As a solo entrepreneur, you have limited time. Yet marketing demands consistency: daily social posts, timely email follow‑ups, lead nurturing, and constant testing. Doing all of this manually is impossible – you'd burn out within months. The solution is marketing automation. But traditional automation tools like HubSpot or Marketo cost hundreds per month, and Zapier charges per task.
Open source marketing automation gives you enterprise‑grade capabilities for a fraction of the cost – and without vendor lock‑in. In this guide, you'll learn how to automate your marketing using n8n, Mautic, and other open source tools. No coding required, just a willingness to set up workflows once and let them run forever.
n8n, Mautic, and AgentZero – all pre‑integrated in SolOPENpreneur.
Start automating →When someone fills out a form on your website, you want to respond instantly – but you can't be at your computer 24/7. Automate it. Use Mautic to create a form and embed it on your site. Then build an n8n workflow that triggers whenever a new contact is created in Mautic. The workflow can check the lead's source (e.g., which landing page), add them to a specific Mautic segment, and start a tailored nurture sequence. For high‑value leads (e.g., those who visited your pricing page), the workflow can also send you a Nextcloud Talk notification so you can follow up personally.
This whole process happens in seconds, giving leads a professional, instant experience while you sleep.
Manually posting to LinkedIn, Twitter, Facebook, and Instagram every day is a huge time sink. Use Postiz to schedule posts in batches – set aside one hour per week to write 20‑30 posts, then schedule them across all platforms. For even more automation, use n8n to watch your blog's RSS feed. Every time you publish a new blog post, n8n can automatically extract the title and excerpt, generate a social media caption (using Ollama AI), and queue it in Postiz. You never have to manually promote your content again.
Not all leads are equal. Some are ready to buy now; others need months of nurturing. Use Mautic's lead scoring to assign points based on behavior: +10 for visiting your pricing page, +5 for opening an email, +20 for downloading a case study, -5 for unsubscribing. Then use n8n to monitor Mautic contact scores daily. When a lead crosses a threshold (e.g., 50 points), n8n can send you a Nextcloud Talk message: "Hot lead: John Smith – ready to buy." You can even use AgentZero to draft a personalized outreach email based on the lead's activity history.
Over 70% of online shoppers abandon their carts. Recover those lost sales automatically. Use n8n to listen for WooCommerce's "cart abandoned" webhook (or poll the API). When a cart is abandoned, n8n triggers a Mautic sequence: email 1 after 1 hour ("Forgot something?"), email 2 after 24 hours ("10% off if you complete purchase"), email 3 after 48 hours ("Last chance"). If the customer completes the purchase, n8n removes them from the sequence and sends a thank‑you email instead. This alone can recover 10‑30% of lost revenue.
Finding leads manually is tedious. Use OpenClaw to scrape targeted leads from online directories, LinkedIn, or industry forums. Then feed the scraped data into n8n, which cleans it, checks for duplicates, and creates new contact records in Mautic and ERPNext. Finally, n8n can add these leads to a "prospecting" segment in Mautic, which triggers a cold outreach sequence. You can scale lead generation to hundreds per week without manual effort.
Social proof is essential for conversions. Automate the request process. Use n8n to watch ERPNext for invoices marked "paid." Seven days after payment, n8n triggers a Mautic email asking the customer for a review (with links to Google, Trustpilot, etc.). If they don't leave a review after 14 days, send a second email with a small incentive (discount code). If they do leave a review, n8n can capture it and store it in a Nextcloud file for later use on your website. This builds social proof automatically.
If you host webinars or live events, automate the follow‑up sequence. Use Mautic to register attendees. After the event, use n8n to send a thank‑you email, a link to the recording (stored in Nextcloud), and a survey. Based on survey responses (e.g., "interested in purchasing"), n8n can add attendees to different Mautic segments – hot leads go to a sales sequence, cold leads go to a long‑term nurture track. This ensures no lead falls through the cracks.
Creating content is time‑consuming. Get more mileage from each piece. Use n8n to watch for new blog posts in WordPress. When a post is published, n8n sends the content to Ollama with a prompt: "Summarize this blog post into 3 social media captions (one for LinkedIn, one for Twitter, one for Facebook)." Ollama returns the captions, and n8n automatically queues them in Postiz. You can also generate an email newsletter snippet and send it via Mautic. One blog post becomes 5+ pieces of content automatically.
Chasing late payments is awkward and time‑consuming. Automate it. Use n8n to check ERPNext daily for overdue invoices. For invoices overdue by 7 days, n8n sends a friendly reminder via Mautic. For invoices overdue by 14 days, send a firmer reminder. For invoices overdue by 30 days, n8n can create a task for you (or a collections agency) in ERPNext. This ensures you get paid without awkward conversations.
First impressions matter. Automate your client onboarding. When a new client signs a contract in Documenso, n8n triggers a workflow that: creates a customer record in ERPNext, generates a welcome email in Mautic, creates a shared Nextcloud folder for the client, adds the client to a Nextcloud Talk channel, and schedules a kickoff call on your calendar. The client feels taken care of, and you've done zero manual work.
