The best email marketing software in 2026
We ranked six platforms by what they actually cost at your list size and whether the email reaches the inbox, not by who has the bigger logo.
Almost every “best email software” list ranks tools by brand recognition and the price on the signup page. Both are the wrong number. The signup price is for 500 contacts you will outgrow in a month, and the brand you have heard of (Mailchimp) is usually the most expensive at scale with mediocre deliverability. The two figures that decide whether email pays off are the price at your list size and the independently tested inbox rate, and on both, the cheapest capable tools tend to win. This guide ranks the six platforms most US senders shortlist using verified pricing, real third-party deliverability tests, and large-sample buyer ratings, so the tool that gives you the most for the least sits at the top.
How we picked
We score every tool on real value first, then performance, satisfaction, and capability. Here is the order of what matters, most decisive to least, and why most lists get it backwards.
1. Deliverability, measured independently. This is the only metric that determines whether you get paid for an email, and it is the one vendors fudge. EmailToolTester has run seed-list inbox tests for over five years. Their latest all-platform average inbox rate is about 83.1 percent. They call anything above 89 percent excellent and 83 to 88 percent acceptable. Note the trap: a “delivery rate” only means the receiving server accepted the message, not that it reached the inbox. Kit advertises 99.8 percent delivery and 99.4 percent inbox placement but does not submit to independent seed tests, so treat those as marketing, not a true inbox rate. Validity’s 2025 benchmark puts the real global average inbox rate at 83.5 percent, which tells you any 99 percent vendor claim is not an inbox figure.
2. Real cost at scale, not the entry price. Pricing is contact-based for most of these tools and email-volume-based for Brevo, and it climbs steeply. A $13 to $20 starter plan is irrelevant. Model the price at your actual list, say 10,000 or 25,000 contacts, and watch for overage fees, charges on unsubscribed or inactive contacts (Mailchimp’s well-known trap), and features locked behind a higher tier.
3. Automation depth. “Automation” ranges from a single linear autoresponder (Kit’s free plan) to multi-step behavioral journeys across email, SMS, and your website (ActiveCampaign, Brevo, GetResponse). Buy for the funnels you actually run, not the ones in the demo.
4. Pricing model fit. Contact-based pricing (MailerLite, Kit, ActiveCampaign, GetResponse, Mailchimp) punishes a large dormant list. Email-volume pricing (Brevo) rewards a big list you email infrequently. The right model can halve your bill.
5. Independent ratings. We weight G2 and Capterra, which verify business buyers and carry large samples, above Trustpilot, which skews toward angry consumers and billing complaints (notice how every brand scores far lower there). We also read recent one-star reviews for the real failure modes: surprise billing, account suspensions, and gated support.
6. Everything else. Editor and template quality, ease of use, native integrations and API, support tier (live chat is often locked to higher plans), and GDPR and CAN-SPAM consent tooling.
At a glance: ranked best value first
| Tool | Lab Score | From | Cost at scale | Best for |
|---|---|---|---|---|
| MailerLite | 9.1 | $10/mo | ~$50 to $90/mo at 10k | Creators and small businesses that want low cost, ease, and strong inboxing |
| Kit | 8.8 | Free / $39/mo | ~$199/mo at 25k (Creator) | Creators and newsletters that monetize an audience |
| ActiveCampaign | 8.7 | $15/mo | ~$1,169/mo at 50k (Enterprise) | Teams that need deep automation plus a CRM and will use it |
| Brevo | 8.5 | Free / $9/mo | ~$499/mo at high volume | Large lists emailed infrequently, plus SMS and WhatsApp |
| GetResponse | 8.3 | $15.58/mo | ~$79/mo at 10k | One tool for email, funnels, and native webinars |
| Mailchimp | 7.6 | $13/mo | ~$100/mo at 5k (Standard) | Very small teams already inside the Intuit ecosystem |
1. MailerLite
MailerLite earns a Lab Score of 9.1 because it has the best price-to-quality ratio in the category, and it is not close. The interface is genuinely clean, the free tier covers up to 500 subscribers and 12,000 emails a month (cut from 1,000 subscribers in September 2025), and paid plans start at $10 a month on Growing Business with Advanced from $20. At scale it stays reasonable: roughly $50 to $90 a month at 10,000 subscribers depending on features, about $21 to $36 at 2,500, and around $289 a month on Growing Business at 50,000. Annual billing saves about two months.
The reason it tops the list is performance backed by independent data. MailerLite averages about 94.4 percent inbox placement across EmailToolTester’s last five rounds and holds their Best of 5 deliverability award, with single rounds ranging from about 89.8 percent up. That is among the very best measured, and well above the 83.1 percent all-platform average. Buyers agree: Capterra 4.7 out of 5 across about 2,254 reviews, G2 4.6, and Trustpilot about 4.6, which is rare for this category. Plans also bundle free websites, landing pages, and blogs.
The main weakness is depth: automation and reporting are thinner than ActiveCampaign or GetResponse, and the strict manual account-approval and anti-spam review can delay or reject signups. It is not built for heavy e-commerce or complex CRM journeys. It suits solopreneurs, creators, bloggers, small businesses, and newsletters that want low cost, ease, and strong inboxing without heavy automation.
2. Kit
Kit (formerly ConvertKit) scores 8.8 as the pick for creators who treat their list as a business. The free Newsletter plan covers up to 10,000 subscribers with unlimited emails, forms, and landing pages, though only one automation. Paid Creator starts at $39 a month ($33 annual) at 1,000 subscribers and Creator Pro at $79 ($66 annual), after prices rose about 35 percent in October 2025 (Creator $29 to $39, Pro $59 to $79). At scale it adds up: 5,000 subscribers cost $89 a month on Creator or $139 on Pro, and 25,000 run $199 or $279.
What you pay for is the model. Kit is built around tagging and segmenting subscribers rather than lists, with clean automations and real monetization tools: paid newsletters, digital products, and the Creator Network for recommendations. Ratings hold up: G2 4.4 across about 217 reviews and Capterra 4.6 across about 239. Trustpilot is split: the newer kit.com profile around 4.2 (about 112 reviews) versus a poor 1.9 for the legacy convertkit.com profile. On deliverability, Kit self-reports about 99 percent but does not take part in independent seed tests, so it is not comparable to the ~94 percent figures above and should be treated with caution.
The weakness is design: only about 15 to 23 basic templates and clunky visual building, and the bill grows fast as your list does. E-commerce and CRM depth is limited. It suits creators, course sellers, authors, coaches, and newsletter operators who value subscriber relationships and monetization over polished templates.
3. ActiveCampaign
ActiveCampaign takes an 8.7. It would rank higher on capability alone, but cost at scale pulls it back. Starter runs $15 a month on annual billing ($19 monthly) at 1,000 contacts. Monthly rates at that tier are Starter $19, Plus $59, Pro $99, and Enterprise $179, with extra emails about $0.005 each and roughly 20 percent off for annual. The catch is escalation: pricing climbs steeply with contacts and Enterprise reaches about $1,169 a month at 50,000 contacts, while the Starter, Plus, Pro, and Enterprise tiers gate the automation and CRM features many buyers actually came for.
What you get is the deepest automation in this group: true visual multi-step behavioral journeys, branching, and lead scoring, plus a built-in CRM and strong native integrations. Performance matches the ambition. ActiveCampaign hit about 94.2 percent in EmailToolTester’s latest round, reclaiming the number one spot and their Best email deliverability award, the top of the category. The buyer signal is enormous: G2 4.5 across more than 14,500 reviews, one of G2’s most-reviewed products, with about 95 percent rating it four or five stars, and Capterra 4.6. Trustpilot is only 2.8 (average), reflecting billing and support friction.
The weakness is the flip side of the strength: a steep learning curve, contact-based pricing plus feature-gating that balloons the real bill, and clear overkill for a simple newsletter. It suits SMB to mid-market and B2B teams that need sophisticated automation and a CRM and will genuinely use the depth.
4. Brevo
Brevo (formerly Sendinblue) scores 8.5 and is the value outlier for one specific shape of list. It is priced on email volume, not contacts, so the free plan gives you 300 emails a day with unlimited contacts. Starter is $9 a month (5,000 emails), Standard $18 (adding landing pages, multi-user, and priority email support), and Professional around $499 for higher monthly-volume tiers in some sources, with Enterprise custom. Because billing follows emails sent, a large list you email occasionally is dramatically cheap, which is exactly the lever most pricing pages hide.
The other draw is breadth in one place: email plus SMS, WhatsApp, transactional email, and a built-in CRM, true multichannel rather than email with bolt-ons. Ratings are solid: G2 4.5 across about 2,637 reviews, Capterra 4.6 across about 3,414, and Trustpilot 4.1 (great), notably higher than the incumbents.
The reason it sits mid-pack rather than top is deliverability. Brevo landed about 88.3 percent in EmailToolTester’s latest round, eighth of fifteen, rated acceptable and trending up slightly over the last two rounds but clearly below MailerLite and ActiveCampaign. Other weaknesses: the daily send cap on the free plan, add-ons that stack up, and templates and UI less polished than MailerLite. It suits small and mid businesses and e-commerce that want multichannel and transactional email together, especially those with large lists they email infrequently.
5. GetResponse
GetResponse earns an 8.3 as the broadest all-in-one at a mid price. The Email Marketing Starter plan runs $15.58 a month on annual billing ($19 monthly) at 1,000 subscribers, with unlimited emails, autoresponders, landing pages, and 24/7 chat. Marketing Automation starts around $59 a month and Ecommerce Marketing around $119 at 1,000 subscribers. At scale it is fair: about $29 a month at 2,500 contacts, $79 at 10,000, and the Max plan from $165 at 100,000-plus, with annual saving roughly 18 to 20 percent. The asterisk: automatic overage charges kick in when you pass your contact tier.
The pitch is the feature set. GetResponse bundles email, marketing automation, landing pages, conversion funnels, native webinars (genuinely rare in this category), and AI tools in one subscription, and deliverability is strong: about 90.9 percent in EmailToolTester’s latest round, third of fifteen and rated excellent, just behind ActiveCampaign and MailerLite. Ratings are good if a notch below the leaders: G2 4.3 across about 821 reviews, Capterra 4.2 across about 516, and Trustpilot 4.2 across about 955, though that last one is bimodal at roughly 63 percent five-star against 27 percent one-star, a love-it-or-hate-it split driven mostly by billing.
The weaknesses are the surprise overage fees, the jack-of-all-trades reality where each module is slightly less deep than a specialist, and the higher tiers needed for the best automation. It suits small and mid businesses and course or webinar sellers who want email, funnels, and webinars in one tool instead of three.
6. Mailchimp
Mailchimp (now part of Intuit) lands at 7.6, the lowest here, and it is the tool people most often switch away from. The free plan covers up to about 500 contacts with limits, Essentials starts at $13 a month, Standard at $20 (500 contacts) is the recommended and most-used paid tier, and Premium runs $350. At scale the bill runs hot: Standard is about $100 a month at 5,000 contacts and paid plans reach about $1,600 at 200,000 before going custom. The real warning is what gets billed. Mailchimp charges on inactive and unsubscribed contacts plus duplicates, layers on overages and paid add-ons, and real spend commonly runs 20 to 40 percent above the list price.
What you get is familiarity: brand recognition, polished UX, a vast template and integration ecosystem, mature analytics, and a tight Intuit and QuickBooks tie-in, and it is the easiest tool to hire for. The ratings are mixed by source. G2 4.3 across about 12,893 reviews and Capterra 4.5 across about 17,565, but Trustpilot is only 2.6 (poor), with about 67 percent one-star driven by billing and account-suspension complaints.
The deeper problem is performance. Mailchimp measures about 87 percent in EmailToolTester testing and is described as sliding, below the 89 percent excellent line. Between declining deliverability, billing on inactive contacts, and the worst value at scale here, most cost-sensitive senders do better elsewhere. It suits very small businesses already in the Intuit ecosystem, or teams that value brand familiarity over price and inboxing.
How to choose
Start with one number: your contact count, or for an infrequently emailed list, your monthly send volume. Then work down the list. If you want the most value with the least friction, pick MailerLite. It wins on price-to-quality and on independently tested inboxing, and it covers the majority of senders. Choose Kit instead only if monetizing a creator audience (paid newsletters, products, recommendations) matters more to you than template design.
Step up to ActiveCampaign when your funnels are genuinely complex and you will use behavioral automation plus a CRM, and you can absorb the cost-at-scale. Pick Brevo when you have a large list you email occasionally, since volume pricing with unlimited contacts can be far cheaper than any per-contact plan, and you want SMS or WhatsApp in the same place. Pick GetResponse when you want email, funnels, and webinars in one tool, just budget for overage fees as your list grows. Default to Mailchimp only if you are already living in Intuit and QuickBooks and value that integration over price and deliverability. As a rule, the cheapest tool that covers your funnels and tests well on inboxing is the right answer, and that is usually not the brand you have heard of most.
FAQ
What is the best email marketing software overall in 2026?
For most senders, MailerLite. It has the best price-to-quality ratio in the category (from $10 a month, roughly $50 to $90 at 10,000 subscribers), one of the highest independently tested inbox rates at about 94.4 percent over EmailToolTester’s last five rounds, and the strongest buyer ratings here (Capterra 4.7). Heavy-automation teams should look at ActiveCampaign, and creators monetizing an audience at Kit.
Why does deliverability matter more than price or features?
Because an email that lands in spam earns nothing, no matter how cheap the plan or how clever the automation. Independent seed tests from EmailToolTester put the all-platform average inbox rate at about 83.1 percent, and Validity’s 2025 benchmark puts the true global average at 83.5 percent. The spread between the best tools (about 94 percent) and the weaker ones (about 87 percent) is the difference in revenue you never see, which is why we rank it first.
Is a vendor’s 99 percent “delivery rate” the same as reaching the inbox?
No. A delivery rate only means the receiving mail server accepted the message, not that it reached the inbox rather than spam. Kit, for example, advertises 99.8 percent delivery and 99.4 percent inbox placement but does not submit to independent seed-based tests, so the figure is not comparable to the ~94 percent inbox rates measured for MailerLite or ActiveCampaign. Trust third-party tests over vendor claims.
Which tool is cheapest for a large list?
Usually Brevo, because it bills on emails sent rather than contacts and offers unlimited contacts. If you have a big list you email only occasionally, volume pricing can be far cheaper than any per-contact plan. The opposite case is Mailchimp, which bills even on inactive and unsubscribed contacts and commonly runs 20 to 40 percent above its list price at scale.
Why does Mailchimp rank last if it is the most popular?
Popularity is not value. Mailchimp is the most expensive option here at scale, it bills on inactive and unsubscribed contacts, its deliverability sits at about 87 percent and is described as sliding (below the 89 percent excellent line), and its Trustpilot score is only 2.6 with about 67 percent one-star reviews over billing and suspensions. Most price- or deliverability-sensitive senders do better elsewhere.
Should I trust Trustpilot or G2 and Capterra reviews more?
Weight G2 and Capterra higher. They verify business buyers and carry large samples (for example, ActiveCampaign has over 14,500 reviews on G2 and Mailchimp over 17,000 on Capterra). Trustpilot skews toward consumers with billing complaints, which is why nearly every brand scores far lower there. Still read recent one-star reviews on any platform, since they reveal the real failure modes: surprise billing, account suspensions, and gated support.
