These four tools are often compared because they all sit at the intersection of CRM and marketing automation. But they're not really competing for the same customer. HubSpot is building toward enterprise. ActiveCampaign is optimized for email automation depth. Keap is a full business management platform for service companies. Ontraport is aimed squarely at solopreneurs and small teams selling online. Here's the breakdown.
Quick comparison
| Feature | HubSpot | ActiveCampaign | Keap | Ontraport |
|---|---|---|---|---|

| Free plan | Yes (CRM + basic email) | 14-day trial only | No | No |
| CRM depth | Strong — full pipeline, deals, tasks | Moderate — deal tracking, pipelines | Strong — built for service business sales | Moderate — contact-centric |

| Best for | Teams wanting free CRM that scales | Businesses that live and die by email automation | Service businesses: contractors, consultants | Coaches, course creators, membership sites |
HubSpot
HubSpot built its reputation on the free CRM tier. You get contact management, deal pipelines, task tracking, email templates, and a basic form builder at no cost. That free tier is genuinely useful for early-stage businesses, and it's why HubSpot is often the default recommendation for anyone who asks "what CRM should I use?" According to HubSpot's 2024 annual report, the company serves more than 230,000 customers across 135+ countries.
The catch is that the features you actually want for marketing automation — behavioral email sequences, A/B testing, advanced workflows, and custom reporting — live on paid plans that add up fast. Marketing Hub Starter is around $20/month but still relatively limited on automation. Marketing Hub Professional jumps to $890/month for the features that compete head-to-head with ActiveCampaign. That pricing jump is the main reason businesses look at alternatives when they outgrow the free tier.
Where HubSpot genuinely wins: if you have a sales team. The CRM pipeline management, call logging, meeting scheduling, and deal tracking are better than what you get from ActiveCampaign, Keap, or Ontraport. If your primary need is managing a B2B sales process with email marketing running alongside it, HubSpot is the strongest option here.
- Free CRM is genuinely useful, not a stripped-down teaser
- Best sales pipeline and deal management in this group
- Marketing automation gets expensive quickly on paid tiers
- Integrates with nearly everything via native connections and HubSpot's app marketplace
- Steeper learning curve on paid tiers — takes time to configure properly
ActiveCampaign
ActiveCampaign's automation builder is the most flexible in this comparison. You can trigger sequences based on email opens, link clicks, site visits, purchase history, custom fields, or any combination of those. The if/then branching, goal conditions, and lead scoring tools let you build sequences that genuinely respond to what a contact does, not just when they joined your list. ActiveCampaign reports more than 180,000 customers across 170+ countries.
The Starter plan at ~$15/month includes email marketing and basic automation for up to 1,000 contacts. The Plus plan (~$49/month) adds CRM features, custom audiences, and deeper integrations. Most serious users end up on Plus or Professional. Even at those tiers, it's significantly cheaper than HubSpot Professional for comparable automation depth.
The CRM side is functional but not deep. Deal pipelines exist and work, but if your primary use case is managing a B2B sales process, you'll find HubSpot or Keap more suited to that workflow. Where ActiveCampaign wins is when your marketing automation is sophisticated and your CRM needs are simpler — solo operators, small teams, e-commerce businesses, and service businesses that run on email sequences rather than sales reps.
- Best email automation depth in this group — behavioral triggers, lead scoring, complex branching
- Competitive pricing vs. HubSpot for comparable automation features
- CRM is functional but not as strong as HubSpot or Keap for pipeline management
- No built-in invoicing or payment collection
- Site tracking and attribution reporting require additional setup
Keap
Keap rebranded from Infusionsoft in 2019 to signal a simpler, more approachable product. The rebrand helped, but Keap is still a serious tool for serious businesses — not a lightweight starter option. The starting price of around $299/month reflects that. For that price, you get CRM, email and SMS marketing automation, invoice and quote generation, appointment booking, and a pipeline management tool.
The use case Keap is built for: a service business (contractor, consultant, health practitioner, agency) that wants to manage leads from inquiry through signed contract and invoice without stitching together five different tools. The automation handles follow-up sequences when someone fills out a form, the CRM tracks where they are in the sales process, and the invoicing tool handles billing after the deal is done. It's not elegant, but it covers a lot of ground in one place.
The main complaints about Keap are cost and complexity. $299/month is a commitment. The interface has improved but still requires real setup time before it does anything useful. If you just need email marketing and can handle billing separately, you're paying for features you won't use. Keap earns its price for businesses that actually need all of it.
- Built-in invoicing and payment collection — cuts out a separate billing tool
- Strong CRM for service business sales pipelines
- Email and SMS automation in one platform
- Appointment booking and intake forms included
- Expensive relative to the other three — price is justified only if you use most of it
- Setup complexity is real — expect a learning period
Ontraport
Ontraport occupies a specific niche: online business owners who need a full marketing stack (CRM, email, landing pages, payments, affiliate management) without enterprise pricing. The basic plan starts at $24/month for up to 500 contacts, which is significantly more accessible than Keap. As your contact list grows, pricing scales — at 10,000 contacts, it's around $157/month.
The built-in affiliate management system is Ontraport's clearest differentiator. If you sell a course, coaching program, or digital product and want to run an affiliate program without a third-party tool, Ontraport handles it natively. HubSpot, ActiveCampaign, and Keap don't. That feature alone is why some digital product sellers stick with Ontraport even though they could find cheaper options for pure email marketing.
The platform's page builder is functional and handles landing pages, sales pages, and checkout flows in one tool. The visual campaign builder is similar to ActiveCampaign's but slightly less flexible on complex behavioral triggers. For most coaches and course creators, it's more than enough. Where Ontraport falls short: it's not well-suited for businesses with offline sales processes, field service teams, or complex B2B pipelines. It's built for digital-first businesses.
- Built-in affiliate management — unique in this group
- Native landing pages, checkout, and payment processing
- CRM handles contact management and basic pipeline
- More affordable entry point than Keap
- Less automation depth than ActiveCampaign on complex behavioral triggers
- Less well-known brand — fewer native integrations than HubSpot
Which one to pick
Start free, add marketing features as you scale. Best if you have or plan to have a sales team.
Best behavioral automation, lead scoring, and sequence logic at a reasonable price point.
CRM + automation + invoicing in one place. Worth the price if you actually need all of it.
Built-in affiliates, landing pages, and checkout. The platform online business owners stick with.
You have a sales team managing a pipeline. You want to start free and add features over time. CRM is more important than email automation depth.
Email automation is your primary growth engine. You want behavioral triggers, complex if/then sequences, and lead scoring without paying HubSpot's top-tier prices.
You run a service business and want CRM, follow-up automation, and invoicing without managing separate tools. The $299/month is justified when you're using all of it.
You sell courses, coaching, or digital products and need native affiliate management. The all-in-one platform for digital-first online businesses.
The automation layer none of them fully provide
All four tools handle their own internal automation well. What they don't do is automatically connect to the rest of your business stack.
A new contact in HubSpot doesn't automatically kick off your onboarding process in your project management tool. A deal marked "Won" in ActiveCampaign doesn't automatically create the invoice in QuickBooks. A new Ontraport purchase doesn't automatically grant access to your course platform and send a Slack notification to your fulfillment team. Each of those connections has to be built separately.
That's where tools like n8n, Make, or Zapier come in — and where businesses either build those connections themselves or hire someone to build them. The time you spend manually copying data between systems is almost always the first thing to automate once you've picked your primary CRM and email platform.

Frequently asked questions
HubSpot is better if you want a full CRM with a free starting tier and plan to grow into sales pipeline management. ActiveCampaign is better if email automation depth is the priority — behavioral triggers, complex if/then sequences, and lead scoring at a lower price than HubSpot's paid tiers. For most small businesses focused on marketing automation over sales team management, ActiveCampaign gives more per dollar.
Keap is a CRM and marketing automation platform built for service-based small businesses. It handles contact management, automated follow-up sequences, invoicing, appointment booking, and lead capture in one tool. It starts around $299/month — higher than the other three — but covers more of the sales and billing workflow for service businesses like contractors, consultants, and home services companies.
Ontraport is best for coaches, course creators, consultants, and membership site owners who need CRM, email marketing, landing pages, and built-in affiliate management in one platform. The native affiliate management is the main differentiator — none of the other three tools in this comparison have it. Starting at $24/month for up to 500 contacts, it's more affordable than Keap at a comparable all-in-one feature set.
Both are all-in-one CRM and marketing automation platforms for small business. Keap is better for service businesses with offline sales — strong invoicing, appointment booking, and pipeline management. Ontraport is stronger for digital product sellers: native affiliate management, membership site tools, and a built-in page builder. Keap starts around $299/month; Ontraport starts at $24/month. Both have steeper learning curves than simpler tools like Mailchimp.
ActiveCampaign has CRM features — deal pipelines, contact records, task management — but it is primarily a marketing automation platform, not a full CRM. The CRM is solid for small teams managing a simple sales pipeline, but it is not as deep as HubSpot's or Keap's. If CRM pipeline management is your primary need, HubSpot or Keap is a stronger fit. If email automation is primary with light CRM needs, ActiveCampaign works well.
