Django-CRM bakes in mass email marketing
Django-CRM ships with built-in mass mailing and email marketing capabilities, an unusually strong feature for an open-source CRM since many competitors require a separate email tool.

Odoo CRM adds machine-learning lead scoring for free
Odoo CRM includes predictive lead scoring trained on historical CRM data, available even on the free One App Free plan with unlimited users.
Odoo CRM
Corteza bundles a low-code builder and messaging with CRM
Corteza combines its CRM module with a general-purpose low-code app builder and Slack-like enterprise messaging in one self-hosted platform, going beyond CRM alone.
Corteza
Odoo CRM's payoff grows with the rest of the suite
Closed opportunities in Odoo CRM can automatically generate quotes, sales orders, and invoices, a benefit that compounds as a business adopts more Odoo apps.
Odoo CRM
Corteza and Django-CRM carry zero licensing cost by design
Both are fully open source with no paid CRM tier of their own; Odoo CRM's free tier covers only the CRM app, with paid plans required to unlock the rest of the suite.

Corteza and Django-CRM are fully free and open source with no paid CRM tier of their own, though Corteza offers optional paid support and hosting through Planet Crust. Odoo CRM is free for unlimited users on the One App Free plan, but unlocking the rest of the Odoo suite requires the paid Standard or Custom plans.
Django-CRM leans on the well-documented Django ecosystem and standard Python deployment conventions, which can lower operational risk for teams already comfortable with Django. Corteza requires Go/Docker or Kubernetes familiarity, and Odoo CRM can be self-hosted or run on Odoo Online hosting included with paid plans.
Django-CRM includes built-in mass mailing and email marketing functionality directly in the platform. Odoo's marketing automation is a separate app rather than a core CRM feature, and Corteza's provided feature set does not document built-in email marketing.
Odoo CRM is designed to scale into a full ERP: closing a deal can automatically generate a quote, sales order, stock reservation, and invoice as a business adopts more Odoo apps. Corteza and Django-CRM are CRM/low-code tools without that native ERP quote-to-cash integration.
Corteza and Django-CRM both require in-house or contracted DevOps and, for Django-CRM, Python/Django expertise to install, customize, and maintain. Odoo CRM can be adopted with less technical overhead via its paid Odoo Online hosting.
Only Odoo CRM includes documented machine-learning-based predictive lead scoring, trained on a company's historical CRM data to estimate the probability of winning each opportunity.
