10 Best Email Marketing Software of 2026

MailerLite gives the most email marketing per dollar on this list without feeling like a budget product. The free plan already includes automations, a landing page, signup forms and a digital product or booking page for up to 250 subscribers and 2,500 emails a month. Comfort, at $10.80 per month billed yearly for 500 subscribers, raises the limits to 50 automations, 10 forms, 10 sites, 3 user seats and 5,000 monthly emails, and removes the MailerLite logo. Power at $22.50 removes the send cap and the automation, form and seat limits, and adds live chat support, which matters for teams that send daily. The trade-off is depth. There is no built-in CRM, segmentation and reporting are simpler than ActiveCampaign or Klaviyo, and very large lists move to custom Enterprise pricing above 200,000 subscribers. For a business that sends a newsletter, runs a welcome series and sells a few products, those limits rarely bite.

Brevo prices its plans by how many emails you send each month rather than how many contacts you store, which changes the math for businesses with big lists and modest sending. The free plan lets you send up to 300 emails a day once your account is approved. Starter adds sending from 5,000 emails a month, advanced segmentation, forms, an AI content generator and email support, while Standard is where marketing automation arrives, with unlimited multi-step workflows, A/B testing, send time optimization, web and event tracking and one landing page. Professional, from 150,000 emails a month, adds WhatsApp, popups, push notifications, ten seats, contact scoring and phone support. Brevo also sells transactional email and SMS through its API and SMTP relay, so product emails and campaigns can share one sender. The weak spot for a newsletter-only buyer is that automation sits a tier up, and we could not confirm USD prices from our location.

Kit is built around the creator who writes a newsletter and sells to it, and its pricing page reflects that. The free plan covers up to 10,000 subscribers with unlimited landing pages, forms and broadcasts, plus tagging, segmentation and selling of digital products and subscriptions, which is far more room than the 250 or 500 contacts most free tiers allow. Creator, at $33 per month billed yearly for 1,000 subscribers, adds unlimited visual automations and sequences, polls, SMS, RSS campaigns, removes Kit branding and opens apps and integrations. Pro at $66, discounted in the first year at the time of our check, adds unlimited users, engagement scoring, deliverability reporting, collaborative editing and a newsletter referral system. Business buyers should know the tool leans toward audience growth and paid content rather than retail promotions, and that paid automation costs more here than at MailerLite for the same list size.

ActiveCampaign has the deepest automation on this list, and unlike several rivals it puts multi-step automation on its cheapest plan. Starter costs $15 per month billed yearly for 1,000 contacts and includes 10,000 monthly sends, AI-powered automation and campaign builders, more than 250 templates and 15 active business goals, but only one user and limited segmentation. Plus at $49 adds cross-channel marketing, landing pages, site messages, generative AI for content and images, standard segmentation and an optional enhanced CRM. Pro at $79 brings predictive sending at each contact's best time, conditional content, advanced segmentation, attribution and three seats. Enterprise from $145 adds single sign-on, HIPAA support, custom objects and a dedicated account team. The builder offers a lot of control, which also means a steeper learning curve than MailerLite or Constant Contact, and costs climb quickly as the contact count rises.

Mailchimp remains the reference point for small business email, and its plan structure is easy to read. The free plan covers audiences under 250 contacts. Essentials adds testing and scheduling, three seats, three audiences and 5,000 monthly sends, but its automation stops at four flow steps. Standard is the plan most businesses need: up to 200 flows, branded templates, custom reports, dynamic content, five seats and an onboarding session. Premium adds unlimited seats and audiences, 150,000 monthly sends, phone support and enterprise single sign-on. Every paid plan includes popup forms, pre-built templates, removal of Mailchimp branding and more than 300 integrations, and nonprofits can request a 15% discount. The main drawbacks are cost as a list grows, overage charges when you pass contact or send limits, and the gap between Essentials and Standard automation. We could not confirm USD prices from our location.

Klaviyo is the specialist for ecommerce email, and its strength is data rather than design. The platform builds a unified profile for each shopper from store activity, which feeds segments, flows and campaigns, so abandoned cart, post-purchase and win-back messages can react to what a customer did. The free plan lets you import or sync contacts, use drag-and-drop editors and build automations, segments and reports for up to 250 active profiles and 500 email sends a month, with $5 of mobile messages and $5 of Composer usage. Beyond email, Klaviyo covers SMS, RCS, WhatsApp and mobile app messaging, plus a service suite with a helpdesk and an AI Customer Agent, and it connects to more than 400 apps. The trade-offs are cost and focus. Paid prices are set by a profile calculator we could not confirm in USD, and a service business sending a monthly newsletter will pay for ecommerce depth it never uses.

Constant Contact sells support and simplicity as much as software. Every plan includes live one-to-one onboarding and live phone and chat help, which is rare at the low end, and Lite starts at $10.20 per month billed annually, the lowest verified entry price on this list. Lite covers the drag-and-drop editor, an AI copy generator, scheduled social posts, basic reporting, web signup forms, one custom segment, one automation template and event hosting with payments. Standard from $29.75 adds subject line testing, open and click reporting by contact, three automation templates, an AI campaign builder and automatic resends to non-openers. Premium from $68 adds dynamic content, custom and ecommerce automations, unlimited segments, ad tools and 500 SMS messages. Monthly sends are capped at 10, 12 or 24 times your contacts, and overages are billed at $0.002 per email rather than blocked. Automation depth is the weak point until Premium.

GetResponse removes one variable from email budgeting: every plan includes unlimited monthly sends, and price follows list size. Its pricing FAQ puts monthly plans from $19 for 1,000 subscribers, with 18% off a 12-month term. Starter covers AI content generators, a welcome email series, one custom automation workflow, the landing page builder, signup forms, popups and SMS. Marketer is the real marketing plan, adding unlimited workflows, advanced segmentation, abandoned cart recovery, sales funnels, promo codes and web push. Creator adds webinars, a website builder, a course creator for up to 500 students and premium newsletter subscriptions, which suits coaches and educators. Enterprise brings a dedicated IP, transactional emails and single sign-on. The catch is that Starter's single workflow is thin for anyone who wants automation, so most buyers should price Marketer, and the plan cards showed local currency from our location.

AWeber is a straightforward email tool that has added selling and setup services. Lite costs $12.49 per month billed annually and includes 24/7 support, advanced message analytics, landing page features, sales tracking and branding removal, but it limits you to one list, three landing pages, three automations, three users and one custom segment, with a 1.0% transaction fee on sales. Plus at $19.99 billed annually removes those limits, giving unlimited lists, landing pages, automations, segments and users, priority support, advanced reporting and a lower 0.6% fee. The Done For You plan adds a seven-day expert build of templates, landing pages, a signup form and a welcome series. AWeber's feature list also includes RSS to email, AMP emails, split testing, behavioral automation and web push notifications. The main limits are a smaller automation toolset than ActiveCampaign or Klaviyo, and monthly billing that costs noticeably more than the annual figure.

Campaign Monitor is a design-led email tool that suits teams sharing templates. Every plan includes unlimited users, and the core toolkit covers a drag-and-drop builder, a customizable template library, segmentation tools, A/B testing and real-time reporting. Lite, listed at $11.70 per month with the annual discount for up to 500 contacts, adds custom coded templates, drip campaigns, unlimited signup forms, an AI writer, pre-built journeys and transactional emails, but caps sends at five times your subscriber count each month. Essentials moves to unlimited sends, priority support, inbox preview, unlimited AI email features and Marketing Studio for generating on-brand emails and images. Premier adds phone support, engagement segments, send time optimization, email section locking, template management for teams and the website builder that other plans buy at $10 a month. The trial runs 30 days with 500 contacts. Automation is solid for drips but lighter than ActiveCampaign, and costs rise steadily with list size.
