Formidable Forms
WordPress form builder ships a steady security-and-refinement cadence.
A side-by-side editorial comparison of Keila and MailerLite — release velocity, themes, recent moves, and the top alternatives to consider.
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.
MailerLite keeps folding e-commerce and creator monetization into its editor-first core.
MailerLite is steadily extending from newsletter tooling into commerce automation and creator monetization. Recent work deepens store integrations (variant-level purchase triggers, split abandoned-cart vs. abandoned-checkout flows) while modernizing the editing surface with new Simple and Custom HTML editors and account-wide brand styles.

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.
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.
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.
MailerLite is steadily extending from newsletter tooling into commerce automation and creator monetization. Recent work deepens store integrations (variant-level purchase triggers, split abandoned-cart vs. abandoned-checkout flows) while modernizing the editing surface with new Simple and Custom HTML editors and account-wide brand styles.
The product is converging on a single pattern: let a solo creator or small store sell and automate without leaving the email builder. Expect continued investment in store-data plumbing (more platforms beyond Wix) and Stripe-backed product promotion, paired with UX cleanup that pulls settings like brand styles closer to where users actually work.
The variant-trigger rollout beyond Wix (Shopify, WooCommerce, BigCommerce) is the clearest near-term step, alongside more automation templates tied to digital-product sales.
