SalesBlink vs Keila
Side-by-side trajectory, velocity, and editorial themes.
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.
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 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.
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.
