Kit

Here are the email marketing platforms I’d actually shortlist in 2026, based on brand adoption, real-world popularity, and fit by business type—not just “best software” lists.

1. Mailchimp — best default for small businesses and general-purpose email marketing
2. Klaviyo — best for Shopify/ecommerce brands

7. Constant Contact — best for local businesses, nonprofits, events, and beginners
8. Kit — best for creators, coaches, bloggers, and newsletter-led businesses
9. Salesforce Marketing Cloud / Braze — best for enterprise lifecycle marketing

Best brands by use case

Mailchimp — best all-around default

If you want a safe, widely used option that most marketers recognize, start with Mailchimp. It’s strong for newsletters, basic automations, templates, ecommerce integrations, landing pages, and small-business campaigns. Mailchimp says it has 11M+ global users, 300+ integrations, and 50+ behavior-based triggers, which is why it remains one of the most common defaults for smaller teams. (mailchimp.com)
Choose it if: you want easy setup, decent automation, and broad integrations.
Skip it if: you need very advanced ecommerce segmentation or complex B2B lead nurturing.

Klaviyo — best for ecommerce

For ecommerce—especially Shopify, WooCommerce, and direct-to-consumer brands—Klaviyo is usually the strongest pick. It’s built around customer profiles, purchase behavior, abandoned-cart flows, product recommendations, segmentation, SMS, WhatsApp, and revenue attribution. Klaviyo reported over 193,000 customers at the end of fiscal 2025, up from 167,000 the prior year. (investors.klaviyo.com)
Choose it if: you run an online store and email/SMS revenue matters.
Skip it if: you just need a simple newsletter tool; it can feel expensive or overbuilt.

HubSpot Marketing Hub — best for B2B + CRM

If email marketing is part of a broader sales funnel—lead capture, CRM, landing pages, forms, sales handoff, reporting, and nurture campaigns—HubSpot is one of the best choices. HubSpot reported 288,706 customers as of December 31, 2025, and its platform includes a CRM plus marketing, sales, service, content, and operations tools. (ir.hubspot.com)
Choose it if: you sell services, SaaS, consulting, B2B products, or anything with a sales pipeline.
Skip it if: you only need cheap newsletters; HubSpot can get pricey as you scale.

ActiveCampaign — best for automations

ActiveCampaign is a great middle ground between Mailchimp simplicity and HubSpot/Klaviyo depth. It’s especially strong for visual automations, segmentation, lead scoring, tagging, CRM-lite sales workflows, and lifecycle campaigns. ActiveCampaign says its platform helps over 180,000 customers with marketing and sales campaigns. (activecampaign.com)
Choose it if: you want sophisticated automations without going full enterprise.
Skip it if: your team wants the simplest possible newsletter builder.

Brevo — best value for email + SMS/WhatsApp

Brevo, formerly Sendinblue, is a strong budget-conscious option for email, SMS, WhatsApp, transactional email, CRM-lite features, and multichannel campaigns. Brevo’s 2026 benchmark referenced messaging data from 175,000 businesses globally, which suggests real scale among SMBs and mid-market teams. (globenewswire.com)
Choose it if: you want good features for the price, especially if you send across multiple channels.
Skip it if: you want best-in-class ecommerce attribution or a polished enterprise CRM.

Omnisend — best ecommerce alternative to Klaviyo

Omnisend is popular with ecommerce brands that want email + SMS automation but find Klaviyo too expensive or complex. It emphasizes ecommerce automation, segmentation, reporting, push notifications, and prebuilt store workflows. Omnisend says it has 150K+ customers worldwide and sent 27B emails in 2025. (omnisend.com)
Choose it if: you run an ecommerce store and want strong automation without Klaviyo’s cost/complexity.
Skip it if: you’re B2B or need deep CRM/sales pipeline tools.

Constant Contact — best beginner-friendly option

Constant Contact is a long-running, beginner-friendly option for local businesses, nonprofits, churches, schools, restaurants, gyms, events, and service businesses. G2’s 2026 email marketing review named it the best email marketing software for small businesses, highlighting templates, automation, and analytics. (learn.g2.com)
Choose it if: ease of use and support matter more than advanced automation.
Skip it if: you need sophisticated segmentation, ecommerce logic, or custom workflows.

Kit — best for creators

Kit, formerly ConvertKit, is best for creators: newsletter writers, course sellers, coaches, podcasters, authors, bloggers, and solo experts. Its strengths are simple publishing, landing pages, forms, sequences, tags, creator monetization, and selling digital products. The company rebranded from ConvertKit to Kit to focus more broadly on professional creators. (businesswire.com)
Choose it if: your business is audience-first or newsletter-first.
Skip it if: you need ecommerce product catalog automation or a full CRM.

Salesforce Marketing Cloud / Braze — best enterprise choices

For large companies with high-volume lifecycle messaging, complex data, apps, loyalty programs, multiple brands, and enterprise compliance needs, look at Salesforce Marketing Cloud Engagement, Braze, Iterable, or Adobe Journey Optimizer. Braze, for example, reported 2,713 customers and 8.5B monthly active users reached through customer apps/sites as of April 30, 2026. (investors.braze.com)
Choose these if: you have a lifecycle marketing team, data engineers, and high-scale personalization needs.
Skip them if: you’re a small business; they’re usually overkill.

My practical shortlist

If I had to pick one

• Most businesses: Mailchimp
• Most ecommerce stores: Klaviyo
• Most B2B companies: HubSpot
• Best automation value: ActiveCampaign
• Best budget/value: Brevo
• Best creator platform: Kit

One note: if you mean cold email outreach, that’s a different category. Tools like Instantly, lemlist, Apollo, or Smartlead are used for outbound prospecting, while Mailchimp/Klaviyo/HubSpot/etc. are primarily for permission-based email marketing.

The "best" email marketing software is not a one-size-fits-all solution. The platform that is perfect for an e-commerce giant will be a terrible, overpriced fit for a solo blogger.

To help you find the software that fits your workflow, the top platforms that people actually use are categorized below by who they are best for.

1. For Creators, Bloggers & Educators: Kit (formerly ConvertKit)

In late 2024, ConvertKit rebranded to Kit to reflect its evolution into an "all-in-one operating system" for creators.

• Why people use it: If you sell digital products, courses, or coaching, Kit is the gold standard. It treats subscribers as unique profiles rather than placing them in separate lists (which prevents you from paying for the same subscriber twice).
• Standout features: It has a highly advanced visual automation builder that lets you easily segment users based on link clicks, digital purchases, or lead magnets.
• Best for: Bloggers, YouTubers, course creators, and authors who want to run automated sales funnels.

2. For High-Growth Newsletters: Beehiiv

Beehiiv has quickly become the hottest competitor in the newsletter space, specifically targeting publishers looking to grow and monetize.

• Why people use it: Unlike older marketing tools, Beehiiv was built specifically for publishing and scaling newsletters. It features flat-rate pricing (meaning you don’t get penalized with massive price hikes as your list grows) and highly effective growth features.
• Standout features: Its Recommendation Network allows you to partner with other creators to recommend each other’s newsletters upon sign-up, which is a massive organic growth engine. It also has a native ad network and seamless paid subscription options built-in.
• Best for: Dedicated newsletter writers, media companies, and publishers focused on rapid audience growth and ad monetization.

3. Best Value & Budget-Friendly: MailerLite

• Why people use it: MailerLite is universally praised for being incredibly intuitive and offering the best "bang for your buck". It doesn't look like bloated software from the early 2000s; it has a clean, drag-and-drop interface that makes designing clean emails a breeze.
• Standout features: Its free plan is incredibly generous and includes access to advanced features like landing page builders, list segmentation, and basic automation.
• Best for: Small businesses, freelancers, and beginners who want professional features without a steep learning curve or high monthly fees.

4. For E-commerce Brands: Klaviyo

• Why people use it: If you run an online store (especially on Shopify, WooCommerce, or Magento), Klaviyo is the undisputed industry standard. It integrates deeply with your store to track exact customer purchasing behaviors.
• Standout features: Highly sophisticated e-commerce automations. Klaviyo makes it incredibly easy to set up dynamic "abandoned cart" flows, "browse abandonment" flows, and personalized post-purchase follow-ups based on the exact items a customer bought. It also handles SMS marketing seamlessly.
• Best for: E-commerce stores looking to aggressively drive sales and track precise ROI. (Runner up: Omnisend, which is a highly rated, slightly cheaper alternative to Klaviyo).

5. For Complex Automation & B2B: ActiveCampaign

• Why people use it: If your marketing depends on highly complex customer journeys, scoring leads, and aligning with a sales team, ActiveCampaign is unmatched.
• Standout features: It features some of the most advanced conditional automation builders on the market, paired with built-in CRM capabilities. You can track how users interact with your actual website and trigger highly specific sales follow-ups.
• Best for: B2B businesses, SaaS companies, and digital marketers who need enterprise-grade CRM and multi-step marketing automation.

6. Best Scale & Multi-Channel: Brevo (formerly Sendinblue)

• Why people use it: Unlike almost every other email platform, Brevo does not charge you based on how many subscribers are on your list. Instead, they charge based on the number of emails you actually send.
• Standout features: Aside from standard newsletters, Brevo is fantastic for transactional emails (order confirmations, shipping notifications, password resets). It also packages SMS, WhatsApp marketing, and on-site chat under one roof.
• Best for: Businesses with large contact lists who only email them occasionally, or those who need a reliable platform to handle both marketing and transaction emails.

What about Mailchimp?

Historically, Mailchimp is the most widely recognized brand in email marketing. While many people still use it because of brand recognition, the general consensus among modern marketers is that its value has declined. Its pricing has risen significantly, and they have heavily restricted what is allowed on their free tier. While it is still a solid, highly polished tool with a great template editor, most modern users now opt for MailerLite (for budget) or Kit (for features) instead.

How to Choose:

• If you want a free, easy, and affordable all-rounder: MailerLite
• If you are a creator selling digital products/courses: Kit
• If you want to build and monetize a newsletter: Beehiiv
• If you run a Shopify/E-commerce store: Klaviyo
• If you need sales CRM and elite automations: ActiveCampaign

The best email marketing software for most businesses are ActiveCampaign, HubSpot, Mailchimp, Brevo, Klaviyo, Omnisend, Constant Contact, and Kit. Which one is “best” depends on whether you’re running an ecommerce store, a startup, a creator business, or a general small business.

• ActiveCampaign — best overall for growing businesses and advanced automation
• HubSpot Marketing Hub — best all-in-one marketing platform and a top overall pick in tested reviews
• Mailchimp — best for beginners and simple email marketing
• Brevo — best for budget-conscious businesses and multichannel campaigns
• Klaviyo — best for ecommerce and data-driven automation
• Omnisend — best for ecommerce email marketing, especially for online stores
• Constant Contact — best for small businesses that want an easier, mainstream option
• Kit — best for creators and newsletter-style businesses

If you want the most practical shortlist of products people actually use:

• ActiveCampaign if you want the strongest automation and CRM-style features
• Mailchimp if you want the most familiar beginner-friendly option
• HubSpot if you want email inside a broader marketing suite
• Klaviyo or Omnisend if you sell online and need ecommerce integrations
• Brevo if you want a strong lower-cost option with email plus SMS

If you want, I can also give you a top 5 by use case or a free-only options list.

The best email marketing software depends on your needs (e.g., e-commerce, small business basics, advanced automation, newsletters/creators, budget, or all-in-one CRM), but several brands dominate real-world usage based on market presence, user numbers, review sites (G2, Capterra), expert tests, and popularity among businesses.

Mailchimp remains the most widely recognized and used overall. Specialists like Klaviyo lead in e-commerce, while options like Brevo and MailerLite excel for affordability and ease. Here’s a breakdown of the top recommendations that people and businesses actually use, drawn from 2024–2026 reviews, market data, and comparisons.

Quick Comparison Tips

• E-commerce revenue focus: Klaviyo or Omnisend.
• Advanced automation without enterprise cost: ActiveCampaign.
• Easy and familiar: Mailchimp.

• Consider deliverability (all major ones are solid if you maintain list hygiene), ease of use, specific integrations (e.g., Shopify), support, and scalability. Look at recent G2/Capterra reviews for your industry, and migrate carefully (some offer free help).

These are the brands businesses actually adopt and stick with, per usage stats, review volume, and expert consensus. Test 2–3 with your real list and use cases before committing, as “best” is highly contextual.
