The week in marketing-automation

Agent runtimes are the story. n8n and Gumloop both shipped the controls an automation needs before it can be trusted to act alone: spend caps, resumable runs and credential ownership.

The rest of the sector was patch trains and polish, with one sharp reminder from n8n that deprecated nodes are no longer tolerated.

Leaders

n8n 2.43 put a guardrail runner in the agent loop, an opt-in budget guardrail that caps agent runs, an instance setting for Agents and resumable executions. Patches since then made the agent builder prompt static so providers can cache it, and 2.43.3 started refusing to save workflows built on deprecated nodes.

Gumloop 12.0 gave agents a real browser to click, type, sign in and download on any site, with or without a connector. Version 12.2 then added agent-owned secrets, so everyone using a custom agent runs with the same credential, and admins can force an agent's settings.

Nutshell is a CRM that shows up here for Smart Sequences, email campaigns that branch on opens and clicks. It also reworked its QuickBooks Online handoff and, most recently, added a CallRail integration that ties inbound calls to marketing sources.

Wildcards

Formidable Forms ships through add-ons: Stripe Forms v3.2 moves off the deprecated handleCardPayment API to confirmCardPayment, and Conversational Forms v1.3 adds draft save and resume. Dropping a deprecated payment path is the least visible but most important of the week.

Pimcore is a weekly patch train, but 2026.2.12 patched a code-generation RCE and a video XSS advisory, which makes it the one release in the sector that readers on that line should act on.

Themes that compounded

  • Controls arriving alongside capability: budgets at n8n, secrets at Gumloop.
  • Deprecated paths becoming enforced, not just flagged, at n8n and Formidable Forms.
  • Daily correctness fixes for email clients and embedded forms at Buttondown.

Watch this week

Watch whether n8n 2.43 patches keep landing identical changes on the 2.42 line, which would signal how long the old agent runtime is supported. Gumloop ships weekly, so a 12.3 should say whether the agent-owned secrets story gains audit features. Moosend shipped no product release in its feed, only blog posts.
