Marketing Automation for Small Business: Mailchimp vs ActiveCampaign vs Keap (2026 Pricing)
Mailchimp, ActiveCampaign, Constant Contact, and Keap compared on real 2026 pricing — and what none of them do to get you found or keep reviews coming in.
Short answer: Marketing automation software for small businesses — Mailchimp, ActiveCampaign, Constant Contact, and Keap are the names that come up most — runs from around $12/month at the entry tier to several hundred dollars a month once your contact list and feature needs grow. Each is a genuinely capable email and automation tool. None of them get you found in search, write your content, or manage your reviews — they automate the sending, not the marketing plan behind it.
What does marketing automation software actually do?
It takes a manual task — send this email when someone signs up, tag this contact when they click, follow up a few days after a purchase — and runs it on rules you set once instead of you remembering to do it by hand. For a small business, that mostly means welcome emails, abandoned-cart nudges, and basic lead-nurture sequences.
What do the top marketing automation tools cost in 2026?
Pricing in this category scales with your contact list, which most comparison pages bury. Here's what's actually published, hedged where vendors give ranges rather than fixed numbers:
| Tool | Entry tier (approx.) | Scales to (approx.) | What it's built for |
|---|---|---|---|
| Mailchimp | Essentials starting around $13/mo (500 contacts) | Premium starting around $350/mo (up to 10,000 contacts) | Email marketing with light automation; free plan now capped at 250 contacts / 500 sends |
| ActiveCampaign | Starter starting around $15/mo (1,000 contacts, annual billing) | Enterprise starting around $145/mo (1,000 contacts) — cost multiplies fast as contacts grow | Deeper marketing + sales automation, CRM add-ons |
| Constant Contact | Lite starting around $12/mo (500 contacts) | Premium starting around $80/mo (500 contacts), climbing steeply per contact tier | Straightforward email marketing for small lists |
| Keap | Starting around $249–$299/mo (2 users, ~1,500 contacts) | Higher tiers reported around $399–$599/mo, plus a one-time onboarding fee often $500–$2,999 | CRM + automation bundled together |
A few things worth knowing before you pick one:
- Every one of these prices by contact count, not just features. Doubling your list can more than double the bill — Constant Contact's own tiers show a jump from around $12 to roughly $50/month just for going from 500 to 1,000 contacts on the entry plan.
- ActiveCampaign and Keap both carry meaningful costs beyond the sticker price — ActiveCampaign gates CRM pipelines, SMS, and custom reporting as add-ons; Keap's onboarding fee alone can run into four figures before you send a single email.
- Mailchimp's free plan has gotten smaller, not bigger — cut to 250 contacts and 500 monthly sends as of February 2026, pushing most active small businesses onto a paid tier faster than before.
To be fair to all four: they're not bad tools. Mailchimp is easy to learn, ActiveCampaign's automation logic is genuinely powerful, Constant Contact is simple for a first list, and Keap bundles a CRM in with the automation. The issue isn't quality — it's that all four stop at "send the email," and marketing is a lot more than sending emails.

What's the real cost once you add the rest of the marketing stack?
None of these tools work alone. A small business running real marketing also typically needs something for SEO and getting found in search, and something to manage and request reviews. Layer a $79/month ActiveCampaign plan with a separate SEO tool and a review-management subscription, and a solo marketer is often past $150–$250/month in software before counting the hours spent keeping contact lists and campaigns in sync across each login.
That stacking problem isn't unique to marketing — the same pattern shows up on the sales side, where Apollo, Pipedrive, and HubSpot each solve one piece and leave the owner connecting the rest by hand.
Is marketing automation software enough on its own?
If your only need is "send scheduled emails to a list I already have," yes — pick one above and it'll do that job well for well under $100/month at a small contact count.
But most owners asking about marketing automation don't have one problem. They have a business that isn't showing up when people search for what they do, reviews that trickle in unevenly, and an email list that only gets a campaign when there's spare time — which there rarely is. None of the four tools above touch search visibility or review generation; they send to a list, they don't build one or make sure new customers find you first.
What does StoryDrips do differently?
None of the tools above are really comparable to what we build, and it's worth saying that plainly instead of forcing a false fight. Mailchimp, ActiveCampaign, Constant Contact, and Keap are marketing automation platforms — genuinely good at sequencing and sending email to a list you already have.
StoryDrips is an AI Operating Partner. Instead of logging into a separate automation platform, SEO tool, and review dashboard, you have one conversation where you say what's happening in the business, and it coordinates the specialist engines behind the scenes: Get Found, Convert More, Build Authority, Keep Connected, Run Smarter. Email sequencing is one small piece of Build Authority and Keep Connected — not the whole job. It's built around how you work, not how a software company thinks marketing should be organized into a per-contact bill.
If part of what you need is a well-built automation sequence, one of the tools above may genuinely be enough on its own. The free strategy brief shows what's actually worth fixing first.
FAQ
What's the cheapest marketing automation software for a small business? Constant Contact's Lite plan and Mailchimp's Essentials plan both start around $12–$13/month for a small contact list. Pricing scales quickly with list size on every platform in this category, so the entry price is rarely what you'll pay once your list grows.
Does Keap replace a CRM? Largely, yes — Keap bundles a CRM with its automation tools, which is why it costs more (starting around $249–$299/month) than pure email tools like Mailchimp or Constant Contact. It also carries a mandatory one-time onboarding fee that can run into four figures.
Do I need marketing automation software and something else for SEO or reviews? Yes, if you want to be found in search and keep review flow steady. None of the four tools compared here handle search visibility or review requests — they automate sending to a list you already have, not building the list or the visibility that feeds it.
What's the difference between marketing automation software and an AI Operating Partner? Marketing automation software sequences and sends email to your existing contacts. An AI Operating Partner coordinates the outcome across the business — getting found, converting leads, building authority, and staying in touch — as one conversation instead of a separate login for each piece.
