What is Smartlead?
Smartlead is rebuilding outbound around AI operators, voice and a programmable surface.
Smartlead has shipped three significant new product surfaces in the last quarter: SmartAgents (AI operators that own outbound workflows end-to-end), SmartDialer (voice-driven outreach with auto-logged context), and a Smartlead CLI plus MCP server for programmatic and AI-driven control. Around them, the team continues to broaden multichannel coverage (HeyReach and Aimfox for LinkedIn) and tighten developer ergonomics (per-integration API keys).
What is Umbraco CMS?
Umbraco 19 reaches its first release candidate on .NET 11 GA.
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.

Smartlead
1.3MARKETING
Smartlead is rebuilding outbound around AI operators, voice and a programmable surface.
◆ Current state
Smartlead has shipped three significant new product surfaces in the last quarter: SmartAgents (AI operators that own outbound workflows end-to-end), SmartDialer (voice-driven outreach with auto-logged context), and a Smartlead CLI plus MCP server for programmatic and AI-driven control. Around them, the team continues to broaden multichannel coverage (HeyReach and Aimfox for LinkedIn) and tighten developer ergonomics (per-integration API keys).
◆ Where it's heading
Smartlead is moving past 'better cold email tool' into 'AI-operated GTM stack'. The throughline: every new surface is something an AI agent can drive — agents creating campaigns and handling replies, voice calls happening at intent spikes with auto-CRM updates, the same actions invokable from a CLI or via MCP. Multichannel integrations (LinkedIn, voice, email) feed a single agent-controllable system rather than separate tools.
◆ Prediction
Expect deeper agent autonomy — SmartAgents handling more decision steps unattended, voice and email coordinated by the same agent — plus expansion of the MCP/CLI surface into adjacent vendor data (Clay, enrichment, CRM writes). Watch for pricing that reframes around agent actions or workflows completed rather than emails sent.
Umbraco CMS
6.3MARKETING
Umbraco 19 reaches its first release candidate on .NET 11 GA.
◆ Current state
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.
◆ Where it's heading
The 19 cycle is moving quickly from beta to candidate, and rc1 is about hardening rather than new editor features: dependencies on GA, environment-level permissions and load-balancing performance. The 17 and 18 lines are kept in step on security fixes while 19 matures.
◆ Prediction
Expect 18.3 and 17.8 to go stable, followed by further 19 release candidates and a 19.0.0 stable release built on .NET 11.
