Best Email Marketing Software (2026): Top 10 Compared

Mailchimp sells four Marketing plans: Free, Essentials, Standard and Premium. Its help documentation explains that a plan type and a pricing tier together set the monthly bill, and that the tier sets both the contact limit and the sending limit. If the contact total rises above the limit during a billing cycle, Mailchimp adds a charge rather than stopping service.

Essentials includes three audiences, three seats, automation flows of up to four steps, A/B testing and 24/7 email and chat support, and stores up to 50,000 contacts. Standard raises this to five audiences and five seats, adds flow templates, pre-built and advanced segments, custom-coded templates, multivariate testing and custom reports, and stores up to 100,000 contacts. Premium adds unlimited audiences and seats, phone support and screen-share support, and starts at 10,000 contacts.

A Pay As You Go plan, with Essentials features, lets infrequent senders buy email credits instead of a monthly subscription.

Klaviyo describes itself as a B2C CRM. Its platform groups Klaviyo Marketing, Klaviyo Service, Klaviyo Analytics and the Klaviyo Data Platform, and its marketing channels include email, SMS, RCS, mobile app, WhatsApp and social messaging. The product navigation lists segmentation, personalisation, templates, reviews and a helpdesk, plus Composer, which creates and audits flows and campaigns from a prompt, and a Customer Agent for AI-assisted support.

The company's resources are aimed at ecommerce and retail, with seasonal toolkits for Black Friday and Cyber Monday and a global ecommerce playbook, alongside pages for gyms and restaurants. Its app marketplace lists more than 350 integrations, and developers can build on Klaviyo's APIs.

The free plan can be used indefinitely while an account stays at or under 250 active profiles and 500 monthly email sends. Above that, Klaviyo's estimator calculates a price from the chosen products and profile count. Klaviyo defines active profiles as contacts who may receive marketing emails.

Brevo states it has more than 600,000 customers. Its pricing differs from most tools here because plans are sized by monthly email volume rather than by stored contacts.

Starter includes the drag-and-drop editor, templates, an AI content generator, advanced segmentation, forms, basic reporting and email support in six languages. Standard adds unlimited multi-step automation workflows, A/B testing, advanced reporting with click heatmaps, send-time optimisation, web and event tracking, one landing page and removal of the Brevo footer. Professional adds WhatsApp, popups, web and mobile push, 10 seats, contact scoring, AI segmentation, phone support and three hours a year of deliverability specialist support. Enterprise, for companies with more than a million contacts, adds multi-account management, custom objects, a dedicated IP, SSO and a loyalty engine.

Brevo's FAQ states that all plans include transactional email features, including APIs, SMTP and outbound webhooks, which lets one account handle receipts and password resets as well as campaigns.

ActiveCampaign sells email marketing and marketing automation in four plans. All include Active Intelligence, its AI feature set, with limits on the lower plans. The pricing page states a 30-day money-back guarantee.

Starter covers email marketing with limited segmentation and up to five actions per automation, plus standard CRM and ecommerce integrations. Plus adds unlimited automation actions, standard segmentation and landing pages. Pro adds advanced segmentation, premium ecommerce integrations, predictive and conditional content, and attribution and conversion tracking. Enterprise adds premium segmentation, custom objects, single sign-on and a dedicated account team.

Separate WhatsApp plans and a combined email and WhatsApp option are available for teams that message customers on both channels. Because prices scale with contacts, the starting figures apply only to the lowest tier, and buyers should run the calculator at their real list size. ActiveCampaign suits buyers for whom automation logic matters more than template design or free-plan limits.

Constant Contact targets small businesses and nonprofits. Every plan includes live onboarding, live phone and chat support, the drag-and-drop editor, an AI copy generator, social posting to Facebook, Instagram and LinkedIn, event hosting and payments, and more than 300 integrations, including Shopify, Canva and Eventbrite.

The plans differ mainly in automation and segmentation. Lite includes one automation template and one custom segment with basic reporting. Standard adds email scheduling, subject-line testing, three automation templates, an AI campaign builder, automatic resend to non-openers, 10 custom segments and reports showing who opened and clicked. Premium adds dynamic content, unlimited and custom automations, ecommerce templates, unlimited segments, lookalike targeting, Google ad management, SEO recommendations and a dedicated priority support team.

A Multi-Account product serves organisations with five or more accounts, with central sending, approval workflows and shared templates. A free trial is available without a credit card.

MailerLite sells four plans: Free, Comfort, Power and Enterprise. Its pricing FAQ states that pricing is based on usage, not feature access, so customers pay for subscribers and sending volume while the main tools are included on every paid plan.

The Free plan includes up to 250 subscribers, two user seats and 2,500 monthly emails, with campaigns, automations, a website, a landing page, signup forms and all three editors: drag-and-drop, custom HTML and a simple text editor. Comfort adds unlimited templates, dynamic emails, campaign auto-resend, multivariate testing, an unsubscribe page builder, a preference centre, an AI writing assistant and smart sending. Power, aimed at marketers with several revenue streams, adds unlimited seats, monthly emails, automations, forms, digital products and bookings, plus multiple automation triggers.

Enterprise includes a success manager, account audits and deliverability support, with a dedicated IP as an add-on.

Kit states that more than 550,000 creator businesses use it. Its plans are built around audience growth and selling to subscribers.

The Free plan, for up to 10,000 subscribers, includes unlimited landing pages, forms and email broadcasts, tagging and segmentation, and sales of digital products and subscriptions. Creator adds unlimited visual automations and email sequences, subject-line A/B tests, polls, removal of Kit branding, SMS marketing, RSS campaigns, app integrations, the Kit MCP connector and 24/7 email and chat support.

Omnisend is an email and SMS platform for ecommerce. Its pricing page lists more than 305 pre-built integrations and open APIs, and its own marketing compares its cost with Klaviyo's.

All plans, including Free, include 24/7 live chat and email support, free migration and an Omnisend MCP connector for querying the account from an AI tool. Standard, aimed at growing businesses focused on email, adds removal of Omnisend branding, advanced reporting across email and SMS, Forms AI and Reports AI, with personalised content and personalised send time as add-ons from $5 a month.

Marketer, positioned for marketers and ecommerce businesses selling across channels, adds unlimited automation workflows. Creator adds tools for monetising knowledge, including an AI course creator for up to 500 students, premium newsletter subscriptions, a website builder and a free custom domain on yearly plans. Enterprise offers tailored solutions and premium support at a custom price.

A 14-day free trial gives access to premium features without a credit card. Support is available 24/7 in English, Polish, German, Spanish, Portuguese, French and Italian, and Enterprise prospects can join a 30-day pilot programme.

Payment is automatic and in advance, and annual subscribers pay the full year upfront.

AWeber publishes its full pricing table by subscriber count on its pricing page, which few vendors in this comparison do.

Lite includes one email list, three landing pages, three automations, three users, one custom segment, 24/7 support, advanced message analytics and sales tracking, with a 1.0% transaction fee on AWeber Ecommerce sales. Plus removes those limits, offering unlimited lists, landing pages, automations, custom segments and users, priority support, advanced audience analytics, webpage tracking and a 0.6% transaction fee. Both remove AWeber branding and include RSS-to-email, AMP emails, split testing, behavioural automation and web push notifications.
