Pros & Cons
listmonk
Pros
- The software has no licence or per-subscriber fees. A reviewer estimates 100,000 subscribers on weekly sends costs about 45 USD a month in hosting and SES fees.
- Reviewers report it handles hundreds of thousands to millions of subscribers on modest hardware.
- Multi-SMTP queues with rate limiting let you mix providers such as SES, Postmark or Mailgun.
- SQL-based segmentation and Go templating give developers very fine control.
- It includes a transactional API, OIDC SSO, role-based permissions and scoped API tokens.
Cons
- You must set up and run Docker or the binary, PostgreSQL, a reverse proxy and SMTP yourself.
- Support comes only from the community on GitHub, with no SLA.
- It has no behavioural automation or drip sequences.
- Deliverability and list cleaning depend on your own DNS and provider configuration.
- Reviewers say it has fewer integrations, templates and tutorials than commercial platforms.
