Mautic open-source marketing automation: email campaigns, lead scoring, and workflows. Self-hosted on Liquid Web VPS — includes 2026 funding-status disclosure.
Mautic and Listmonk are the two most common self-hosted answers to Mailchimp and HubSpot email — but they solve different problems. Listmonk is a high-performance newsletter sender. Mautic is a full marketing automation platform with drip campaigns, lead scoring, landing pages, and CRM-lite features. Picking the wrong one means either paying for complexity you don't need or hitting a ceiling on automation you can't reach.
Mailchimp Essentials charges $20/month for 500 contacts and 6,000 sends. Self-hosting removes both caps: a Liquid Web 2–4 GB Managed VPS running Listmonk can send to an unlimited subscriber list at the cost of your SMTP relay — typically $1–3 per 10,000 emails via Postmark or Mailgun.
Measured idle RAM: ~3.0 GB; peak: ~4.5 GB on a 16 GB VPS
Minimum Liquid Web tier: 16 GB Managed VPS (~$30/mo)
HubSpot Marketing Hub Pro + CRM + Service Hub Pro: $800–$1,340+/mo; this stack: ~$30/mo
HubSpot charges separately for CRM, marketing automation, and customer support — and the Professional tier alone runs $800/mo before seat costs. This guide deploys all three functions with open-source equivalents: Twenty CRM for pipeline management, Mautic for email marketing and lead scoring, and Chatwoot for multi-channel support — on a single Liquid Web 16 GB VPS using one Compose file.
Minimum Liquid Web tier: 8 GB Managed VPS (~$33–$40/mo)
Shopify Basic ($79/mo) + Klaviyo ($45/mo) + Gorgias ($10/mo) = $134/mo plus transaction fees; this stack: ~$33/mo with 0% transaction fees
Shopify bundles storefront hosting, payment processing, and a basic admin — but the moment you add email automation (Klaviyo) and customer support (Gorgias), costs compound fast. This guide deploys the open-source equivalents: Medusa.js for headless commerce, Mautic for email and marketing automation, and Chatwoot for multi-channel customer support — on a single Liquid Web 8 GB VPS, wired together so new orders automatically flow into Mautic campaigns and Chatwoot agents can look up order history without leaving the conversation.
Minimum Liquid Web tier: 8 GB Managed VPS (~$30–$40/mo)
GA4 (free) + Typeform ($50/mo) + ActiveCampaign ($49/mo) = $99/mo; this stack: ~$30/mo on your own server
Most SaaS teams have three separate tools that should talk to each other but don't: an analytics platform, a user feedback tool, and an email automation platform. The data lives in three silos. You see a traffic spike in GA4, you have NPS responses in Typeform, and you have email segments in ActiveCampaign — but you can't close the loop automatically. This stack connects all three: Plausible fires a goal event when a user reaches a key page, Formbricks uses that signal to trigger an NPS survey, and a Formbricks webhook pushes the response straight into Mautic where a campaign branches on score.
Requires a 16 GB VPS with a dedicated IP — Mautic alone needs 8 GB; adding Billionmail needs the extra headroom
Read the sustainability flags for both tools before committing: Billionmail is early-stage; Mautic has a documented 2026 funding crisis
Mailgun Flex + ActiveCampaign Plus (10k contacts): ~$110/mo; this stack: ~$40–$55/mo on Liquid Web
This guide pairs Billionmail (self-hosted SMTP server) with Mautic (marketing automation) on a single Liquid Web 16 GB VPS. Mautic handles contact segmentation, campaign flows, landing pages, and lead scoring. Billionmail provides the SMTP relay that Mautic sends through.
