Make a checked Gmail follow-up draft from Notion and HubSpot

Connect Notion, HubSpot and Gmail to Claude Code, reconcile an approved brief with exact CRM and email records, and verify one human-reviewed Gmail follow-up draft.

The big change

What changed: Claude Code can use a direct Notion MCP connection and inherit authenticated HubSpot and Gmail connectors from the same Claude.ai subscription login.

Why it matters: The writer can compare a brief, CRM records and the actual email thread before composing one draft, then use Gmail's draft readback to inspect what was saved.

What to watch: Connector access is broader than the records named in a prompt. Confirm the account and grants, get approval for the exact recipients and text, and treat a timed-out draft write as unknown until Drafts has been inspected.

The big change

What changed: Opus 4.7 uses claude-opus-4-7, rejects manual thinking budgets and speed: "fast", and uses a different tokenizer. Sampling-key rules also depend on the effective API version.

Why it matters: Request validity, response handling, token thresholds and task outcomes all need checking before the owner changes serving traffic.
