A long-quiet cart-recovery tool resurfaces with a 5.0 experience refresh.
A side-by-side editorial comparison of SalesBlink and Keila — release velocity, themes, recent moves, and the top alternatives to consider.
SalesBlink is turning cold outreach into something an AI agent can run.
SalesBlink is a cold-email outreach platform, and its recent work splits along two lines: making itself agent-operable and improving deliverability. It shipped an MCP server so external agents can drive campaigns, followed by an OpenClaw integration built on top of it. On deliverability, it added security-gateway skipping, inbox placement testing, and preconfigured mailboxes for cold outreach.
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.

It shipped an MCP server so external agents can drive campaigns, followed by an OpenClaw integration built on top of it. On deliverability, it added security-gateway skipping, inbox placement testing, and preconfigured mailboxes for cold outreach.
The directional bet is agent-operability: exposing the outreach engine over MCP repositions SalesBlink from a dashboard product to a set of tools an AI agent can call, and the OpenClaw integration is the first proof of that. The deliverability work — gateways, placement tests, mailboxes — is the complementary track, keeping the sends that agents trigger actually landing in inboxes.
Expect more agent-facing tooling and MCP capability alongside continued deliverability infrastructure, as SalesBlink leans into being the outreach layer an agent operates.
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.
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.
