Keila vs MailBeez: at a glance
What is Keila?
Keila adds transactional emails and multi-format templates, broadening past pure newsletters
Keila, an open-source, privacy-focused newsletter tool, made a notable leap in v0.30.0: MJML/HTML/plain-text templates, reusable content slots, and transactional emails — a new product surface beyond bulk campaigns. Surrounding releases add manual contact-status control, API-driven contact events, pre-filled forms, more languages, and a new email scheduler that re-architected the messages schema to enable transactional sending.
What is MailBeez?
MailBeez hardens its big 'V5' rewrite with PHP 8.x compatibility and up-to-10x page-load gains.
MailBeez is a ZenCart email-marketing plugin midway through a major 'V5' platform modernization — redesigned navigation, a marketing calendar, and new flow, audience, and product-review tooling. The most recent releases are the stabilization tail of that push: rapid point releases hardening PHP 7.4-to-8.6 compatibility, ZenCart 2.2.2 support, and large page-load performance improvements.

Keila adds transactional emails and multi-format templates, broadening past pure newsletters
◆ Current state
Keila, an open-source, privacy-focused newsletter tool, made a notable leap in v0.30.0: MJML/HTML/plain-text templates, reusable content slots, and transactional emails — a new product surface beyond bulk campaigns. Surrounding releases add manual contact-status control, API-driven contact events, pre-filled forms, more languages, and a new email scheduler that re-architected the messages schema to enable transactional sending.
◆ Where it's heading
The direction is clear: Keila is evolving from a newsletter sender into a more general email platform. The v0.20.0 scheduler/messages-schema rework laid the groundwork, and v0.30.0 cashed it in with transactional email and flexible templating. Internationalization and API/contact-lifecycle features show parallel investment in reach and automation.
◆ Prediction
Expect transactional email and content-slot templating to mature, with follow-on work on triggered/automated messages now that the messages schema supports them. Continued localization and contact-API expansion are likely.
MailBeez

MailBeez hardens its big 'V5' rewrite with PHP 8.x compatibility and up-to-10x page-load gains.
◆ Current state
MailBeez is a ZenCart email-marketing plugin midway through a major 'V5' platform modernization — redesigned navigation, a marketing calendar, and new flow, audience, and product-review tooling. The most recent releases are the stabilization tail of that push: rapid point releases hardening PHP 7.4-to-8.6 compatibility, ZenCart 2.2.2 support, and large page-load performance improvements.
◆ Where it's heading
The throughline is the V5 rewrite moving from feature delivery into consolidation. After landing the redesigned UI and new marketing tooling in spring, the cadence has shifted to compatibility and performance hardening — isolating Smarty loading, migrating PHP versions, and cutting page-load times by up to 10x. This is the unglamorous but necessary work of making a large rewrite production-solid.
◆ Prediction
Expect continued V5 stabilization point releases focused on compatibility and speed, with remaining legacy flows (e.g. legacy newsletter creation) gradually migrated onto V5.
