Best Email Marketing Automation Tools in 2026

Every tool here does roughly the same thing: send email to a list on a schedule or a trigger you define, with forms, segments and reporting around it. They differ less on features than the marketing suggests and more on what happens to the price as your list grows.

Prices were checked against each vendor’s own page on August 8, 2026.

Key takeaways

• The headline price is set by a contact tier, so “from $15” describes a small list and tells you almost nothing about your bill.
• Most of these pages open on a discounted view. Brevo defaults to yearly at 10% off, GetResponse to yearly at 18% off, Omnisend to a 30% three-month prepay, and Mailchimp quotes a rate that holds “for 12 months.” ActiveCampaign publishes annual rates with no monthly toggle at all.
• Free tiers are real at Brevo, Omnisend, Mailchimp and Klaviyo, and they are how most small teams should start.
• Ecommerce is a genuine dividing line. Klaviyo and Omnisend are built around a store; the others are general purpose.
• The gap between tiers is steep. Brevo’s paid pricing jumps straight from $18 to $499, and Mailchimp’s from $20 to $350, with nothing in between.

What determines your bill

Worth doing before you compare anything: find your contact count and your monthly send volume.

Every platform here charges on one or both. A plan quoted at $15 assumes a list in the hundreds or low thousands. Add contacts and the same plan reprices, often steeply, and the tier names stay the same, so it is easy to believe you are comparing like with like when you are not.

The second thing to check is which view the page loaded in. Brevo opens on “Yearly (-10%)”. Omnisend shows prices with a 30% discount already applied. Mailchimp’s rate is “per month for 12 months,” which is an introductory period rather than the standing price. Only one of the six shows you an undiscounted monthly rate by default.

1. ActiveCampaign

The most automation-oriented of the general-purpose tools, with branching sequences, conditional logic and a CRM alongside the email.

At 1,000 contacts, Starter is $15 a month, Plus $49, Pro $79 and Enterprise $145. Those are annual-billing rates, which is the only basis the pricing page shows; there is no monthly toggle, so the monthly figure appears at checkout. Contact limits and user seats rise through the tiers: one user on Starter and Plus, three on Pro, five on Enterprise.

Best for teams whose sequences have real branching in them, and who want contact records attached.

2. Klaviyo

Built for ecommerce, with deep Shopify and store-data integration. Segments are based on purchase behavior rather than only on email engagement, which is the whole reason to pick it.

The free tier covers 250 profiles. Paid pricing runs on a slider keyed to profile count: $20 a month at 500 profiles, $45 at 1,500. Worth knowing that the slider loads at 1,500 rather than at its minimum, so $45 is the number most people see first and the entry price is less than half that. Email and SMS are priced together.

Best for online stores where what someone bought should decide what they receive.

3. Mailchimp

The default that most people have already used. Broad template library, the gentlest learning curve, and the widest integration coverage of anything here.

At 0 to 500 contacts, Standard is $20 a month and Premium $350. Note the phrasing on their page: those are rates “per month for 12 months,” so check what happens in month 13. A separate offer takes 15% off at 10,000-plus contacts, which is a different tier of the slider and not a discount on the $20.

Best for small teams who want something familiar that works, and are not running complex automation.

4. Brevo

The best free tier of the group and the widest channel spread: email, SMS and WhatsApp in one place, with a CRM attached.

Free forever with no card. Starter is $9 a month, or $8.08 billed yearly. Standard is $18, or $16.17 yearly. Then Professional jumps to $499, or $449.08 yearly, which is a very large step and worth planning around.

Best for budget-conscious teams who want more than email, provided the Standard tier covers you.

5. GetResponse

Email marketing with landing pages, webinars and funnels bundled in, which is unusual and genuinely useful if you run webinars.

At 1,000 contacts, Starter is $19 a month, Marketer $59 and Creator $69, with Enterprise quoted on request. The page loads on “Yearly -18%,” where the same three read $15.58, $48.38 and $56.58, so the figure you land on is the discounted one.

Best for teams running webinars or course funnels who would otherwise buy a second tool for it.

6. Omnisend

Ecommerce-focused like Klaviyo, aimed at smaller stores, with email and SMS in one workflow.

There is a free tier. At 251 to 500 contacts, Standard is $16 a month and Pro $59. The page loads with “Pay 3 months upfront (save 30%)” already switched on, which shows $11.20 and $41.30 instead, and the toggle’s own small print says billing reverts to monthly after three months. SMS is charged separately, starting around $0.007 a message, with credit bundles from $50.

Best for smaller stores that want ecommerce automation without Klaviyo’s price curve.

How to choose

Do you sell products online? If yes, look at Klaviyo or Omnisend first, and treat the others as general-purpose fallbacks. Purchase-behavior segmentation is the thing the general tools do worst.

How big is the list, and how fast is it growing? Price the tier you will be on in a year, not the one you are on today. The steep steps, Brevo’s $18 to $499 and Mailchimp’s $20 to $350, are where budgets break.

How complex are the sequences? If they are broadly linear, almost anything here works, and Mailchimp gets you sending fastest. If they branch on conditions, ActiveCampaign earns its price.

Start free where you can. Brevo, Omnisend, Mailchimp and Klaviyo all have free tiers that are enough to learn whether the tool fits before the list grows into a paid one.

Four things people expect from this category and do not get

These tools send email you decide to send. They do not act on email you receive, and a lot of what people arrive here hoping to automate turns out to be the second kind.

We build this+that for that second kind, so treat the rest of this section as our own account of where the line falls.

Answering a question that needs company knowledge. A quote request arrives at your sales address. A campaign tool has nothing to say about it. A this+that workflow can trigger on the message, look the numbers up in a price sheet held in the brain, draft the reply, and update the task tracking it, with an approval step before anything sends. The general shape is worth more than the example: any inbound message where the right response depends on something your company knows.

Making sure nothing inbound is dropped. Sequences fire on schedules and form submissions. Nobody is watching whether the enquiry that arrived on Friday afternoon got an answer. Assigning the message to a person, tracking that it is open and escalating if it is not is a different mechanism, closer to lead routing, which is one of the things we built, than to a campaign.

Following up on what was actually said. After a call, the follow-up that matters is specific to that conversation rather than to a segment. Same for a renewal that turns on which terms this customer has.

Keeping the list accurate enough for the segments to work. This one is upstream of everything above. Segmentation is only as good as the contact data, and B2B data decays about 2.1% a month, or 22.5% a year. No campaign tool fixes that, because the corrections arrive as signatures, bounces and out-of-office replies in your inbox rather than as list uploads.

The boundary runs the other way too. this+that does not send campaigns, manage subscriber lists or handle bulk deliverability, so if that is what you need, buy one of the six above. Our email workflow automation roundup covers the message-triggered side, us included.

Frequently asked questions

What is the best email marketing automation tool?

For online stores, Klaviyo or Omnisend, because they segment on purchase behavior. For general use, Mailchimp is the easiest to get running and ActiveCampaign the strongest at branching automation.

What do these tools actually cost?

More than the headline, usually. Every plan is tied to a contact tier, so the quoted figure describes a small list. Entry rates as of August 8, 2026 are $15 a month for ActiveCampaign at 1,000 contacts on annual billing, $20 for Klaviyo at 500 profiles, $20 for Mailchimp Standard at 500 contacts, $9 for Brevo Starter, $19 for GetResponse at 1,000 contacts billed monthly, and $16 for Omnisend Standard at 500 contacts.

Which has the best free plan?

Brevo, which is free forever with no card and includes SMS and WhatsApp alongside email. Omnisend, Mailchimp and Klaviyo also have free tiers.

Why do published prices differ from what I see quoted elsewhere?

Because most of these pages load on a discounted view. Brevo defaults to yearly at 10% off, GetResponse to yearly at 18% off, Omnisend to a three-month prepay at 30% off, and Mailchimp’s quoted rate runs “per month for 12 months.” Klaviyo’s slider opens at 1,500 profiles rather than at its minimum. Always move the toggle and the slider before comparing anything.

Do any of these automate replies to incoming email?

No. They send campaigns and triggered sequences you have defined. Acting on messages that arrive is a different category, covered in our email workflow automation roundup.
