The demo above drafts a campaign plan, the emails and the ad copy for a small business in about 30 seconds. A marketing automation tool sends the sequence. This is the part that writes it.
The short answer: the best marketing automation software for a small business is usually MailerLite if price matters most, ActiveCampaign if you want deep automation, Mailchimp if the team wants the easiest learning curve, and HubSpot only if you also need a CRM and can afford its $800 Professional tier. At 1,000 contacts, published US prices run from $15 to $59 a month for the email-led platforms. At 5,000 contacts they run from $49 to $179. The software is the smaller cost, though. What most small businesses are short of is the time to plan and write the automations, which is why so many accounts end up sending one newsletter a month from a tool built for much more.
Prices below are the US dollar prices read from each vendor's own pricing page or price file on 17 September 2026. Where a vendor showed us a non-US currency or quoted inside an app, we say so instead of converting.
Marketing automation software for small business, priced
The table compares the platforms small businesses shortlist most often, at the list sizes most of them actually have. Monthly billing unless noted, because that is what you pay while you find out whether the tool fits.
| Platform and plan | 500 contacts | 1,000 contacts | 5,000 contacts | What decides the bill |
|---|---|---|---|---|
| MailerLite Comfort | $12 | $19 | $49 | Subscribers. Power costs $25, $39 and $69 at the same sizes. 10% off annual |
| ActiveCampaign Starter | Billed as 1,000 | $19 | $99 | Contacts. $15 a month at 1,000 billed annually. Capped at 25,000 contacts |
| ActiveCampaign Plus | Billed as 1,000 | $59 | $179 | Contacts. $49 at 1,000 and $145 at 5,000 billed annually |
| Mailchimp Essentials / Standard | $13 / $20 | Rises by band | Rises by band | All contacts, including unsubscribed ones. Premium is $350 with 10,000 contacts |
| Omnisend Standard | $16 | Rises with list | Rises with list | Contacts who receive messages. Unsubscribed contacts are not billed. Pro from $59 |
| GetResponse Starter | Billed as 1,000 | $19 | Rises with list | Subscribers. Starter includes only one automation workflow. 18% off annual |
| HubSpot Marketing Hub Starter | $7 a seat | $7 a seat (1,000 included) | More contacts cost extra | Seats plus marketing contacts. Automation workflows sit on Professional at $800 a month |
Two platforms are missing numbers on purpose. Klaviyo prices its paid tiers through a calculator and its free tier covers 250 profiles and 500 emails a month, so price it at your own list size before comparing. GetResponse showed us euro and zloty prices for its Marketer tier, which is where its automation builder lives, and we do not convert foreign prices into dollars.
Where the automation actually starts on each plan
The entry price and the automation price are often different plans, and that gap is where small-business budgets go wrong. Three cases are worth knowing before you sign up.
HubSpot. Starter costs $7 a seat a month and includes 1,000 marketing contacts, which makes it look like the cheapest option on the list. The multi-step workflows that people buy HubSpot for are on Professional, which is $800 a month with three core seats and 2,000 marketing contacts, plus a one-time $3,000 onboarding fee that HubSpot requires. We walk through that cliff seat by seat in HubSpot pricing in 2026, and HubSpot competitors and alternatives covers the platforms people move to instead.
GetResponse. Starter at $19 a month for 1,000 subscribers includes unlimited sends but only one automation workflow. That is enough for a welcome series and nothing else. Budget for Marketer if you want the quote follow-up and the post-purchase sequence as well.
ActiveCampaign. All four tiers include automation, which is its strength, but the price roughly doubles between list sizes: Plus goes from $59 a month at 1,000 contacts to $179 at 5,000 and $239 at 10,000 on monthly billing. If your list is growing quickly, price it at next year's size. Our ActiveCampaign alternative page has the full ladder and the cheaper builders people switch to.
What 1,000 and 5,000 contacts really cost
Take a local business with one owner and one assistant, a list of 1,000 customers and prospects, and three automations it wants running: a welcome sequence for new subscribers, a follow-up for quotes that go quiet, and a review request after each job. On annual billing, the monthly cost at 1,000 contacts is about $17 on MailerLite Comfort, $15 on ActiveCampaign Starter, $49 on ActiveCampaign Plus and $14 on HubSpot Starter for two seats. Every one of those is cheaper than an hour of anyone's time.
Now grow the list to 5,000. MailerLite Comfort becomes $44 a month billed annually, ActiveCampaign Plus $145, and HubSpot, if you want its automation, is still $800 plus the onboarding fee. The spread at 5,000 contacts is several hundred dollars a month, and it comes entirely from which meter the vendor chose. That is the number to compare, because a list that works tends to grow. The marketing automation cost guide lays out the meters side by side for larger lists.
The three automations that pay back first
Small businesses buy automation software and then build nothing, because the setup is a blank canvas. If you only build three workflows, build these, in this order.
1. The welcome sequence. Three to five emails over two weeks for anyone who joins the list, introducing the business, answering the obvious objections and making one offer. It works while you sleep, and it is the automation every platform above supports on its entry plan.
2. The follow-up nobody sends. For ecommerce that is the abandoned cart email. For a service business it is the quote that went quiet: a reminder at three days, a question at a week, and a last note at two weeks. Most small businesses lose more revenue here than anywhere else, simply because following up by hand is the task that slips.
3. The review request. An email a few days after purchase or completion asking for a review, with a direct link. Reviews feed every other channel, from local search to ads. Most email platforms can send the request, and if you want to gather, approve and publish the responses on your site as well, a tool built to collect and display customer testimonials handles that part better than a newsletter tool.
Whether all this pays for a small business at your size is a fair question, and we run the numbers in is marketing automation worth it for a small business.
Which one to buy
You want the lowest bill
MailerLite Comfort
$19 a month at 1,000 subscribers, automation included, and the gentlest price curve as the list grows.
You will build complex workflows
ActiveCampaign Plus
The deepest automation builder at small-business prices. Price it at the list size you expect next year.
You sell online and want SMS too
Omnisend or Klaviyo
Built around store events such as carts and orders. Omnisend does not bill unsubscribed contacts.
You need a CRM and a sales pipeline
HubSpot
Worth it when the CRM is the reason to buy. Budget $12,600 for year one on Professional, not $7 a seat.
The part none of these tools do
Every platform on this list is a sending engine with a workflow builder. None of them decides what the welcome sequence should say, writes the five emails, plans this month's promotion, or makes the Facebook ad that fills the list in the first place. For a small business without a marketer, that is the real bottleneck, and a cheaper sender does not remove it.
That is the gap we built AiMarketer for. It is an AI marketing agent: you give it the offer and the audience, it plans the campaign, writes the emails, posts and ads, and launches them on your approval, then reports what worked in plain English. It is not an email sender, so most small businesses keep MailerLite, Mailchimp or ActiveCampaign for delivery and let the agent do the planning and writing. The Starter plan is $49 a month for one brand, and Growth at $149 adds launching and budget optimization across every channel, including Facebook ads automation.

Questions small businesses ask about marketing automation
What is the best marketing automation software for small business?
For most small businesses the shortlist is MailerLite for price, ActiveCampaign for automation depth, Mailchimp for ease of use and HubSpot if you also want a CRM. On 17 September 2026 MailerLite Comfort cost $19 a month at 1,000 subscribers and ActiveCampaign Plus $59. Pick on the automation you will actually build, not the feature list.
How much does marketing automation cost for a small business?
Plan on $15 to $60 a month at 1,000 contacts and $50 to $180 at 5,000 contacts for an email-led platform, going by published US prices. HubSpot is the outlier: Starter is $7 a seat, but its automation tier, Professional, is $800 a month plus a one-time $3,000 onboarding fee. The larger hidden cost is the hours spent building the workflows.
What is the cheapest marketing automation software?
On published US prices, MailerLite is the cheapest full automation builder: Comfort is $12 a month at 500 subscribers and $19 at 1,000, with 10 percent off annual billing. ActiveCampaign Starter is $15 a month billed annually at 1,000 contacts, and Omnisend Standard is $16 at 500 contacts. Cheapest at 500 contacts is not always cheapest at 5,000.
Is HubSpot too expensive for a small business?
HubSpot Starter at $7 a seat is not expensive, but it is not where HubSpot's marketing automation lives. The Professional tier that most people mean is $800 a month with three seats and 2,000 marketing contacts, plus a mandatory $3,000 onboarding fee. For a small business that is about $12,600 in year one, so it only pays when the CRM is the real reason to buy.
Do small businesses need marketing automation?
A small business needs it once three emails keep being sent by hand: the welcome sequence, the abandoned cart or quote follow-up, and the post-purchase review request. Those three recover real money with no extra effort after setup. If you do not have a list of at least a few hundred people or any repeat purchase, spend the budget on getting customers first.
Is Mailchimp good for marketing automation?
Mailchimp is good for simple automations and easy to learn, and in the US its Essentials plan starts at $13 a month and Standard at $20 at 500 contacts. It counts unsubscribed contacts toward your bill, so costs rise with list size faster than on some rivals. Teams that outgrow its journeys usually move to ActiveCampaign or Klaviyo.
