SalesBlink rebuilds warmup, binds AI emails to brand guardrails, and connects to ChatGPT.
SalesBlink is a cold-email outreach tool that now ships monthly roundups on top of individual launches. October brought out-of-office rescheduling, a Business Profile whose guardrails AI-written emails must follow, a rebuilt warmup engine that adapts ramp-up to spam placement, and ChatGPT and Perplexity connectors over its OAuth MCP server. It follows September's Outreach and Reply Agents and a faster Inbox.
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.

The product is layering AI writing and reply handling on top of the developer surfaces (API, MCP, CLI) it built in August and September. Deliverability is the other constant: warmup, sender-health alerts, overlap warnings and one-click unsubscribe all aim at keeping volume out of spam.
Expect further Outreach Agent controls, which September's roundup promised for October, and more actions exposed through the MCP connectors as they reach more assistants.

Since 13.2 the releases have moved from what agents can do toward how a company controls them. 13.6 is the broadest step yet: approval rules, data redaction and secret handling now cover all agent activity, which is what security teams ask for before a wide rollout.
Expect Workforce Atlas to leave beta with more tags and reporting, and more enterprise controls such as audit exports built on the new guardrail records.
