Great question! Here's what's currently available for working with email in Hub via API and MCP:

API
- Docs are at decilehub.com/api/docs
- You can create/update prospects via POST /api/v1/pipeline_prospect (matches on email), including adding notes that feed into AI email generation
- API tokens are in Settings > API > API Tokens (requires a paid subscription)

MCP
- MCP server details are at decilehub.com/api/settings
- Note: there was a known bug where the MCP create_or_update_prospect tool used a people parameter instead of prospects — worth checking if that's been resolved for you

Email campaigns in Hub
- Link-click automations can move prospects between pipeline stages automatically
- You can set up follow-on automated email tasks to build drip sequences
- Gmail 2-way sync (via Integrations in the top right) pulls email history into Hub and feeds AI email generation
- AI email generation uses your notes, past emails, and prospect context

Gaps to be aware of
- No individual read receipts (tracking pixels used in newsletters only)
- Shared mailbox support is limited depending on your email provider

If there are specific API/MCP email campaign capabilities you'd like exposed that aren't there yet, feel free to share the details and we'll look into it!
