The short version

  • Each has a real cost: Corteza planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.; Listmonk it is not an email service provider. It hands mail to SMTP servers you configure and does nothing about IP warm-up, domain reputation, DKIM, DMARC or inbox placement, so deliverability failures are entirely yours to diagnose and fix.
  • They diverge on capability: Corteza covers Corteza Low Code, Listmonk covers Single binary deployment.
  • Prices and features above were last checked on 31 August 2026.

  • A developer wants campaign audiences defined by an arbitrary SQL query against subscriber attributes, which no hosted segment builder will express.not Corteza
  • An organisation under privacy or data residency rules needs subscriber data to stay on infrastructure it controls, which rules out every hosted newsletter platform.not Corteza
  • An open source project or nonprofit needs a mailing list tool with no per-subscriber cost, where the list will grow faster than any budget for it.not Corteza

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Corteza

  • Planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond.
  • No pricing is published for Planet Crusts support, hosting or implementation services, so the true running cost of a supported deployment cannot be estimated without a sales conversation.
  • The connector ecosystem is small compared with commercial low-code platforms, so integrations with common SaaS tools usually mean writing against the REST API rather than installing something.
  • Hiring is hard: almost nobody has Corteza on a CV, so you are training internal developers on a niche platform and you cannot easily replace them.
  • The bundled CRM is a starting point rather than a mature product, and teams that expect Salesforce-equivalent sales functionality out of the box will spend months building the gap themselves.

Listmonk

  • It is not an email service provider. It hands mail to SMTP servers you configure and does nothing about IP warm-up, domain reputation, DKIM, DMARC or inbox placement, so deliverability failures are entirely yours to diagnose and fix.
  • Running it means running PostgreSQL, backups, upgrades and a mail relay, and the true cost is the engineering time to keep that stack healthy rather than the zero licence fee.
  • The campaign editor and analytics are basic next to Mailchimp or Klaviyo: reporting is limited to opens, clicks and bounces, with no revenue attribution, no ecommerce integration and no deep engagement scoring.
  • SQL-based segmentation puts audience definition beyond a non-technical marketer, so a marketing team without engineering support will be blocked on routine tasks.
  • The AGPLv3 licence obliges you to release source modifications if you offer the software as a network service, which is a real constraint for anyone considering embedding it in a commercial product.

Answered from the vendors’ own pages

Corteza: Is Corteza the same thing as Crust?

Yes. The project was branded Crust and renamed Corteza in 2019 when Crust Technology donated it to the Commons Conservancy.

Listmonk: Does Listmonk send my emails?

No. It composes, queues and tracks campaigns, then hands the messages to SMTP servers you provide, such as Amazon SES, Postmark or your own relay.

Corteza: Who owns the code?

The Commons Conservancy, a Dutch foundation. Planet Crust in Cork is the primary developer and sells commercial services around it.

Listmonk: What does it cost to run?

The software is free. The real cost is a small server, a PostgreSQL database and per-email SMTP charges, which through SES are a fraction of hosted newsletter pricing at large list sizes.

Corteza: Is there a paid enterprise edition?

No. Corteza is Apache 2.0 with no feature gating. Planet Crust sells support, hosting and development instead of a restricted edition.

Listmonk: What licence is it under?

AGPLv3, which requires you to publish modifications if you offer it as a network service to others.

Corteza: Can it genuinely replace Salesforce?

For case management and a straightforward sales pipeline on a self-hosted footprint, yes. For a large sales organisation relying on AppExchange products and a mature ecosystem, no.

Listmonk: Is there an official hosted version?

No. Some unaffiliated providers offer managed Listmonk, but the maintainer does not run a hosted service.
