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 Gumloop?
Gumloop is building the operational layer to run custom agents across an organization
Gumloop is building out the operational layer around custom agents. The latest release adds Claude Sonnet 5 and agent-owned credentials, on top of recent work on per-agent analytics, org-wide credit insights, and connector access requests. MCP connectivity keeps widening — live artifacts can now reach all connected MCP servers.

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.

Gumloop is building the operational layer to run custom agents across an organization
◆ Current state
Gumloop is building out the operational layer around custom agents. The latest release adds Claude Sonnet 5 and agent-owned credentials, on top of recent work on per-agent analytics, org-wide credit insights, and connector access requests. MCP connectivity keeps widening — live artifacts can now reach all connected MCP servers.
◆ Where it's heading
The platform is moving from 'build an agent' to 'run agents across an organization': analytics, credit visibility, access control, and multi-channel triggers (Slack, Teams) point squarely at team and admin needs. Adopting frontier models quickly and deepening MCP support keeps Gumloop current as an agent execution layer.
◆ Prediction
Expect more governance and observability around agents — per-agent cost controls and audit — plus continued fast adoption of new models and MCP capabilities.
