AI has completely changed email marketing. In 2026, the best tools do far more than send and host messages. They help you write copy, select the right audience, choose the optimal send time, and adjust in real time to subscriber behavior. Modern platforms generate subject lines, personalize every message, and continually improve results. If you are still sending the same message to your entire list, you are likely falling behind.

What is the best email marketing software right now?

After hands-on testing of real email campaigns, Mailchimp is the best overall email marketing platform. It is easy to use, reliable, and full of useful features without becoming cluttered. HubSpot is the strongest option for businesses that need deep CRM integration and automation. MailerLite is the best budget-friendly choice for creators and small teams, while Brevo excels at multichannel campaigns. Klaviyo is the default pick for e-commerce stores because it is built around online sales and customer retention.

Best email marketing software in 2026

Mailchimp: Best email marketing software overall

Mailchimp remains the easiest way for new marketers to launch professional email campaigns. Its free plan lets you sign up instantly and build your first campaign. The dashboard presents step-by-step buttons help you import contacts, connect integrations, and set up your brand persona. You can use a template or create a design from scratch. The drag-and-drop editor simplifies the process, but the free templates are fairly basic. The automation builder triggers emails based on signups, tags, events, or custom criteria. Both prebuilt and custom journeys are flexible, although moving from classic automations to the newer system requires rebuilding flows and upgrading. Mailchimp also recommends common flows like onboarding, Meta lead follow-up, and birthday campaigns. You can preview them on the free plan, but you must pay to launch them. Once you understand how triggers and actions work, you can create surprisingly complex sequences.

Mailchimp pricing begins with a free plan for 500 contacts. Paid plans are Essentials at $13 per month, Standard at $20 per month, and Premium from $350 per month for 10,000 or more contacts. There is also a Pay As You Go option. Paid plans have a 14-day free trial, and nonprofits receive a 15% discount. Key features include email and SMS campaign builders, prebuilt automation flows, segmentation, signup forms, a landing page builder, and more than 250 integrations. The interface is clean and reports are insightful, but free-plan analytics are not included and pricing rises quickly as your list grows.

HubSpot: Best email marketing software with CRM automation

HubSpot is best for marketers who want email to work alongside CRM data, sales outreach, and long-term customer journeys. Its biggest advantage is that everything is already connected. Creating an email begins with three options: regular, automated, or blog-triggered. The editor is clean and clearly laid out. For advanced automation, HubSpot offers visual workflows with branching logic, lead scoring, and goal tracking. A campaign can start from a form fill, email click, or blog visit. HubSpot automatically decides which content goes to each segment, who receives a follow-up, and when to pause a sequence. In testing, this felt like managing a complete system rather than simply drafting emails.

The reporting tools are significantly deeper than most competitors. The Analyze and Health tabs provide real-time deliverability benchmarks. Custom dashboards can pull metrics from email, sales, and web behavior into one place. The built-in AI Copilot appears on the right side of the editor, making it possible to summarize contact information, research companies, or rewrite subject lines by tone. The free plan includes 2,000 sends per month, which is enough for many small lists. Paid plans start with Marketing Hub Starter at $9 per month. Marketing Hub Professional costs $800 per month for 2,000 contacts and includes a $3,000 onboarding fee. Marketing Hub Enterprise costs $3,600 per month for 10,000 contacts, with onboarding starting at $7,000. Delivering strong automation and analytics, but the interface feels overwhelming and the upper tiers are costly.

MailerLite: Best email marketing software for creators and small teams

MailerLite is an all-around marketing tool for creators and small teams. It supports email campaigns, behavior-based automation, forms, landing pages, and subscriber management. The drag-and-drop campaign editor offers regular, A/B, auto-resend, and RSS campaigns. A subject-line preview pane, personalization tokens, and sender settings are presented before design work begins. You can see live previews while editing, and available content blocks include countdowns, image galleries, and coupon codes. Any campaign can be saved as a custom template. Forms and landing pages use the same visual interface, so there is no need to learn a separate builder. This is especially useful for setting up double opt-in flows and seeing exactly what users experience.

MailerLite’s automation builder is simple and capable. You choose a trigger, such as a subscriber joining a group or clicking a link, then add delays, emails, and conditions. In testing, a three-email onboarding flow with one condition was created in less than 10 minutes. Analytics on paid plans include open rates, click-through rates, unsubscribes, and heatmaps. MailerLite integrates with more than 140 tools and offers inexpensive A/B testing. It does not work with Gmail accounts and its free plan lacks automation templates, but overall it is approachable yet flexible. Plans start free for up to 1,000 subscribers and 12,000 monthly emails. Growing Business costs $10 per month, and Advanced costs $20 per month. New users get a 30-day trial of premium features.

Brevo: Best email marketing software for multichannel campaigns

Brevo combines marketing and transactional email in a single dashboard. You can name a campaign, choose recipients from a list, and customize the subject line. Personalization tokens are available directly in the subject field. Brevo can pull branding from a website URL, automatically importing a logo, colors, and fonts. The email editor provides full control over content blocks, sections, and brand styles. Its AI assistant is useful for generating paragraph text, shortening copy, or adjusting tone. Mobile previews update without requiring a full reload. Saved templates and custom content sections can be reused across campaigns, while scheduling options support sending now, later, or at the best time based on engagement.

Brevo’s analytics show opens, clicks, bounces, unsubscribes, and heatmaps. It is not as deep as HubSpot’s CRM reporting, but it is easy to access and act on for basic and mid-tier needs. The free plan caps sends at 300 emails per day. The Starter plan begins at $9 per month and raises the cap to 5,000 emails per month, adds 24/7 support, and includes analytics. Removing Brevo’s logo is an add-on. The Business plan starts at $18 per month and unlocks workflows, predictive sending, landing pages, multi-user access, A/B testing, advanced stats, and phone support. With 150+ integrations and 50+ email templates, Brevo is beginner-friendly. The limitations include daily email caps on free and custom branding placed behind paid tiers.

Klaviyo: Best email marketing software for e-commerce automations

Klaviyo is designed for e-commerce, especially stores using Shopify. It covers segmentation, automation, and campaign targeting with online sales in mind. Klaviyo automatically sets up branding, domain authentication, and store sync. Its Flows section contains prebuilt templates for welcome emails, cart abandonment, post-purchase follow-up, browse abandonment, win-back, and review requests. The abandoned checkout flow triggers when shoppers begin the checkout process and inserts product details dynamically. A reminder and urgency-based call-to-action can form a high-performing series in under an hour. Campaigns can target engaged segments based on recent open and click activity. Klaviyo tracks opens, clicks, conversions, and revenue synced from Shopify or WooCommerce.

Signup forms are highly customizable. You can build a two-step popup with email and SMS fields, target it by device, and delay the trigger. During testing, a popup offering 10% off increased opt-ins when it forced users to click a “No thanks, I’ll pay full price” link. Klaviyo’s free tier supports 500 emails to 250 profiles. The Email plan starts at $20 per month for 500 profiles and adds reporting dashboards, AI content generation, logo removal, and ongoing support. For predictive analytics and multichannel features, the Email + SMS plan begins at $35 per month. Klaviyo is not beginner-friendly and is expensive, but its behavioral segmentation, split testing, and AI testing tools make it a powerful fit for direct-to-consumer brands.

Other email marketing software

Constant Contact is a strong alternative for small businesses. It has an intuitive interface and a wide range of third-party integrations. Zoho Campaigns is another good option if you want email marketing alongside social media, CRM, and a website builder from a single provider.

Choosing the right email marketing software

Start by considering how you plan to use email. If you send a monthly newsletter to a few hundred people, Mailchimp is easier and more reliable. If you manage multiple automated flows and need CRM-level control, HubSpot is the better fit. MailerLite suits creators who want a budget tool that does not feel overwhelming. Brevo is the right choice when you need SMS, WhatsApp, or transactional email in the same place. Klaviyo is the strongest option for an e-commerce store that needs revenue-driven flows synced directly with product data.

What to look for in email marketing software

Look closely at how a platform handles contact growth. Many tools are affordable under 500 contacts but become expensive as your list reaches 2,000 or 10,000. Deliverability and list hygiene are important too: good platforms will help you stay out of spam folders, remove inactive subscribers, and track real opens. HubSpot and Brevo offer strong analytics and suppression tools. AI writing features are common, but quality varies. Brevo and Klaviyo provide useful suggestions without being overwhelming. Ease of use matters. In testing, the fastest path from signup to first email was critical, and MailerLite did this better than most.

How we tested email marketing software
