What is Keila?

Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.

Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.

What is SalesBlink?

SalesBlink ships a CLI — cold email outreach now scriptable from the terminal and CI/CD pipelines

SalesBlink has launched a command-line interface exposing sequences, leads, lists, senders, templates, inbox, and inbox placement tests from the terminal — built explicitly for automation scripts and CI/CD pipelines. The MCP server was upgraded to OAuth the same week, making AI agent connections possible without copying API keys, and it now works across Claude, ChatGPT, Cursor, Codex, Windsurf, and Copilot.

Keila v0.30.3 adds Liquid template caching for measurably faster campaign renders on large lists.

◆ Current state

Keila is a steady open-source email newsletter platform built on Elixir/Phoenix, shipping incremental quality improvements. v0.30.3 (the most recent release) adds campaign ID as a template variable, introduces TLS/STARTTLS and SMTP authentication environment variables for system mailer configuration, adds Liquid template caching (described as a significant render performance improvement for large campaigns), and accelerates several queries across large projects.

◆ Where it's heading

Keila's recent releases — v0.30.0's transactional email API, v0.20.0's new email scheduler, and now v0.30.3's performance work — show a project that is consolidating its architecture before broadening its feature set. The self-hosting focus remains; the additions to system mailer configurability suggest the project is listening to operators running Keila in production with non-standard SMTP setups.

◆ Prediction

Transactional email capabilities from v0.30.0 will likely expand — more API endpoints, webhook delivery events, or better unsubscribe handling for transactional vs. campaign messages. Performance tooling for large lists will continue as the Liquid caching work surfaces the right optimization targets.

SalesBlink ships a CLI — cold email outreach now scriptable from the terminal and CI/CD pipelines

◆ Current state

SalesBlink has launched a command-line interface exposing sequences, leads, lists, senders, templates, inbox, and inbox placement tests from the terminal — built explicitly for automation scripts and CI/CD pipelines. The MCP server was upgraded to OAuth the same week, making AI agent connections possible without copying API keys, and it now works across Claude, ChatGPT, Cursor, Codex, Windsurf, and Copilot.

◆ Where it's heading

SalesBlink has built three developer surfaces in rapid succession: REST API, MCP server, and CLI. Each release expands the automation footprint — the pattern points toward a product betting that AI agents and automated pipelines, not sales reps manually building sequences, will become the primary customer use case for email outreach.

◆ Prediction

The natural next step is a native AI workflow template or agent skill that lets Claude, Cursor, or a similar tool build and launch a full email sequence end-to-end using the CLI or MCP surface with no manual UI interaction.
