Marketing automation software is expensive. HubSpot Marketing Hub starts at $800/month. Marketo costs even more. Pardot, Eloqua, ActiveCampaign — they all add up fast.
But here's the thing: most of what those tools do is just workflow automation with a marketing UI on top.
You can build the same functionality yourself for a fraction of the cost. Here's how.
What "Marketing Automation" Actually Is
Strip away the marketing buzzwords, and you have:
- Triggers: Something happens (form submitted, email opened, page visited)
- Logic: Decide what to do (if lead score > 50, send this email)
- Actions: Do the thing (send email, update CRM, add to list)
That's just automation. The "marketing" part is which triggers, logic, and actions you use.
The Affordable Stack
Here's a stack that costs under $100/month for most small businesses:
Email Sending
- ConvertKit ($29/mo) or Buttondown ($9/mo) for newsletters
- Postmark or SendGrid for transactional emails (cheap at low volumes)
Data Storage
- Airtable (free tier) or Google Sheets for simple databases
- Supabase (free tier) for more complex needs
Automation Engine
- n8n (self-hosted = free) or Make.com ($9/mo)
- This is where the magic happens
Form Capture
- Tally (free) or Typeform ($25/mo)
Website Analytics
- Plausible ($9/mo) or Fathom ($14/mo)
Total: ~$50-80/month vs. $800+/month for HubSpot Marketing Hub
The Workflows You Can Build
Let's get specific. Here are marketing automations you can build with this stack:
1. Lead Capture and Nurture Sequence
Trigger: Someone fills out your lead magnet form
Workflow:
- Add to email list with tag "lead-magnet-xyz"
- Send immediate delivery email
- Wait 1 day
- Send nurture email #1
- Wait 2 days
- Send nurture email #2
- Continue sequence based on engagement
Tools: Tally (form) → n8n (automation) → ConvertKit (email)
2. Lead Scoring
Trigger: Various events happen
Scoring logic:
- Downloaded resource: +10 points
- Visited pricing page: +15 points
- Opened 3+ emails: +10 points
- Company size > 50: +20 points
- Clicked demo request: +30 points
When score > 50: Alert sales or send high-intent sequence
Tools: n8n (scoring logic, stored in Airtable) → Slack (alerts)
3. Abandoned Cart Recovery
Trigger: User has items in cart but hasn't checked out in 2 hours
Workflow:
- Wait 2 hours
- Check if purchase completed
- If not, send reminder email #1
- Wait 24 hours
- Check again, if still abandoned, send email #2 with discount
- Wait 48 hours
- Final reminder email #3
Tools: Your e-commerce platform webhook → n8n → email service
4. Webinar Registration Flow
Trigger: Someone registers for webinar
Workflow:
- Add to webinar attendee list
- Send confirmation with calendar invite
- 24 hours before: Send reminder
- 1 hour before: Send "starting soon" with link
- After webinar: Send recording to no-shows
- 2 days after: Send follow-up resources
Tools: Tally (registration) → n8n → ConvertKit + Google Calendar
5. Content Upgrade Delivery
Trigger: Reader requests content upgrade via embedded form
Workflow:
- Verify email isn't disposable
- Send PDF via email
- Tag contact with content interest
- Add to relevant nurture sequence
- Track which content upgrades convert best
Tools: Tally embedded form → n8n → email service + tracking spreadsheet
6. Social Proof Automation
Trigger: Customer leaves positive review or testimonial
Workflow:
- Store testimonial in database
- Format for different platforms
- Post to social channels (with permission)
- Add to website testimonial rotation
- Send thank you note with referral request
Tools: Form/review platform → n8n → social APIs + Airtable
The Patterns That Transfer
Notice the patterns across these workflows:
Timing-Based Sequences
"Send this, wait, send that" — most nurture campaigns follow this pattern.
Conditional Branching
"If X, do this. Otherwise, do that." — personalization at scale.
Data Enrichment
"Before taking action, gather more information." — better targeting.
Multi-Channel Orchestration
"Trigger across email, social, CRM simultaneously." — integrated campaigns.
Learn these patterns, and you can build any marketing automation.
When Enterprise Tools Make Sense
To be fair, here's when the expensive tools actually justify their cost:
Massive Scale
If you're sending millions of emails, the math changes.
Complex Attribution
Multi-touch attribution across many channels is hard to DIY.
Team Collaboration
When 20 marketers need to build and manage workflows, enterprise UX helps.
Compliance Requirements
Some industries need enterprise-grade compliance features.
If none of these apply, you probably don't need the enterprise price tag.
Getting Started
Here's the practical path:
Week 1: Set Up Your Stack
- Create accounts for email service, form tool, automation tool
- Connect them together
- Test a simple "form → email" workflow
Week 2: Build Your First Sequence
- Lead magnet delivery + nurture sequence
- This alone saves hours per week
Week 3: Add Scoring
- Track engagement across touchpoints
- Identify high-intent leads automatically
Week 4: Expand
- Add more sequences
- Build more complex logic
- Integrate more tools as needed
You'll have marketing automation comparable to enterprise tools within a month.
The Mindset Shift
Enterprise marketing automation vendors want you to believe you need their specific features.
The reality: you need automation capabilities, not marketing software specifically.
When you understand automation as a skill, you can build anything. Marketing automation is just automation applied to marketing problems.
