SalesBlink vs SendPortal: at a glance
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.
What is SendPortal?
SendPortal hasn't tagged a release since July 2020.
The only tracked release is v1.0.3 from July 2020, which removed the laracatch-client dependency. No later tags appear in the feed, so for tracking purposes the project looks dormant.

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.
