You’ve been meaning to start a newsletter for six months, or you’re already sending campaigns through a tool you picked without much research and now the pricing is climbing faster than your list is. Either way, picking the best email marketing software for small business isn’t just a tool decision — it’s a budget decision, because every major platform prices differently, and what looks cheap at 500 subscribers gets expensive fast at 5,000. I’ve set up email marketing for local service businesses, ecommerce brands, solo consultants, and content creators across most major platforms, and the answer depends heavily on what you’re actually trying to do. Here’s the honest breakdown with current July 2026 pricing across every platform worth considering.
Key Takeaways
MailerLite is the best overall email marketing platform for most small businesses. At $9/month for up to 1,000 subscribers (growing business plan), it delivers automation, segmentation, landing pages, and a real email builder for a fraction of what Mailchimp charges at the same list size.
Mailchimp’s free plan was reduced to just 250 contacts in January 2026, making it essentially a demo tier. Any small business actually trying to build a list should start on MailerLite (free up to 1,000 subscribers) or Kit (free up to 10,000 subscribers) before paying for anything.
Brevo is the best pick for businesses with large, infrequently-emailed contact lists. It prices by email sends rather than contacts, so a business with 20,000 contacts that sends one newsletter a month pays far less than it would on any contact-based platform.
Klaviyo is the best pick for Shopify and ecommerce brands that need serious revenue attribution. Its deep store integrations justify higher pricing for product businesses; for service businesses and newsletters, it’s overkill and overpriced.
What to Look for in Email Marketing Software
The right platform for a small business comes down to three questions: how does it price (by contacts, by sends, or flat rate), what level of automation (sequences of emails triggered by subscriber behavior) is available on the entry tier, and how clean is the email builder for the type of campaigns you’ll actually send. Get those three right and the rest is secondary.
Pricing Model: Contact-Based vs Send-Based vs Flat Rate
This is the most important structural decision and the one most small businesses don’t think about until a bill surprises them. Contact-based pricing (Mailchimp, Kit, MailerLite, Klaviyo) charges based on how many subscribers are in your account — costs climb as your list grows, regardless of how often you email. Send-based pricing (Brevo) charges based on how many emails you send per month — a business with a large list that sends infrequently pays dramatically less. Flat-rate pricing (Beehiiv, to some extent) charges a fixed amount up to a subscriber tier, which simplifies budgeting.
Automation Depth on Entry Tiers
Email automation — sequences of emails triggered automatically by subscriber actions like joining a list, clicking a link, or making a purchase — is gated behind paid tiers on most platforms. Mailchimp only unlocks multi-step automations on Standard ($20/month+). MailerLite includes automation on its free plan. Kit’s free tier includes one automation; paid Creator unlocks unlimited visual automations. Know the automation tier you’re actually buying before committing.
Deliverability — The Feature Nobody Talks About
Email deliverability (the percentage of your emails that actually land in the inbox rather than spam) varies by platform and matters enormously for a small business trying to build a real relationship with its list. Established platforms like Mailchimp, Klaviyo, and MailerLite have strong shared infrastructure. Newer or cheaper platforms sometimes cut corners on deliverability infrastructure, which quietly destroys the ROI of every campaign you send regardless of how good the content is.
Best Overall — MailerLite
MailerLite is the best overall email marketing platform for most small businesses at $9/month for the Growing Business plan (up to 1,000 subscribers, billed monthly — $7.50/month annually). It includes an email editor with real template customization, multi-step automation workflows, landing pages, pop-up forms, A/B testing, and email scheduling — features Mailchimp gates behind Standard at $20/month for the same list size.
What You Get and What It Costs
MailerLite’s free plan covers up to 1,000 subscribers and 12,000 email sends per month with automation included — a genuinely useful free tier that Mailchimp no longer matches with its January 2026 cut to 250 contacts. Growing Business pricing scales cleanly: $9/month at 1,000 subscribers, $19/month at 2,500, $32/month at 5,000, $57/month at 10,000. Annual billing drops each by about 17%. The Advanced plan at $18/month (1,000 subscribers) adds unlimited users, an AI writing assistant, and promotional pop-ups — generally overkill for a solo small business operator.
The Honest Downside
MailerLite’s template library is thinner than Mailchimp’s, and the drag-and-drop builder is less polished for complex promotional email layouts. For a product brand sending heavily visual promotional campaigns, the design limitation is noticeable. For a service business or newsletter operator sending text-focused or moderately designed emails, it’s barely relevant. The free plan also doesn’t include custom domain email verification without a paid plan, which means your emails go out from a generic MailerLite address until you upgrade.
Best Free Option — Kit (formerly ConvertKit)
Kit’s free Newsletter plan is the best genuinely free email marketing tier available in 2026, supporting up to 10,000 subscribers with unlimited email sends, unlimited landing pages, and basic forms at no cost. That’s 40x more contacts than Mailchimp’s free plan (250 contacts as of January 2026) and 10x more than MailerLite’s free tier.
Who the Free Tier Is Actually For
Kit’s free plan makes the most sense for a content creator, blogger, consultant, or solo business owner building a newsletter list from zero who wants real runway before paying anything. The limitation is a single automation sequence — you can build one welcome email flow, but not multiple simultaneous behavior-triggered workflows. For a business that needs multi-step automation from day one, MailerLite’s free plan (which includes full automation) is the stronger zero-cost starting point.
Paid Kit Plans
Kit’s Creator plan starts at $39/month for up to 1,000 subscribers (monthly) or $33/month on annual billing, scaling to $59/month at 3,000 subscribers, $89/month at 5,000, and $139/month at 10,000. Kit raised prices approximately 35% in September 2025, which makes it noticeably more expensive than MailerLite at every comparable list size — the premium is justified if you use Kit’s digital product sales, paid newsletter subscriptions, and creator referral network. If you just need email automation, MailerLite is cheaper for the same functionality.
Best for Ecommerce and Shopify Stores — Klaviyo
Klaviyo is the best email marketing platform for Shopify, WooCommerce, and other ecommerce businesses that need email revenue attribution — tracking exactly which emails drove which purchases — and deep product-data integration at the campaign level. Its free plan covers 250 contacts and 500 emails per month; paid plans start at $45/month for 1,001-1,500 contacts (Email only) or $60/month for 1,501-2,500 contacts.
What Makes Klaviyo Worth Its Price for Product Businesses
Klaviyo’s real strength is that it syncs your store data directly into email logic. You can send an email specifically to people who bought a specific product, viewed a product page without buying, or haven’t purchased in 90 days — and every campaign reports the exact revenue generated per email sent. For a business doing $20,000+/month in ecommerce revenue, that attribution data pays for the platform in the first optimization cycle.
Where Klaviyo Falls Short
For a service business, consultant, or newsletter operator, Klaviyo is overbuilt and overpriced. Its pricing is aggressive for small contact lists, its interface is optimized for ecommerce workflows, and its learning curve is steeper than MailerLite or Mailchimp for a non-ecommerce use case. A service business paying $45-60/month for Klaviyo when MailerLite handles the same email workflow at $9-19/month is wasting money on features that never get used.
Best for Large Lists — Brevo
Brevo (formerly Sendinblue) is the best email marketing platform for businesses with large contact lists that send infrequently — a business with 20,000 contacts sending one newsletter a month pays dramatically less on Brevo’s send-based pricing than on any contact-based competitor. Its Starter plan at $25/month covers 20,000 email sends; Business at $65/month covers 20,000 sends with full automation and A/B testing.
Why Brevo’s Pricing Model Changes the Math
On Mailchimp Standard, a business with 20,000 contacts pays roughly $270/month. On Kit Creator, the same contact count costs around $200/month. On Brevo, a business sending 20,000 emails to 20,000 contacts once a month pays $25/month on Starter. The difference is that Brevo charges for sending rather than storing — once your list grows large but your sending frequency stays low, Brevo’s economics are dramatically better than contact-based competitors.
The catch: if you’re emailing your full list multiple times a week, Brevo’s send costs scale accordingly and the advantage narrows. At high send frequency, contact-based pricing often becomes cheaper.
Pricing Comparison — What You’ll Actually Pay in July 2026
Here’s a clean comparison across all five platforms at common list sizes, monthly billing.
Monthly Cost by Subscriber Count
| Platform | 1,000 contacts | 2,500 contacts | 5,000 contacts | 10,000 contacts | Pricing Model |
| MailerLite | $9/mo | $19/mo | $32/mo | $57/mo | Per contact |
| Mailchimp Essentials | $17/mo | $45/mo | $75/mo | ~$110/mo | Per contact |
| Mailchimp Standard | $26/mo | $60/mo | $100/mo | ~$135/mo | Per contact |
| Kit Creator | $39/mo | $59/mo | $89/mo | $139/mo | Per subscriber |
| Klaviyo Email | $45/mo | $60/mo | $100/mo | $175/mo | Per contact |
| Brevo Starter | $25/mo (20K sends) | $25/mo | $25/mo | $25/mo | Per send |
| Beehiiv Scale | $42/mo (annual) | $42/mo | $84/mo | $84/mo | Flat per tier |
What This Actually Means for a Real Small Business
MailerLite is the cheapest contact-based platform at every list size. Brevo is cheaper than all contact-based platforms once your list exceeds a few thousand and your send frequency is low. Kit is the most expensive per subscriber among general-purpose tools but bundles digital product sales and a creator monetization layer that justify the cost for the right user.
How to Choose the Right One for Your Business
The decision tree is simpler than most comparison articles make it look.
Decision Guide by Business Type
Service business or consultant with a small list (under 2,500): Start on MailerLite’s free plan. Upgrade to Growing Business at $9/month when you need more design control or want to remove the MailerLite branding from your emails.
Content creator or newsletter operator: Start on Kit’s free Newsletter plan (up to 10,000 subscribers, unlimited sends). Upgrade to Kit Creator at $33/month annual when you need unlimited automations and integrations.
Ecommerce or Shopify store: Start on Klaviyo’s free plan to test the store integration, then budget $45-60/month as your list crosses 1,000 contacts. The ecommerce attribution data justifies the premium for any store doing meaningful volume.
Business with a large list and low send frequency: Brevo’s Starter at $25/month for 20,000 sends is dramatically cheaper than contact-based competitors for this profile.
Business that needs email + CRM in one login: HubSpot’s Marketing Starter at $20/user/month bundles email marketing into the same platform as the CRM, contact management, and basic sales pipeline — worth evaluating before paying for email marketing separately when your CRM is already HubSpot.
A Clear Stance on Mailchimp
A clear stance worth stating directly: Mailchimp’s January 2026 free plan cut to 250 contacts has effectively removed it from the “best starting option” conversation for small businesses building a list. Its paid tiers are the most expensive among the tools compared here at equivalent list sizes, and multi-step automation is only available on Standard ($20+/month). The only case where Mailchimp clearly wins is a product-based business needing its ecommerce integrations at smaller list sizes — and even then, Klaviyo is a stronger purpose-built option for that use case. For the majority of small businesses, starting on MailerLite and migrating to a specialized tool later is the better default path.

MailerLite is the best overall email marketing platform for most small businesses in 2026 — it costs $9/month at 1,000 subscribers, includes full automation, and delivers more features per dollar than Mailchimp at every list size.
What is the best free email marketing tool for a small business?
MailerLite’s free plan (1,000 subscribers, 12,000 emails/month, automation included) and Kit’s free Newsletter plan (10,000 subscribers, unlimited sends, one automation) are the two strongest free options — MailerLite for businesses needing automation from day one, Kit for content creators building a list without an initial budget.
How does MailerLite compare to Mailchimp for small business?
MailerLite is significantly cheaper than Mailchimp at every comparable list size and includes multi-step automation on both its free and paid plans, while Mailchimp locks automation behind its Standard plan starting at $20/month — making MailerLite the stronger value for most small businesses.
What email marketing platform works best for Shopify?
Klaviyo is the strongest email marketing platform for Shopify stores because it syncs product data directly into email logic, enabling abandoned cart flows, post-purchase sequences, and win-back campaigns with revenue attribution data that shows exactly which emails generated sales.
Is Brevo cheaper than Mailchimp for large email lists?
Yes — Brevo’s send-based pricing at $25/month for 20,000 sends per month is dramatically cheaper than Mailchimp’s $270/month for 20,000 contacts on Standard, making Brevo the better choice for businesses with large lists that send infrequently.
What is the best email marketing platform for a newsletter business?
Kit’s free Newsletter plan (up to 10,000 subscribers) and Beehiiv’s Scale plan ($42/month annual) are both built specifically for newsletter operators, with Kit including digital product sales and Beehiiv including built-in ad monetization for newsletters with a larger audience.
Do small businesses need email marketing software or can they use Gmail?
Gmail’s sending infrastructure isn’t built for bulk email — it has daily send limits, lacks automation, and using it for mass outreach risks your business email domain being flagged for spam. Any business sending the same email to more than 100 people simultaneously should use a dedicated email marketing platform with proper deliverability infrastructure.
Conclusion
If you want the direct answer: start on MailerLite’s free plan, which gives you 1,000 subscribers and full automation at no cost, and upgrade to Growing Business at $9/month when your list outgrows it. Switch to Kit if you’re a creator building a newsletter and content monetization strategy — its free tier covers 10,000 subscribers, making it the most generous zero-cost starting point in the category. Move to Klaviyo only when your business is ecommerce-focused and you need real revenue attribution data tied to your email campaigns. Mailchimp is not the default recommendation it used to be at any list size given its 2026 pricing trajectory.
