A side-by-side editorial comparison of MailerLite and Keila — release velocity, themes, recent moves, and the top alternatives to consider.
MailerLite vs Keila: at a glance
What is MailerLite?
MailerLite rebuilds its email editors with an AI HTML agent and deepens e-commerce automation.
MailerLite is broadening its email-marketing platform across three fronts: email authoring, e-commerce automation, and digital-product selling. Recent releases rebuilt both email editors (including an AI-assisted HTML editor), split and expanded e-commerce automation triggers, and streamlined brand-style management directly inside the builder.
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.

MailerLite
5.0MKT AUTO
MailerLite rebuilds its email editors with an AI HTML agent and deepens e-commerce automation.
◆ Current state
MailerLite is broadening its email-marketing platform across three fronts: email authoring, e-commerce automation, and digital-product selling. Recent releases rebuilt both email editors (including an AI-assisted HTML editor), split and expanded e-commerce automation triggers, and streamlined brand-style management directly inside the builder.
◆ Where it's heading
The direction is a more self-serve, AI-assisted creator-and-commerce suite: prompt-driven HTML email building, tighter product-to-automation flows (promote a Stripe product into a campaign in a few clicks), and richer e-commerce triggers. Expect continued investment in AI-in-the-editor and monetization features for creators selling digital products.
◆ Prediction
Next likely moves: extending the in-editor AI agent beyond HTML into broader content generation, and deepening digital-product and commerce automation now that Stripe-backed product promotion is in place.
Keila
6.3MKT AUTO
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.
