10 Best Email Marketing Software of 2026

1. 1

   Brevo

   A multichannel marketing platform that prices paid plans by monthly email volume rather than contacts.

   8.8overall

   A multichannel marketing platform that prices paid plans by monthly email volume rather than contacts.

   Best forBudget-minded senders with large contact lists who send occasionally and want email, SMS and WhatsApp in one tool.

   Adoption data

   600KBrevo's company page reports 600,000 customers globally.

   Brevo, About Brevo (2026): “600K Customers globally”

   Brevo prices differently from most rivals, and for some lists that difference is decisive. Its help center describes five plans: Free at $0, Starter from $9 per month, Standard from $18, Professional from $499 and a custom Enterprise tier. The Free plan includes 300 email sends per day and room for up to 100,000 stored contacts, so a large list that mails once a month can stay free or near free. Starter removes the daily cap and is sold in tiers of monthly sends starting at 5,000. Email, SMS and WhatsApp sit in the same account, and transactional email is part of the platform. Brevo reports 600,000 customers, a strong adoption figure for a company outside the US. The limits show up in the details: free sends do not roll over, the Brevo logo stays on Starter emails unless you buy the add-on, and the Professional plan is a large step up.

   Strengths

   • +Lowest verified paid entry price on this list at $9 per month
   • +Pricing by send volume suits large lists that mail rarely
   • +The free plan stores up to 100,000 contacts

   Limitations

   • −The free plan caps sending at 300 emails a day, and unused sends do not carry over
   • −Removing the Brevo logo from emails is an add-on on Starter
   • −Professional jumps to $499 per month

   SummaryBrevo is the best value pick, with the cheapest verified paid plan and a free tier that stores 100,000 contacts. Frequent senders on big lists should price the send tiers carefully.

2. 2

   Mailchimp

   An email and SMS marketing platform priced by contact count with sends set as a multiple of contacts.

   8.8overall

   An email and SMS marketing platform priced by contact count with sends set as a multiple of contacts.

   Best forSmall businesses and online stores that want a widely used platform with a large integration catalog.

   Adoption data

   11 millionMailchimp says 11 million businesses choose its platform, the largest business count published by any vendor on this list.

   Mailchimp, Mailchimp homepage (2026): “Discover why 11 million businesses choose Mailchimp.”

   Mailchimp remains the reference point for small business email. Its pricing page in USD lists Essentials from $13 per month, Standard from $20 and Premium from $350, each scaled by contact count, with a 14-day trial on the two lower plans and a basic Free plan for lists under 250 contacts. The send allowance is unusually transparent: 10 times your contact count per month on Essentials, 12 times on Standard and 15 times on Premium. Standard adds the automations, personalization and generative AI tools most growing senders want, and the integration catalog lists more than 300 apps, including Shopify, WooCommerce and Stripe. Mailchimp's homepage says 11 million businesses choose it, which gives it the strongest adoption signal here. The trade-offs are cost at scale and overage fees when a list grows past its tier. Teams with large lists should model Premium pricing early, since the jump from Standard is steep.

   Strengths

   • +Largest published business count in this comparison
   • +Send allowance is stated plainly as a multiple of contacts
   • +Pay As You Go email credits for infrequent senders

   Limitations

   • −The free plan only covers businesses with fewer than 250 contacts
   • −Overages apply when contact or send limits are exceeded
   • −Premium starts at $350 per month, a big step up from Standard

   SummaryMailchimp ranks first on reach, clear send limits and a $13 entry plan. Watch the overage fees and the jump to Premium as lists grow.

3. 3

   MailerLite

   An email marketing tool for creators and small businesses with a website builder, landing pages and paid subscriptions built in.

   8.6overall

   An email marketing tool for creators and small businesses with a website builder, landing pages and paid subscriptions built in.

   Best forSolo founders, creators and small teams that want a low-cost plan with automations, landing pages and a site builder.

   Adoption data

   1 millionMailerLite's homepage says more than 1 million creators and businesses use the product.

   MailerLite, MailerLite homepage (2026): “Join 1M+ creators and businesses using MailerLite to grow.”

   MailerLite packs more into its low tiers than most of its rivals. The pricing page lists four plans: Free, Comfort, Power and Enterprise. Free covers 250 subscribers, 2 user seats and 2,500 monthly emails, and still includes campaigns, automations, a website, a landing page, signup forms and all three editors. Comfort starts at $12 per month and adds unlimited templates, dynamic emails, campaign auto-resend, multivariate testing and preference center tools. Stripe support lets creators sell paid newsletters and digital products without another tool. The homepage says more than 1 million creators and businesses use MailerLite, a solid adoption signal for a team of about 160 people. The constraints are mostly about scale. The free tier is small, API sending is reserved for paid plans, and the channel mix is narrower than all-in-one platforms that bundle SMS or WhatsApp. For a newsletter or a small store, those limits rarely matter.

   Strengths

   • +Automations and a website are included even on the free plan
   • +Comfort at $12 per month is one of the cheapest full toolsets here
   • +All three email editors are available on every plan

   Limitations

   • −The free plan is small at 250 subscribers
   • −Sending through the API or MCP server requires a paid plan
   • −Fewer native channels than Brevo or Klaviyo

   SummaryMailerLite gives small senders automations, landing pages and a site builder for $12 per month. It ranks third because its channel range is narrower than the leaders.

4. 4

   Klaviyo

   A B2C CRM and marketing platform for ecommerce brands that combines email, SMS, customer data and analytics, priced by active profiles.

   8.4overall

   A B2C CRM and marketing platform for ecommerce brands that combines email, SMS, customer data and analytics, priced by active profiles.

   Best forEcommerce brands that want email and SMS driven by purchase and browsing data.

   Adoption data

   205,000Klaviyo reports more than 205,000 paying customers in over 100 countries on its company page.

   Klaviyo, About Klaviyo (2026): “205,000+ paying customers in 100+ countries”

   Klaviyo is the specialist pick for online stores. Its own comparison page states that paid email plans start at $20 per month, and pricing is based on active profiles, meaning the people you actually market to rather than everyone on the list. The free plan covers 250 profiles, 500 email sends and $5 of mobile messages per month, enough to set up flows before paying. Multi-step flows are included on every plan, and the platform now spans a customer data platform, reviews, a customer hub and AI agents under the Composer name. Klaviyo's company page reports more than 205,000 paying customers in over 100 countries, which is a paying count rather than a sign-up total. The downside is that it is more product than a newsletter needs: Klaviyo says there is more of it to learn, and its entry price is higher than Brevo, MailerLite or Mailchimp Essentials. For stores with real order data, the segmentation usually justifies the cost.

   Strengths

   • +Inactive profiles do not raise the bill, according to Klaviyo
   • +Deep ecommerce data model for segmentation and flows
   • +Strong paying customer count among ecommerce platforms

   Limitations

   • −Entry price of $20 per month is above most rivals
   • −More to learn than a basic newsletter tool, as Klaviyo itself notes
   • −The free plan allows only 500 email sends per month

   SummaryKlaviyo is the strongest choice for ecommerce email and SMS, backed by a large paying customer base. Non-commerce senders will pay for data tools they do not need.

5. 5

   ActiveCampaign

   A marketing automation platform built around multi-step workflows, with plans sized by contacts and a fixed monthly send allowance.

   8.2overall

   A marketing automation platform built around multi-step workflows, with plans sized by contacts and a fixed monthly send allowance.

   Best forSmall and midsize teams that need advanced automation and CRM features more than the lowest price.

   Adoption data

   180,000ActiveCampaign says its platform helps more than 180,000 customers.

   ActiveCampaign, About ActiveCampaign (2026): “ActiveCampaign’s intelligent marketing automation platform helps over 180,000 customers get more out of their marketing and sales campaigns.”

   ActiveCampaign is the automation-first option in this group. Its pricing page shows Starter at $15 per month billed yearly for 1,000 contacts, Plus at $49, Pro at $79 and Enterprise at $145, and it publishes send allowances plainly: 10,000 sends per month on Starter and Plus at that contact level, 12,000 on Pro and 15,000 on Enterprise. Every plan includes multi-step automation. Plus adds cross-channel marketing, generative AI and landing pages, while Pro brings predictive send times, conditional content and attribution tracking. The about page says the platform helps more than 180,000 customers. The weak points are cost per seat and the lack of a free plan. Starter has one user seat, and the features many teams expect, such as landing pages, sit on Plus. For teams that live in workflows, the trade is reasonable, and the company offers a refund if a buyer is not satisfied after 30 days.

   Strengths

   • +Published send limits per plan make volume planning simple
   • +Automation depth starts on the cheapest plan
   • +Refund offer if not satisfied after 30 days

   Limitations

   • −No permanent free plan
   • −Starter includes only 1 user seat
   • −Landing pages and generative AI require Plus at $49 per month

   SummaryActiveCampaign has the deepest automation on this list and clear send limits per plan. It ranks fifth because there is no free plan and useful features start on Plus.

6. 6

   Omnisend

   An email, SMS and web push platform for ecommerce stores, with AI tools for forms, content and reports.

   8.1overall

   An email, SMS and web push platform for ecommerce stores, with AI tools for forms, content and reports.

   Best forSmall and midsize online stores that want ecommerce automation at a lower price than Klaviyo.

   Adoption data

   150KOmnisend's homepage says more than 150,000 ecommerce brands trust the platform.

   Omnisend, Omnisend homepage (2026): “Trusted by 150K+ ecommerce brands.”

   Omnisend targets the same stores as Klaviyo at a lower price. Its pricing page lists a Free plan with 500 emails a month and 250 contacts, a Standard plan with 6,000 emails a month at 500 contacts, and a Pro plan with unlimited monthly emails and SMS from $0.007 per message. Read the Standard price carefully: the page shows $11.20 per month, but that reflects a 30% discount on the first three months, which total $48 at list price, or $16 a month. Web push notifications are included on every plan, and AI tools build forms, content and reports from prompts. The homepage says more than 150,000 ecommerce brands trust Omnisend, and the company lists more than 335 integrations. It is a sensible choice for stores that want flows and campaigns without Klaviyo's price, though SMS is limited to Pro and the adoption base is smaller than the top names.

   Strengths

   • +Ecommerce focus at a lower entry price than Klaviyo
   • +Web push included on every plan
   • +Free migration help

   Limitations

   • −Headline price on the pricing page is a three-month discount
   • −SMS requires the Pro plan
   • −Smaller reported customer base than the leaders

   SummaryOmnisend gives online stores email, web push and automation from $16 per month at list price. It trails Klaviyo on data depth and customer count.

7. 7

   GetResponse

   An email marketing platform with unlimited sends on every paid plan, priced by list size.

   8.0overall

   An email marketing platform with unlimited sends on every paid plan, priced by list size.

   Best forSenders who mail often and want unlimited monthly sends priced by list size.

   Adoption data

   350,000GetResponse reports more than 350,000 customers in 183 countries.

   GetResponse, About GetResponse (2026): “350,000+ customers worldwide”

   GetResponse sells on send volume. Its pricing page says monthly plans are bracketed by list size and start at $19 per month for unlimited messages to 1,000 subscribers, with an 18% discount for 12-month billing. Starter includes AI content generators, a welcome series, one custom automation workflow, a landing page builder, signup forms and SMS marketing, and GetResponse says each Starter account allows three users. Marketer is aimed at ecommerce businesses selling across channels, and a custom Enterprise tier sits at the top. The about page reports more than 350,000 customers in 183 countries and more than 25 years on the market. The case against it is price at the low end: Brevo, MailerLite and Mailchimp all start below $19 and offer permanent free plans, while GetResponse now offers only a 14-day trial. For brands that mail daily, unlimited sends at a fixed list price can still work out cheaper than send-capped plans.

   Strengths

   • +Unlimited sends remove volume worries for frequent mailers
   • +18% discount on 12-month plans
   • +Three users included from the entry plan

   Limitations

   • −No permanent free plan, only a 14-day trial
   • −Starter starts at $19, above most rivals
   • −Starter includes only 1 custom automation workflow

   SummaryGetResponse suits frequent senders who want unlimited sends priced only by list size. The lack of a free plan and the $19 entry point keep it mid-table.

8. 8

   HubSpot Marketing Hub

   The marketing module of HubSpot's customer platform, combining email, forms, landing pages and automation on a shared CRM.

   8.0overall

   The marketing module of HubSpot's customer platform, combining email, forms, landing pages and automation on a shared CRM.

   Best forCompanies that already use HubSpot CRM or want marketing and sales on one customer record.

   Adoption data

   306,000HubSpot reports 306,000 customers across its platform, which covers more than marketing.

   HubSpot, HubSpot: Our Story (2026): “306,000 Customers”

   HubSpot Marketing Hub makes most sense as part of the wider HubSpot platform. The pricing page shows free tools that include 2,000 email sends per calendar month with HubSpot branding, and every paid tier removes that send limit. Starter, Professional and Enterprise add more segments, branding removal, workflows, custom reports and, at the top, a sandbox account. The key advantage is the shared CRM: campaigns, forms and landing pages write to the same contact record that sales and service teams use. HubSpot reports 306,000 customers, though that figure covers all of its hubs rather than email alone. We could not confirm USD prices because the pricing page shows euros from our location, so treat cost as unverified. HubSpot's own page shows large jumps between tiers, which is the main reason it ranks below cheaper dedicated tools despite strong features.

   Strengths

   • +Marketing, sales and service data in one CRM
   • +Free tools let teams start without a card
   • +Large reported customer base across the platform

   Limitations

   • −USD prices could not be confirmed from this location
   • −Professional and Enterprise tiers carry steep jumps in cost
   • −Free sends carry HubSpot branding

   SummaryHubSpot Marketing Hub is the pick for teams that want email on the same CRM as sales. Its USD price is pending, and costs climb fast on higher tiers.

9. 9

   Constant Contact

   An email and digital marketing platform for small businesses, nonprofits and franchises, with live onboarding and phone support.

   7.9overall

   An email and digital marketing platform for small businesses, nonprofits and franchises, with live onboarding and phone support.

   Best forSmall businesses and nonprofits that value live onboarding and phone support over the lowest price.

   Adoption data

   460KConstant Contact's homepage says more than 460,000 small businesses, nonprofits and franchises trust it with their marketing.

   Constant Contact, Constant Contact homepage (2026): “Join the 460K+ small businesses, nonprofits, and franchises who trust Constant Contact with their marketing.”

   Constant Contact leans on service more than features. The pricing page lists Lite from $10.20 per month billed annually, Standard from $29.75 and Premium from $68, with each price based on contacts and email sends and overage fees possible. Every plan includes live 1:1 onboarding, and live phone and chat support is part of the offer, which few rivals match at this price. Social posting to Facebook, Instagram and LinkedIn is built in, and SMS can be added to Lite or Standard from $10 per month, while Premium includes 500 messages. Nonprofits can save up to 30% by prepaying. The homepage says more than 460,000 small businesses, nonprofits and franchises use it. The weaknesses are a missing free plan and the gap between Lite and the automation tools on Premium. Owners who want help on the phone will find it worth the price; self-serve senders can do more for less elsewhere.

   Strengths

   • +Live onboarding with experts is included from Lite
   • +Phone support suits owners who prefer to talk
   • +Up to 30% prepay discount for nonprofits

   Limitations

   • −No free plan
   • −Plan prices depend on contacts and sends, and overage fees may apply
   • −Premium, at $68, is where the most advanced automation and segmentation tools sit

   SummaryConstant Contact is the support-first choice for small businesses and nonprofits. It ranks ninth because automation depth costs $68 a month and there is no free plan.

10. 10

    Kit

    An email platform for creators with a free plan up to 10,000 subscribers and tools to sell digital products.

    7.3overall

    An email platform for creators with a free plan up to 10,000 subscribers and tools to sell digital products.

    Best forCreators and newsletter writers who want a large free plan and built-in selling.

    Kit is built for creators, and its pricing reflects that. The Free plan allows up to 10,000 subscribers with unlimited landing pages, forms and email broadcasts, plus tagging, segmentation and tools to sell digital products and subscriptions. That is the largest free allowance in this comparison. Paid plans are steeper: Creator costs $33 per month on yearly billing for 1,000 subscribers, or $390 a year, and Pro is offered at $50 per month for the first year on a limited-time deal. Paying yearly saves 17%, and migrations are free. The weaker part of the case is adoption data. We did not find a current user count published on Kit's own pages, so its adoption score is conservative. For writers who mainly broadcast to a growing list and sell a few products, Kit's free tier can carry a long way before the higher paid prices matter.

    Strengths

    • +Largest free subscriber allowance on this list
    • +Selling tools are part of the free plan
    • +Free migrations and a 14-day trial with no card

    Limitations

    • −Creator at $33 per month for 1,000 subscribers is pricey
    • −No citable current user count on Kit's own pages
    • −Built for creators rather than stores or B2B teams

    SummaryKit has the most generous free plan here at 10,000 subscribers, aimed squarely at creators. Its paid plans cost more than rivals and it lacks a published user count.
