Self-Hosted Email Marketing with Listmonk: Replace Mailchimp

Email marketing is the most cost-sensitive tool in the SaaS stack because it charges per contact. The more successful your audience growth, the more you pay. Listmonk breaks this relationship. Your costs stay flat while your list grows.

The Mailchimp Pricing Spiral

Mailchimp's pricing by contact count: 500 contacts is free. 2,500 contacts costs 35 dollars per month. 5,000 contacts costs 75 dollars. 10,000 contacts costs 100 dollars. 25,000 contacts costs 200 dollars. A growing business that doubles its list in a year doubles its email marketing cost. The tool that helps you grow is also the tool that charges you for growing.

This is not unique to Mailchimp. Every SaaS email marketing platform charges per contact. The business model aligns their revenue with your audience growth. Your success is their upsell.

Listmonk: Self-Hosted, Unlimited Contacts

Listmonk is an open-source email marketing platform that runs on your server. It supports campaigns, automation sequences, transactional emails, list management, and analytics. It handles 100,000 contacts on a 2GB VPS with minimal CPU usage. The software is free. The only cost is the SMTP relay for delivery.

Listmonk features:

• Campaign creation with a drag-and-drop template editor
• Automation sequences (welcome series, drip campaigns)
• List segmentation and management
• Bounce and complaint handling
• Click and open tracking
• Transactional email templates
• REST API for integration with CRM and n8n

SMTP Relay: The Only Cost

You should not send bulk email directly from your server. Deliverability requires a trusted sending IP. Amazon SES charges 10 cents per 1,000 emails. Mailgun charges 80 cents per 1,000 on the flex plan. Postmark charges 1.25 dollars per 1,000. For 10,000 emails per month, the relay cost is 1 to 12.50 dollars. That is the total cost of email marketing with Listmonk. One to twelve dollars per month, regardless of contact count.

Compare to Mailchimp at 100 dollars per month for 10,000 contacts. The saving is 88 to 99 dollars per month. Per year: over 1,000 dollars. For a tool that does the same thing.

Setting It Up

Listmonk deploys via Docker in 10 minutes. Connect it to your SMTP relay, import your contacts, create your first template, and send. The admin interface is clean and straightforward. The documentation is good. The learning curve from Mailchimp to Listmonk is about an hour. After that, the workflow is identical: create campaign, select list, send, review analytics.
