AI has completely changed the way email marketing works. The best tools in 2026 don't just send or host emails anymore. They help you write them, pick the right audience, choose when to send, and even tweak things in real time based on how people react. They'll come up with subject lines, personalize each message, and keep improving as they go. Honestly, if you're still just sending the same email to everyone, you're already falling behind.

What is the best email marketing software right now?

Right now, Mailchimp is the best overall pick for most people and teams. It is simple, reliable, and has enough features without feeling cluttered. Advanced users who want a complete customer relationship management platform alongside their email marketing should consider HubSpot, especially if they already use HubSpot for sales or service. Creators and small teams should look at MailerLite for a friendly, budget-friendly option, while e-commerce stores on Shopify should investigate Klaviyo for automations built around product data and revenue. Brevo is a strong option for marketers who need multi-channel campaigns combining email, SMS, and WhatsApp.

Mailchimp: Best email marketing software overall

Bottom line

If you're new to email marketing and want a powerful platform that's easy to begin with, Mailchimp should be at the top of your priority list. You can sign up for its free plan and build your first campaign in minutes. Step-by-step buttons guide you through importing or creating contact lists, connecting integrations, and importing your brand persona. Your first round of emails or SMS campaigns can be ready in no time.

Pros and cons

• Clean interface
• Insightful campaign reports
• Strong deliverability for large audience segments
• Visual journey builder
• No analytics on the free plan
• Costs rise quickly as contacts grow

Expert take

You can start from scratch or use a campaign template. The drag-and-drop editor makes the process easy, but the free templates are basic unless you upgrade. The automation builder can trigger emails based on sign-ups, tags, events, or custom criteria. Prebuilt and custom journeys take a few minutes to learn, but they are flexible and powerful. Classic Automations were discontinued in mid-2025, so if you're returning to the platform after a long gap, expect to rebuild workflows and pay for features that once were free.

Mailchimp also surfaces a dashboard of recommended flows built around common goals, like welcoming new contacts, following up with Meta leads, or sending birthday discounts. Abandoned cart and repeat-buyer flows save serious time. You can preview those flows on the free plan, but you'll need a paid plan to launch them. Setup is visual, so it feels more like drag-and-drop than code, which makes automation approachable even for complete beginners.

Plans start free with 500 contacts, then scale based on list size. Paid tiers include Essentials from $13 per month, Standard from $20 per month, and Premium from $350 per month for 10,000 contacts. A Pay As You Go credits plan is useful for infrequent senders. Free trials run for 14 days on paid plans, and nonprofits get 15 percent off.

Mailchimp features include email and SMS campaign builders, prebuilt automation flows, list segmentation, signup forms, landing pages, more than 250 integrations, and a 14-day free trial on paid plans.

HubSpot: Best email marketing software with CRM automation

Bottom line

HubSpot is built for marketers who want their email to work hand-in-hand with CRM data, sales outreach, and long-term customer journeys. That is the biggest advantage during testing, because everything is already connected. Creating an email starts with three options: regular, automated, and blog-triggered. From there, you land inside a clean editor where modules are laid out clearly.

Pros and cons

• Generous free plan
• In-depth guides
• Built-in AI Copilot
• Overwhelming interface for beginners

Expert take

Once you draft your email and select a contact list, you can move toward the automation segment. You can build visual workflows with branching logic, lead scoring, and goal tracking. A campaign can start from a form fill, email click, or even a blog visit. From there, HubSpot handles the branching, including which content goes to which segment, who gets a follow-up, and when to pause. This makes you feel like you are managing a system instead of simply drafting emails.

The reporting tools are better than those found in most platforms. The Analyze and Health tabs give real-time deliverability benchmarks, and you can build custom dashboards that pull metrics from email, sales, and web behavior together. If you need to tie campaign results back to business outcomes, this is the feature to watch.

Copilot is built into the interface on the right-hand side of the editor. You can use it to summarize contact info, research companies, or even rewrite subject lines based on tone. That saves time, especially when you want to clean up the tone of a promo without sounding robotic.

The free plan gives you 2,000 sends per month, which is enough for most small lists. But if you want more complex workflows or want to remove HubSpot branding, you'll need to upgrade to a paid Marketing Hub plan. Paid tiers include Marketing Hub Starter at $9 per month, Marketing Hub Professional at $800 per month with 2,000 contacts included, and Marketing Hub Enterprise at $3,600 per month with 10,000 contacts included. Higher tiers increase send limits based on contact count and unlock dynamic personalization, journey automation, and advanced analytics. Professional onboarding costs an additional $3,000 one-time fee, while Enterprise onboarding starts at $7,000.

HubSpot features include a visual journey builder, deliverability health checks, an AI content assistant, custom dashboards and analytics, list suppression rules, and 2,000 sends per month on the free plan.

MailerLite: Best email marketing software for creators and small teams

Bottom line

MailerLite can help you run email campaigns, create automations based on receiver behavior, develop forms, landing pages, and more. This makes it an all-around marketing tool for getting leads and building a community around your product.

Pros and cons

• Integrates with more than 140 tools
• Built-in landing page builder
• Prebuilt automations
• Low-cost A/B testing
• Doesn't work with Gmail accounts
• Free plan lacks automation templates

Expert take

MailerLite includes a drag-and-drop editor for building simple campaigns. There are multiple options, such as regular, A/B, auto-resend, and RSS. The regular campaign flow comes with a subject line preview pane, email personalization tokens, and sender settings up front, before you even get to design. The editor shows live previews as you tweak blocks, and there is a solid set of content blocks like countdowns, image galleries, and coupon codes. You can save any campaign as a custom template if you want to reuse a layout.

Forms and landing pages are built from the same visual interface, with identical design logic. You can access pop-ups, embedded forms, or full landing pages, and you can edit success messages, trigger timings, and confirmation flows without leaving the visual builder. That is especially useful for testing double opt-in flows, because you can see exactly what users will experience.

MailerLite also offers a dynamic automation setup. You pick a trigger like subscriber joins a group or clicks a link, then build your flow visually. Delays, emails, and conditions are simple drag-and-drop blocks. During testing, we created a three-email onboarding flow with one condition and a time delay in under ten minutes. MailerLite isn't trying to be overly smart, but it gives you all the tools in a manageable, human way.

On the analytics side, all paid plans include open rate, click-through rate, unsubscribes, and heatmaps. The free version doesn't show deep breakdowns or comparative reporting, but it is enough to understand what worked. You can also resend to unopened recipients with one click or schedule an automatic resend.

Plans start with a free tier that supports up to 1,000 subscribers and 12,000 monthly emails. Paid plans start at Growing Business for $10 per month and Advanced for $20 per month. You'll need a paid version for automations, dynamic content, or click maps. MailerLite also offers a 30-day trial of all features on sign-up, so you can use the tool well before committing.

MailerLite features include a drag-and-drop campaign builder, popups and embedded forms, prebuilt and custom automations, a landing page builder, subscriber segmentation, smart resend, A/B testing, and a 30-day premium trial for new users.

Brevo: Best email marketing software for multichannel campaigns

Bottom line

Brevo handles marketing and transactional emails from one unified dashboard. You can start a campaign by naming your email, choosing recipients from a list, and customizing the subject line. Personalization tokens like first name are available right from the subject field, with a fallback built in. For branding, entering a website URL pulls your logo, colors, and fonts automatically. It isn't perfect, but it gets you most of the way there.

Pros and cons

• Beginner friendly
• Smooth list management
• Real-time previews
• Multichannel campaigns
• Limited daily email sends on the free plan
• Custom branding locked behind paid tiers

Expert take

The email builder itself is easy to use. You get full control over blocks, sections, and brand styles. You can drag in a banner image, write a welcome header, and use Brevo's AI assistant to generate paragraph text. The shorten and friendly tone tweaks work well. You can adjust padding, center content, and change button styles with a few clicks. Mobile previews update in real time without refreshing the editor.

You can also test saved templates and reuse custom sections like calls-to-action and image blocks in another campaign. Everything syncs across the Templates tab and the Content Library, so you don't need to rebuild layouts again.

Scheduling options let you send now, schedule later, or use best send time based on engagement. Once live, Brevo shows open, click, bounce, and unsubscribe rates along with heatmaps. It doesn't go as deep into CRM metrics as HubSpot, but for basic and mid-tier needs, the data is easy to access and act on.

Plans start free with a 300-emails-per-day cap. Starter begins at $9 per month and lifts the daily cap, with up to 5,000 emails per month, 24/7 email support, and basic analytics. Removing Brevo's logo is an add-on. Workflows, predictive sending, landing pages, and multiuser access require the Business plan at $18 per month, which also includes A/B testing, advanced stats, and phone support.

Brevo features include more than 150 integrations, over 50 free email templates, predictive sending AI, prebuilt content blocks, and real-time delivery rates.

Klaviyo: Best email marketing software for e-commerce automations

Bottom line

If you're running an e-commerce store, especially on Shopify, Klaviyo is built to handle the retention tactics you'll need once ads start to plateau. Segmentation, automation, and campaign targeting are all wired for online sales.

Pros and cons

• Built for DTC brands
• Email split testing
• Behavioral segmentation
• Helpful AI testing tools
• Not beginner-friendly
• Expensive

Expert take

Klaviyo makes it easy to start with branding, domain authentication, and store syncing, then move into building core flows. The automation section stores prebuilt templates for welcome, cart abandonment, and post-purchase flows. Abandoned checkout flows trigger based on checkout starts and bring in product details dynamically. Add a follow-up reminder and an urgency-based call-to-action, and you can have a high-performing series live in under an hour. You can layer in browse abandonment, win-back, and review request flows using the same interface.

Campaigns are highly detailed. You can build an engaged segment based on open and click activity in the last 60 days, select a campaign template, drop in product images, and track ROI per email sent. Klaviyo shows opens, clicks, conversions, and syncs revenue data from Shopify or WooCommerce.

Signup forms are equally customizable. You can set up a two-step popup with email and SMS fields, target it by device, and delay the trigger for four seconds after load. During testing, a popup with a 10 percent discount offer and a forced click-through for full price increased opt-ins. Each form can be styled separately for mobile and desktop.

Klaviyo has a free plan that includes up to 500 emails per month to 250 profiles. The Email plan starts at $20 per month for 500 profiles and unlocks full reporting dashboards, AI content generation, logo removal, and ongoing support. For predictive analytics and multichannel features, the Email plus SMS plan starts at $35 per month.

Klaviyo features include cross-channel flows, automated smart send time, Shopify and WooCommerce integrations, over 160 customizable email templates, dynamic product content, and over 70 customizable form templates.

What is the best email marketing software?

Mailchimp is the best email marketing software for beginners and small businesses. HubSpot is a great alternative for large-scale businesses that want strong email automations inside a CRM platform. MailerLite is a budget-friendly choice for creators. Brevo is the best tool for multichannel campaigns. Klaviyo is the leader for e-commerce brands that need revenue-focused automations.

Factors to consider when choosing email marketing software

First, think about how you plan to use email. Are you sending a monthly newsletter to a few hundred people? Or are you running dozens of automated flows across segments and syncing with an online store? That baseline makes a huge difference. Mailchimp may be more than enough for a solo creator. But if you need multistep automations, real-time syncing with customer activity, or want to squeeze ROI from every abandoned cart, you'll want something deeper like Klaviyo.

Second, pay attention to contact growth. Every tool looks affordable under 500 contacts, but check what happens when you hit 2,000 or 10,000. Pricing jumps fast if you aren't careful. The cheapest plan at launch may become expensive quickly.

Third, check deliverability and list hygiene. The best platforms help you stay off spam lists, clean inactive subscribers, and improve open rates. HubSpot and Brevo offer strong built-in analytics and suppression tools for this. Fourth, consider AI. Most platforms in 2026 include some kind of AI writer or subject line assistant, but they vary in usefulness. The best tools give suggestions without overdoing it. Brevo and Klaviyo handle this especially well.

Finally, evaluate usability. We measure how much time it takes to go from account signup to first email sent. If it takes more than half an hour and several help documents, that is a bad signal. MailerLite is excellent at fast onboarding, while HubSpot has a steeper learning curve.

How we tested these email marketing tools

We manually tested each app by running actual email campaigns. We created custom signup forms, welcome flows, promotional blasts, and deliverability checks. We built sequences, set up automations, tweaked templates, and reviewed real analytics reports. We paid attention to how long it took to launch a full campaign, how clean the interface felt, how many guides the tool offered, and which features were unlocked after upgrading to paid plans.

Frequently asked questions about email marketing

Is there a free email marketing software?

Yes, Mailchimp, Brevo, MailerLite, and Klaviyo all have free plans with basic features like contact limits, monthly email sends, and access to templates or automations. Free plans are great starting points for beginners or small lists, though most come with limitations such as daily send caps, branded watermarks, or reduced automation features.

Is email marketing still effective in 2026?

Yes, email marketing remains one of the highest ROI channels in 2026. With AI-powered personalization, smart automation, and tighter privacy compliance, it continues to outperform many paid media strategies, especially for nurturing leads and retaining customers.

How many emails can I send without getting marked as spam?

There is no fixed number, but spam filtering depends on sender reputation, engagement rates, and list quality. To avoid spam filters, always use opt-in lists, personalize your content, maintain healthy engagement, and authenticate your domain.
