Keila vs SalesBlink: 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 SalesBlink?
SalesBlink is making agents first-class clients, and just broke API-key MCP connections to do it
SalesBlink is cold-email outreach software shipping monthly roundups plus one-off announcements. The recent run is dominated by machine access: an MCP server, a CLI, an integration letting Hermes agents run outreach, and now OAuth on the MCP server with 40-plus upgraded tools spanning sequences, leads, inbox, senders and analytics. The rest is polish — Slack alerts over OAuth, branded meeting invites, attachments in replies, faster reply detection.

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.

SalesBlink is making agents first-class clients, and just broke API-key MCP connections to do it
◆ Current state
SalesBlink is cold-email outreach software shipping monthly roundups plus one-off announcements. The recent run is dominated by machine access: an MCP server, a CLI, an integration letting Hermes agents run outreach, and now OAuth on the MCP server with 40-plus upgraded tools spanning sequences, leads, inbox, senders and analytics. The rest is polish — Slack alerts over OAuth, branded meeting invites, attachments in replies, faster reply detection.
◆ Where it's heading
The product is being rebuilt so an agent can operate it end to end rather than trigger it. OAuth removes the API-key copy-paste that made MCP setup a chore, a single endpoint replaces per-client configuration, and the tool count suggests most of the app's surface is now callable. Notably the change is breaking: existing API-key MCP connections have stopped working and must be reconnected, which is a cost SalesBlink was willing to impose to get agent access onto a proper auth flow.
◆ Prediction
With OAuth and 40-plus tools in place, the next constraint is what an agent is allowed to do rather than what it can reach, so expect scoped permissions or approval steps on the sending actions before the outreach ones get widely used unattended.
