How to Build Your Own Email Newsletter Service Without Mailchimp (Using Mautic, Mailtrain, or Listmonk)?
Greetings, friends!
Using cloud-based email marketing platforms (SaaS) like Mailchimp, Brevo, or ActiveCampaign quickly becomes financially impractical as your subscriber base grows. Once you cross the threshold of 10,000 to 50,000 contacts, monthly bills can easily reach hundreds of dollars. Furthermore, SaaS platforms dictate strict moderation policies and can suspend or block accounts without prior notice.
Switching to self-hosted email marketing solutions gives you full ownership of your data, ensures GDPR compliance, and reduces email marketing expenses by 5 to 10 times. In this article, we will compare three of the top open-source platforms—Mautic, Mailtrain, and Listmonk—and explain how to deploy your own newsletter infrastructure.
Key Takeaways: Core Conclusions
Save up to 90% of your budget: With a self-hosted platform, you only pay for your virtual private server (VPS) and outgoing SMTP traffic (via Amazon SES, Postmark, or SendGrid), rather than the total number of contacts in your database.
Platform selection depends on your needs:
Listmonk: The undisputed winner in speed and resource efficiency (written in Go). Ideal for straightforward newsletter distribution and transactional emails. It is my personal favorite because it is exceptionally easy to install, configure, and use.
Mautic: A comprehensive marketing automation suite (funnels, lead scoring, web behavior tracking).
Mailtrain: A balanced Node.js solution featuring a user-friendly editor and segmentation tools.
IP reputation is the ultimate success factor: Deliverability depends not on the software choice, but on proper cryptographic authentication (SPF, DKIM, DMARC) and maintaining a clean IP address.
Video Installation Guides
We have published video guides on our YouTube channel covering the installation of various email marketing tools. You can watch two of them right here:
Self-Hosted Email Infrastructure Architecture
An autonomous email marketing system consists of two distinct components:
Email Marketing Engine (Mautic / Mailtrain / Listmonk): The control panel installed on your VPS. It manages subscriber lists, opt-in forms, segmentation, visual email creation, open/click analytics, and automated workflows.
SMTP Relay Provider (Transport Gateway): A specialized delivery service (Amazon SES, SendGrid, Mailgun) or an in-house mail server. It delivers generated messages directly to recipient mailboxes (Gmail, Outlook, etc.).
Open-Source Platform Comparison
| Evaluation Criterion | Listmonk | Mailtrain | Mautic |
| Tech Stack | Go + PostgreSQL | Node.js + MySQL/MariaDB | PHP + MySQL/MariaDB |
| RAM Consumption | Minimal (~20–50 MB) | Moderate (~150–300 MB) | High (~500 MB – 1 GB+) |
| Sending Speed | Ultra-high (10,000+ emails/min) | Medium | Moderate |
| Setup Complexity | Low (single binary or Docker) | Medium | High |
| Primary Focus | Mass newsletters, transactional emails | Standard email marketing | Comprehensive Marketing Automation |
1. Listmonk — Maximum Speed and Minimalism
If your goal is to regularly dispatch digests, newsletters, or transactional messages to hundreds of thousands of contacts, Listmonk is unmatched. Built with Go, it consumes minimal system resources, processes massive databases instantly, and supports integrations via REST APIs and Go templates.
From my personal experience, I have tested various email sending tools, but I ultimately chose Listmonk because of its simplicity. Adding subscribers, modifying SMTP settings, drafting emails, sending campaigns, and tracking opens, clicks, and link conversions is incredibly straightforward. If you are looking for a solution that can be set up in under 5 minutes, Listmonk is the best choice.
2. Mailtrain — Classic Email Marketing
Mailtrain offers an interface that closely mirrors Mailchimp. It includes a visual email builder (GrapesJS), custom subscriber fields, automated unsubscribe processing, and bounce handling.
3. Mautic — Full Alternative to HubSpot and ActiveCampaign
Mautic is far more than a newsletter tool—it is a complete customer relationship management suite. It allows you to track visitor activity on your website, build conditional email sequences based on user actions (Campaign Builder), assign engagement scores (Lead Scoring), and sync data with CRM systems.
Checklist: Server Preparation and Deliverability Setup
To ensure your emails land in the primary Inbox rather than the Spam folder, complete these steps before sending campaigns:
Deploy via Docker: Using Docker and Docker Compose is the fastest way to deploy Listmonk or Mailtrain in 5 minutes without manual web server or database configurations.
Configure Domain DNS Records (Crucial):
SPF (Sender Policy Framework): Specifies which SMTP servers are authorized to send email on behalf of your domain.
DKIM (DomainKeys Identified Mail): A cryptographic signature verifying that the email was not altered in transit.
DMARC: A policy instructing receiving mail providers (Gmail, Yahoo) how to handle failed SPF/DKIM checks.
Configure Reverse DNS (PTR Record): Ensure your VPS PTR record matches your server's FQDN (especially relevant when sending via your own SMTP server).
Warm Up Your IP Address (IP Warm-up): Avoid sending 50,000 emails on day one from a new IP or Amazon SES account. Start with 300–500 emails per day and gradually increase daily volume by 20–30%.
FAQ: Frequently Asked Questions
Can I send emails directly from a VPS without Amazon SES or SendGrid?
Technically yes (by configuring Postfix or Exim), but practically it is not recommended. Public VPS IP ranges often carry baseline neutral or poor reputations in anti-spam databases. Using specialized SMTP relays (such as Amazon SES at $0.10 per 1,000 emails) guarantees high deliverability while protecting your primary server IP. Personally, I use SendGrid—it is very convenient and offers affordable plans.
How difficult is it to migrate from Mailchimp to Listmonk or Mautic?
Exporting your contacts from Mailchimp takes a simple CSV export. All three platforms (Listmonk, Mailtrain, Mautic) support CSV imports with custom fields (name, registration date, tags). Setting up the basic infrastructure typically takes between 1 and 3 hours.
What VPS specs are required to run Listmonk or Mautic?
For Listmonk, an entry-level server with 1 vCPU and 1 GB RAM is sufficient to handle hundreds of thousands of contacts. For Mautic, due to heavy database queries, caching, and background Cron jobs, a minimum of 2 vCPUs and 2–4 GB RAM is recommended.
Conclusion
Building your own email infrastructure using Mautic, Mailtrain, or Listmonk is an effective move toward financial independence from SaaS vendors and complete control over customer data privacy. You gain a platform free from contact limits or per-recipient surcharges.
The key factors for maintaining a stable self-hosted email service are high disk I/O performance for database operations and reliable network connectivity.
