.

Example 3 — the dead-contact tax: 5,000-name list, 1,500 unsubscribed (not yet archived).

• MailerLite bills 3,500 active → lands in the 5,000 tier. $49/month.
• Mailchimp bills all 5,000 contacts → $75/month Essentials / $100/month Standard.

That third example is the one most comparisons skip, and it’s the one that actually hits small businesses. Mailchimp’s 5,000 tier costs 53% more than MailerLite’s on sticker — and that 53% is really a tax on contacts who can’t even receive your emails. Archive dead contacts on Mailchimp routinely, or pay MailerLite’s price structure instead.

Features head-to-head

Bold takeaways from that table:

• Mailchimp’s premium buys three things: integrations depth (300+), e-commerce intelligence (predictive segments, purchase likelihood, CLV tracking on Standard+), and multi-channel reach (SMS add-on, social posting). If you use none of them, you’re paying for a brand name.
• MailerLite’s edge is structural, not just cheaper: a website builder, paid newsletters, and digital-product sales come included on every plan. For creators and small businesses selling directly, that’s tooling Mailchimp makes you buy separately or integrate around.
• The approval friction cuts both ways. Mailchimp lets you start sending in minutes. MailerLite’s stricter approval — requiring domain authentication before your first campaign — is annoying on day one and a deliverability feature from day two: it keeps spammers off the shared IPs your emails ride on.
• Ease of use is a real, rated difference. G2 puts MailerLite at 4.7 and Mailchimp at 4.4 across thousands of reviews. For a one-person marketing operation, the tool you’ll actually open beats the tool with more buttons.

Deliverability: the honest answer

Independent seed-list tests in 2026 generally put MailerLite slightly ahead — EmailToolTester’s 2026 averages showed MailerLite around 94% inbox placement versus Mailchimp in the low-to-mid 80s. But treat that as context, not a verdict. At this level, your own setup dominates: whether your domain has SPF, DKIM, and DMARC configured, whether your list is opt-in and regularly cleaned, and whether subscribers actually open your mail. A disciplined list on either platform outperforms a neglected list on either platform. We covered the full mechanism in our email deliverability guide.

The verdict: best for each business type

Pick MailerLite if:

• You want the most email marketing per dollar — 30–50% cheaper at every tier.
• Your list carries dead weight and you don’t want to pay for it (active-subscriber billing).
• You run a newsletter or creator business and want paid subscriptions and digital-product sales built in.
• You want the simplest tool that still does automation properly — and a free plan that’s actually usable.
• Typical fit: creators, coaches, service businesses, small e-commerce stores sending product newsletters.

Pick Mailchimp if:

• You’re deep in e-commerce and will actually use predictive segmentation, purchase-likelihood scoring, and multivariate testing.
• You need 300+ native integrations or live in the Shopify/Intuit ecosystem.
• You want SMS and social posting alongside email in one account.
• Your team is large enough that unlimited users (Standard/Premium) and onboarding specialists matter.
• Typical fit: growing e-commerce stores, multi-channel retailers, businesses already paying for the Intuit stack.

Before you decide, run these three checks: (1) on Mailchimp, archive dead contacts and price the cleaned contact count, not the raw one; (2) on MailerLite, check whether your monthly sends fit inside Comfort’s 10× cap — if not, price Power, not Comfort; (3) on Mailchimp Standard, price the renewal rate, not the 12-month intro.
