Sends the cleaned body as iMessage to that phone via Blooio.\n3. Forwards inbound iMessages back to the user's inbox, with Reply-To set so replies loop back.\n4. Logs the iMessage to the matching Close lead's timeline.\n\n### Setup steps\n\n- [ ] Connect a bridge Gmail credential to \"When Email Received\" and \"Send Email to Inbox\".\n- [ ] Connect a Blooio credential to \"Send iMessage via Blooio\" and register the webhook URL for message.received.\n- [ ] Connect a Close API credential to \"Find Lead in Close by Phone\" and \"Log iMessage to Close\".\n- [ ] Fill the inbox + bridge placeholders, send a test, then toggle Active.\n\n### Customization\n\n- Swap Close for any CRM by replacing the two HTTP Request nodes.\n- Add HMAC verification on the inbound webhook for production hardening\n\n\n## Learn more at [SMB Excel](https://www.smbexcel.com)"
