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 Sender?

Sender put its campaign and automation data behind an MCP server, moving reporting out of its own dashboard.

Sender is an email marketing platform that has spent the past year filling in platform basics — transactional email and a rebuilt dashboard in December, a refreshed email builder and brand settings in January, ecommerce reports extended to the Standard plan in March, and a rebuilt subscriber import in August. The newest release breaks that pattern: an MCP server that lets an AI assistant query campaign dashboards, automation reports and prior send history directly.

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.

6.3

Sender put its campaign and automation data behind an MCP server, moving reporting out of its own dashboard.

◆ Current state

Sender is an email marketing platform that has spent the past year filling in platform basics — transactional email and a rebuilt dashboard in December, a refreshed email builder and brand settings in January, ecommerce reports extended to the Standard plan in March, and a rebuilt subscriber import in August. The newest release breaks that pattern: an MCP server that lets an AI assistant query campaign dashboards, automation reports and prior send history directly.

◆ Where it's heading

The platform work was about reaching feature parity with larger competitors. The MCP server is a different kind of move, treating Sender's data as something to be consumed by an assistant the customer already uses rather than only through Sender's interface. Note that the feed mixes tutorials and educational posts with genuine release notes, so cadence here overstates shipping volume.

◆ Prediction

Expect write actions to follow read access — creating campaigns or triggering automations through the same server — since reporting alone is the easier half. The entries do not describe the permission model, which is the part that will determine how far this can go.
