The best email marketing software depends on the business you are building.

MailerLite is the most broadly useful platform in this five-tool shortlist. It combines newsletters, automations, signup forms, landing pages, websites and digital-product tools in one relatively approachable interface. That breadth matters for a small business because the platform can cover list growth and everyday campaign work without forcing the team into a highly specialized creator, publisher or ecommerce operating model.

The current plan structure is straightforward at entry level. The Free plan supports up to 250 subscribers and 2,500 monthly emails. Comfort begins at $12 per month and uses a monthly sending allowance tied to the subscriber tier, while Power begins at $25 and adds unlimited monthly emails, unlimited seats and broader feature usage. The exact price rises with subscriber count, so the entry price should not be used as a long-term budget for a growing list.

MailerLite is not the winner when a business needs deep CRM logic, predictive ecommerce data or a native advertising marketplace. Its automation is useful rather than enterprise-grade. That is the trade-off behind its recommendation: it removes friction for ordinary email marketing instead of maximizing complexity.

Kit is designed around creator economics rather than conventional small-business marketing. Tags, sequences, visual automations, landing pages, recommendations and commerce tools are organized around building a direct audience and moving subscribers toward a creator's products, memberships or paid content.

Its free Newsletter plan is unusually large at up to 10,000 active subscribers with unlimited broadcasts, but the headline limit needs context. The plan includes only one basic Visual Automation and one email sequence, and participation in the Creator Network includes a Kit-controlled Smart Recommendation position. That can still be excellent for a growing creator, but it is not the same as receiving the full paid workflow at no cost.

The Creator plan starts at $39 per month for up to 1,000 subscribers, with two months free on annual billing. Pro starts at $79 and adds more advanced reporting, audience and growth capabilities. Kit becomes less compelling when a company primarily wants polished general-purpose campaigns, store-native lifecycle data or a publishing website built around advertising.

beehiiv combines email delivery with a public newsletter website, referral mechanics, recommendation tools, paid subscriptions, digital products and an advertising network. That integrated publishing model makes it materially different from a normal email service provider. A team can operate a publication, grow it and monetize it without stitching together as many separate systems.

The Launch plan supports up to 2,500 subscribers and unlimited sends at no monthly cost. Scale begins at $49 per month, or an effective $43 per month when billed annually at the current entry tier, and adds the features that make beehiiv commercially distinctive: automations, the Ad Network, paid recommendations and digital products. Max starts at $109 monthly and expands team, publication and branding capabilities.

The most important limitation is fit. beehiiv is not a substitute for a deep ecommerce lifecycle platform, and its Ad Network should never be treated as guaranteed income. Publishers still need an audience that advertisers want and suitable marketplace opportunities. For a normal service business, many of beehiiv's strongest features are irrelevant.

Omnisend packages email, web push and—on the appropriate current plan—SMS around ecommerce use cases. Its prebuilt workflows, product-aware editor, segmentation and store integrations make abandoned-cart, welcome, product follow-up and reactivation campaigns faster to deploy than a general-purpose platform.

Standard starts at $16 per month and includes most of the email marketing feature set with a sending allowance based on the contact tier. Pro begins at $59 and offers unlimited email at the selected contact level, while SMS is now structured separately for new customers and requires the current Pro plan plus SMS credits. The Free plan can send 500 emails per month and is useful for evaluating the workflow rather than running a mature store program.

The critical budgeting detail is the definition of billable contacts. Omnisend can count both subscribers and certain non-subscribers, including customers or contacts created through ecommerce behavior. A store should inspect its billable audience inside the account instead of estimating cost only from its marketing-consent list.

Klaviyo is the most data-intensive platform in this shortlist. It can combine purchase history, browsing events, profile properties, integration data and predictive signals in dynamic segments that update as customer behavior changes. Those segments can trigger flows, personalize campaigns, sync audiences and support detailed lifecycle strategies.

The free tier supports up to 250 active profiles, 500 monthly email sends and $5 of mobile messaging. Paid email pricing is tied to active profiles and sending capacity rather than a simple newsletter-subscriber number. Klaviyo defines an active profile as a profile that can be emailed through the platform; that can include a checkout customer who did not join a conventional newsletter list. Suppressed profiles do not count toward the email plan.

This depth is valuable only when the organization can use it. A small store that needs a welcome flow and abandoned-cart messages may gain more from Omnisend's faster setup. A brand with a retention team, meaningful order volume and a mature data model can use Klaviyo's complexity as an advantage rather than an administrative burden.
