Best for when

your newsletter list has grown and the per subscriber bill hurts
you are comfortable setting up an SMTP provider and DNS records
you want subscriber data in your own database

Watch out for

deliverability, bounces and sender reputation are entirely your responsibility
there are no visual automation journeys or landing pages like Mailchimp's
segments are SQL queries, which suits developers more than marketers

Mailing lists without paying per subscriber

Mailchimp and similar services charge by the size of your list, so the bill grows with your audience. Listmonk stores subscribers in your own PostgreSQL database and sends through whatever SMTP provider you choose, so the cost becomes the price of sending, which is far lower with providers such as Amazon SES.

It covers the core: lists, double opt in, subscriber attributes and segments written as SQL queries, templates, campaign analytics, transactional emails through an API, and several SMTP servers at once. It is fast and light, and handles very large lists on modest hardware.

What Mailchimp did for you that you now do

Deliverability becomes your job. You set up SPF, DKIM and DMARC, warm up your sending, handle bounces and complaints, and keep your provider happy. Mailchimp's reputation and compliance team quietly did much of this, and a mistake here sends your newsletter to spam.

It also has no drag and drop email designer as polished as Mailchimp's, no built in landing pages or ad tools, and no visual automation journeys. Segmentation through SQL is powerful for a developer and confusing for a marketer.
