Email marketing software stores your contact list, builds and sends campaigns, runs automated sequences like welcome and re-engagement flows, and reports on opens, clicks, and revenue. In 2026 the category has split into three different products sold under one name: general senders like Mailchimp and Brevo, ecommerce lifecycle platforms like Klaviyo and Omnisend, and creator newsletter tools like Kit and Flodesk. They differ most in what they bill you for, which is contacts on some, emails sent on others, and active profiles on the rest. All of them assume you already wrote the email. AutoMarketer is an AI marketing platform that drafts the campaigns you then send from your own tool, with email included on the Growth plan at $149 a month flat.
What you get
The campaign is written, not just scheduled
Every other tool in this category hands you an empty template. AutoMarketer reads your website, builds a brand profile, and drafts the campaign copy and subject lines before you open the editor.
Sequences drafted end to end
Welcome flows, nurture series, and re-engagement emails arrive already written and sequenced, so a new subscriber gets a real onboarding instead of silence until you find a spare afternoon.
Flat pricing, no contact ladder
Most email marketing software raises your bill every time your list grows, which quietly penalizes the thing you are trying to do. AutoMarketer plans are flat, so growing from 1,000 to 10,000 contacts does not change the invoice.
Email that matches your other channels
The newsletter is drafted around what your blog and ads are already saying, because one brand profile feeds all of it. No more email that reads like a different company wrote it.
A calendar instead of a blank editor
You open the tool to a proposed send schedule with the assets drafted against it, rather than a dashboard asking what you would like to create today.
Review first, automate later
Everything waits for your approval in co-pilot mode. Once a flow earns your trust, move it to autopilot and stop looking at it.
How it works
Paste your website URL
The AI reads your site and builds a brand profile in about 30 seconds: what you sell, who buys it, how you sound, and the topics your emails should cover.
Review the proposed plan
You see a campaign calendar and the automated sequences it recommends, with sample assets drafted, free and before you create an account.
Turn email on
Email campaigns and sequences run on the Growth plan and up. Approve each send in co-pilot mode, or promote a flow to full autopilot.
Add the rest of the channels
Switch on SEO, social, and ads so the email is not working alone. The same brand profile keeps every channel telling one story.
Who it is for
The newsletter that keeps slipping
You know the list should hear from you monthly. It does not, because writing each one from scratch is the step that never gets scheduled.
Subscribers who hear nothing after signup
People join your list and then wait weeks for whatever you send next, when a welcome sequence should be doing that work automatically.
Small businesses without a marketer
Owners and small teams who need consistent email but cannot justify a hire or an agency retainer to produce it.
Ecommerce and DTC stores
Stores that need steady promotional and lifecycle email running alongside social and paid, without a dedicated email person.

Email marketing software is really three different products
Search for email marketing software and you get a list that puts Mailchimp, Klaviyo, and Kit side by side as if they compete. They mostly do not. The category has split into three groups that solve different problems, and buying from the wrong group is the most common and most expensive mistake in this purchase.
General senders (Mailchimp, Brevo, MailerLite, Constant Contact) are the default. They hold a list, build a campaign, fire basic automations, and report opens and clicks. They suit a business that emails customers and prospects on a regular rhythm.
Ecommerce lifecycle platforms (Klaviyo, Omnisend) are built around a store. They read order history, tie revenue to individual sends, and run abandoned cart and post-purchase flows off product data. If you run a Shopify or WooCommerce store, the revenue attribution alone usually justifies the higher price. If you do not sell online, most of what you are paying for sits idle.
Creator newsletter tools (Kit, Flodesk, beehiiv) optimize for a person publishing to an audience: landing pages, paid subscriptions, referral mechanics, and clean design. They are a poor fit for a business running segmented campaigns against a CRM.
What your bill actually depends on is the billing unit
Two platforms can advertise similar entry prices and still bill you very differently at scale, because they do not count the same thing. This is the single most useful thing to check before you commit.
Mailchimp, Omnisend, and Constant Contact bill on contacts, so every address you keep costs money whether or not you email it. Brevo bills on emails sent and lets you store unlimited contacts, which is dramatically cheaper for a large, rarely mailed list and more expensive for a small list you mail daily. Klaviyo bills on active profiles, which includes profiles created by your store rather than only people who subscribed. Kit, MailerLite, and Flodesk bill on subscribers.
The practical effect: a nonprofit with 40,000 contacts it mails four times a year and an ecommerce brand with 4,000 contacts it mails four times a week will get completely inverted quotes from the same shortlist. Work out your own contact count and monthly send volume first, then price the shortlist against both numbers. We ran that math across nine platforms in the full email marketing software cost breakdown.
Four of the major platforms repriced in the last twelve months
This category has been unusually unstable, and a lot of the comparison content ranking today is quietly out of date. Kit raised prices across all paid plans in September 2025. Flodesk retired the flat unlimited plan it was famous for on 2 December 2025 and moved to subscriber-based Flodesk pricing tiers. MailerLite replaced its Growing Business and Advanced plans with Comfort and Power. Omnisend stopped bundling SMS credits into subscriptions in May 2026, so SMS is now a separate volume-billed add-on.
If a roundup still quotes a $38 flat Flodesk plan or a $9 MailerLite Growing Business tier, it was not checked recently. Price everything against the vendor page on the day you buy.
The part every one of these tools leaves to you
Here is what none of the comparison tables show. Every platform above automates delivery. Not one of them writes the email. You still open a blank draft, decide the angle, write the subject line, write the body, pick the offer, and do it again next week.
That is why so many small businesses own perfectly good email marketing software and still send four times a year. The blocker was never the send button or the segmentation builder. It was the blank draft on a Tuesday when three other things were on fire. Automating the easy 20 percent of the job and handing back the hard 80 is not the time saving the category advertises.
How AutoMarketer approaches it differently
AutoMarketer starts one step earlier. You paste your website URL, the AI reads it and builds a brand profile covering your product, your audience, and your tone, and then it drafts the actual emails: the campaign for next week, the welcome sequence for new subscribers, the re-engagement email for the people who have gone quiet. You get a calendar with assets attached instead of an empty editor.
Because the same brand profile also drives your social posts, your SEO content, and your ads, the email stops contradicting the rest of your marketing. The campaign your newsletter announces is the campaign your blog supports and your ads amplify. That coordination is the actual argument for running one platform across every channel instead of a separate subscription per channel.
Pricing is flat per plan rather than per contact. Email campaigns and sequences are included on the Growth plan at $149 a month, or $119 a month billed yearly, and stay included as your list grows. If you want the mechanics of triggered sequences specifically, the email marketing automation software page goes deeper on flows, and AI email marketing covers how the drafting works.
When a dedicated email platform is still the better buy
Worth saying plainly, because the honest answer is not always us. If you already have someone who writes your emails and enjoys it, you do not need software that drafts them, and Brevo or MailerLite will cost you less. If you run a serious ecommerce operation and need revenue attributed to individual sends and flows built on product data, Klaviyo does that better than we do and it is not close. If your entire business is a paid newsletter, Kit is purpose-built for it. If you need a 900-template gallery, granular list hygiene tooling, or a dedicated deliverability team on the phone, buy the specialist.
AutoMarketer is the right call when the emails do not get written, when you want lifecycle sequences drafted rather than diagrammed, when a per-contact bill that grows with your list is the wrong incentive, and when you would rather run email as one part of a coordinated plan than as one more tool to feed. Start by running your URL through the demo and reading the email plan it proposes before you decide anything.
Frequently asked questions
What is email marketing software?
Email marketing software stores your contact list, builds and sends campaigns, runs automated sequences such as welcome and re-engagement flows, and reports on opens, clicks, and revenue. It handles permission, unsubscribes, and deliverability so your mail reaches the inbox. Almost every tool in the category automates the sending but still expects you to write each email yourself.
What is the best email marketing software for small business?
It depends on which part is hard for you. If you have someone who writes the emails, MailerLite and Brevo give you the most sending for the money. If you sell online, Klaviyo or Omnisend earn their higher price through revenue attribution. If the emails never actually get written, an AI platform like AutoMarketer is the better fit because it drafts the campaigns rather than only scheduling them.
How much does email marketing software cost?
Entry plans run roughly $9 to $30 a month at 1,000 contacts in August 2026, and most platforms raise that as your list grows. Brevo starts at $9, MailerLite at $12, Constant Contact at $12, Klaviyo at about $30, and Kit at $39. Flat-plan marketing platforms that also write the content start higher, at $149 a month, and do not scale with list size.
What is the difference between an email marketing platform and an email marketing service?
In practice the terms are used interchangeably by vendors and buyers alike. Where a distinction is drawn, service tends to describe the sending infrastructure and deliverability layer, while platform implies broader functionality such as automation, landing pages, segmentation, and reporting. Judge tools by the features and the billing unit rather than by which word appears in the marketing.
Is free email marketing software good enough?
Free tiers work for a first list and genuinely low volume. Mailchimp gives you 250 contacts, Brevo allows 300 emails a day with unlimited contacts, and Kit is free to 10,000 subscribers. They stop being viable once you need automation depth, branding removal, or send volume, and the jump to paid is usually where the real comparison starts. Pick on what the paid tier costs, not the free one.
Do I need email marketing software if I already have a CRM?
Usually yes, unless your CRM includes a real marketing email module. A CRM tracks relationships and deals; email marketing software handles bulk sending, consent, unsubscribe management, and deliverability reputation. Sending campaigns from a normal inbox or a CRM that is not built for it damages your domain reputation and gets you filtered into spam.
What email marketing software works with Shopify?
Klaviyo and Omnisend integrate most deeply with Shopify because they read order and product data directly, which is what makes abandoned cart and post-purchase flows work. Mailchimp and Brevo also connect but with less commerce depth. AutoMarketer runs email alongside SEO, social, and ads for a store, which suits merchants who need the whole marketing handled rather than store-specific flows alone.
