Form submission email notifications never sent — submissions captured fine, no email dispatched

Site: statelinehomebuyers-preview (site ID 6811de1a-7eb3-45a6-947e-483b6f0b2059, custom domain statelinehomebuyers.net)

Form detection is enabled and working — 8 forms registered, submissions are captured and visible in the dashboard as verified submissions.

The problem: no form submission notification email is ever sent. I have tested:

  1. An email notification for “New form submission” / Any form → andrew@statelinehomebuyers.net (Google Workspace; MX confirmed working, mailbox accepts delivery).
  2. A second notification → a plain Gmail address.
  3. Notifications were created both via the API and re-saved through the dashboard UI.
  4. Multiple verified (non-spam) test submissions after each change.

Result: nothing arrives at either address — inbox or spam — from formresponses@netlify.com, hours later. Both addresses receive mail from other senders normally.

Could you check whether these recipient addresses are on a suppression/bounce list, or whether email notifications are otherwise disabled for this site/account? This is a lead-capture form for a small business, so notification delivery matters a lot to us.

Thanks!
